• Ubuntu root privs installation issue

  - by Pam

  I am a fairly new Ubuntu user (and Linux user, for that matter) and I just downloaded a program whose installer was a .sh file. Not thinking, I copied the installer to an /opt subdirectory, thinking that I was going to install the application there: sudo cp ~/Downloads/fooInstaller.sh /opt/someDir I can't remember, but I either had to use sudo because /opt required it, or I just used it without thinking, but in any case, I prefixed with sudo. Once in /opt/someDir, I executed the installer again, using sudo: sudo sh fooInstaller.sh The terminal went crazy, and a few seconds later, a graphical install wizard popped up that guided me through the rest of the process. At the end of the wizard I was prompted to launch the program, and I did, and everything was great. Until... I closed the program, and attempted to add it to my Ubuntu "panel" (the icon panel at the top of the screen). The program was installed to /usr/local/foo/theProgram, and so I specified that URL as the command in the custom app launcher. When I open the program through the panel/launcher (at the top of the screen), the program doesn't load or operate correctly. I get a lot of error messages complaining about being denied permissions. I'm assuming that this is a "superuser/installation/privs" issue, and not a problem with the application (hence this post at superuser.com instead of the application's forums), because when I launch the program from the terminal with sudo, it opens and executes perfectly fine, just like it did the first time around after the install wizard finished. I realize I'm probably going to have to uninstall the program completely, and re-install it differently. Finally, my question: After uninstalling, can I avoid all these issue by just running the installer (sh fooInstaller.sh) right out of my Downloads directory, sans the sudo prefix? If not, how do I get the program to install without root privs so that I can add it to my panel/launcher and get it executing correctly? Sorry for the long post but I didn't want to omit any details because, as I'm sure you can tell, I'm not really sure I know what I'm doing. Thanks for any help here!

• InstallShield or Windows installer corrupted

  - by Bobby S

  Just recently I've been unable to install any software on my Windows 7 machine. Anything that uses InstallShield or the Windows installer will just hang or give a weird error. I noticed there will be many duplicate isbew64.exe processes (like 25) that launch and then just sit there or else a lot of msiexec.exe *32 processes, depending on what I'm trying to install. One piece of software specifically is the Logitech Harmony software. It gives me an *is_string_not_defined* error, saying c:\program files (x86)\:\ the filename, directory name, or volume label syntax is incorrect. The other thing I was trying to install was Battlefield: Bad Company 2, and that just hangs as well, and then just leaves all the Windows installer processes running in the background after I quit the install process. Very odd. I've checked well and googled these issues, it doesn't appear to be any sort of malware issue. I feel like it's related to some kind of corrupted installer application. I've rebooted, deleted the InstallShield folder in program files/common files as some places online suggested but to no avail. I have no idea what to do, any ideas?

• PostgreSQL 8.4 - Tablespace Optimization

  - by FloE

  I'm currently running a PostgreSQL Database with about 1.5 billion rows / 500 GB of data (including indices). There are several schemata: on for the (read only, irregular changes / updates) 'core-model' and one for every user (about 20 persons). The users can access the core and store data in their own schema, so everything is located in one database. The server runs with CentOS and PostgreSQL 8.4 and is used for scientific studies, exploration etc and is running quite well. These days an upgrade of the DB storage hard disks arrive - all with the same performance as the old ones. I'm looking for the best way to distribute the data on these disks. It would be possible to separate frequently used objects (the core-data) from the user schemata, but I'm not sure if this is really worth the effort. It seems to be a much better idea to move the WAL files (pg_xlog directory) to its own partition. http://www.postgresql.org/docs/8.4/static/wal-internals.html What are your opinions? Are there any tablespace- or partitioning-related performance documentations / benchmarks?

• apache2: ssl_error_rx_record_too_long when visiting port 80?

