Create a New OpenLiteSpeed Virtual Host

OpenLiteSpeed lets you create virtual hosts with custom web root directories via the web administration console. Follow the steps below to create a new virtual host that serves web application files for the domain app.example.com and a custom web root directory on your server.

1. Create a new web root directory to use with your virtual host. For example, /usr/local/lsws/app.example.com.

   console Copy

   $ sudo mkdir /usr/local/lsws/app.example.com
   

2. Create the html, logs, and conf directories required by the OpenLiteSpeed webserver.

   console Copy

   $ sudo mkdir /usr/local/lsws/app.example.com/{html,logs,conf} -p
   

   The above command creates the following sub-directories in your web root directory:

   • html: Contains the web application files served through OpenLiteSpeed using the virtual host domain.
   • logs: Stores the virtual host access and error logs.
   • conf: Stores site-specific configurations for use with the OpenLiteSpeed web server.

3. Grant the OpenLiteSpeed console user and group lsadm full privileges to the web root directory.

   console Copy

   $ sudo chown lsadm:lsadm -R /usr/local/lsws/app.example.com/
   

4. Access your OpenLiteSpeed web administration console.

   http://SERVER-IP:7080

30. Access your virtual host domain in a new web browser window and verify that OpenLiteSpeed delivers your web application files.

    http://app.example.com

    

Secure the OpenLiteSpeed Webserver

OpenLiteSpeed serves all virtual hosts on HTTP port 80, which supports unencrypted connections between the client and web server. To enable encrypted connections, HTTPS uses port 443 with SSL certificates to secure the communication between a web browser and the server. Follow the steps below to generate trusted Let's Encrypt SSL certificates and secure your OpenLiteSpeed web 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 above generates a new Let's Encrypt SSL certificate for your virtual host domain app.example.com and its corresponding web root directory /usr/local/lsws/app.example.com/html/. Since Certbot doesn't support the OpenLiteSpeed web server profile, you will need to manually enable the generated certificate files in your virtual host configuration.

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 new SSL certificate details in your virtual host configuration.

16. Find the LSWS PID option and click Graceful Restart to restart the webserver.

17. Click GO when prompted to restart LiteSpeed and apply your 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.

Set Up Firewall Rules

UFW is enabled by default on Vultr Ubuntu servers. Configure it to allow connections to ports 7080, 443, and 80 as described below.

1. Enable UFW and allow connections to the SSH port 22 if it's inactive on your server.

   console Copy

   $ sudo ufw allow 22/tcp && sudo ufw enable
   

2. Allow connections to the OpenLiteSpeed console port 7080.

   console Copy

   $ sudo ufw allow 7080/tcp
   

3. Allow HTTP connections on the server.

   console Copy

   $ sudo ufw allow  http
   

4. Allow HTTPS connections.

   console Copy

   $ sudo ufw allow https
   

5. Restart UFW to apply your firewall changes.

   console Copy

   $ sudo ufw reload
   

6. View the firewall status and verify that the new rules are active on your server.

   console Copy

   $ sudo ufw status
   

7. Access your virtual host's domain using HTTPS in a new web browser window to test your SSL configurations.

   https://app.example.com
