How to Install cPanel/WHM on Ubuntu 20.04

Before the installation, we need to know if we meet the minimum requirements to install cPanel & WHM.

Your hostname must meet the following requirements:

• Registered and fully-qualified domain name.
• Does not match any of your server’s domains.
• Be a maximum of 60 characters in length.
• Resolve to a valid IPv4 or IPv6 address.

Your system must meet the following requirements:

• Have a valid IP address.
• Have a valid subnet address.
• Have a default gateway IP address.
• Have a 1:1 NAT and NAT loopback configuration if your server resides on a NAT-configured network.

Ethernet device:
Your Ethernet device needs to be set up with a fully-qualified hostname and static IP address. During installation, the system will recognize and configure the Ethernet device.

Firewalls
During the installation process, the installer will try to open the required ports. Before starting the installation of cPanel and WHM, we advise you to turn off any OS firewalls. We advise that after the installation is complete, you configure a firewall using a third-party client like APF or CSF.

Run the commands below on Ubuntu to disable firewalls, where /firewall.rules is the name of the firewall rules file:

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

Hardware requirements
Operating system and version: Ubuntu 20.04 LTS
Processor: Minimum: 1.1 GHz
RAM: Minimum: 1 GB
Disk Space: Minimum: 20 GB
Architecture: 64-bit

Once you have the minimum requirements to install cPanel & WHM let’s start to install them.

To install cPanel & WHM on your server, run the following command:

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

The output should look like this:

Congratulations! Your installation of cPanel & WHM 11.104 is now complete. The next step is to configure your server. 

Before you configure your server, ensure that your firewall allows access on port 2087.

After ensuring that your firewall allows access on port 2087, you can configure your server.

1. Open your preferred browser

2. Navigate to the following url using the address bar and enter this one-time autologin url:

https://ipaddress.cprapid.com:2087/cpsess1318174995/login/session=root%3aCu3YdDv8v1h0VGPN%3acreate_user_session%2c8214a31f4137e0ffe402579f015cc302

After the login url expires you generate a new one using the 'whmlogin' command or manually login at:

https://server-ip:2087
