• APC + FPM memory fragmentation without a reason

  - by palmic

  My setup @ debian 6-testing is: nginx 1.1.8 + php 5.3.8 + php-fpm + APC 3.1.9 Because i use automatic deployment with apc_clear_cache() after deploy, my target is to set up APC to cache all my project (up to 612 php files smaller than 1MB) without files changes checking. My confs: FPM: pm.max_children = 25 pm.start_servers = 4 pm.min_spare_servers = 2 pm.max_spare_servers = 10 pm.max_requests = 500 APC: pc.enabled="1" apc.shm_segments = 1 apc.shm_size="64M" apc.num_files_hint = 640 apc.user_entries_hint = 0 apc.ttl="7200" apc.user_ttl="7200" apc.gc_ttl="600" apc.cache_by_default="1" apc.filters = "apc\.php$,apc_clear.php$" apc.canonicalize="0" apc.slam_defense="1" apc.localcache="1" apc.localcache.size="512M" apc.mmap_file_mask="/tmp/apc-php5.XXXXXX" apc.enable_cli="0" apc.max_file_size = 2M apc.write_lock="1" apc.localcache = 1 apc.localcache.size = 512 apc.report_autofilter="0" apc.include_once_override="0" apc.coredump_unmap="0" apc.stat="0" apc.stat_ctime="0" The problem is i have my APC memory fragmented into 5 pieces at 14,5MB loaded into memory which capacity is 64M. My system memory is 640MB, used about 270MB at most. The http responses lasts about 300ms - 5s. When i switch on apc.stat="1", the responses are about 50ms - 80ms which is quite good, but i cannot understand why is apc.stat="0" so much whorse. The APC diagnostic tool shows "1 Segment(s) with 64.0 MBytes (mmap memory, pthread mutex Locks locking)" in general cache information window so i hope i am right that it's mmap setup which allows tweaking APC shm onto upper values than shows system limit in /proc/sys/kernel/shmmax (my shows 33MB).

The webserver run just fine when we use the phpinfo.php test file. However as soon as I point it to my apps, nothing comes up. Check the error.log file and there's no error. Very mind boggling. I spent over 1 week trying to figure it out with no luck.. Please help?

• mysql master-master setup as a way to simply master-slave promotion

  - by Chris Go

  I'm trying to see if the following plan is viable. Goal here is to be able to do HA (uptime) and not necessarily for load -- writes are fine on one MySQL 5.5 server (with innodb) but not really possible when the database is down. Currently, I have a master-slave replication setup which works fine except it doesn't have automatic promotion (obviously). what I am planning on doing is setup master-master replication to possibly do this "automatic promotion" using Amazon Route 53 DNS Failover (Health checks). What I am trying to avoid is to NOT have to do the auto-increment trick because the "business folks" got used to the auto-incrementing PK as consecutive numbers (yeah, I know this is bad but data is from 2004). So, setup the master-master replication WITHOUT the auto-increment collision prevention bit. The primary master is db1.domain.com and secondary master is db2.domain.com In Amazon Route 53, setup DNS Failover record for db.domain.com - primary failover is db1.domain.com - with a TCP healthcheck on IP address port 3306 - secondary failover is db2.domain.com - with a TCP healthcheck on IP address port 3306 Most of the time (99%), unless tcp://db1.domain.com:3306 is dead, db1.domain.com will be served up on DNS hits to db.domain.com. In fact, hopefully this is 100%. The possible downsides of this is the loss of a primary key (collision) and I think I am OK with losing one order. We are a low data volume B2B business and can just call our client up if this occurs (like an order disappearing). Does this sound like a good plan? Then I will also run another slave replication on db1.domain.com as "master" to a slave-db1.domain.com -- not sure why, maybe for heavy SELECTs?

