Installing/upgrading perl is a pretty straight forward task and is necessary for cPanel to function properly.

root@ohhai [~]# wget http://layer1.cpanel.net/perl588installer.tar.gz
root@ohhai [~]# tar -xvzf perl588installer.tar.gz
root@ohhai [~]# cd perl588installer
root@ohhai [~]# ./install

If I remember correctly, the install takes 25-30 minutes to complete depending on your server setup.

I came across this nice cheatsheet that lists all of the cPanel ports and what services they work with, so I figured I would post it up here for my own personal use, if no one else needs it.

A fantastico installation is pretty straight forward. First thing you need to do is obtain a Fantastico license from Netenburg.

One of the most common issues when installing fantastico is a buggy wget install on the server, so a working wget version will need to be installed. Another common issue is cPanels internal php may break, but we will discuss the fix to that later on.

I came across an issue for the first time where the cPanel icon was missing in the list accounts section. After digging around WHM, I found where the function was disabled.

• Log into WHM

• Select “Tweak Settings”

• Uncheck the box next to “Disable login with root or reseller password into the users’ cPanel interface. Also disable switch account dropdown in themes with switch account feature”

• Click save

After hitting save, you can go back to the list account section and the cPanel icon will be back.

Upgrading MySQL versions is a quick and easy process, not much work involved. Always be sure to make a backup before you start though, just in case the upgrade fails or some other unforeseen issue arises.

cp -Rpf /var/lib/mysql /var/lib/mysql.BAK
Login to WHM –> Tweak Settings –> MySQL -> 5.0  and Save settings
/scripts/mysqlup –force
/scripts/perlinstaller –force Bundle::DBD::mysql
/scripts/realperlinstaller –force DBD::mysql
Recompile PHP

You’re done
