Install the OpenLiteSpeed Web Server on Ubuntu

Step 1: Add the OpenLiteSpeed repository

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

Step 2: Install OpenLiteSpeed

sudo apt-get -y install openlitespeed

Step 3: Install PHP for OpenLiteSpeed

OpenLiteSpeed uses its own PHP builds, called LSPHP:

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

Use the version you want (for example lsphp82).

Step 4: See the available LSPHP packages

sudo apt-cache search lsphp

Step 5: Set the admin password

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

Enter a user name and a strong password for the WebAdmin console.

Step 6: Check the status

sudo systemctl status lsws

Start it if it is not running, and enable it at boot:

sudo systemctl start lsws
sudo systemctl enable lsws

Step 7: Open the firewall

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

• 80 and 443 are for web traffic.
• 8088 is the default example site of OpenLiteSpeed.
• 7080 is the WebAdmin console.

Open port 7080 only for your own IP address if you can.

Open the admin panel

Go to https://your_server_ip:7080 in your browser. Accept the certificate warning and log in with the admin user and password from step 5.

The default test site runs on http://your_server_ip:8088.

Benefits of OpenLiteSpeed

• Performance. An event-driven design that is fast and light on resources.
• Easy management. A web console and Apache-compatible rewrite rules, including .htaccess.
• Cost. It is free and open source.
• Security. Built-in protections such as anti-DDoS settings.
• Caching. The LiteSpeed Cache plugin for WordPress works with it.

Quick recap

• Add the repository, install openlitespeed and lsphp.
• Set the admin password with admpass.sh.
• Open port 7080 for the WebAdmin console.
