OpenLiteSpeed is a lightweight, open-source web server that offers high performance and easy-to-use management. In this tutorial, we will walk through the steps to install OpenLiteSpeed on Ubuntu 22.04.

Step 1: Update Your System

Before starting the installation, update your system packages:

sudo apt update && sudo apt upgrade

Step 2: Install OpenLiteSpeed

First, add the OpenLiteSpeed repository to your system:

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

Next, install OpenLiteSpeed with the following command:

sudo apt install openlitespeed

After installation, start the OpenLiteSpeed service:

sudo systemctl start lsws

To ensure OpenLiteSpeed starts on boot, enable the service:

sudo systemctl enable lsws

Step 3: Access OpenLiteSpeed Admin Panel

By default, the OpenLiteSpeed admin panel is available on port 7080. You can access it by visiting http://your_server_ip:7080 in your web browser.

The default login credentials are:

• Username: admin
• Password: 123456

Make sure to change the default password for security reasons by running the following command:

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

Step 4: Install PHP

OpenLiteSpeed comes with multiple PHP versions. You can install PHP 7.4, for example, by running:

sudo apt install lsphp74 lsphp74-mysql

Once installed, you need to configure OpenLiteSpeed to use PHP. In the admin panel, go to Server Configuration > External App and create a new external application for PHP 7.4 using the following details:

• Name: lsphp74
• Address: uds://tmp/lshttpd/lsphp74.sock
• Max Connections: 35
• Environment: PHP_LSAPI_CHILDREN=35

Step 5: Configure Virtual Hosts

To configure a virtual host, navigate to Virtual Hosts in the admin panel and create a new virtual host. Use the default settings, but ensure the document root points to the correct directory where your website files will be located.

Step 6: Secure Your Web Server with Let's Encrypt

Install Certbot to secure your OpenLiteSpeed server with Let's Encrypt SSL:

sudo apt install certbot

Once installed, run the following command to obtain and install an SSL certificate:

sudo certbot certonly --webroot -w /usr/local/lsws/Example/html -d your_domain.com