  - by John

  Hi, I have an Ubuntu 10 x64 server edition machine. I got a second IP and configured /etc/network/interfaces like so (actual IPs and gateways removed): auto lo iface lo inet loopback #iface eth0 inet dhcp auto eth0 auto eth0:0 iface eth0 inet static address [ my first IP ] netmask 255.255.255.0 gateway [ my first gateway ] iface eth0:0 inet static address [ my second IP ] netmask 255.255.255.0 gateway [ my second gateway ] /etc/apache2/ports.conf: Listen 80 NameVirtualHost [ my first IP ]:80 NameVirtualHost [ my second IP ]:80 <IfModule mod_ssl.c> # If you add NameVirtualHost *:443 here, you will also have to change # the VirtualHost statement in /etc/apache2/sites-available/default-ssl # to <VirtualHost *:443> # Server Name Indication for SSL named virtual hosts is currently not # supported by MSIE on Windows XP. Listen 443 NameVirtualHost [ my first IP - some site is running SSL successfully using it ]:443 </IfModule> <IfModule mod_gnutls.c> Listen 443 </IfModule> /etc/apache2/sites-enabled/mysite.conf: <VirtualHost [my second IP ]:80> ServerName mysite.com Include /var/www/mysite.com/djangoproject/apache/django.conf </VirtualHost> Then when visiting http[mysite].com:80 or http[mysite].com (:// removed because serverfault doesn't allow me to post hyperlinks), I get: An error occurred during a connection to [mysite].com. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long) My guess is that the configuration file is not being picked up, and apache is therefore looking for the default-ssl file, which is not in conf-enabled. If I were to configure that file properly, it seems I would successfully connect to whatever default directory is specified in the default-ssl file. But I want to connect to my website. Any ideas? Thanks in advance!

• Script errors when run by launchd at startup, but not when run in Terminal

  - by Mechcozmo

  Hello. I'm attempting to create a RAM disk that loads the previous contents when the system starts up, and every six hours writes the contents to a disk image. Currently, when you run the script from the terminal ("sudo bash LogToRAM.sh") everything works fine. But when run from launchd during startup, it doesn't work. Here's the lines from the log; the first line just gives some idea as to where in the boot process we are: SecurityAgent[202] Showing Login Window com.mechcozmo.LogToRAM[51] + /Developer/usr/bin/SetFile -a V /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] ERROR: File Not Found. (-43) on file: /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] + /usr/sbin/asr -source '/Library/Application Support/LogToRAM/RAMdisk_store.dmg' -target /Volumes/LogfileRAMdisk/ -noverify Here is the script and plist file in question. Note that 'set -vx' is up at the top of the script; it give a lot of information about what is happening in the script. My current theory is that the /Volumes directory does not exist at this stage of the boot process, but that seems unlikely to be honest.

• Sharepoint Workflow "Failed on Start" only when powershell import script is called from task scheduler

  - by Matt Keller

  I created a simple PowerShell script that takes an XML file in a local directory on our sharepoint server and imports it into a specific SharePoint form library. (Content management enabled library if that makes any difference) This script works flawlessly if i run it from the PowerShell command line manually. I call it like such: ".\script_name.ps1". It completes without error and the item is imported into the form library successfully. The workflow begins on the item and everything is happy dandy. However, i run into issues when i setup a scheduled task using Windows Server 2008 R2's task manager. The task runs the script without error and it does actually import the XML into the form library. I looks perfectly normal just as if i had run the script manually. However, after about 10 or 20 minutes the workflow status for that item changes from "In progress" to "Failed on Start (Retrying)". The scheduled task in question is a basic task and has only one action. (Start a program) The "program/script" box is set to "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" and the "Add arguments" box is set to the path of the actual ps1 script. (C:\scripts\sharepoint_import.ps1) I've tried running the task as various users. I've also tried with and without the "Run with highest privileges" check box. Nothing seems to work. For reference, here is the script i am using to import items into the form library.

• how to automatically mount ~/Private using ecryptfs when logging in via ssh pubkey

  - by andreash

  Raionale: I want to be able to automatically make backups to a remote machine, which will be encrypted with ecryptfs. The title says it all: I set up ecryptfs-utils on my Debian Squeeze box, and set up one user to use it via ecryptfs-setup-private. When I log in via SSH using password authentication, the ~/Private directory automatically gets mounted. How can I achieve that ~/Private also automatically gets mounted when logging in via SSH using public key authentication? Obviously, the best solution would be if ecryptfs could somehow 'use' the SSH public key to en/decrypt the data (I know that then using the user's password would not be able to en/decrypt the data any more; this would be acceptable). Probably, this will not work. So perhaps somehow call ecryptfs-mount-private via ssh before logging in via public key? Probably, then I would need to somehow pipe the passphrase through the SSH connection, right? So I would need to store it on the source machine's file system. Not nice either. Any other ideas?

