• Apache Won't Restart After Compiling PHP with Postgres

  - by gonzofish

  I've compiled PHP (v5.3.1) with Postgres using the following configure: ./configure \ --build=x86_64-redhat-linux-gnu \ --host=x86_64-redhat-linux-gnu \ --target=x86_64-redhat-linux-gnu \ --program-prefix= \ --prefix=/usr/ \ --exec-prefix=/usr/ \ --bindir=/usr/bin/ \ --sbindir=/usr/sbin/ \ --sysconfdir=/etc \ --datadir=/usr/share \ --includedir=/usr/include/ \ --libdir=/usr/lib64 \ --libexecdir=/usr/libexec \ --localstatedir=/var \ --sharedstatedir=/usr/com \ --mandir=/usr/share/man \ --infodir=/usr/share/info \ --cache-file=../config.cache \ --with-libdir=lib64 \ --with-config-file-path=/etc \ --with-config-file-scan-dir=/etc/php.d \ --with-pic \ --disable-rpath \ --with-pear \ --with-pic \ --with-bz2 \ --with-exec-dir=/usr/bin \ --with-freetype-dir=/usr \ --with-png-dir=/usr \ --with-xpm-dir=/usr \ --enable-gd-native-ttf \ --with-t1lib=/usr \ --without-gdbm \ --with-gettext \ --without-gmp \ --with-iconv \ --with-jpeg-dir=/usr \ --with-openssl \ --with-zlib \ --with-layout=GNU \ --enable-exif \ --enable-ftp \ --enable-magic-quotes \ --enable-sockets \ --enable-sysvsem \ --enable-sysvshm \ --enable-sysvmsg \ --with-kerberos \ --enable-ucd-snmp-hack \ --enable-shmop \ --enable-calendar \ --with-libxml-dir=/usr \ --enable-xml \ --with-system-tzdata \ --with-mime-magic=/usr/share/file/magic \ --with-apxs2=/usr/sbin/apxs \ --with-mysql=/usr/include/mysql \ --without-gd \ --with-dom=/usr/include/libxml2/libxml \ --disable-dba \ --without-unixODBC \ --disable-pdo \ --enable-xmlreader \ --enable-xmlwriter \ --without-sqlite \ --without-sqlite3 \ --disable-phar \ --enable-fileinfo \ --enable-json \ --without-pspell \ --disable-wddx \ --with-curl=/usr/include/curl \ --enable-posix \ --with-mcrypt \ --enable-mbstring \ --with-pgsql=/mnt/mv/pgsql I'm using Postgres 8.4.0 and Apache 2.2.8; I have the following line in my Apache conf file: LoadModule php5_module /usr/lib64/httpd/modules/libphp5.so And when I attempt to restart Apache, I get the following error message: Starting httpd: httpd: Syntax error on line 205 of /etc/httpd/conf/httpd.conf: Cannot load /usr/lib64/httpd/modules/libphp5.so into server: /usr/lib64/httpd/modules/libphp5.so: undefined symbol: lo_import_with_oid Now, I know that this is a problem with Postgres with PHP because lo_import_with_oid is a function in the Postgres source which allows the importing of large objects; also, if I remove the --with-pgsql option, PHP and Apache get along great. I've scoured the Internet looking for answers all day, but to no avail. Does anyone have ANY insight into what is causing my problems.

• Experience with AMCC 3ware 9650se raid cards? Ours seems dead

  - by antiduh

  We have a 8-port 3ware 9650se raid card for our main disk array. We had to bring the server down for a pending power outage, and when we turned the machine back on, the raid card never started. This card has been in service for a couple years without problems, and was working up until the shutdown. Now, when we turn the machine on, the bios option rom that normally kicks in before the bootloader doesn't show up, none of the drives start, and when the OS tries to access the device, it just times out. The firmware on it has been upgraded in the past, so it's possible we've hit some sort of firmware bug. We're using it in a Silicon Mechanics R272 machine with gentoo for the OS. The OS eventually boots, but alas, without the card. We've ordered a new one, but I'm worried that if we replace the card it won't recognize the existing array. Has anybody performed a card swap before? Any help would be greatly appreciated. Edit: These are the kernel errors we see: 3ware 9000 Storage Controller device driver for Linux v2.26.02.012. 3w-9xxx 0000:09:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18 3w-9xxx 0000:09:00.0: setting latency timer to 64 3w-9xxx: scsi0: ERROR: (0x06:0x000D): PCI Abort: clearing. 3w-9xxx: scsi0: ERROR: (0x06:0x001F): Microcontroller not ready during reset sequence. 3w-9xxx: scsi0: ERROR: (0x06:0x0036): Response queue (large) empty failed during reset sequence. 3w-9xxx 0000:09:00.0: PCI INT A disabled

