In this article, we will explain how to install and configure OpenLiteSpeed – High Performance HTTP Web Server with PHP 7 and MariaDB support on CentOS 7 and RHEL 7.

Step 1: Enable OpenLitespeed Repository

1. First install and enable own OpenLitespeed Repository to install latest version of OpenLiteSpeed and PHP 7 using following command.

# rpm -ivh

Install OpenLiteSpeed Repository

Step 2: Install OpenLiteSpeed on CentOS 7

2. Now install OpenLiteSpeed 1.4 (the latest version at the time of this writing) with the YUM package manager command below; this will install it under the /usr/local/lsws directory.

# yum install openlitespeed

Install OpenLiteSpeed on CentOS-7

3. Once installed, you can start and confirm the OpenLiteSpeed version by running.

# /usr/local/lsws/bin/lswsctrl start
# /usr/local/lsws/bin/lshttpd -v

Check OpenLiteSpeed Version

4. By default, OpenLiteSpeed runs on port “8088, so you need update the firewall rules to permit port 8088 via the firewall to access OpenLiteSpeed default site on the server.

# firewall-cmd --zone=public --permanent --add-port=8088/tcp
# firewall-cmd --reload

5. Now open a web browser and type the following URL to verify the default page of OpenLiteSpeed.

http://SERVER_IP:8088/ or http://localhost:8088

Verify OpenLiteSpeed Page

Step 3: Install PHP 7 for OpenLiteSpeed

6. Here, you need to enable the EPEL repository from which you will install PHP 7 with the following command.

# yum install epel-release

7. Then install PHP 7 and a few necessary modules for OpenLiteSpeed with the command below, it will install PHP as /usr/local/lsws/lsphp70/bin/lsphp.

# yum install lsphp70 lsphp70-common lsphp70-mysqlnd lsphp70-process lsphp70-gd lsphp70-mbstring lsphp70-mcrypt lsphp70-opcache lsphp70-bcmath lsphp70-pdo lsphp70-xml

Attention: You might have noticed that here PHP is not installed in the usual way, you must prefix it with ls because there is a distinct PHP for LiteSpeed.

8. To install additional PHP modules, use the command below to list all the available PHP modules.

# yum search lsphp70

Step 4: Configure OpenLiteSpeed and PHP 7

9. Now configure OpenLiteSpeed and PHP 7, and then set the standard HTTP port 80 as explained below.

As we mentioned earlier on, OpenLiteSpeed comes with a WebAdmin console which is associated to port 7080.

Begin by configuring the admin username and password for the OpenLiteSpeed WebAdmin console; run the following command to do so:

# /usr/local/lsws/admin/misc/

Set OpenLiteSpeed Admin Account

Please specify the user name of administrator.
This is the user name required to login the administration Web interface.
User name [admin]: tecmint
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!

10. Next update firewall rules to permit port 7080 via the firewall to access the WebAdmin console.

# firewall-cmd --zone=public --permanent --add-port=7080/tcp
# firewall-cmd --reload

11. Now open a web browser and type the following URL to access OpenLiteSpeed WebAdmin console.


Enter the username and password you set above, and click on “Login“.

12. OpenLiteSpeed uses LSPHP 5 by default, you need to make a few changes to setup LSPHP 70 as explained below.

To do that, go to Server Configuration ? External App ? Add button on the right side to add new “lsphp70” as shown in the screen shot below.

Add PHP 7 Support to OpenLiteSpeed

13. Then define External App, set type to “LiteSpeed SAPI App” and click next to add the new external application’s name, address, maximum number of connections, initial response timeout, and retry timeout.

Name: lsphp70
Address: uds://tmp/lshttpd/lsphp.sock
Notes: LSPHP70 Configuration Max Connections: 35
Initial Request Timeout (secs): 60
Retry Timeout : 0

Set External App

Configure External App

The most important config here is the Command setting which instructs the external app where to find PHP executable it will use; point it to the LSPHP70 installation:

 Command: /usr/local/lsws/lsphp70/bin/lsphp 

Then click on the Save button to save the above configurations.

14. Next, click on Server Configuration ? Script Handler and edit the default lsphp5 script handler, use the values below. Once you are done, save the settings.

Suffixes: php
Handler Type: LiteSpeed SAPI
Handler Name: lsphp70
Notes: lsphp70 script handler definition 

Configure Script Handler

15. The default port HTTP servers normally listen on port 80, but for OpenLiteSpeed it is 8080: change it to 80.

Click on Listeners to see a list of all listeners configurations. Then click View to see all settings of the default listener and to edit, click Edit. Set the port to 80 and save the configuration and save the settings.

Set OpenLiteSpeed Port

16. To reflect the above changes, gracefully restart OpenLiteSpeed by clicking on the restart button and click yes to confirm.

Restart OpenLiteSpeed Server

Step 5: Verify PHP 7 and OpenLiteSpeed Installation

17. Now test if the OpenLiteSpeed server is listening on port 80. Modify firewall rules to permit port 80 via the firewall.

# firewall-cmd --zone=public --permanent --add-port=80/tcp
# firewall-cmd --reload 

18. Finally verify that OpenLiteSpeed is running on port 80 and PHP 7 using following URL’s.


19. To manage and control OpenLiteSpeed service, use these commands.

# /usr/local/lsws/bin/lswsctrl start #start OpenLiteSpeed
# /usr/local/lsws/bin/lswsctrl stop #Stop OpenLiteSpeed # /usr/local/lsws/bin/lswsctrl restart #gracefully restart OpenLiteSpeed (zero downtime)
# /usr/local/lsws/bin/lswsctrl help #show OpenLiteSpeed commands

Step 6: Install MariaDB for OpenLiteSpeed

20. Install MariaDB database management system using following command.

# yum install openlitespeed mariadb-server

21. Next, start the MariaDB database system and secure its installation.

# systemctl start mariadb
# mysql_secure_installation

First, it will ask you to provide MariaDB root password, just press ENTER to set a new root password and confirm. For other questions, simply hit ENTER to accept the default settings.