• Passenger not booting Rails App

  - by firecall

  I'm at the end of ability, so time to ask for help. My hosting company are moving me to a new server. I've got my own VPS. It's a fresh CentOS 5 install with Plesk 9.5.2 Essentially Passenger just doesnt seem to be booting the Rails app. It's like it doesnt see it's a Rails app to be booted. I've got Rails 3.0 install with Ruby 1.9.2 built from source. I can run Bundle Install and that works. I've currently got Passenger 3 RC1 installed as per here, but have tried v2 as well. My conf/vhost.conf file looks like this: DocumentRoot /var/www/vhosts/foosite.com.au/httpdocs/public/ RackEnv development #Options Indexes I've got a /etc/httpd/conf.d/passenger.conf file which looks like this: LoadModule passenger_module /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.0.pre4/ext/apache2/mod_passenger.so PassengerRoot /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.0.pre4 PassengerRuby /usr/local/bin/ruby PassengerLogLevel 2 and all I get is a 403 forbidden or the directory listing if I enable Indexes. I dont know what else to do! Yikes. There's nothing in the Apache error log that I can see. The new server admin isnt much help as I think he's a bit junior and says he doesnt know about Rails... sigh :/ I'm a programmer and server admin isnt my bag :(

• Gerrit ssh key setup on windows server

  - by hotpotato

  I am attempting to configure google's 'Gerrit' code review web app on a Windows server 2008 virtual machine on our internal network. We are using Apache Tomcat (6.0.36) to host the web app and have deployed the gerrit.war to tomcats webapp folder, setup the context.xml, web.xml etc for the web app correctly i believe. However when i startup Tomcat using the $CATALINA_HOME/bin/startup.bat i get the following message in the tomcat logs: *Dec 07, 2012 1:03:54 PM org.apache.catalina.core.StandardContext listenerStart SEVERE: Exception sending context initialized event to listener instance of class com.google.gerrit.httpd.WebAppInitializer com.google.inject.CreationException: Guice creation errors:* 1) No SSH keys under C:\Gerrit\config\etc while locating com.google.gerrit.sshd.HostKeyProvider at com.google.gerrit.sshd.SshModule.configure(SshModule.java:90) I have created a is_rsa.pub SSH key and placed it in the specified directory to no avail. I have been googling this for about a week now and can't seem to find any information about the file or format it is expecting... documentation on setting gerrit up on windows seems hard to come by! Can anyone provide useful information about how to correctly configure a host SSH key in this context?

• CIFS mounted drive setting "stick-bit" on all files, cannot change permissions or modify files

  - by mattmcmanus

  I have a folder mounted on an Ubuntu 8.10 sever through cifs that I simply cannot change the permissions on once mounted. Here is a breakdown of what's going on: All files within the mounted folder automatically have their permissions set to -rwxrwSrwx regardless of whether the file is create on the windows server or on the linux machine. I have the same directory mounted on two other linux servers (both running 9.10 instead of 8.10) with no problems at all. They all are using the same fstab options and the same credentials. //server/folder /media/backups cifs credentials=/etc/samba/.arcadia_cred,noexec,noserverino 0 0 I've I run a chmod command a million different ways, all of which report successfully changing the permissions. However it doesn't. The issue began after I updated from 8.04 to 8.10 Any idea why this may be happening on one machine? Since it started after an upgrade I'm not sure what is the bes thing to do. Any help you could give would great! None of my automated backup scripts are working because of this!