• Puppet Agent fails sporadically, with either timeout or "Could not find class" error

  - by smokris

  I have puppet master running on a Xen dom0, and 3 domUs syncing to it via an hourly crontab puppet agent --test. About 80% of the time, the puppet agent --test completes successfully: info: Retrieving plugin info: Caching catalog for test3 info: Applying configuration version '1333319732' notice: Finished catalog run in 5.08 seconds The other 20% of the time, it fails midway, with errors such as the following: err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class iptables for test1 at /etc/puppet/manifests/site.pp:1 on node test1 warning: Not using cache on failed catalog err: Could not retrieve catalog; skipping run or info: Retrieving plugin info: Caching catalog for test2 info: Applying configuration version '1333319732' notice: Finished catalog run in 24.73 seconds err: Could not send report: Error 500 on SERVER: Internal Server Error private method `gsub' called for WEBrick::HTTPStatus::RequestTimeout:Class WEBrick/1.3.1 (Ruby/1.8.5/2006-08-25) OpenSSL/0.9.8e-rhel5 at puppet:8140 or info: Retrieving plugin err: Could not retrieve catalog from remote server: execution expired warning: Not using cache on failed catalog err: Could not retrieve catalog; skipping run or info: Retrieving plugin info: Caching catalog for test3 info: Applying configuration version '1333319732' notice: Finished catalog run in 9.47 seconds err: Could not send report: Error 408 on SERVER: Request Timeout During this time, I've not made any changes to the Puppet configuration — it just sporadically fails. I'm running puppet-2.7.12 on CentOS, and followed the setup instructions described on http://docs.puppetlabs.com/learning/agent_master_basic.html. Any ideas about how I can troubleshoot this?

• SQL Server slow in production environment

  - by Lieven Cardoen

  I have a weird problem in a customer's production environment. I can't give any details on the infrastructure, except that SQL server runs on a virtual server. The data, log and filestream file are on another storage server (data and filestream together and log on a separate server). In our local Test environment, there's one particular query that executes with these durations: first we clear the cache 300ms (First time it takes longer, but from then on it's cached.) 20ms 15ms 17ms In the customer's production environment, the SQL Server is more powerful, these are the durations (I didn't have the rights to clear the cache. Will try this tomorrow). 2500ms 2600ms 2400ms The servers in the customer's production environment are more powerful but they do have virtual servers (we don't). What could be the cause... Not enough memory? Fragmentation? Physical storage? How would you tackle this performance problem? EDIT: Some people have asked me if the data set is equal and it is. I restored their database on our environment. It's true that this was the first thing I looked at. (@Everyone: I added the edit because it will be the first thing that many will think off).

• Building new computer, turns on, but no post

  - by addybojangles

  Pardon my ignorance here, finally decided to put together a computer and egads. I purchased a new motherboard, power supply, processor, video card and memory. ASUS M4A79XTD EVO AM3 AMD 790X ATX AMD Motherboard OCZ Fatal1ty OCZ550FTY 550W ATX12V v2.2 / EPS12V SLI Ready 80 PLUS Certified Modular Active PFC Power Supply AMD Phenom II X4 965 Black Edition Deneb 3.4GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Quad-Core Processor XFX HD-577A-ZNFC Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Dual Channel Kit Desktop Memory Model F3-12800CL9D-4GBNQ (originally had links for you guys, but I lack the rep, sorry!!) And I've got it all in the tower. I put in power supply, installed processor on motherboard, installed heatsink, put in ram, and I am using an older IDE hard disk. When I start the computer, the monitor tells me "check signal cable." As far as I can tell, the heatsink on the processor is spinning, the power supply is on (obviously), and the green LED on the motherboard is on. I originally only had the bigger output plugged in to the motherboard (what I saw in a YouTube vid as well as the mobo instructions), but after doing some research, it said plug in the other ATX power supply. Which I did. And trying to power the computer results in nothing. No beeps on startup, no post, anyone have any ideas? Your ideas and help is greatly appreciated.

• Apache Won't Restart After Compiling PHP with Postgres

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.

• How do I Setup Multiple Sites in HostGator Shared Hosting?

  - by cillosis

  I recently decided to consolidate all of my random projects into a single hosting account as it was starting to get very expensive to run each on an individual hosting plan. I purchased the HostGator Baby plan which allows hosting of multiple domains. You have to set it up with a root domain name which is fine (I used my portfolio domain name). As far as file structure, I wanted a folder for each site in /public_html so the structure looks like this: - public_html/ - myportfolio.com/ - ... my files ... - anothersite.com/ - ... my files ... - thirdsite.com/ - ... my files ... I setup add-on domains and pointed them to their respective folders which works fine. My problem is the root domain ex. myportfolio.com expects it's files to be contained at the root of /public_html rather than within it's folder I created. I setup a redirect to point requests for myportfolio.com to myportfolio.com/myportfolio.com/ which works initially except (at least in my WordPress installation) it still references it's root folder as public_html. TL;DR; What is the best way to go about setting up multiple site hosting in a shared hosting environment (i.e. I can't setup vhosts). Does anybody know of any tutorials or videos that walk through this more clearly? Thanks.