• NFS v4, HA Migration, and stale handles on clients

  - by Karl Katzke

  I'm managing a server running NFS v4 with Pacemaker/OpenAIS. NFS is configured to use TCP. When I migrate the NFS server to another node in the Pacemaker cluster, even though the metadata is persisted, connections from the clients 'hang' and eventually time out after 90 seconds. After that 90 seconds, the old mountpoint becomes 'stale' and the mounted files can no longer be accessed. The 90 second grace period seems to be part of the server configuration and not the client configuration. I see this message on the server: kernel: NFSD: starting 90-second grace period If I restart the NFS client on the client nodes after I migrate (unmounting and then remounting the share), then I don't experience the problem, but connections and file transfers still interrupted. Three questions: What is the 90 second grace period? What's it there for? How can I keep the files from going stale on the clients without restarting them after I migrate the NFS server to another node? Is it actually possible to migrate the NFS server without having large file uploads drop?

• How can the little guys effectively learn and use puppet?

  - by drumfire

  Six months ago, in our not-for-profit project we decided to start migrating our system management to a Puppet controlled environment because we are expecting our number of servers to grow substantially between now and a year from now. Since the decision has been made our IT guys have become a bit too annoyed a bit too often. Their biggest objections are: "We're not programmers, we're sysadmins"; Modules are available online but many differ from one another; wheels are being reinvented too often, how do you decide which one fits the bill; Code in our repo is not transparent enough, to find how something works they have to recurse through manifests and modules they might have even written themselves a while ago; One new daemon requires writing a new module, conventions have to be similar to other modules, a difficult process; "Let's just run it and see how it works" Tons of hardly known 'extensions' in community modules: 'trocla', 'augeas', 'hiera'... how can our sysadmins keep track? I can see why a large organisation would dispatch their sysadmins to puppet courses to become puppet masters. But how would smaller players get to learn puppet to a professional level if they do not go to courses and basically learn it via their browser and editor?

• Bash script 'while read' loop causes 'broken pipe' error when run with GNU Parallel

  - by Joe White

  According to the GNU Parallel mailing list this is not a GNU Parallel-specific problem. They suggested that I post my problem here. The error I'm getting is a "broken pipe" error, but I feel I should first explain the context of my problem and what causes this error. It happens when trying to use any bash script containing a 'while read' loop in GNU Parallel. I have a basic bash script like this: #!/bin/bash # linkcheck.sh while read domain do host "$domain" done Assume that I want to pipe in a large list (250mb say). cat urllist | ./linkcheck.sh Running host command on 250mb worth of URLs is rather slow. To speed things up I want to break up the input into chunks before piping it and then run multiple jobs in parallel. GNU Parallel is capable of doing this. cat urllist | parallel --pipe -j0 parallel ./linkcheck.sh {} {} is substituted by the contents of urllist line-by-line. Assume that my systems default setup is capable of running 500ish jobs per instance of parallel. To get round this limitation we can parallelize Parallel itself: cat urllist | parallel -j10 --pipe parallel -j0 ./linkcheck.sh {} This will run 5000'ish jobs. It will also, sadly, cause the error "broken pipe" (bash FAQ). Yet the script starts to work if I remove the while read loop and take input directly from whatever is fed into {} e.g., #!/bin/bash # linkchecker.sh domain="$1" host "$1" Why will it not work with a while read loop? Is it safe to just turn off the SIGPIPE signal to stop the "broken pipe" message, or will that have side effects such as data corruption? Thanks for reading.

