With such wealth of features, let us get OpenLiteSpeed installed on Ubuntu 20.04 and Debian 10.

Step 1: Add LiteSpeed Repository

The provided APT repository contains all the latest packaged for LiteSpeed. Add the repository to your Ubuntu | Debian system by running the following commands in your terminal.

wget -O - http://rpms.litespeedtech.com/debian/enable_lst_debian_repo.sh | sudo bash

Step 2: Install OpenLiteSpeed

With the repository added you can install OpenLiteSpeed web server on Ubuntu 20.04 | Debian 10 Linux machine using apt package manager.

You need to make sure APT list is updated before installation is done.

sudo apt update
sudo apt-get install openlitespeed

Step 3: Install PHP on Debian | Ubuntu

The commands below will install PHP 7.4 with all commonly-used packages for OpenLiteSpeed from LiteSpeed’s Debian Repo. Following the install, the soft link created will direct OpenLiteSpeed to use the installed PHP.

This build of PHP should be enough to support the most commonly used web applications. If you wish to install an older version such as PHP 5.6, replace lsphp74 to lsphp56.

sudo apt-get install lsphp74
sudo ln -sf /usr/local/lsws/lsphp74/bin/lsphp /usr/local/lsws/fcgi-bin/lsphp5

To start the server, we shall run /usr/local/lsws/bin/lswsctrl start and to stop it, we shall run /usr/local/lsws/bin/lswsctrl stop

$ sudo /usr/local/lsws/bin/lswsctrl start
[OK] Send SIGUSR1 to 94667

Step 4: Setting the Administrative Password

In order to login to the DirectAdmin control panel, we have to generate an Administrative Password. OpenLitespeed ships with a script to help us with this part. Simply run the command below

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

Please specify the user name of administrator.
This is the user name required to login the administration Web interface.

User name [admin]: Geeksadmin

Please specify the administrator's password.
This is the password required to login the administration Web interface.       

Password: 
Retype password: 
Administrator's username/password is updated successfully!

Running the above will ask you to provide a username. Pressing ENTER without choosing a new username defaults to admin as the new administrative username. Later, you will be prompted to create and confirm a new password for the account. Kindly provide the details then proceed to login.

Step 5: Access OpenLiteSpeed Web Admin on Ubuntu | Debian

As it had been touched on in the features, OpenLiteSpeed comes with friendly Admin Interfaces (Builtin WebAdmin GUI, CyberPanel, or DirectAdmin control panel). The default port that the WebAdmin console listens from is 7080. Point your browser to http://your-server-ip:7080 and you should get a login page as shown below. Enter the username and password you just created.

And you should be ushered into a dashboard similar to the screenshot below

Step 6: Creating a Test Virtual Host on OpenLiteSpeed

From the interface, it is very easy to create a virtual host. Simply click on the “Virtual Hosts” tab and click on as illustrated below. You will be presented with a form where you will fill with details that correspond to your settings.

Fill in the form with the details corresponding to your desired configuration.

Let us create a sample php file in the Default Virtual Host directory to check of our webserver is working well. By default, the OpenLiteSpeed virtual host accepts connections on port 8088. If you point your browser to that port, you should see a page like below:

So to serve our test page, we will point our browser to http://your-server-ip:8088/file-name

Create a sample php test file

$ sudo vim /usr/local/lsws/Example/html/test.php



<?php
echo '';
?>


        <?php
               echo '
This is to confirm that our PHP is working
';
        ?> 
                
OpenLiteSpeed
               
OpenLiteSpeed is a high-performance, lightweight, open source HTTP
               server edition of LiteSpeed Web Server Enterprise

Point our browser to http://your-server-ip:8088/test.php

And our webserver is in good shape!

Step 7: Change default Virtual Host Listening Port

If you are unhappy with the default port 8088 where Virtual Hosts listen for connections by default, you can change the value to the one you are comfortable with. Click on “Listeners” then on “View” as illustrated on the image below.

That will open the Listeners configuration page. On the page, click on the edit icon to alter with the defaults. The image below illustrates that.

Once editing has been enabled, you are free to choose the port of your choice. After you are done, save your configurations by clicking on the save icon as illustrated below.

As you may have guessed, openlitespeed webserver has to be restarted to create the new changes. Click on the grace restart button and you will be good to go.

You can go ahead and test your file against the new port. Remember to allow the port on your firewall if you have one running.
