cPanel & WHM installation in CentOS 7

Installation Requirements:
Minimal installation of CentOS 7.
Minimum of 1 GB of RAM (2 GB recommended).
20 GB of free disk space (40 GB recommended).
A valid cPanel license/15 days evaluation.

Before continuing with the installation section, you must keep these important points in mind:

Note: cPanel/WHM does not have an automatic software removal system so once you install cPanel/WHM you cannot remove it from your operating system in this case a new installation of the operating system is recommended.

cPanel is a commercial software and requires a license, you can use the trial version during the first 15 days and check the characteristics of cPanel/WHM (which is activated automatically once cPanel is installed), in any case the installation of cPanel / WHM is done completely simply limits your use of cPanel/WHM administration but does not restrict active websites.

1. Disable NetworkManager (Required for cPanel installation)

[root@server ~]# systemctl stop NetworkManager.service
[root@server ~]# systemctl disable NetworkManager.service

2.We position ourselves in: /etc/sysconfig/network-scripts and edit our network configuration.

[root@server ~]# cd /etc/sysconfig/network-script
[root@server ~]# nano MYred

Editamos las siguientes líneas:

3. We enable our network and restart it with the following commands:

[root@server ~]# systemctl enable network.service
[root@server ~]# systemctl start network.service

4. We disable our firewall (Required for cPanel installation). You can enable the firewall after the installation is complete

[root@server ~]# systemctl disable firewalld
[root@server ~]# systemctl stop firewalld

Note: To enable the firewall on our CentOS 7 server it is necessary to configure all the default ports of our cPanel. You can consult the following article to open the necessary ports for cPanel & WHM.

5. Disable selinux permanently by editing the configuration file /etc/selinux/config and changing the line (SELINUX=disabled). You can enable the firewall after the installation is complete

[root@server ~]# nano /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.

6. We ensure that our server has a standard hostname (FQDN or fully qualified domain name), otherwise configure it as follows (in this example, server is the hostname and is the name of domain):

[root@server ~]# nano /etc/hosts localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 server

We also check the configuration of our hostname:

[root@server ~]# nano /etc/hostname

7. cPanel is written in Perl, make sure you have Perl installed on your server, otherwise run the following command to install it on your system.

[root@server ~]# yum install perl

8 You do not have to execute any command to install it, there is an automatic installation script created for you. All you have to do is download the cPanel installation script with the cURL command; If you do not have the cURL command installed, first install it this way.

[root@server ~]# yum install curl

9. Download the latest installation script in the home directory.

[root@server ~]# curl -o latest -L

11. Now, we run the automatic installation script. Note that if you are logged in to the server using SSH, we recommend that you run the cPanel automatic installer script in screen mode, since the installation takes between 40 and 60 minutes, depending on the server resources and Internet connection speeds.

[root@server ~]# sh latest

At this point the installation of cPanel may take about 20 minutes depending on the speed of your hardware and internet connection.

Note that cPanel will massively modify your operating system, the automatic installation script works as follows:

Examine the operating system to check the system configuration, hardware and packages installed to make sure there are no conflicts, if it finds package conflicts, it updates or uninstalls it and if it finds hardware or configuration conflicts it stops the installation.

Install several Perl modules through CPAN and other necessary packages with yum.
Download and compile PHP, FTP, Apache and other associated modules.

Once the installation is finished we can access the administration panel through the IP address configured on our server and the default port 2087.