• Mounting 2.5" SSD in Antec Atlas 550's 3.5" bay

  - by cecilkorik

  Just got some new SSDs to add to my servers, unfortunately there doesn't appear to be anywhere to actually mount them. The cases are Antec Atlas 550 mid-tower server cases. The problem is that the 3.5" bays are intended for 3.5" hard drives (obviously) not SSDs, so they are mounted from the bottom with rubber grommets to reduce vibration. There are NO side-holes in any of the 3.5" bays, all mounting has to be done from the bottom of the drive, through the thick rubber grommets, which requires special extra-long screws with large heads. Those screws will not work with the SSD, the thread is too coarse, 2.5" drives apparently use M3 screws with a finer pitch. The case's 3.5" bays have holes aligned for 2.5" drives and by moving the grommets into the appropriate holes they line up with the SSD. But that's as far as I can get. I don't have and cannot find any screws that use the finer M3 pitch that are long enough and have the wide head. I can't remove the grommets because the screw holes are much too wide without them, the entire head of the screw fits through. And again, there are no side-holes, so I can't use the mounting bracket that came with the drive nor any other 2.5"-3.5" bracket I've found. Here is a pic of what I am dealing with (note that the SSD is just resting on the case, it's not currently screwed in if that's not clear) Any ideas for safely mounting these little guys without resorting to duct tape or superglue would be very appreciated. If anyone knows where I could buy the appropriate type of M3 threaded screw or has any other ideas please help me out here.

• MS SQL Server slows down over time?

  - by Dave Holland

  Have any of you experienced the following, and have you found a solution: A large part of our website's back-end is MS SQL Server 2005. Every week or two weeks the site begins running slower - and I see queries taking longer and longer to complete in SQL. I have a query that I like to use: USE master select text,wait_time,blocking_session_id AS "Block", percent_complete, * from sys.dm_exec_requests CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 order by start_time asc Which is fairly useful... it gives a snapshot of everything that's running right at that moment against your SQL server. What's nice is that even if your CPU is pegged at 100% for some reason and Activity Monitor is refusing to load (I'm sure some of you have been there) this query still returns and you can see what query is killing your DB. When I run this, or Activity Monitor during the times that SQL has begun to slow down I don't see any specific queries causing the issue - they are ALL running slower across the board. If I restart the MS SQL Service then everything is fine, it speeds right up - for a week or two until it happens again. Nothing that I can think of has changed, but this just started a few months ago... Ideas? --Added Please note that when this database slowdown happens it doesn't matter if we are getting 100K page views an hour (busier time of day) or 10K page views an hour (slow time) the queries all take a longer time to complete than normal. The server isn't really under stress - the CPU isn't high, the disk usage doesn't seem to be out of control... it feels like index fragmentation or something of the sort but that doesn't seem to be the case. As far as pasting results of the query I pasted above I really can't do that. The Query above lists the login of the user performing the task, the entire query, etc etc.. and I'd really not like to hand out the names of my databases, tables, columns and the logins online :)... I can tell you that the queries running at that time are normal, standard queries for our site that run all the time, nothing out of the norm.

• How to list rpm packages/subpackages sorted by total size

  - by smci

  Looking for an easy way to postprocess rpm -q output so it reports the total size of all subpackages matching a regexp, e.g. see the aspell* example below. (Short of scripting it with Python/PERL/awk, which is the next step) (Motivation: I'm trying to remove a few Gb of unnecessary packages from a CentOS install, so I'm trying to track down things that are a) large b) unnecessary and c) not dependencies of anything useful like gnome. Ultimately I want to pipe the ouput through sort -n to what the space hogs are, before doing rpm -e) My reporting command looks like [1]: cat unwanted | xargs rpm -q --qf '%9.{size} %{name}\n' > unwanted.size and here's just one example where I'd like to see rpm's total for all aspell* subpackages: root# rpm -q --qf '%9.{size} %{name}\n' `rpm -qa | grep aspell` 1040974 aspell 16417158 aspell-es 4862676 aspell-sv 4334067 aspell-en 23329116 aspell-fr 13075210 aspell-de 39342410 aspell-it 8655094 aspell-ca 62267635 aspell-cs 16714477 aspell-da 17579484 aspell-el 10625591 aspell-no 60719347 aspell-pl 12907088 aspell-pt 8007946 aspell-nl 9425163 aspell-cy Three extra nice-to-have things: list the dependencies/depending packages of each group (so I can figure out the uninstall order) Also, if you could group them by package group, that would be totally neat. Human-readable size units like 'M'/'G' (like ls -h does). Can be done with regexp and rounding on the size field. Footnote: I'm surprised up2date and yum don't add this sort of intelligence. Ideally you would want to see a tree of group-package-subpackage, with rolled-up sizes. Footnote 2: I see yum erase aspell* does actually produce this summary - but not in a query command. [1] where unwanted.txt is a textfile of unnecessary packages obtained by diffing the output of: yum list installed | sed -e 's/\..*//g' > installed.txt diff --suppress-common-lines centos4_minimal.txt installed.txt | grep '>' and centos4_minimal.txt came from the Google doc given by that helpful blogger.

