Step-by-Step cPanel Installation

Hello everyone. WHM/cPanel is one of the best panels in the Web Hosting industry. So, how is this cPanel installed? What is needed to install it? I'm writing step by step as I know it, not as it is written here and there. I just installed one. Let's first talk about the requirements.

Hardware Requirements:

Processor (CPU)        Minimum 1.1 GHz processor
RAM                    Minimum 1 GB RAM (I recommend at least 2 GB)
Disk Space             20GB free space (I recommend 40 GB)
Network                1 x 10/100/1000 ethernet card

Network:

At least 1 IP Address (Should not be DHCP, must be static)
1 Subnet Address
Default Gateway Address

Compatible Virtualization Software:

KVM
Linux-VServer
Microsoft Server® 2008 Hyper-V, Microsoft Server 2012® Hyper-V
OpenVZ (Only stable versions)
Oracle VM VirtualBox, VirtualBox OSE
Virtuozzo™
VMware® Server, VMware ESX Server None.
Xen, XenEnterprise™, XenExpress™, XenServer™

Supported Operating Systems

CentOS 6.x, 7.x
RedHat Enterprise Linux 6.x, 7.x
CloudLinux 6.x, 7.x

Other Requirements:

• You must install the OS as minimal. No apache, mysql etc. should be preinstalled.
• Swap space should be double the RAM amount (Minimum 2GB).
• If you're using CentOS, RedHat, or CloudLinux, the disk format must be ext4 or XFS.
• When installing CentOS 7, do manual disk partitioning. Otherwise, it may allocate only 50GB to the root directory (/).
• Before starting the installation, disable any active firewall.

First, run the update command:

yum -y update If there's a firewall, disable it: For CentOS 6:

/etc/init.d/iptables save
/etc/init.d/iptables stop
/sbin/chkconfig --del iptables

For CentOS 7:

iptables-save > ~/firewall.rules
systemctl stop firewalld.service
systemctl disable firewalld.service

Now let's disable Selinux before installation:

Open the /etc/selinux/config file using vi or nano. The file will look like this. Change the SELINUX value to disabled and save.

# 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.
SELINUX=

disabled

# SELINUXTYPE= can take one of these two values:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

After this, reboot the server. Once the reboot is complete, continue with the steps below:

Install perl:

yum -y install perl

Install curl:

yum -y install curl

Now we’re ready to begin the installation.

Simply copy and paste the command below:

cd /home && curl -o latest -L https://securedownloads.cpanel.net/latest && sh latest

For the curious ones, here's the breakdown:

cd /home # Entering the /home directory curl -o latest -L https://securedownloads.cpanel.net/latest # Fetching the installation file sh latest # Starting the installation

Accessing cPanel and WHM
Use the following ports in your browser: http://YOUR-IP:PORT or https://YOUR-IP:PORT (for SSL access).

cPanel Ports: 2082 or 2083 for SSL
WHM Ports: 2086 or 2087 for SSL

That’s it! If you have any questions, feel free to leave a comment.
