Step 1: Adding the OpenLiteSpeed repository to the Linux server

Since the OpenLite Speed repository contains its codes, Therefore, the requirement to install OpenLite Speed on an Ubuntu Linux server is to add the OpenLite Speed repository to the server by executing the following command:

sudo wget -O - | sudo bash

The previous command you ran will add the OpenLite Speed repository to the Linux server’s apt package manager resource list by running a script.

Note: If you run thesudocommand for the first time in an SSH session, you may be asked for the password of the non-root user account.

Step 2: Updating the list of Ubuntu Server packages

After downloading and installing the Open Lite Speed repository, it is time to update the cache of the package manager. Updating the Ubuntu server packages is done to apply the OpenLite Speed repository script changes, so enter the following command to update the list of Ubuntu server packages:

sudo apt update -y

Step 3: Installing Openlitespeed and its dependencies

In this step, you will install Open Lite Speed and its dependencies:

sudo apt install openlitespeed -y

The-yoption is to confirm the command you have executed and confirm the password if requested.

Step 4: Startting the OpenLite Speed service

After the packages and dependencies are installed, you can start the Open Lite Speed service:

sudo systemctl start lsws

Step 5: Checking the status of the Open Lite Speed service

At this step, you can make sure that the Open Lite Speed service is running correctly by executing thesystemctl statuscommand:

sudo systemctl status lsws


  • lshttpd.service - OpenLiteSpeed HTTP Server
    Loaded: loaded (/etc/systemd/system/lshttpd.service; enabled; vendor preset: enabled)
    <span style="color: #008000;">Active: active (running)</span> since Mon 2023-01-16 08:59:09 UTC; 2min 26s ago
    Process: 32997 ExecStart=/usr/local/lsws/bin/lswsctrl start (code=exited, status=0/SUCCESS)
    Main PID: 33035 (litespeed)
    CGroup: /system.slice/lshttpd.service
    ├─33035 openlitespeed (lshttpd - main)
    ├─33044 openlitespeed (lscgid)
    └─33073 openlitespeed (lshttpd - #01)

Seeing Active: active (running) in the output of thesystemctl statuscommand indicates that the Open Lite Speed service is active on the Ubuntu server.

Note: You can enable and disable the automatic execution of the OpenLiteSpeed service using thesystemctlcommand.

Finally, you succeeded in installing the Open Lite Speed web server with its default configuration on the Ubuntu server, but you may not be able to access its web-based management graphical interface due to the traffic blocking of the websites’ ports. you need to make changes to the firewall and open the ports associated with websites for users to access, to access the Open Lite Speed management panel.

Access to the Open Lite Speed web-based management interface

The Open Lite Speed web server provides a management panel based on a graphical user interface and a sample website, where users can manage reports and configure SSL, Virtual Host, and Listeners through the management panel user interface. The Open Lite Speed sample website is well integrated with PHP and CGI scripts and offers a password-protected page and an error page.

To be able to access Open Lite Speed’s web-based management interface, you must configure your server’s firewall to allow traffic to pass through TCP to the ports required by the user interface-based management panel and ports 80,443,7080, and 8088.

To allow traffic on the listed TPC ports 80, 443, 7080, and 8088, run the following command:

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

Then make sure the changes you made in the firewall rules are applied by running the following command:

sudo ufw status


Status: active
To                                Action      From
--                                ------      ----
OpenSSH                           ALLOW       Anywhere
80,443,7080,8088/tcp              ALLOW       Anywhere
OpenSSH (v6)                      ALLOW       Anywhere (v6)
80,443,7080,8088/tcp (v6)         ALLOW       Anywhere (v6)

To view the sample website through port 8088, run the following command:


In the output of the previous command, you will see a page similar to the following image:

On the page you are viewing, Open Lite Speed web server capabilities are displayed.

Note that even if you do not have PHP installed, since Open Lite Speed is integrated with a version of PHP by default, you will be able to check the status of PHP running in Open Lite Speed.

In this section, you succeeded in launching Open Lite Speed on the Ubuntu server and now you can develop web applications using useful languages and frameworks.

Steps to install MariaDB on Ubuntu

In the LOMP collection, MariaDB is one of the components that is installed and set up to store, manage and retrieve website data. MariaDB is one of the most popular databases that offers advantages such as high performance and scalability.

