1. You must complete a server installation of one of the supported operating systems listed on cpanel.net main page. (Install suplimentary wget and lynx)

2. You must have a server with the following minimum specifications:

At least a Pentium 3 500 MHz processor
At least a 10 GB hard drive
At least 256 MB of RAM

3. The following partitions are recommended prior to installing cPanel:

001 GB /
050 MB /boot (No seperate /boot for FreeBSD)
001 GB /tmp
010 GB /usr
007 GB /var
001 GB swap (swap should be 2x RAM)
Remaining space to /home

Note: The above partitioning scheme is assuming a 40 GB hard drive. If you have a larger hard drive, you should increment /usr & /var accordingly.

If you do not have a partitioning scheme similar to the above, it is recommended that you format & repartition your machine as you may run into operational issues in the future.

mkdir /home/cpins
cd /home/cpins
wget http://layer1.cpanel.net/latest
sh latest

At this point the installation has started and may take anywhere from 30 – 60 minutes to complete. At no point during the installation should you be prompted for user input. You will know the cPanel installation has been completed by the screen output coming to a stop & the statement “Done.” is printed on your screen. You should then hit “ctrl c” to continue.

Note: You must be on a stable connection to install cPanel. If your shell session disconnects during a cPanel install the cPanel installation will be aborted. You can restart the cPanel installation by completing “sh cpanel-*”† again, however it is recommended that you reformat your machine & start over to ensure a clean slate before placing the machine into production.