• IIS Windows Authentication not working in Internet Explorer via host name; works via IP

  - by jkohlhepp

  I'm trying to get a new Windows Server 2003 box working to host an ASP.NET application that uses Windows Authentication. Here's some info: IIS Anonymous Access is diabled IIS Integrated Windows Authentication is enabled I've tried it with and without Digest Authentication and it is the same result Both my machine and the server are in same active directory domain on the same intranet I'm using IE 6 My symptoms: In Firefox, via either IP or host name, a login box pops up, and if I enter my NT credentials, it works. In IE, via the server IP address, it works perfectly with no login box. In IE, via the server host name, it pops up a login box but even if I put in the correct credentials, it just pops up the box again. This is the problem. Why won't windows auth work in IE via host name but it will via IP address? Edit: Here's something else interesting. If I go into my Internet Explorer advanced settings and disable Windows Authentication, it seems to work just fine. And by work I mean that my test .NET app sees my NT ID as the current user.

  Hi All: I've just run into an issue with my exchange OWA. It returns a blank page with the url string https://www.xxxxxxxx/&reason=0. Nothing in the logs gives me any good reasons.

• Bootable GRUB partition

  - by MA1

  I have a customized live fedora 12 USB which is working fine. What i want to do is to make a partition of my hard disk bootable so that my customized fedora can be run from hard disk. To accomplish this i did the following steps: Created a primary partition(/dev/sda2) and format it as ext3 and set it as active. Copy all the files in the live usb to /dev/sda2. Following are the live usb contents(all directories): a. boot b. EFI c. LiveOS d. syslinux Then i installed the GRUB in boot/grub Created the grub.conf in boot/grub Following are the contents of each directory in the USB: syslinux/ boot.cat isolinux.bin splash.jpg vesamenu.c32 initrd0.img ldlinux.sys syslinux.cfg vmlinuz0 LiveOS/ livecd-iso-to-disk osmin.img squashfs.img EFI/ boot/ boot.conf grub.conf boot.efi bootia32.conf bootia32.efi splash.jpg splash.xpm.gz vesamenu.c32 initrd0.img isolinux.bin isolinux.cfg vmlinuz0 boot/grub/ core GRUB files grub.conf olpc.fth Following are contents of grub.conf default=0 splashimage=/EFI/boot/splash.xpm.gz timeout 2 hiddenmenu title funLinux kernel /EFI/boot/vmlinuz0 root=live:LABEL=myFun rootfstype=auto ro liveimg quiet ssb.blacklist=1 selinux=0 vga=normal nomodeset rhgb initrd /EFI/boot/initrd0.img Now when i try to boot from the hard disk it shows the grub menu and fedora starting to load but during loading it said No root device found Boot has failed, sleeping forever So, where is the problem? what i am doing wrong?

• Virtualized Screen Resolution

  - by Jim R

  I have a 64 bit Ubuntu 9.10 workstation with two virtualized guest OSes using KVM/QEMU. Also both 64-bit. One is Fedora 12 the other is beta of Ubuntu 10.04. The problem is that I would like to use a larger size display that is configured by default. Both guest OSes have a maximum screen resolution of 1024x768. I would like to increase this to something like 1280x900 or 1440x900. The resolution of the host system is 1920x1080. This configuration appears to be a result of the installation detecting the resolution being reported by the virtual screen during installation. The only information I have found on the subject suggests modifying the xorg.conf file in the /etc/X11 directory. Neither guest system has this file. I tried creating one by hand in the Fedora system and managed to render it completely unusable. Not a big deal as this is recently installed and can be reinstalled easily. Is what I want to do possible? If so, how do I accomplish it?

• SuPHP custom php.ini doesn't get read

  - by Mathieu Dumoulin

  Took me about 4 hours to get a FastCGI + SuPHP running off Ubuntu 11.10 and i'm now happy that it works mighty fine except for ONE big problem. Custom php.ini's don't seem to load. I tried changing some options and then firing off a phpinfo() and nothing changes in the phpinfo() which leads me to think that there is definitely a problem with the loading of the configuration file. <IfModule mod_suphp.c> AddHandler x-httpd-php .php <Location /> SuPHP_AddHandler x-httpd-php </Location> suPHP_ConfigPath /home/mdumoulin/Documents/tests/tests suPHP_Engine on </IfModule> As you can see, i took great care in making sure i wasn't referencing the php.ini file itself but the directory of the vhost. In the php.ini located in "/home/mdumoulin/Documents/tests/tests/php.ini", you can find: [PHP] error_reporting = E_ALL & ~E_DEPRECATED & ~E_NOTICE display_errors = Off And the log in /var/log/suphp/suphp.log doesn't contain anything relevant, (only old errors that occured before this post while i was testing suphp... So i'm stumped there, dunno what more i can do! Anyone got an idea? EDIT: FINALY, got time to work on this, i disabled FCGI and only enabled SuPHP but after restarting i still see "Server API: CGI/FastCGI". Is this what i should be getting or not? I believe that it's normal i get CGI since SUPHP works with a CGI... But i'm not too sure anymore...

