OpenLiteSpeed is a high-performance HTTP server, and it can handle hundreds and thousands of simultaneous connections with very low resource consumptions.

Setup openlitespeed Respository:

Use the following command to add the OpenLiteSpeed repository.

rpm -ivh

Install openLiteSpeed on CentOS 7:

Now, install OpenLiteSpeed 1.4.26 (chck) using YUM command.

yum -y install openlitespeed

Run the following command to check the version of OpenLiteSpeed and its modules.

/usr/local/lsws/bin/lshttpd -v


Controlling OpenLiteSpeed

To Start OpenLiteSpeed, run:

/usr/local/lsws/bin/lswsctrl start

To Stop OpenLiteSpeed, run:

/usr/local/lsws/bin/lswsctrl stop

To Restart OpenLiteSpeed, run:

/usr/local/lsws/bin/lswsctrl restart

To check the running status of OpenLiteSpeed, run:

/usr/local/lsws/bin/lswsctrl status


By default, OpenLiteSpeed listens on port 8088. So, you need to add firewall rules to allow port 8088 for accessing the web server.

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

Enter the URL with port no 8088 and see whether you can able to access OpenLiteSpeed or not.




Install MariaDB Server

We will now install the MariaDB server by using YUM command.

yum -y install mariadb mariadb-server

Start MariaDB server.

systemctl start mariadb

Set MariaDB service to start during every boot.

systemctl enable mariadb

Install PHP

As said in features of OpenLiteSpeed, it supports different versions of PHP installation, so we will configure OpenLiteSpeed with both PHP v5.6 and V7.0. Add EPEL repository for getting dependent packages for PHP.

rpm -ivh
Choose either one of the PHP version for configuring OpenLiteSpeed.

OpenLiteSpeed with PHP 5.6 support:

yum install -y lsphp56 lsphp56-common lsphp56-mysql lsphp56-gd lsphp56-process lsphp56-mbstring lsphp56-xml lsphp56-mcrypt lsphp56-pdo lsphp56-imap lsphp56-soap lsphp56-bcmath

OpenLiteSpeed with PHP 7.0 support:

yum install lsphp70 lsphp70-common lsphp70-mysqlnd lsphp70-gd lsphp70-process lsphp70-mbstring lsphp70-xml lsphp70-mcrypt lsphp70-pdo lsphp70-imap lsphp70-soap lsphp70-bcmath

Configure OpenLiteSpeed

In this section, we will setup OpenLiteSpeed with both PHP 5.6  & PHP 7.0, Also we will configure OpenLiteSpeed to listen on standard HTPP port 80 and via WebAdmin console.

By Default, WebAdmin console listens on port 7080 and tThe default account of OpenLiteSpeed is,

Username: admin
Password: 123456

I recommend you to change the default password for security reason. To change the password of OpenLigtSpeed admin console, run the following command.



Access WebAdmin Console

Open a web browser and visit the following URL.




Login with the admin account and the password you set few steps before


Configure OpenLiteSpeed with PHP 5.6:

You do not have to do any configuration changes to OpenLiteSpeed as it uses PHP 5.6 by default.

Configure OpenLiteSpeed with PHP 7.0:

As I said earlier, OpenLiteSpeed uses PHP 5.6. To have PHP 7.0 with OpenLiteSpeed, follow the below steps.

We already have PHP 7.0 on the server. So, go to “Server Configuration” –> “External App” –> “Add“.

Select “LiteSpeed SAPI App” and then click Next,

Add the below configuration,

Name: lsphp7
Address: uds://tmp/lshttpd/lsphp.sock
Max Connections : 35
Initial Request Timeout (secs) : 60
Retry Timeout (secs): 0
Persistent Connection: Yes
Response Buffering: No
Auto Start : Yes
Command: /usr/local/lsws/lsphp70/bin/lsphp
Back Log: 100
Instances: 1
Memory Soft Limit (bytes): 2047M
Memory Hard Limit (bytes): 2047M
Process Soft Limit: 400
Process Hard Limit: 500

Click save button to save the configuration.

Modify the default script handler to use PHP 7.0. To do that, go to “Server Configuration” –> “Script Handler” –> Edit lsphp5.

Update with the following configurations.

Suffixes: php
Handler Type: liteSpeed SAPI
Handler Name: lsphp7

Click the save icon.

Configure OpenLiteSpeed to use port 80:

Go to “Listeners” and click on “Zoom icon” in the Default listener to view the configuration.

Edit the listener.

Update with the following information.

IP Address: ANY
Port : 80

Click on the save icon.

Finally, restart the OpenLiteSpeed server.

Verify OpenLiteSpeed server:

Just enter the URL without port number and see whether you can able to access OpenLiteSpeed.





The above page confirms that the OpenLiteSpeed is listening on Standard HTTP port 80.