• MySQL is killing the server IO.

  - by OneOfOne

  I manage a fairly large/busy vBulletin forums (running on gigenet cloud), the database is ~ 10 GB (~9 milion posts, ~60 queries per second), lately MySQL have been grinding the disk like there's no tomorrow according to iotop and slowing the site.

• Internal Use Chat/Desktop Platform

  - by Malnizzle

  I did some looking, but I didn't see a SF question directly related to this. I need to find a platform for internal/LAN use only for chat and desktop sharing. We got a lot people having to get up and walk over to another person's office for simple items, and we could save a lot of time collectivity if we had a solution where we had a client app similar to gchat or AIM, where one could right click a name and request a desktop sharing session (to or from). This wouldn't be for product presentation or long training sessions, and wouldn't need more than 2 people in the session. We use GoToMeeting for this. I've looked at TeamViewer, and they got the features I want (plus a lot more features that wouldn't help) and seem more geared to large enterprise support, and it is not exactly cheap. Also looked at OCS some as well, but it seems heavy for what I am trying to do. I don't need anything relating to phone usage. If the general opinion says otherwise, I could talked back into OCS if I am wrong about weight of the product. We use GoToAssist for remote support of clients (which I am a fan of), and I don't it fits here, correct me if I am wrong. All the workstations are XP/7. Thanks!

• Solaris TCP stack tuning

  - by disserman

  We have a large web project (about 2-3k requests per second), using haproxy (http://haproxy.1wt.eu/) as a frontend and load balancer between the java application servers. The frontend (haproxy) is running on Linux but we are going to migrate it to the Solaris 10 as all our other servers are running under Solaris. After switching a traffic I see the two things: a) the web site became loading slower (5-10 seconds with images in comparison to 2-3 seconds on Linux) b) sometimes haproxy fails to perform a "lifecheck" (get a special web page and analyze http response code) due to the socket timeout. After switching traffic back to Linux everything is okay. I've tried to tune all params I found in /dev/tcp but no progress. I believe the problem is in some open socket limitations. If someone can point me to the answer, I would be greatly appreciated. p.s. haproxy is running under Xen DomU on Linux (Kernel 2.6.18, Debian 5), under zone on Solaris (10 u8). the only thing we did on Linux is increasing of ip_conntrack_max (I believe Solaris option tcp_conn_req_max_q is the equivalent).

• iptables (NAT/PAT) setup for SSH & Samba

  - by IanVaughan

  I need to access a Linux box via SSH & Samba that is hidden/connected behind another one. Setup :- A switch B C |----| |---| |----| |----| |eth0|----| |----|eth0| | | |----| |---| |eth1|----|eth1| |----| |----| Eg, SSH/Samba from A to C How does one go about this? I was thinking that it cannot be done via IP alone? Or can it? Could B say "hi on eth0, if your looking for 192.168.0.2, its here on eth1"? Is this NAT? This is a large private network, so what about if another PC has that IP?! More likely it would be PAT? A would say "hi 192.168.109.15:1234" B would say "hi on eth0, traffic for port 1234 goes on here eth1" How could that be done? And would the SSH/Samba demons see the correct packet header info and work?? IP info :- A - eth0 - 192.168.109.2 B - eth0 - 192.168.109.15 - eth1 - 192.168.0.1 C - eth1 - 192.168.0.2 A, B & C are RHEL (RedHat) But Windows computers can be connected to the switch. I configured the 192.168.0.* IPs, they are changeable. Any help?

• Network Management Cable Labeling Techniques and their alternatives [closed]

  - by Alex

  Possible Duplicate: What is the most effective solution you used to label cables? Yes i know there are a lot of howtos and already answered questions about this topic, like this one: How do you organise the cables in your racks? Currently i am searching the web for different techniques (alternatives) for labeling the cables at the server racks and/or data centers. Unfortunately i do not have any experience with labeling/documentation of network cables in a large scale. As far as I could lookup by now the current labeling techniques are coloring and a self defined print-labeling technique (numbering, text) maybe also according to a standard which are usually used. I want to know if QR, RFID (ok RFID in a data center would be stupid due to the radio frequency wouldn't it be?), Barcodes or similar (??) have already been used by some administrators or why they did not consider such techniques at all? Too complicated (with QR scanner etc..) if you are in front of the cables and want to get quick feedback for what the cable is? What alternatives are out there? Advantages/Disadvantages? Best-Practice? I would appreciate any help on this topic, thank you! Regards, Alex