  Need some assistance in analyzing apache and php process running on linux server. Its a 8-core intel processor with 4GB ram. When the website on it runs the top displays like this. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 23459 username1 16 0 151m 27m 8388 S 11.3 0.7 0:11.71 php5 23730 username1 16 0 151m 28m 8388 S 11.3 0.7 0:03.87 php5 23458 username1 16 0 151m 28m 8388 S 3.0 0.7 0:19.20 php5 16202 mysql 15 0 459m 38m 4624 S 0.7 1.0 62:33.81 mysqld 24141 nobody 15 0 311m 5832 2304 S 0.3 0.1 0:00.03 httpd Why does the command say php5 when the website is accessed. Both apache and php was preconfigured so not sure whats done there. Tried setting up the same site and db on a different server but on it the process shows httpd always and not php5. The site uses mysql db. The problem is server load seems to go till about 5.x when the website was access by about 16users. When the free -m command was given the output shows total used free shared buffers cached Mem: 3941 3727 213 0 236 2734 -/+ buffers/cache: 756 3184 Swap: 4095 0 4095 Lots of memory seems to be in cache and free memory is less. Even when the website is not accessed that is leaving it very much idle for about 2days the free memory showed just 190. When the site is accessed the free memory seems to be go till 90mb then it increases to about 150mb. It always seems to remain just about 200mb. Is it somehow related to the server load showing 5.x. Will adding some more RAM resolve the load issue?

• Hosting a javascript api file for third party sites the way sharethis, uservoice, analytics do it.

  - by Dayson

  I'm preparing to launch a service soon which will provide third party websites a widget. The widget requires my javascript file in the website's code. Exactly the same way services like analytics, uservoice, sharethis, getclicky, etc provide you with a javascript snippet to add to your page. Therefore, my javascript file is going to be hotlinked by tons of websites which possibly receive a lot of requests too. I need advice/opinions on the following aspects: What's the right location for hosting this file? Should I use a sub-domain for it? I was thinking of something like http://api.myservice.com/js/foo.js . Remember, once websites start embedding this file, its location CANNOT change under any circumstances. Right now we can afford just one dedicated server. So I have minified my file, enabled gzip and plan to use some good cache control headers through apache. Also, in the near future when the requests pickup, I will use a http proxy like Varnish. Is this a good plan for the near future? Should I be considering a CDN in the future (since we can't afford it now)? If so how do I make sure we're prepared to migrate to it without breaking services. Pros/Cons of moving just this file to a CDN? Also, since its just one javascript file(50kb), any affordable CDN so we could consider it in the beginning itself? Any other word of advice I could use? Anything I shouldn't overlook at this stage which I would regret later? (both in terms of server + javascript ajax limitations) Thanks in advance.

• Which apache/mysql/php package is best for windows?

  - by crosenblum

  I have tried appservnetwork, was the best so far, but I haven't seen them do an update in ages, EasyPHP is just slow to load always. Wamp and Xamp, all put in their description that is not for production. I do not plan to host publicly this site or site's I am working on. But I do want a fast loading apache/mysql/php server for development purposes. I used to really like WLMP, which is Lighttpd for Windows, but that project seems unupdated or abandoned. I refuse to use IIS, but i have no desire to get into any wars over it. I run windows xp sp3 at my home pc. I will need to have a web server setup for professional work, as well as some fun websites I am working on. I just want it fast enough, so i can run it via localhost, and not take forever to load in the browser. Thank you... I plan mostly do php programming and perhaps coldfusion via this.