• Port forwarding on D-Link DIR-615 super-slow, useless

  - by Jaroslav Záruba

  Hello I have replaced my old router with DIR-615 from D-Link, and now the port forwarding is so slow it makes the router practically useless for requests coming from outside of my network. Accessing the router itself (admin UI) from outside is without any issues, no delay whatsoever. But when I try to access a service residing on any of the computers in my network from outside the requests take minutes and minutes. (E.g. I can see source of my GWT-app main page, but loading additional CSS and JS files takes years.) If anyone could recommend any further diagnostics I should do to figure out what is happening it would be great. Few notes: happens with more services (web-app on Tomcat, viewing directory index via Apache) it does not make a difference whether the service is hosted on wired or wireless PC accessing the service on a localhost works fine, as does any 'inner' communication turning off firewall on target PC does not make difference either (makes sense) when I replace this router with the old one (both 192.168.1.1) everything works fine I see nothing suspicious in the router's log I believe I have the latest firmware (4.11) DIR-615 sucks, it already died once completely Regards Jarda Z.

• Robocopy failure with Windows Server 2008 Scheduled Task

  - by CC

  So I have a batch script for robocopy. Running this from the command line does exactly what I want. robocopy "D:\SQL Backup" \\server1\Backup$\daily /mir /s /copyall /log:\\lmcrfs4g\NavBackup$\robocopyLog.txt /np Then I create a Scheduled Task in Windows Server 2008. If I set up the task to use my Domain Admin account, great. But I'm trying to get it to run as a separate domain account for Scheduled Tasks. If I use that account, folders get created, but files aren't copied. I get the following error: 2011/02/17 15:41:48 ERROR 1307 (0x0000051B) Copying NTFS Security to Destination Directory D:\SQL Backup\folder\ This security ID may not be assigned as the owner of this object. I've verified my domain\Scheduled Tasks account has Full Control NTFS permissions on both the source and destination, and the Full Control Sharing on my hidden \server1\backup$ share. Just for giggles, I've tried adding the domain account to the local Administrators group on both servers. This works fine, but that seems like a lot of privileges just to copy files. Any ideas on what I'm missing?

• django : Serving static files through nginx

  - by PlanetUnknown

  I'm using apache+mod_wsgi for django. And all css/js/images are served through nginx. For some odd, reason when others/friends/colleagues try accessing the site, jquery/css is not getting loaded for them, hence the page looks jumbled up. My html files use code like this - <link rel="stylesheet" type="text/css" href="http://x.x.x.x:8000/css/custom.css"/> <script type="text/javascript" src="http://1x.x.x.x:8000/js/custom.js"></script> My nginx configuration in sites-available is like this - server { listen 8000; server_name localhost; access_log /var/log/nginx/aa8000.access.log; error_log /var/log/nginx/aa8000.error.log; location / { index index.html index.htm; } location /static/ { autoindex on; root /opt/aa/webroot/; } } There is a directory /opt/aa/webroot/static/ which have corresponding css & js directories. The odd thing is that the pages show fine when I access them. I have cleared my cache/etc, but the page loads fine for me, from various browsers. Also, I don't see any 404 any error in the nginx log files. Actually the logs for nginx are not getting refreshed at all. I restarted the nginx server using root, is that incorrect ? There is a user www-data defined in the nginx configuration file. Any pointers would be great.