• How do I host multiple independent, secured SharePoint sites (WSS 3.0) without using Active Director

  - by Kyle Noland

  I have a SharePoint site set up on one of my networks to service Active Directory users. To be clear, this is a Windows SharePoint Services 3.0 installation running on Windows Server 2003 Standard. It is not an option to upgrade the server or SharePoint version. Management would like to create several new sites, one for each of a handful of clients. These sites will be used like "dropboxes" or FTP sites so that my company can make large files available to outside contacts, and vice versa. Here are my requirements: I do not want to have to create Active Directory accounts for each external contact. If possible, I would like to store the external usernames and passwords in a database that I can write a small GUI for so that management can handle adding their own external contacts. Each client site must be sandboxed from each other and from my main company SharePoint site. I would like to keep everything running on port 80 and be able to access the sites as either clientname.mycompany.com or www.mycompany.com/clientname If anybody has ever done this I would really appreciate hearing about any lessons you learned and suggestions for how to set this up.

• How can I set up a 404 error page when people access http://ftp.mydomain.com?

  - by Tim B.

  I am a freelance videographer/developer, and part of my job involves transferring large files over FTP to production houses/television stations. While the majority of people in my industry understand the difference between FTP and HTTP, I've experienced several interactions in the past couple months of people who still open Internet Explorer and try to access http://ftp.mydomain.com, receive an error page served by HostGator, and tell me that they cannot access my FTP server. Instead of spending time delivering instructions via e-mail, I'd much prefer to serve up a custom error page in this instance that instructs them how to download and use an FTP client. I tried setting up a sub-domain in Cpanel hoping I could simply drop in an .htaccess file with the error page, but I got this error: ftp.mydomain.com domainadmin-domainexistsglobal I also tried creating a custom error page in PHP which reads the site URL and serves up the custom content only when http://ftp.mydomain.com is accessed. Unfortunately, the error page works for every subdomain except that one. I'm not entirely sure this is even technically possible, which is why I bring it to the good people of StackOverflow to help. Thanks!

• How do I stop MSYS from transforming my compiler options?

  - by Carl Norum

  Is there a way to stop MSYS/MinGW from transforming what it thinks are paths on my command lines? I have a project that's using nmake & Microsoft Visual Studio 2003 (yeecccch). I have the build system all ported and ready to go for GNU make (and tested with Cygwin). Something weird is happening to my compiler flags when I try to compile in an MSYS environment, though. Here's a simplified example: $ cl /nologo Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.6030 for 80x86 Copyright (C) Microsoft Corporation. All rights reserved. /out:nologo.exe C:/msys/1.0/nologo LINK : fatal error LNK1181: cannot open input file 'C:/msys/1.0/nologo.obj' As you can see, MSYS is transforming the /nologo compiler switch into a windows path, and then sending that to the compiler. I really don't want this to happen - in fact I'd be happy if MSYS never transformed any paths - my build system had to take care of all that when I first ported to Cygwin. Is there a way to make that happen? It does work to change the command to $ cl -nologo Which produces the expected results, but this build system is very large and very painful to update. I really don't want to have to go in and change every use of a / for a flag to a -. In particular, there may be tools that don't support the use of the - at all, and then I'll really be stuck. Thanks for any suggestions!

• Performance of Virtual machines on very low end machines

  - by TheLQ

  I am managing a few cheap servers as my user base isn't large enough to get much more powerful servers. I also don't have the money lying around to invest in a server to prepare for the larger user base. So I'm stuck with the old hardware I have. I am toying with the idea of virtualizing all the current OS's with most likely VMware vSphere Hypervisor (AKA ESXi) Xen (ESXi has too strict of an HCL, and my hardware is too old). Big reasons for doing so: Ability to upgrade and scale hardware rapidly - This is most likely what I'll be doing as I distribute services, get a bigger server, centralize (electricity bills are horrible), distribute, get a bigger server, etc... Manually doing this by reinstalling the entire OS would be a big pain Safety from me - I've made many rookie mistakes, like doing lots of risky work on a vital production server. With a VM I can just backup the state, work on my machine, test, and revert if necessary. No worries, and no OS reinstallation Safety from other factors - As I scale servers might go down, and a backup VM can instantly be started. Various other reasons. However the limiting factor here is hardware. And I mean very depressing hardware. The current server's run off of a Pentium 3 and 4, and have 512 MB and 768 MB RAM respectively (RAM can be upgraded soon however). Is the Virtualization layer small enough to run itself and a Linux OS effectively? Will performance be acceptable (50% CPU overhead for every operation isn't acceptable)? Does it leave enough RAM for the Linux OS? Is this even feasible?