• How To Remove Bottleneck with Squid Caching Proxy

  - by Volomike

  I'm more of a LAMP web developer trying to help the sysop. When I joined a project, I inherited some old PHP spaghetti code. Some of that code is that it goes out to a third-party website (let's call it thirdparty.com) and pulls down content with an HTTP-GET request. Unfortunately, the way the code is designed, it needs to do this several times a minute. When we looked at the bottlenecks on the server with 'netstat -a', we saw that connections to thirdparty.com were constantly running when this content would be plenty fine to be gathered once a day. What I need to know is if the Squid Proxy Caching Server is the solution we need? I'm guessing that this might let us have it pretend to be thirdparty.com on the network. If the web server needs to query thirdparty.com, it hits Squid instead. Squid can then determine whether it needs to supply content from cache or if it needs to go to thirdparty.com for fresh content. Is this the solution we need? And second, is this easily configured and only to cache thirdparty.com requests?

• One nginx rules for lots of subdomain

  - by komase

  I have lots of subdomain in a server. Every subdomain has its own Drupal boost rules, like in below codes: server { server_name subdomain1.website.com; location / { root /var/www/html/subdomain/subdomain1.website.com; index index.php; set $boost ""; set $boost_query "_"; if ( $request_method = GET ) { set $boost G; } if ($http_cookie !~ "DRUPAL_UID") { set $boost "${boost}D"; } if ($query_string = "") { set $boost "${boost}Q"; } if ( -f $document_root/cache/normal/$host$request_uri$boost_query.html ) { set $boost "${boost}F"; } if ($boost = GDQF){ rewrite ^.*$ /cache/normal/$host/$request_uri$boost_query.html break; } if (!-e $request_filename) { rewrite ^/(.*)$ /index.php?q=$1 last; break; } } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/html/subdomain/subdomain1.website.com$fastcgi_script_name; include fastcgi_params; } } I adding all subdomain rules manually from time to time. The size of ngin.conf has become too big. So, I need one nginx rules which do: subdomain1.website.com pointing to /var/www/html/subdomain/subdomain1.website.com subdomain2.website.com pointing to /var/www/html/subdomain/subdomain2.website.com subdomain3.website.com pointing to /var/www/html/subdomain/subdomain3.website.com ...and so on (So that no more adding rules for subdomain .website.com I need in the future.)

• How often is CRL refreshed, and how to force it to be?

  - by lockstock

  I have a web service running under IIS 7 that requires an X509 client certificate. I know that the server that it rus on needs access to DigiCert.com in order to be able to get the CRL (Certificate Revocation List). There is a need to change our proxy so I am attempting to investigate the impact of doing so. I have removed the global proxy settings using the command netsh winhttp proxy refesh, and also deleted the CRL cache using the command certutil -URLcache CRL delete. However, after doing this, all calls to the web service still succeed. This suggests to me that I am missing something here. So; If the CRL cache is cleared and the server has no way of refreshing the CRL, why do web service requets not return http 403?. I have been unable to find adequate information from googling nor from my colleagues. The reason I want it to fail is that I will not be confident that the new proxy settings work until I can see it broken first, if that makes sense. I would also like to be able to force the CRL to be refeshed in order to ensure that the new proxy settings work

• Use to host email for a domain name that wasn't our primary domain name

  - by drpcken

  Exchange 2007 on an Server 2003 active directory. My primary domain (MyMainDomain.com) controller also hosts dns and dhcp. I have a secondary domain name (MySecondDomain.net) that my Exchange Server allows emails from. It wasn't a physical domain, just accepted by exchange and setup as the Active Directory user's main smtp and outgoing address. Its MX records point to MyMainDomain.com's public exchange address. I've taken MySecondDomain.net and move the mail boxes to a hosted exchange 2010 environment. MX records now point to this new exchange system and when I send and email OUTSIDE the MyMainDomain.com environment (say gmail) it works and sends to the hosted exchange setup for MySecondDomain.net. however when I send an email from a user on MyMainDomain.com, it goes to the old exchange 2007 server I am hosting internally. I have removed MySecondDomain.net from the allowed domains, removed the DNS zone for MySecondDomain.net, and cleared DNS cache. I was convinced it was my internal dns server but I've cleared the DNS cache. Is there something I'm missing somewhere in exchange 2007? Or is it my domain controller/dns? Sorry if this is confusing. Thank you!