• CentOS - mdadm raid1 drive won't mount to default location

  - by danny

  I'm running CentOS 5.5, the system, boot, swap, etc. is all on /dev/sda and I have two identical single-partition drives /dev/sdb1 /dev/sdc1 that are configured in RAID1 (using mdadm). It was working fine (configured to mount to /mnt/data in the fstab file) and I recently let yum install a couple of automatic updates without paying attention to what they were, and now it doesn't work. Raid is working fine (dmesg shows it gets loaded correctly). mdstat shows: # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdc1[1] sdb1[0] XXXX blocks [2/2] [UU] unused devices: <none> Additionally, I can mount it anywhere other than its default directory (i.e. the following works, and I can read data off the drives). # mount /dev/md0 /mnt/data2 EXT3-fs warning: mounting fs with errors, running e2fsck is recommended But when I run the following I get: # mount -a mount: /dev/sdb1 already mounted or /mnt/data busy It says nothing is mounted when I try to umount /dev/sdb1 or umount /mnt/data, so I assume it's the second of those errors. However, lsof | grep mnt shows nothing. The weird thing is that I can save files in /mnt/data. So something is obviously mounted there, but when I try to umount it I get the error that nothing is mounted. /etc/mtab doesn't mention any of the partitions or files I am trying to work with, and fstab just has that one line I mentioned above that is supposed to mount my raid partition. Again, it was all working fine until I On Google I've found a few things about dmraid interfering with mdadm after an update, but I yum remove'd dmraid and rebooted and it didn't help. I'm really confused and need to get this working to get on with my work!

Before I added my Virtualenv's pythonpath to my configuration file, I was getting an ImportError for Flask. I solved this though, I believe (I'm not receiving errors about it anymore) and here is my complete configuration file: uwsgi: #socket: /tmp/uwsgi.sock socket: 127.0.0.1:3031 daemonize: /var/log/uwsgi.log pidfile: /var/run/uwsgi.pid master: true vacuum: true #wsgi-file: /var/www/coefficient/coefficient.py wsgi-file: /var/www/coefficient/flask.py processes: 1 virtualenv: /opt/python-env/coefficient/ pythonpath: /opt/python-env/coefficient/lib/python2.6/site-packages This is how I start uWSGI, from an rc script: /opt/uwsgi/uwsgi --yaml /etc/uwsgi/conf.yaml --uid uwsgi And if I try to view the Flask program in a browser, I get this: **uWSGI Error** Python application not found Any help is appreciated.

• Firefox 29 - how do I delete history entries visited fewer than x times

  - by lousyuser

  Context: I've been using my Firefox profile for a couple of years now. My history file has become huge, naturally. I got Firefox Sync set up between my main desktop PC and my laptop. HW configs: PC: i5-3450, 8 GB DDR3 RAM, Crucial M4 128 GB SSD laptop: Pentium SU4100, 4 GB DDR3 RAM, WD 5400 rpm HDD Accessing history entries when typing into the Awesome Bar on my desktop takes quite a long time despite the decent config, the laptop is even slower. The experience is quite unresponsive. I figured if I cleared the history up a little bit, I might avoid creating a new profile to speed things up. The question itself: to illustrate: Is there a way to delete all history entries that have been visited fewer than x (let's say 5) times and at the same time the recent visit is fewer than y (let's say 120) days old? afaik the history file is some kind of SQL database, but I'm not really sure how the data is saved, if there's a "safe way" to edit it and what the query to do what I need would look like. Thanks in advance for any help. I kept browsing through previous SuperUser questions to see if I could find relevant information. "In my Firefox profile directory, there is a filed named places.sqlite. Opening it with sqlite reveals (amongst others) the tables moz_places and moz_historyvisits. It seems that moz_historyvisits uses the primary of moz_places to refer to the URLs." As I'm unfamiliar with databases, I don't really understand the way the two tables mentioned in the quote are related. screenshot of a part of the tables I've noticed the visit_count is in a standard format, making it easy to work with. The last_visit_date looks encrypted to my naked eye, but I can't see in which way. Hope that helps, I'm at my wits' end.

• BASH Wildcard Expansion

  - by Aaron Copley

  I'm not really sure how to phrase this, and maybe that's why I can't find any thing, but I want to reuse the values enumerated by a wildcard in a command. Is this possible? Scenario: $ ls /dir 1 2 3 Contents of /dir are directories 1, 2, and 3. $ cp /dir/*/file . Results in file being copied from /dir/1 /dir/2 and /dir/3 to here. What I would like to do is copy the files to a new destination name based on the wildcard expansion. $ cp /dir/*/file ???-file Would result in /dir/*/file being copied to 1-file, 2-file, and 3-file. What I can't figured out is the ??? portion to tell BASH I want to use the wildcard expanded values. Using the wildcard in the target nets a cp error: cp: target `*-file' is not a directory. Is there something else in bash that can be used here? The find command has {} to use with -exec which is similar to what I am looking for above.

