Install cPanel ,Install cPanel/WHM, Install cPanel in linux, Install cPanel in centos

Before installing cPanel/whm on your Server or VPS, we need to take two additional steps.
First we need to make sure that Perl is installed on the server:

 yum install perl

After installing perl we need to take one more preliminary step.
cPanel is very picky about making sure that server that it is installed
on has a Fully Qualified Domain Name. To that effect, we need to
provide it with a valid hostname. Skipping this step will inevitably get
you the following, very common, error:

2014-10-01 16:00:54  461 (ERROR): Your hostname () is not set properly. Please
2014-10-01 16:00:54  462 (ERROR): change your hostname to a fully qualified domain name,
2014-10-01 16:00:54  463 (ERROR): and re-run this installer.

Luckily this error has a very easy solution. If you have a FQDN, you can type it in with the command:

hostname your FQDN

Otherwise, if you want to proceed with the cPanel installation but do
still lack the hostname, you can input a temporary one. Once cPanel is
installed, you will be able to change the hostname to the correct one on
one of the first setup pages.

hostname  host.example.com

Although the cPanel installation only has several steps, the
installation does take a long time.

you can proceed to install cPanel with WHM or a DNS only version of cPanel.

Once cPanel finally installs, you can access the login by going to
your ip address:2087 (eg. 12.34.45.678:2087l) or domain
(example.com:2087)
Your login will be:

username: your_server_user
password: your_password

From there, you can create your cpanel user and finally login in at ipaddress/cpanel or domain/cpanel.