• How do I host multiple independent, secured SharePoint sites (WSS 3.0) without using Active Directory on the same server?

  - by Kyle Noland

  I have a SharePoint site set up on one of my networks to service Active Directory users. To be clear, this is a Windows SharePoint Services 3.0 installation running on Windows Server 2003 Standard. It is not an option to upgrade the server or SharePoint version. Management would like to create several new sites, one for each of a handful of clients. These sites will be used like "dropboxes" or FTP sites so that my company can make large files available to outside contacts, and vice versa. Here are my requirements: I do not want to have to create Active Directory accounts for each external contact. If possible, I would like to store the external usernames and passwords in a database that I can write a small GUI for so that management can handle adding their own external contacts. Each client site must be sandboxed from each other and from my main company SharePoint site. I would like to keep everything running on port 80 and be able to access the sites as either clientname.mycompany.com or www.mycompany.com/clientname If anybody has ever done this I would really appreciate hearing about any lessons you learned and suggestions for how to set this up.

• Pushing updates to live server... FTP isn't cutting it... a better method?

  - by Jenkz

  I'm the lead developer in a team of 2. My partner has only just joined the project and despite using GIT for version control etc, we are still stuck in the dark ages when it comes to code deployment. Currently I make all site updates via FTP (this way I have control / responsibility over everything that goes live), using Filezilla. I've done this for years, but we now have some large PHP classes (300KB), and a lot of traffic. So in short, every time I upload a key class "general" for example, the site goes down until the file finishes uploading. This is only 5/6 seconds at a time, but this is increasingly unacceptable. I realise I can upload the file under a different name and then rename both files... but really there must be a better way? I've heard about rsyncing code across from another server, but I don't see how this prevents switching to the new file whilst uploading. We only have one server (for DB and Apache) but also use some cloud servers (for openx as an example).

• deploy LAMP config to new boxes with low/no effort

  - by user1444233

  I'm spending a lot of time setting up new Centos 6 instances. I use a VCS (Subversion) for most of the config files and all of the webapp source files (Github), but even with excellent package managers (like yum, npm, easy_install, etc.) it still takes time. I'd like to get to the point where I could try out a new potential web host by just signing up for an account, logging in and automatically sucking my standardised config onto the box. I know there are a set of tools that can help: Puppet Chef Vagrant and a set of services that sell solutions: [Jumpbox] http://www.jumpbox.com/ [BitNami Cloud] http://bitnami.org/cloud I don't mind investing time in learning a new tool, but as a no-budget start-up, I'm keen to keep monthly costs down. My biggest concern is that time spent on the server config is time away from the codebase, and that's where I think my team and I should be investing our energy, at least until we get funded and scale up a bit. I'd be grateful of some recommendations for which way to jump on config: stick with SSH and manual deploys, at least until you get big. bite the bullet and learn [say] puppet. You may only use it 8-10 times, but it pays to have such an easy tunable server bootstrap. don't bother, just pay the $100/month for a standard config service. It'll cost you $1000/year, but you should focus on the code. Other questions in this domain I use quite a complex stack (Drupal, Zend Server, MySQL, PHP, MongoDB, Python, django), but are there standard(ish) setups that include these or that I could build upon more quickly? Are the configs optimised for small, medium, large VPS (1GB, 4GB, 16GB)? How secure are they?

• What is optimal hardware configuration for heavy load LAMP application

  - by Piotr K.