• managing a high traffic media sharing website

  - by Jordan Westerman

  i'm in the process of developing a website that i predict will generate a lot of traffic. the site will be similar to many other sites offering free media streaming: mp3's. we are going to start with a pretty minimal amount of media to share, but the basic idea is that artists will set up a profile page with music they have made available for consumers to visit the page and listen to the music. we are starting with just a handful of artists, but i think that this project will generate more and more artist pages. eventually i'd like to set it up so consumers can create personalized playlists. how can i best prepare server space and bandwidth capabilities? i have a small team of web designers and programmers working on the site, as i am pretty illiterate when it comes to site management. as the ring leader of this organization, i am more or less looking for financial requirements and monthly burn rate estimates. i don't have a ton of capitol to start with, putting together a business plan, but i am seeking investments. i have a game plan to grow fast enough to be successful, and slow enough to manage the financial growth requirements. any questions i may have failed to ask myself? is it realistic to start this project on a shared server, and upgrade? any financial advice you think i can use? i really appreciate any advice given, as this is my first business venture. thank you all in advance.

• PostgreSQL lots of large Arrays and Writes

  - by strife911

  Hi, I am running a python program that spawns 8 threads and as each thread launch its own postmaster process via psycopg2. This is to maximize the use of my CPU-cores (8). Each thread call a series of SQL Functions. Most of these functions go through many thousands of rows each associated to a large FLOAT8[] Array (250-300) values by using unnest() and multiplying each FLOAT8 by an another FLOAT8 associated to each row. This Array approach minimized the size of the Indexes and the Tables. The Function ends with an Insert into another Table of a row of the same form (pk INT4, array FLOAT8[]). Some SQL Functions called by python will Update a row of these kind of Tables (with large Arrays). Now I currently have configured PostgreSQL to use most of the memory for cache (effective_cache_size of 57 GB I think) and only a small amount of it for shared memory (1GB I think). First, I was wondering what the difference between Cache and Shared memory was in regards to PostgreSQL (and my application). What I have noticed is that only about 20-40% of my total CPU processing power is used during the most Read intensive parts of the application (Select unnest(array) etc). So secondly, I was wondering what I could do to improve this so that 100% of the CPU is used. Based on my observations, it does not seem to have anything to do with python or its GIL. Thanks

• Pentium 4 Willamette vs. Faster Celeron Northwood [closed]

  - by Synetech inc.

  Which is the preferable of the following two processors? Intel® Pentium® 4 Processor 1.70 GHz, 256K Cache, 400 MHz FSB Willamette Intel® Celeron® Processor 2.40 GHz, 128K Cache, 400 MHz FSB Northwood Details: A few months ago my motherboard died, so I bought a used computer that had a 2.4GHz Celeron. My old system had a 1.7GHz Pentium 4, so now I’m trying to decide which CPU to use. Obviously a P4 is preferable over a Celeron, but the Celeron is (significantly?) faster than the P4. I’m wondering if the faster Celeron might be better for certain tasks (ie, stronger but dumber is better at some things than smarter but weaker). I tried Googling for some reviews and comparisons for graphs to get a clear depiction of which is better overall, but found nothing that helped. (I did manage to find one page that indicates (apparently by poll, not benchmark) that the Celeron is better.) So which CPU should I use? Does anyone know of some graphs that I can use to compare the two? The system is a general-purpose machine for word-processing, Internet, and casual games (not Crysis, but not Solitaire either). It will be running Windows XP. The board is a 478 with 400MHz FSB.

• Different nginx rules based on referrer

  I'm using WordPress with WP Super Cache. I want visitors who come from Google (That inlcudes all country specific referrers like google.co.in, google.co.uk and etc.) to see uncached contents. There are my nginx rules which are not working the way I want: server { server_name website.com; location / { root /var/www/html/website.com; index index.php; if ($http_referer ~* (www.google.com|www.google.co) ) { rewrite . /index.php break; } if (-f $request_filename) { break; } set $supercache_file ''; set $supercache_uri $request_uri; if ($request_method = POST) { set $supercache_uri ''; } if ($query_string) { set $supercache_uri ''; } if ($http_cookie ~* "comment_author_|wordpress|wp-postpass_" ) { set $supercache_uri ''; } if ($supercache_uri ~ ^(.+)$) { set $supercache_file /wp-content/cache/supercache/$http_host/$1index.html; } if (-f $document_root$supercache_file) { rewrite ^(.*)$ $supercache_file break; } if (!-e $request_filename) { rewrite . /index.php last; } } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/html/website.com$fastcgi_script_name; include fastcgi_params; } } What should I do to achieve my goal?