• Incorrect deployment of WSGI app to AWS using Elastic Beanstalk

  - by Dzmitry Zhaleznichenka

  cross-link to AWS forums I have developed a simple Python web service using WSGI and would like to deploy it to AWS cloud using Elastic Beanstalk. My problem is I cannot make all the options I specify in Elastic Beanstalk configuration to be correctly configured in the cloud. For deployment, I use Elastic Beanstalk CLI utility. I have run eb init command and set up the required parameters. After this, a directory named .elasticbeanstalk was created in my source tree. It has two config files that are used for deployment, namely config and optionsettings. The latter one among the other options contains the WSGI configuration that has to update /etc/httpd/conf.d/wsgi.conf at the instances. After some of my adjustments the file has the following settings: [aws:elasticbeanstalk:application:environment] DJANGO_SETTINGS_MODULE = PARAM1 = PARAM2 = PARAM4 = PARAM3 = PARAM5 = [aws:elasticbeanstalk:container:python] WSGIPath = handler.py NumProcesses = 2 StaticFiles = /static= NumThreads = 10 [aws:elasticbeanstalk:container:python:staticfiles] /static = static/ [aws:elasticbeanstalk:hostmanager] LogPublicationControl = false [aws:autoscaling:launchconfiguration] InstanceType = t1.micro EC2KeyName = zmicier-aws [aws:elasticbeanstalk:application] Application Healthcheck URL = [aws:autoscaling:asg] MaxSize = 10 MinSize = 1 Custom Availability Zones = [aws:elasticbeanstalk:monitoring] Automatically Terminate Unhealthy Instances = true [aws:elasticbeanstalk:sns:topics] Notification Endpoint = Notification Protocol = email It turns out that not all of these options are considered when I start the environment or update it. Thus, when I update NumThreads or NumProcesses, the respective parameters get changed in wsgi.conf as expected. But whatever I write to the WSGIPath and StaticFiles parameters, I'm not able to automatically change the respective values of wsgi.conf, they remain Alias /static /opt/python/current/app/ WSGIScriptAlias / /opt/python/current/app/application.py which drives me nuts. Moreover, when I deploy my application using git aws.push and having the following contents of .ebextensions/python.config file, neither of options I specify in it affects the deployment. option_settings: - namespace: aws:elasticbeanstalk:container:python option_name: WSGIPath value: mysite/wsgi.py - namespace: aws:elasticbeanstalk:container:python option_name: NumProcesses value: 5 - namespace: aws:elasticbeanstalk:container:python option_name: NumThreads value: 25 - namespace: aws:elasticbeanstalk:container:python:staticfiles option_name: /static/ value: app/static/ I wonder what I should do to force AWS use all the parameters I specify in the configuration, namely the WSGI Path and path to my static data.

• Deploying concrete5 on nginx

  - by Nithin

  I have a concrete5 site that works 'out of the box' in apache server. However I am having a lot of trouble running it in nginx. The following is the nginx configuration i am using: server { root /home/test/public; index index.php; access_log /home/test/logs/access.log; error_log /home/test/logs/error.log; location / { # First attempt to serve request as file, then # as directory, then fall back to index.html try_files $uri $uri/ index.php; # Uncomment to enable naxsi on this location # include /etc/nginx/naxsi.rules } # pass the PHP scripts to FastCGI server listening on unix socket # location ~ \.php($|/) { fastcgi_pass unix:/tmp/phpfpm.sock; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_path_info; include fastcgi_params; } location ~ /\.ht { deny all; } } I am able to get the homepage but am having problem with the inner pages. The inner pages display an "Access denied". Possibly the rewrite is not working, in effect I think its querying and trying to execute php files directly instead of going through the concrete dispatcher. I am totally lost here. Thank you for your help, in advance.