In this part of the article, we will install MariaDB. Follow the provided instructions to set up MariaDB on the Ubuntu server.

how to install MariaDB on Ubuntu

Step 1: Installing MariaDB

Install MariaDB on the Ubuntu server by running the following command:

sudo apt install mariadb-server -y

Step 2: Starting MariaDB service

After completing the MariaDB installation, it is time to start the MariaDB service:

sudo systemctl start mariadb

You can also set the MariaDB service to be activated when the server boots by running the following command:

sudo systemctl enable

Step 3: Checking the status of the MariaDB service

By entering the following command, you can make sure that the MariaDB service is running correctly on Ubuntu:

sudo systemctl status mariadb

If you receive the message Active: active (running) in the output of the previous command, ensure that the MariaDB service is running correctly.

Step 4: Initial database server security settings

Now that you have MariaDB installed on Ubuntu, you can run a script to apply basic security settings to mariaDB by entering the following command:

sudo mysql_secure_installation

If you are asked for the password of the Root user, complete the steps by pressing the Enter button. Because there is no need to re-enter the root user password.

After you’ve applied the initial security setting, you’ll get the following output:


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...

Then, in response to the “Switch to unix_socket authentication” request, press the Y button and then Enter.

MariaDB will then ask you to specify a strong password, which will be answered by the message, “Set root password?“, press the Y, and define a strong and safe password.

After re-entering the new password, press Enter.


Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorization.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!

The next request in this regard is that you allow the Remove anonymous users. In response, press the Y button.


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

The next prompt is to Disallow logging in and accessing the database as a remote root user, Same as previous prompts, Disallow root login remotely by pressing Y and then Enter.


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!

Also, confirm the request to delete the test database and not access it by pressing the Y button:


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!

Answer the last request that is presented to confirm the changes made on the server and reload the privilege tables by pressing the Y button.


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!

Congratulations, you have installed and configured MariaDB on Ubuntu Server.

Steps to install PHP on Ubuntu

Fortunately, by installing Open Lite Speed, your Ubuntu system benefits from the version of PHP provided by the Open Lite Speed web server, but it may not be the latest stable version of PHP or you may need a special version of PHP. Therefore, in this part of the article, you can install the desired version of PHP on the Ubuntu server if needed.

how to install PHP on Ubuntu

Step 1: Checking the version of PHP installed on the Ubuntu server

To check the version of LiteSpeed PHP packages available in Ubuntu, you can also check the information about the pre-installed version of PHP on your sample website from the Test PHP section.

Checking the version of PHP installed on the Ubuntu

In addition to checking the running version of PHP that is installed with Open Lite Speed, you can check the compatibility and execution of the PHP programming language with Open Lite Speed through the Test PHP option.

You can also refer to the following address:


Step 2: Access available installable versions of PHP

After seeing the running version of PHP on the Ubuntu server, you can get the list of available PHP versions for installation by running the following command:

sudo apt-cache search lsphp

In the output of the previous command, different versions of PHP are presented for installation, which you can install according to your needs.


lsphp81 - server-side, HTML-embedded scripting language (LSAPI binary)

The PHP version is displayed in the output that we provided as an example, in which lsphp81 is interpreted as PHP v8.1, and also other versions can be identified using the extension of package names.

Step 3: Installing the required version of PHP

In this tutorial, we will install PHP v8.1 on Ubuntu, for this purpose enter the following command:

sudo apt install lsphp81 lsphp81-common lsphp81-mysql -y

The above command installs MySQL modules and PHP modules.

You can replace the extension of your desired version instead of 81.

Finally, you have successfully installed the desired PHP version, but there is a problem, that is, your sample website still uses the default PHP version of Open Lite Speed. because Open Lite Speed has not yet been configured to use the new version of PHP that you installed in this step. Therefore, the next section is dedicated to configuring OpenLite Speed to use the new version of PHP.

Configuring OpenLiteSpeed to use the new version of PHP

In this section, you need to configure Open Lite Speed to use the new version of PHP that you just installed.

1. First, create the administration account for the management panel of the web server graphical user interface using the following command:

In the output of the previous command, you will be asked to set a strong and safe username and password for the administration account:


Please specify the user name of administrator.
This is the user name required to login the administration Web interface.
User name [admin]:
Please specify the administrators password.
This is the password required to login the administration Web interface.
Retype password:
Administrators username/password is updated successfully!

Note: Remember the information you entered to create the admin account because it is important.

2. Enter OpenLiteSpeed GUI-based management panel on port 7080:
