Install OpenLiteSpeed Web Server on Ubuntu

In this article, we will talk about installing OpenLiteSpeed on the Ubuntu Linux system. And the steps by step solution that you need to follow.

You will get a brief introduction to OpenLiteSpeed, some of its features, and benefits. OpenLiteSpeed is a web server, primarily used for deploying PHP applications like WordPress, Ghost, and other CMS and applications.

If you are a web developer, then you must know how to install different web servers on any Linux system. So keep up with this tutorial.

What is OpenLiteSpeed (OLS)?

OpenLiteSpeed is the Open-Source edition of LiteSpeed Web Server, which is proprietary web server software. OpenLiteSpeed/LiteSpeed is the 4th most popular web server, estimated to be used by 10% of websites as of 2021. The software uses mostly the same configuration as Apache HTTP Server and is compatible with it without slowing down.

What are the Minimum System Requirements to Install OpenLiteSpeed?

To install OpenLiteSpeed on your system, then it needed to be met the minimum requirements. However, you can use an underpowered system like Intel 80486 and up. For the operating system, you can use RHEL-based distributions or Debian and Ubuntu Linux. Here are complete details about the system requirements which is required to install OpenLiteSpeed.

Operating SystemRHEL-based distributions or Debian and Ubuntu
CPUIntel 80486 and up, PowerPC G4, and ARM CPU*
Memory32 MB and more.
Storage500 MB and more (as per project requirement)
*ARM CPU usually works if you compile the software by yourself because the binary installation and the repository installation will not work.

There are other pre-requisites (not required, but you can set up after installing OpenLiteSpeed), including initial server configuration, firewall setup, and others as mentioned in the list:

  1. A domain name
  2. SSL certificate
  3. MariaDB/MySQL Database
  4. PHP
  5. Opened Firewall ports 80, 443, etc.

How to Install OpenLiteSpeed on Ubuntu?


Update System & Add LiteSpeed Repository

In case you are using a fresh/untouched Linux system, then update it first and then add the OpenLiteSpeed files repository to the apt package manager. For that, you must connect to the system using an SSH connection and execute the following commands.

sudo apt update
sudo wget -O - | sudo bash

The wget command fetches the remote repository located on the LiteSpeed server as mentioned in the link and is added to the apt package manager.


Install OLS Package and Check the service status

After adding the LiteSpeed repository, you can update the system or can go with the installing part by executing the following command:

sudo apt install openlitespeed

This installation process will prompt you to proceed or not so, type Y and click enter to install. Once the installation is completed, verify whether the OpenLiteSpeed is running or not by checking the service. So, execute the following command.

sudo systemctl status lsws

You will receive the following output:

ubuntu@olitespeed:~$ sudo systemctl status lsws
● lshttpd.service - OpenLiteSpeed HTTP Server
     Loaded: loaded (/etc/systemd/system/lshttpd.service; enabled; vendor preset: enabled)

Oct 29 20:04:40 olitespeed systemd[1]: Started OpenLiteSpeed HTTP Server.


Update System Firewall

Updating the firewall is important when we want to derive egress (outbound) and ingress (inbound) traffic on a particular project. For example, in this OpenLiteSpeed server, we will use to host the WordPress website, in that we need to allow ports 80 and 443 for HTTP and HTTPS traffic respectively.

The OpenLiteSpeed web server also comes bundled with a GUI-based admin panel and to access that we need to allow specific ports 7080 and 8088. You need to allow TCP port via UFW firewall on Linux systems (Debian/Ubuntu).

To allow access to the ports, run the following command:

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

Now, check the status of the firewall rules:

sudo ufw status


ubuntu@olitespeed:~$ sudo ufw status
Status: active

To                         Action      From
--                         ------      ----
22                         ALLOW       Anywhere                  
80,443,7080,8088/tcp       ALLOW       Anywhere                  
22 (v6)                    ALLOW       Anywhere (v6)             
80,443,7080,8088/tcp (v6)  ALLOW       Anywhere (v6)             


In case, you are using cloud services from these providers, like AWS, Azure, Alibaba Cloud, GCP, Oracle, or IBM Cloud then you must create custom security rules or need to add specific ports or port ranges to provide access.

Check out the complete detailed article about, how to set up firewall rules/security group policies for compute instances for different cloud providers.


