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.

When a client want to get email from other server you need to change MX (change from WHM/Edit a DNS Zone not from cPanel)

1. In DNS Zone do that:

domain.com. 14400 IN MX 0 any.domain.com.

2. Add new entry

any.domain.com. 14400 IN A 123.123.123.123

Change last figure of Serial Number and click Save. Restart Bind

3. Make a ssh connection and remove the domain name from /etc/localdomains

Add the domain name in /etc/remotedomains

Restart Exim

You need to wait aprox. 4 hours to work

If the domain name are pointed to Email server and from there are redirected the www do that:

1. Remove the DNS Zone from WHM

2. Make a ssh connection and remove the domain name from /etc/localdomains

Add the domain name in /etc/remotedomains

Restart Exim
