There are certain prerequisites that must be followed when installing cPanel or WHM Plus. The basic concepts to be aware of when installing cPanel are as follows:
At first, one should be sure of the fact that the cPanel license, which is being used, has been purchased from the cPanel website. This is because the license is not free; the user has to buy it from the correct source. The IP you would use must be authorized to use cPanel. Also, the hostname of the server must also be valid. The ports that will be used to access cPanel must be opened on the server’s firewall. This can be done using the ‘iptables command’.
It is strongly recommended that the user follow the proper tutorial before installing the system on the server. Also, it is mandatory that cPanel is installed on a clean server because if other applications are already present on the server, the cPanel installation might fail. In case other applications are already installed on the system, it is recommended to use the Rebuild function of the control panel which helps to create server images. The Perl installation is important for the cPanel installation to run. Another important aspect of having a perfect cPanel installation is having an uninterrupted connection.
There are a few ways to access cPanel or WHM Plus with or without the use of SSL. The things to be followed are:
The port value used to communicate with remote servers such as cPanel, WHM, and Webmail is HTTP or HTTPS over an encrypted connection.
The host address can have an IP address or a domain name. When an end user uses a domain name to access cPanel or WHM Plus, it is mandatory that the DNS information for the domain has been propagated through the domain system. Most of the websites that are accessed by http or https, in them the port number is already implicit. On the other hand, the cPanel and WHM services use their individual port numbers. Therefore, it is important that if one wants to access a service through cPanel or WHM services, he must specify the port number regardless of the type of connection.
When a user logs into the cPanel or WHM Plus server, a security token is automatically added to the URL. The security token is required for authorized use of a website. As far as access is concerned, if the cPanel interface cannot be accessed with the domain name, the IP address of the domains can be tested. Generally it is seen that it takes two to three days for the domain to fully propagate after the website has been set up. Once the domain has been successfully propagated, the website can be navigated using the domain name.
Therefore, the necessary steps for the correct functioning of cPanel or WHM Plus have been clearly defined. By following all the steps correctly, a user can take advantage of the benefits of cPanel or WHM.
