This article will help you install WordPress with the LSCache plugin on OpenLiteSpeed using LSPHP. We are also going to see how we can use free Lets Encrypt SSL to secure your WordPress site.

This article guides you through installing and configuring OpenLiteSpeed web server, MariaDB as a database management system, LiteSpeed PHP, LetsEncrypt SSL to secure your website and Pure-FTPD (File Transfer Protocols Daemon) in case you want to use FTP to transfer WordPress files from your computer to server. The result would be to create a WordPress site on a domain (faizan.cyberpanel.net with the issuance of SSL Certificate) using OpenLiteSpeed as a web server.


Step 1: Set up OpenLiteSpeed Web Server, MariaDB and PHP on Centos 7

Step 1.1: Enable LiteSpeed Repository

A repository is a storage location where software packages are retrieved and installed on a server. We can install OpenLiteSpeed without compiling it by directly adding the LiteSpeed repository. Use the command below to enable the repository:

sudo rpm -ivh http://rpms.litespeedtech.com/centos/litespeed-repo-1.1-1.el7.noarch.rpm

Step 1.2: Installation of Components

Step 1.2.1

Now that we can access LiteSpeed repositories, we can set up the server along with the MariaDB database management system by using the following command:

sudo yum install OpenLiteSpeed mariadb-server

Step 1.2.2

Different versions of PHP are available in LiteSpeed repositories. We will install PHP version 5.6 along with the PHP extension needed to connect with the MariaDB database management system.

sudo yum install lsphp56 lsphp56-mysql

Step 1.2.3

LSPHP denotes LiteSpeed PHP. You can also search for various available extensions. Replace 56 with the corresponding PHP version to search for extensions of other PHP versions:

yum search lsphp56

Step 1.2.4

You can also install all the extensions for LSPHP 5.6 using the command below:

sudo yum install lsphp56-*

Step 1.3: Setting up the Default Admin Password

To execute and change the default admin password for OpenLiteSpeed's WebAdmin Console, use the following command and set it to 123456:

sudo /usr/local/lsws/admin/misc/admpass.sh

It will ask for a username but by default, the admin username is used. You can press Enter to accept, and use the password 123456 on a temporary basis. Later, you can change your temporary password to a strong password for protection.

Step 1.4: Adding a New PHP Link

By default, OpenLiteSpeed will use the PHP at /usr/local/lsws/fcgi-bin/lsphp5 We will create a symlink to our installed PHP version so that OpenLiteSpeed can use the PHP 5.6 that we installed earlier because it contains the MySQL extension which is required by WordPress.

sudo ln -sf /usr/local/lsws/lsphp56/bin/lsphp /usr/local/lsws/fcgi-bin/lsphp5

Now, the PHP version 5.6 at /usr/local/lsws/lsphp56/bin/lsphp will be used by OpenLiteSpeed to process PHP files.

Step 1.5: MariaDB Configuration

Step 1.5.1

Start MariaDB by using following command:

sudo systemctl start mariadb

Step 1.5.2

Enable MariaDB service automatically, when we boot our system:

sudo systemctl enable mariadb

Step 1.5.3

Run the first time command to set up and configure MariaDB:

sudo mysql_secure_installation

First, it will ask for the root password for Maria DB, but since we haven't set one, press the Enter key to proceed. Now, it will ask you to set the root password. Provide a secure and strong root password to log into MariaDB.

For the rest of the questions, you can press Enter to continue and you will successfully install MariaDB on your server along with OpenLiteSpeed and LSPHP.

Step 1.6: Confirmation

Now we will confirm the OpenLiteSpeed web page and Admin interface.

Step 1.6.1

You can check the status of your OpenLiteSpeed web server using the following command, which provides a LSWS PID:

sudo service LSWS status

Step 1.6.2

You can also browse to your server's domain name or IP address on port 8088 to view the following OpenLiteSpeed default page:


Openlitespeed web server installed

Now you have successfully installed OpenLiteSpeed web server which is running on port 8088.

Step 1.6.3

Log into the OpenLiteSpeed administrative interface by browsing to your server's domain name or IP address on port 7080:


You will see a browser warning for an invalid SSL certificate, but you can proceed by clicking the "Proceed" link as shown:

SSL not validated page warning

Step 1.6.4

After proceeding, it will take you to the OpenLiteSpeed administrative interface, where you will enter your username and default password.

web admin console for OpenLiteSpeed

Step 1.6.5

Now you are on your main server management dashboard.

