# Installation

To install the CloudLinux Subsystem on an Ubuntu machine:

1. Make sure you have Python 3 installed on your system. If not, install it using the following command:

apt install python3

2. Download the ubuntu2cloudlinux.py script:

wget https://repo.cloudlinux.com/cloudlinux-ubuntu/sources/cln/ubuntu2cloudlinux.py

3. Run the script. Provide a key if your license is key-based:

python3 ubuntu2cloudlinux.py --key=your_key

If you have an IP-based license, pass the --byip option instead:

python3 ubuntu2cloudlinux.py --byip

The script will install the CloudLinux Subsystem on your Ubuntu machine. After the installation is complete, reboot your system.

# Ubuntu2Cloudlinux explained

The ubuntu2cloudlinux.py script installs the CloudLinux Subsystem For Ubuntu. It is a simpler script compared to the CLdeploy script for CentOS and AlmaLinux. For example, it doesn't replace the Linux kernel, only adds a dynamic module to it. Here is a list of actions that the ubuntu2cloudlinux script performs:

• Checks that you are running the latest available version of the ubuntu2cloudlinux.py script, and updates itself if necessary.
• Upgrades all installed packages to the latest versions (unless the --skip-full-update option is passed).
• Registers your system with the CloudLinux Network (CLN) using the provided key or IP address.
• Adds CloudLinux repositories for Ubuntu and a corresponding GPG key to your system.
• Installs a minimum set of CloudLinux OS components: lve, kernel module kmodlve-dkms, lve-utils, lve-stats, alt-python.
• Installs CloudLinux Manager (currently works with cPanel on Ubuntu).
• Installs the mod_hostinglimits Apache module.
• Asks you to manually reboot the system to load the new kernel module.