  I need to run Linux-Apache-PHP-MySQL application (Moodle e-learning platform) for a large number of concurrent users - I am aiming 5000 users. By concurrent I mean that 5000 people should be able to work with the application at the same time. "Work" means not only do database reads but writes as well. The application is not very typical, since it is doing a lot of inserts/updates on the database, so caching techniques are not helping to much. We are using InnoDB storage engine. In addition application is not written with performance in mind. For instance one Apache thread usually occupies about 30-50 MB of RAM. I would be greatful for information what hardware is needed to build scalable configuration that is able to handle this kind of load. We are using right now two HP DLG 380 with two 4 core processors which are able to handle much lower load (typically 300-500 concurrent users). Is it reasonable to invest in this kind of boxes and build cluster using them or is it better to go with some more high-end hardware? I am particularly curious how many and how powerful servers are needed (number of processors/cores, size of RAM) what network equipment should be used (what kind of switches, network cards) any other hardware, like particular disc storage solutions, etc, that are needed Another thing is how to put together everything, that is what is the most optimal architecture. Clustering with MySQL is rather hard (people are complaining about MySQL Cluster, even here on Stackoverflow).

• Is one server on a vlan unnecessary?

  - by moomoochoo

  DETAILS I've been researching web hosting solutions in Japan. Based on this question one of the services available seems to be a VLAN. I've read about the advantages of such a system for a large organization, but there doesn't seem to be much information regarding smaller setups. I take that to mean that for one server it is likely to be unnecessary? My concern is that I don't know how many other servers are on the WAN, so regardless of how many servers I use a VLAN might still be a good idea. SERVER INFO One dedicated server would be used. It would not be virtualized. My Research so far Based on comments here, a VLAN would be useful for mitigating these problems. A user on another server could, either mistakenly or maliciously, assign one of your IP addresses to their server, resulting in a "duplicate IP" situation that would cause connectivity issues. A user on another server could poison the arp cache and potentially redirect traffic to snoop on communication intended to/from your server. (later in the discussion this point was said to be unrealistic.) QUESTION Is it worthwhile getting a vlan for one dedicated server? Will it be easier/the same/ harder to manage?

• Serving images from another hostname vs Apache overload for the rewrites

  - by luison

  We are trying to improve further the speed of some sites with older HTML in order as well to obtain better SEO results. We have now applied some minify measures, combined html, css etc. We use a small virtualized infrastructure and we've always wanted to use a light + standar http server configuration so the first one can serve images and static contents vs the other one php, rewrites, etc. We can easily do that now with a VM using the same files and conf of vhosts (bind mounts) on apache but with hardly any modules loaded. This means the light httpd will have smaller fingerprint that would allow us to serve more and quicker, have more minSpareServer running, etc. So, as browsers benefit from loading static content from different hostnames as well, we've thought about building a rewrite rule on our main server (main.com) to "redirect" all images and css *.jpg, *.gif, *.css etc to the same at say cdn.main.com thus the browser being able to have more connections. The question is, assuming we have a very complex rewrite ruleset already (we manually manipulate many old URLs for SEO) will it be worth? I mean will the additional load of main's apache to have to redirect main.com/image.jpg (I understand we'll have to do a 301) to cdn.main.com/image.jpg + then cdn.main.com having to serve it, be larger than the gain we would be archiving on the browser? Could the excess of 301s of all images on a page be penalized by google? How do large companies work this out, does the original code already include images linked from the cdn with absolute paths? EDIT Just to clarify, our concern is not to do so much with server performance or bandwith. We could obviously employ an external CDN server but we have plenty CPU and bandwith. Our concern is with how to have "old" sites with plenty semi-static HTML content benefiting from splitting connections for images and static content via apache without having to change the html to absolute paths (ie. image.jpg to cdn.main.com/image.jpg happening on the server not the code)

• Can any iSCSI NAS appliance replicate / clone a LUN to an external drive?

  - by Boden

  I would like to backup using Windows Imaging to some kind of NAS appliance. I believe this will require the NAS to support iSCSI. I would then like the appliance to support the replication of the iSCSI LUN to an external eSATA or USB disk connected directly to the appliance. I've found plenty of NAS appliances that can do iSCSI and replicate to an external drive, but none that I've found thus far can do both at once. That is, the devices can do iSCSI, but then the replication feature doesn't work. The idea here is to backup to an appliance located in a secure office far away from the server room. Offsite backups to external hard drive could be managed from the appliance. The benefits of such a setup would be: 1) very unlikely that fire or random theft would affect both server-room backup and "remote" backup appliance 2) offsite backups could be managed by multiple trusted people without granting access to server room 3) Windows imaging provides poor man's deduplication, so each backup volume can contain a decent backup history. I understand why this would be a non-trivial thing to implement, but I'm wondering if such a thing exists? Preferably a tabletop, low to medium cost device. Alternative solutions welcome. NOTE: I'm backing up very few but very large files, so file replication is not a good option.