Openlitespeed dashboard

Step 1.7: Change Port for the Default Page

Log into your the OpenLiteSpeed administrative interface. Go to Listeners > Listener List > View/Edit Button > from main menu bar of your dashboard, and change port 8088 to conventional port 80. Save the changes and restart the server.

restart your server for configuration

Now we have installed OpenLiteSpeed web server, MariaDB and PHP version 5.6 on Centos 7. OpenLiteSpeed web server and its administrative interface provides useful features to run and manage your websites in a user-friendly environment.

Step 2: Set up WordPress with OpenLiteSpeed Web Server on Centos 7

WordPress is the most powerful website creation tool in the world. It is the prevalent content management system (CMS). WordPress owes its popularity to a user-friendly interfance for blog, website, and post management that doesn't require a user to know any programming languages. WordPress websites are set up on top of a database back-end system that uses PHP scripts to execute the processing of dynamic content.

Let's set up WordPress with OpenLiteSpeed on CentOS 7.

Step 2.1: Prerequisites

At this point, you must have successfully installed the above prerequisites to move ahead.

Step 2.2: Creating a Database and Database User on MariaDB for WordPress

To create a database and database user for WordPress, we need to log into MariaDB with the following command:

mysql -u root -p

It will ask for the administrative password for MariaDB that you entered during installation.

Once you are logged into MariaDB, you will need to create a database for WordPress. You may choose any name for your database, but we will use cyberpanel for a simple example.


Now we will create a database user and grant it access to manage the database that has just been created. We will create a user by the name of cyberpaneluser but, again, you may name it whatever you like. Also, you can replace the password in the command section to keep it strong. We will be using password for simplicity.

GRANT ALL ON cyberpanel.* TO [email protected] IDENTIFIED BY 'password';

Use the flush command to make your changes available to the current MariaDB process.


Now, exit out of MariaDB to your regular shell.


Step 2.3: Installation of Necessary PHP Extensions for WordPress

Earlier we installed PHP 5.6 from LiteSpeed repositories. WordPress requires some additional extensions that we will install now using the command below:

sudo yum install lsphp56-gd lsphp56-process lsphp56-mbstring

Now, these extensions will automatically be available to OpenLiteSpeed web server to run WordPress.

Step 2.4: Configuration of Virtual Host for WordPress

Step 2.4.1

For the configuration of a Virtual Host, navigate to OpenLiteSpeed's administrative interface by browsing to your server's domain name or IP address on port 7080 i.e. https://your-IP-Address:7080

Step 2.4.2

Enter your username and default password to log in, then go to Virtual Hosts from the main dashboard menu bar on the left and follow the steps below:

add a virtual host

Step 2.4.3

Press the add button on the top right corner. The following window will be opened.

click to create option in virtual host

Now a Virtual Host has been created and is called "faizan.cyberpanel.net":

faizan.cyberpanel.net virtual host created

Step 2.4.4

Navigate to Virtual Hosts > faizan.cyberpanel.net > General and press the edit/view button to make the following changes:

general tab in virtual host faizan.cyberpanel.net

Step 2.4.5

Navigate to  Virtual Hosts > faizan.cyberpanel.net > General > Index Files and press the edit/view button. In the Index files field, add index.php before index.html to allow PHP index files to take precedence. Now, save changes and restart your server.

Step 2.4.8

From the OpenLiteSpeed administrative main dashboard, navigate to: Listeners > Listener List > Virtual Host Mappings, press the edit/view button, and make the following changes:

virtual host mappings in OpenLiteSpeed

At this point, we have completed the necessary virtual host tasks required to run WordPress on faizan.cyberpanel.net. Now, we will install and configure WordPress in the /home/wordpress directory on CentOS 7.

Step 2.5: Install and Configure WordPress

Step 2.5.1

Now we are ready to download and install WordPress to the /home/wordpress directory that we set up on the Virtual Host Root and Document Root.

cd /home
wget https://wordpress.org/latest.tar.gz

Step 2.5.2

Extract WordPress:

tar xzvf latest.tar.gz

Now, WordPress has been installed in /home/wordpress.

Step 2.5.3

Set permissions on the WordPress directory so that the user which runs the web server may make changes through the WordPress interface.

chown -R nobody:nobody /home/wordpress/

Now we have successfully downloaded and extracted WordPress in the /home/wordpress directory.

Step 2.6: Complete Installation through the WordPress Interface

Step 2.6.1

Now, with the files downloaded to /home/wordpress, we can access WordPress by going to the faizan.cyberpanel.net/index.php domain that we set up for running WordPress in Virtual Hosts.

Step 2.6.2

Press Continue to proceed; the next page will ask you to enter the following things for validation:

Step 2.6.3

After adding the above information, enter Site Title, Username, Password, and Your Email for authentication.

Wordpress installation and configuration from interface

Press the Install WordPress button.

Step 2.6.4

Enter your username and password to log into the main dashboard of your WordPress website:

Step 3: Set up the LSCache Plugin

The LSCache plugin for WordPress works by generating static HTML pages of your WordPress website and saving them on your server. The main benefit of this feature is that when a user tries to access a website, LSCache provides a lighter HTML page, instead of running the heavy PHP scripts, and gathering data from the beginning. LSCache is installed on servers to improve the load time of a website through this process.


Step 3.1: LSCache Configuration

The LSCache server module installed and enabled itself when you first set up OpenLiteSpeed. You need to set the LSCache parameters to the following by going to Openlitespeed's Administrative Interface > Main Dashboard > Server Configuration > Modules > Server Modules Definition > View/Edit Button > Module Parameters.

checkPrivateCache   1
checkPublicCache    1
maxCacheObjSize     10000000
maxStaleAge         200
qsCache             1
reqCookieCache      1
respCookieCache     1
ignoreReqCacheCtrl  1
ignoreRespCacheCtrl 0

enableCache         0
expireInSeconds     3600
enablePrivateCache  0
privateExpireInSeconds 3600

LSCache configuration

Save changes and restart your server.

Step 3.2: Set LSCache Rewrite Configuration for Virtual Hosts

Now, go to Virtual Hosts > faizan.cyberpanel.net > Rewrite Rules, press the edit/view button, and make the following changes:

LSCache Rewrite configuration in Virtual Hosts

Step 3.3: Activate LSCache WordPress Plugin

Step 3.4: Verify LSCache Activation

X-LiteSpeed-Cache: hit

This means the LSCache plugin for WordPress is successfully activated and is caching your site.

Step 4: Set up LetsEncrypt SSL on CentOS 7

SSL stand for Secure Socket Layer, and it is used to ensure privacy, authentication and data protection in Internet communication. It uses the HTTPS protocol and encryption to secure your website from threats and an insecure environment.

Step 4.1: Install Acme.sh

To install acme.sh, execute the command below:

wget -O -  https://get.acme.sh | sh

You will see an output in which acme.sh is installed to /root/.acme.sh/ directory.

Step 4.2: Issue a LetsEncrypt Certificate

The following command is used to issue a LetsEncrypt certificate for a single domain, i.e. faizan.cyberpanel.net.

/root/.acme.sh/acme.sh --issue -d faizan.cyberpanel.net -w /home/wordpress


acme.sh results

In the output, the certificate key and full chain certificate key are outlined in red. Now you will need to enter these two keys in the Virtual Hosts area.

Step 4.2.1

Navigate to Virtual Hosts > faizan.cyberpanel.net > SSL > SSL Private Key and Certificate, press the edit/view button, and make the following changes:

SSL configuration in virtual hosts

Step 4.2.2

Go to Listeners > Add Listener, and make the following changes:

create a new listener for SSL

Step 4.2.3

Go to Listeners > Listeners faizan.cyberpanel.net > Virtual Host Mappings > SSL > SSL Private Key and Certificate, press the edit/view button, and make the following changes:

Listeners SSL in virtual hosts

Step 4.2.4

Go to your browser visit your index page, like so: https://faizan.cyberpanel.net/index.php

LetsEncript SSL is setup successfully

You have now successfully installed LetsEncrypt SSL on CentOS 7 for the domain faizan.cyberpanel.net. You can follow the steps mentioned above to do the same for your own website in an easy way.
