Secure the OpenLiteSpeed Webserver

OpenLiteSpeed serves virtual hosts on HTTP port 80 for unencrypted connections. To enable encrypted connections, use HTTPS on port 443 with SSL certificates. Follow the steps to generate trusted Let's Encrypt SSL certificates and secure your OpenLiteSpeed server.

1. Install the Certbot Let's Encrypt client tool using Snap.

   console Copy

   $ sudo snap install --classic certbot
   

2. Generate a new SSL Let's Encrypt SSL certificate using an HTTP-01 challenge and your virtual host web root directory. Replace app.example.com and admin@example.com with your actual details.

   console Copy

   $ sudo certbot certonly --webroot -w /usr/local/lsws/app.example.com/html/ --agree-tos --no-eff-email --staple-ocsp --preferred-challenges http -m name@example.com -d app.example.com
   

   The command generates a Let's Encrypt SSL certificate for your domain app.example.com with the web root /usr/local/lsws/app.example.com/html/. Since Certbot doesn't support OpenLiteSpeed, you must manually enable the generated certificate in your virtual host configuration.

   Your output should be similar to the one below when an SSL is successfully generated.

   Successfully received certificate.
   Certificate is saved at: /etc/letsencrypt/live/app.example.com/fullchain.pem
   Key is saved at:         /etc/letsencrypt/live/app.example.com/privkey.pem
   This certificate expires on 2025-07-05.
   These files will be updated when the certificate renews.
   Certbot has set up a scheduled task to automatically renew this certificate in the background.

3. Test the Certbot SSL certificate renewal process.

   console Copy

   $ sudo certbot renew --dry-run
   

4. Access your OpenLiteSpeed web administration dashboard.

   http://SERVER-IP:7080

5. Navigate to Listeners on the main navigation bar.

6. Click Add within the Listener List section to add a new listener.

7. Enter the following values in the respective field to listen for HTTPS requests on the server.

   • Listener Name: HTTPS
   • IP Address: ANY IPv4
   • Port: 443
   • Secure: Yes

   

8. Click Save to add the new listener on your webserver.

9. Find the new HTTPS listener on your Listener list. Then, click View in the actions section to modify the listener details.

   

10. Click Add within the Virtual Host Mappings section to bind the listener to an existing virtual host on your server.

11. Enter the following details in the respective fields to bind your virtual host.

    • Virtual Host: app.example.com
    • Domains: app.example.com

    

12. Click Save to apply the new virtual host mappings on your webserver.

13. Navigate to the SSL tab and click edit within the SSL Private Key & Certificate section to modify your certificate details.

14. Enter the following details in the respective fields to match your Let's Encrypt SSL certificate paths.

    • Private Key File: /etc/letsencrypt/live/app.example.com/privkey.pem
    • Certificate File: /etc/letsencrypt/live/app.example.com/fullchain.pem
    • Chained Certificate: Yes

    

15. Click Save to apply the SSL certificate changes to your virtual host.

16. Locate the LSWS PID option and click Graceful Restart to restart the server.

17. Click GO to confirm the restart and apply the configuration changes.

    

    Note

    When running multiple virtual hosts on your server. Navigate to the Virtual Hosts tab, open your target virtual host, and click SSL to enable an SSL certificate to bind with the virtual host configuration.
