To check your system’s host name and network configuration:
– Log on to the system as the root user.
– Type vi /etc/hosts to open the host file and modify the contents.
– Verify that the file is in the following format:

– Verify that the loopback entry (127.0.0.1) appears in the file. A correctly configured file should look like this:

Note : The IP addresses used here are for illustration purposes only; they are not valid values.

Quote:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
10.1.1.1 myhost.mydomain.com myhost

– Modify the file as needed.
– Type :wq to close the file.
– Type vi /etc/sysconfig/network to open the network sysconfig file and modify the contents.
– Verify the host name. A correctly configured file should look like this:

Note : The IP addresses used here are for illustration purposes only; they are not valid values.

Quote:
NETWORKING=yes
HOSTNAME=myserver.mydomain.com
GATEWAY=10.100.0.1

– Modify the file as needed.
– Type :wq to close the file.
– Type vi /etc/sysconfig/network-scripts/ifcfg-eth0 to open the network scripts file and modify the contents.
– Verify that network information. A correctly configured file should look like this:

Note : The IP addresses used here are for illustration purposes only; they are not valid values.

Quote:
DEVICE=eth0
BOOTPROTO=static
BROADCAST=10.1.1.1
IPADDR=10.1.1.1
NETMASK=255.255.0.0
NETWORK=10.1.0.0

[3]cPanel Installation Instructions:

Quote:
Important : You must have a valid cPanel license. If you do not have a valid cPanel license, please contact one of cPanel distributors listed at http://www.cpanel.net/dist.htm or buy a license directly from cPanel at http://www.cpanel.net/store/.

cPanel now uses a universal install script which can be found at http://layer1.cpanel.net/. You can use the following commands in the root shell to download and start the installation script:

Quote:
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.

[4]cPanel/WHM Configuration:

Following a successful install you should setup cPanel/WHM as soon as possible. In order to complete this process you will need to log into your machine using its main (eth0/fxp0) IP address; you should input something similar to this into your browser:

Quote:
https://xxx.xxx.xxx.xxx:2087

Note: you should replace xxx.xxx.xxx.xxx with your actual IP address. Further to that, you will be prompted about a self signed SSL certificate; ignore this by clicking on “Yes”. A self signed certificate is generated by cPanel/WHM to ensure a secure/encrypted communication with your server.

You will now be prompted with a few questions related to how you would like your installation of cPanel/WHM customized. You can walk through the wizard by clicking on “Next Step” or if you are an experienced user feel free to click on “Finish” to skip to the end.

For a complete user guide on how to access cPanel/WHM and/or use any of the functions within cPanel/WHM, please visit cPanel documents section at http://www.cpanel.net/docs.htm

That’s all for now .. Just keep in mind, this is not the all-in-one package for server installaion, you’ll have to secure the server, update your kernel, install a firewall, configure SSH, apply patches …. etc,etc,etc,etc Zzzzzzzzzzz

This was just to illustrate the BASIC steps to get you online.
