I was receiving a 500 internal server error on one of my CPanel sites earlier tonight but the apache error logs in CPanel admin for that user showed nothing. Instead, I had to locate the global apache error logs. This information may help others so I’ve listed some of the most useful CPanel/WHM log file locations below:

Apache Logs

General Error and Auditing Logs:
Location : /usr/local/apache/logs/error_log
Description : All exceptions caught by httpd along with standard error output from CGI applications are logged here..
The first place you should look when httpd crashes or you incur errors when accessing website.

Domain Access Logs:
Location : /usr/local/apache/domlogs/domain.com
Description : General access log file for each domain configured with cPanel.

Apache Access Logs:
Location : /usr/local/apache/logs/access_log
Description : Complete web server access log records all requests processed by the server.

MySQL Logs

MySQL General Information and Errors:
Location : /var/lib/mysql/$(hostname).err
Description : This path could vary, but is generally located in /var/lib/mysql. Could also be located at /var/log/mysqld.log

For more log file locations, there are some great forum posts here and here.

I’ve was playing with EasyApache in a WHM install recently and after the upgrade I came across a strange error:

SoftException in Application.cpp:357: UID of script "/home/mysite/public_html/index.php" is smaller than min_uid
Premature end of script headers: index.php

Turns out this error is caused by apache being unable to read files added by root to a users public_html folder. A simple fix for this problem is to

chown -R mysite:mysite /home/mysite/public_html

Thanks to user ronniev of eukhost forums for his solution here.

One of my favourite plugins for GEdit2 was tabswitch. It made GEdit more consistant with browsers by allowing it to switch tabs with CTRL+Tab instead of CTRL+PgUp/Down. Ubuntu 11.10 comes with Gedit 3 and the plugin no longer worked – so I rewrote it!

This plugin will let you use CTRL+Tab to switch between tabs in GEdit 3. You can download a working implementation here.

Install it by copying the files into ~/.local/share/gedit/plugins directory (which doesn’t exist by default) or /usr/lib/gedit/plugins if you want it to work for all users. Remember to enable the plugin in Edit – Preferences – Plugins for it to work!

I’ve been using my Cloud Database Backup script for a few months now for weekly scheduled backups of my MySQL databases to Google Docs. Everything has been going smoothly, however I’m starting to run low on quota. For this reason I decided to look into splitting the SQL dumps into chunks small enough to be convertible and doing an upload-convert rather than a zip upload which will result in literally unlimited, quote free database backups as frequently as I like! The focus of this post though is the actual splitting script which splits a given MySQL dump into chunks of x characters.

As always, download it here.

Ubuntu fans who like having Skype chats appearing in their Pidgin windows will know of 2 useful packages – skype4pidgin and pidgin-skype. These used to work great, however with the latest Skype update things broke. You could send messages from your Pidgin window but wouldn’t see any responses from your contacts. Frustrating!

Anyway, it looks like the guy behind skype4pidgin has come up with a solution which he’s layed out on his website.

You’ll need to download skype4pidgin.deb, libskype.so and libskype_dbus.so (or obviously the 64-bit equivalents of you’re on Ubuntu64). Drop the .so files into /usr/lib/purple-2 remembering to back up the existing equivalents first and install skype4pidgin.deb.

That should be all there is to it. Pidgin is back to working the way it should. *whew*