Check Installation and Access Admin Panel

After installing and allowing the port or adding the security group rules on the system panel, you can visit the following URL to check the OLS installation. If the page shows congratulations as shown in the image, that means everything is fine.

Admin Console

Visiting the following address, you can access the GUI-based admin panel and configure the Openlitespeed server accordingly. However, the first time you must execute the command to generate the LiteSpeed admin console password. (Checkout configuration part)

How to install PHP and Database for OpenLiteSpeed?

To work with the OLS server, your system must have at least the required applications like PHP and MySQL or MariaDB Database. These two must have to deploy WordPress and other PHP-based CMS. So, follow the steps to install the latest PHP and required database for OpenLiteSpeed.

Install Latest PHP for the OpenLiteSpeed server

The OpenLiteSpeed web server comes bundled with the specific version of PHP, but not the latest version. So, using the following command you can install the latest and stable PHP for the LiteSpeed web server.

Add LiteSpeed Repository:

sudo wget -O - | sudo bash

PHP 8.0:

sudo apt-get install lsphp80 lsphp80-common lsphp80-mysql lsphp80-imap lsphp80-curl lsphp80-opcache lsphp80-intl lsphp80-redis

PHP 8.1:

sudo apt-get install lsphp81 lsphp81-common lsphp81-curl lsphp81-mysql lsphp81-opcache lsphp81-imap lsphp81-redis lsphp81-intl

When you execute the command, the system will prompt you to proceed further or not. In this case, we want to install it, so type Y and hit enter to proceed.

Install MariaDB Database for OpenLiteSpeed server

The process of installing the database for OpenLiteSpeed is the same as the Apache web server and Nginx web server, cause OLS does not come with the bundled database. So, we need to install it manually.

OpenLiteSpeed support MySQL, MariaDB, and PostgreSQL databases like Apache. For this tutorial and your production, we suggest you, install MariaDB, which is forked from MySQL database.

MariaDB is an open-source application, and it is an improvement upon MySQL. However, MySQL has its pros and cons, but for individual users MariaDB is perfect. So, to install it follow the steps mentioned below:

sudo apt install mariadb-server
installing MariaDB MySQL database on the LAMP stack
MySQL/MariaDB Installation

After executing the installation command, the terminal will prompt you to “Do you want to continue?” Type Y and press enter on the keyboard, in a few seconds, the SQL database application will be installed on the system. Using the following command, you can check the status:

sudo service mysql status
MariaDB Service Status
MySQL/MariaDB Status
Note: - This installing method will work with those systems that are based on Debian/Ubuntu Linux.

However, this process is still not completed, you must secure the database by setting up the root password and disabling remote access*. Perhaps you can check out a detailed article about MySQL/MariaDB database here.

So, use the following command to secure the database:

sudo mysql_secure_installation
Securing MariaDB 1 Database on LAMP stack Debian 10
Securing the database

When you execute the command, it will ask you a few questions following with “Enter current password for root (enter for none)” however, the new database will not have any password and we are going to set a new one, so press the enter key on the keyboard. Afterward, other questions will be asked, as I have mentioned in the list with the answers.

  1. Set root password? [Y/n] Y (You have to enter two times, the same password)
  2. Remove anonymous users? [Y/n] Y (This feature allows to login anyone without any user account)
  3. Disallow root login remotely? [Y/n] Y (To disable root logins from remote machines.)
  4. Remove test database and access to it? [Y/n] Y (MariaDB comes with a database named ‘test’ that anyone can access)
  5. Reload privilege tables now? [Y/n] Y (Ensure that all changes will take effect immediately)

How to configure the OpenLiteSpeed Web server?

The OpenLiteSpeed web server configuration will depend on your project or what purpose you have. Suppose you want to host WordPress websites, then you must configure them accordingly.
Here I am going to share the base configuration, which you will need to perform, even if you want to host the WordPress or other CMS.


Set Username and Password for Admin Console

You must set a new username and password for the OpenLiteSpeed server, whenever you install it for the first time. Without these credentials, you won’t be able to access the server configuration page. So, using the following command you can set up the credentials of LiteSpeed Admin Console.

sudo /usr/local/lsws/admin/misc/
OpenLiteSpeed admin console password
Set OLS username & password

When you execute the command to set a username and password, the system will ask you to set a new username and password as shown in the image above.

Afterward, visit the admin console link to log in to the OpenLiteSpeed configuration page.
