LOMP is an abbreviation commonly used to refer to the use of Linux software, OpenLiteSpeed, MariaDB and the command language PHP or Perl or Python to create a web server environment capable of hosting and delivering dynamic websites.

The specific functions you can understand are that LOMP works from Linux software with OpenLiteSpeed web server, MariaDB or MySQL database server and dynamic file content handled by PHP.


  • Ubuntu Server 20.04
  • Minimum VPS configuration: 1GB RAM

Implementation Guide

Step 1: SSH into the server and update the system

To upgrade the ProFTPD version on DirectAdmin, we first need to SSH or access your VPS/server with root privileges. If you don’t know how to SSH into your VPS/Server, you can refer to the following tutorial:

After successfully SSHing into the server, you proceed to update the packages installed on the Ubuntu system with the command:

AZDIGI Tutorial
sudo apt update -y && apt upgrade -y

Step 2: Install OpenLiteSpeed Web Server

Unlike Apache and Nginx, OpenLiteSpeed is hosted separately in its own repository. So to install, you need to follow the steps below:

  • Add OpenLiteSpeed’s repository to apt package to use apt install OpenLiteSpeed.

  • Check the version of Openlitespeed
AZDIGI Tutorial
/usr/local/lsws/bin/lshttpd -v
root@ubuntu20-04:~# /usr/local/lsws/bin/lshttpd -v
LiteSpeed/1.7.16 Open (BUILD built: Fri May 13 19:00:23 UTC 2022)
	module versions:
	lsquic 3.0.4
	modgzip 1.1
	cache 1.64
	mod_security 1.4
  • Open Port with Firewall

Openlitespeed uses port 8088, so please open it and some other necessary ports on UFW to access it. You use the command below to open ports at the same time as the command:

AZDIGI Tutorial
sudo ufw allow 7080,80,443,8088/tcp
sudo ufw status

Step 3: Install MariaDB Database Server

MariaDB is an alternative to MySQL. It was developed by former members of the MySQL team. You use the commands below to install MariaDB on Ubuntu 22.04.

  • Install MariaDB Database Server
AZDIGI Tutorial
sudo apt install -y mariadb-server mariadb-client
  • Some MariaDB management commands
AZDIGI Tutorial
systemctl start mariadb      (Khởi động dịch vụ mariadb)
systemctl stop mariadb       (Dừng dịch vụ mariadb)
systemctl restart mariadb   (Khởi động lại  dịch vụ mariadb)
systemctl enable mariadb     (Thiết lập mariadb khởi động cùng hệ thống)
systemctl disable mariadb    (Vô hiệu hoá mariadb khởi động cùng hệ thống )

  • Advanced Setup for Mariadb
AZDIGI Tutorial
sudo mysql_secure_installation
root@ubuntu20-04:~# sudo mysql_secure_installation


In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y                               (Nhấn Y để tạo pass root mới)
New password:  Nhập passwd root
Re-enter new password: Nhập lại passwd root
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
  • Check the version of Mariadb
AZDIGI Tutorial
mariadb --version
root@ubuntu20-04:~# mariadb --version
mariadb  Ver 15.1 Distrib 10.3.34-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

Step 4: Install PHP

At the time of writing this article, PHP 8.1 is the latest version of PHP, it has superior performance over its predecessors. Therefore, I will install PHP 8.1 and some necessary PHP modules.

  • Install lsphp81
AZDIGI Tutorial
sudo apt install -y lsphp81 lsphp81-{common,mysql}

Step 5: Configure OpenLiteSpeed

At the GUI interface, go to Server Configuration >> External App >> select edit icon

Next, scroll down to the Command section and fill in the content lsphp81/bin/lsphp. If you previously installed a different version of PHP, just replace 81 with your version of PHP.

Now go to your browser and follow the link http://IP_Server:8088/info.php to check if the PHP version has been specified correctly. If the browser displays as below, it is successful.
