By choosing OpenLiteSpeed, you can achieve faster load times, reduced server load, and a scalable solution that grows with your needs.

Installing OpenLiteSpeed Web Server on Ubuntu

To install OpenLiteSpeed on Ubuntu, follow these detailed steps:

Step 1: Add the OpenLiteSpeed Repository

First, you need to add the OpenLiteSpeed repository to your server. This repository contains the necessary packages for installation and updates. Use the following command:

sudo wget -O - https://repo.litespeed.sh | sudo bash

This command downloads a script from the LiteSpeed repository and pipes it directly to the `bash` shell. The `wget` command fetches files from the web, while the `-O -` option outputs the file to the standard output, which `bash` then executes. This step adds the OpenLiteSpeed repository to your system, allowing you to install the server and receive updates directly.

Step 2: Install OpenLiteSpeed

Once the repository is added, proceed with installing OpenLiteSpeed using the following command:

sudo apt-get -y install openlitespeed

This command installs the OpenLiteSpeed package. The `apt-get` is a package management tool used in Ubuntu to handle software installation. The `-y` flag automatically answers ‘yes’ to any prompts during installation, allowing the process to run without interruption. This command downloads and installs the OpenLiteSpeed web server, setting it up on your Ubuntu system.

Step 3: Install PHP for OpenLiteSpeed

OpenLiteSpeed works best with PHP, as many web applications require it. Install PHP with the following command:

sudo apt-get install lsphp81 lsphp81-common lsphp81-mysql

This command installs PHP version 8.1 and the common modules and MySQL support. The `lsphp` packages are optimized for use with OpenLiteSpeed, ensuring compatibility and performance. The `lsphp81-common` package includes standard PHP modules, while `lsphp81-mysql` provides MySQL database support. This setup is essential for running PHP-based applications like WordPress, Joomla, or Drupal.

Step 4: Verify PHP Installation

To verify the available PHP packages, you can use the following command:

sudo apt-cache search lsphp

The `apt-cache search` command searches through the package database for packages that match the given keyword, in this case, `lsphp`. This allows you to view all available PHP versions and modules specifically designed for OpenLiteSpeed. This step ensures you have access to the necessary PHP versions and extensions for your web applications.

Step 5: Set the OpenLiteSpeed Admin Password

After installation, you need to set a password for the OpenLiteSpeed administrative panel. Run the following command:

sudo /usr/local/lsws/admin/misc/admpass.sh

This script sets the password for the OpenLiteSpeed web administration interface. You will be prompted to enter a username (usually `admin`) and a password. This password secures access to the OpenLiteSpeed admin panel, where you can manage your server settings and monitor performance.

Step 6: Check OpenLiteSpeed Status

Next, you need to ensure that OpenLiteSpeed server is active and running by executing:

sudo systemctl status lsws

If it’s inactive, you can run the below command:

sudo systemctl start lsws

Firewall Configuration

Ensure that your server’s firewall allows traffic on ports 80 (HTTP), 443 (HTTPS), 7080 (OpenLiteSpeed admin panel), and 8088 (custom web service port). You can use `ufw` to open these ports:

sudo ufw allow 8088,7080,443,80/tcp

Accessing the OpenLiteSpeed Admin Panel

After setting the admin password, you can access the OpenLiteSpeed admin panel by navigating to `http://your-server-ip:7080` in your web browser. Log in using the credentials you set in the previous step:
