It is the open-source version of LiteSpeed Web Server, which is a commercial web server known for its speed and performance. OpenLiteSpeed is a popular choice for web developers and administrators looking for a high-performance, open-source web server solution. It's particularly well-suited for websites and applications that require fast and efficient content delivery.

First, check for any pending system updates,

dnf update

Third-party DNF Repositories Installation

Install the wget command before anything else since you'll need it to download and install third-party dnf repositories,

 dnf install -y wget

Run the Linux command shown below to install the LiteSpeed Official repository,

wget -O - | sudo bash


[root@vps ~]# wget -O - | sudo bash

Install OpenLiteSpeed

Run the following command to install the OpenLitespeed server and related LiteSpeed PHP interpreter

dnf install openlitespeed lsphp81


[root@vps ~]# dnf install openlitespeed lsphp81

LSPHP 8.1 and the Openlitespeed server package are installed by this command. The LiteSpeed Server Application Programming Interface (LSAPI) is connected with the PHP interpreter known as LiteSpeed PHP (LSPHP).

To make sure the recently added repository is checked out by the dnf command, update the list of repositories

 dnf update

You will safeguard the OpenLiteSpeed server by changing the default administrator account after it has been set up.

Setting the Administrative Password

Before testing the server, you should set a new password for OpenLiteSpeed Admin. The below command can help us with changing the password



root@vps:~# /usr/local/lsws/admin/misc/

Please specify the user name of administrator.
This is the user name required to login the administration Web interface.

User name [admin]: Admin

Please specify the administrator's password.
This is the password required to login the administration Web interface.

Retype password:
Administrator's username/password is updated successfully!

Status of Web Server

Use the following command to look up OpenLitespeed's status

systemctl status lsws


[root@vps ~]# systemctl status lsws

Allow the following ports on the Firewalld so it's publicy accessible.

firewall-cmd --zone=public --permanent --add-port={80/tcp,443/tcp,8088/tcp,7080/tcp}
firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-service=https
firewall-cmd --reload


root@vps:~#firewall-cmd --zone=public --permanent --add-port={80/tcp,443/tcp,8088/tcp,7080/tcp}
[root@vps ~]# firewall-cmd --permanent --add-service=http
[root@vps ~]# firewall-cmd --permanent --add-service=https
root@vps:~#firewall-cmd --reload

Accessing OLS Dashboard

To access OpenLiteSpeed, open the URL from your web browser: http://server_domain_or_IP


And to access OLS Dashboard, open the url http://server_domain_or_IP:7080

Username: Admin and Password would be the one set from previous step. First


Create Virtual Host Configuration

The virtual hosts (or vHosts) are created so the web server can serve the relevant site data to the users.

This can be added in OpenLiteSpeed by going to the WebAdmin panel -> Virtual Hosts -> Add


Next, Enter the following details of the virtual host.

  • virtual Host Name: Enter the name of the vHost or the site being configured.
  • virtual Host Root: Enter the path where the site data are stored.
  • Config File: This is the path where the vHost configuration is stored.
  • Follow Symbolic Link: Yes
  • Enable Scripts/ExtApps: Yes
  • Restrained: Yes


Save the configuration

Open the newly created vHost and navigate to "General" tab to update the following:

  • Document Root: Enter the path where the site data are stored.
  • Domain Name: Enter the domain name being used.
  • Domain Aliases: You can enter if you have any Domain aliases (example:

Index Files

  • Use Server Index Files: No
  • Index Files: index.php index.html


Save the configuration and then restart LSWS (Graceful restart from the webAdmin panel).

SSH into the server, we will create a directory for storing the site's data

mkdir -p /var/www/ols.domainhere

Replace ols.domainhere with your actual Domain name.

Create Listeners

Select Listeners from the WebAdmin panel.

One listener can monitor all local IP addresses, or you can set up numerous listeners, each of which exclusively monitors a single IP address. Many users will find it easier to have a single listener that is then mapped to various domains, but having multiple listeners can be advantageous if, for instance, you wish to reserve particular server processors for specific sites (see the listener binding section of LSWS's documentation) or carry out unique operations on different ports.


Create a listner for websites to load over HTTP, by clicking + Add button and enter the information as shown below:


Save the configuration.

Create another listner for websites to load over HTTPS, by clicking + Add button and enter the information as shown below:


Save the configuration.

You will see the Listeners similar to below image:


Next, create virtual Host Mapping for both the Listeners that was created now.


  • Virtual Host: Select the vHost name from the dropdown.
  • Domains: Enter the Domain name here (If you have multiple domains, use *).


Virtual Host Mapping should be added for both the Listeners.

Once the configuration is added, Restart LSWS from webAdmin panel.

Install Let’s Encrypt SSL Certificate

Install Certbot by running the following command.

dnf install certbot

Use the certbot command to issue a Let's Encrypt certificate. Replace and with your domain name and email :

certbot certonly --non-interactive --agree-tos -m --webroot -w /var/www/ols.domainhere -d


[root@vps ~]# certbot certonly --non-interactive --agree-tos -m --webroot -w /var/www/ols.domainhere -d
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for

These files will be updated when the certificate renews.
Certbot has set up a scheduled task to automatically renew this certificate in the background.

After certifiate is created successfully, add the Private Key file and Certificate file paths in the SSL section of the vHost configuration that was created earlier.

And then restart the LSWS once again for the changes to take effect. First

This concludes the topic of installing OpenLightSpeed on AlmaLinux 9 along with configuring vHost and SSL Certificates.
