Vultr's One-Click OpenLiteSpeed application is a ready-to-run Open Source edition of LiteSpeed Web Server Enterprise. Select a server location, choose the instance size, and click Deploy Now. Your web server is ready to use in about a minute. One-Click OpenLiteSpeed is available on either Ubuntu or CentOS.

The examples and are used throughout this guide. Substitute your server's domain name or IP address.

Let's Encrypt SSL Certificate

Most administrators use a domain name and valid SSL certificate for their site. If you use a free Let's Encrypt certificate, the certbot utility manages your certificate requests and renewals. See the certbot website for complete details.

  1. Register a domain name and create a DNS record for the server's IP address. Consult your DNS provider for instructions, or see our guide if using Vultr's DNS.

  2. Verify the DNS has finished propagation, and the name is visible throughout the internet before proceeding. Propagation usually happens quickly, but could take up to 48 hours in some cases.

  3. Connect to your server, with the root login from the Server Information screen.

  4. Install Certbot for your OS.

    CentOS: Install the EPEL repo, then install certbot.

     # yum install
     # yum install certbot

    Ubuntu: Update the apt package database, add the certbot repository, then install certbot.

     # sudo apt-get update
     # sudo apt-get install software-properties-common
     # sudo add-apt-repository universe
     # sudo add-apt-repository ppa:certbot/certbot
     # sudo apt-get update
     # apt-get install certbot
  5. Install the certificate with certbot. The webroot-path /usr/local/lsws/Example/html is the default for OpenLiteSpeed. Replace the domain name and email with your values.

     # certbot certonly --webroot --redirect --agree-tos --no-eff-email \
        --webroot-path /usr/local/lsws/Example/html -d -m 

    Certbot should report success when finished.

  6. Navigate to

  7. Proceed past the certificate warning. See our instructions to bypass the HTTPS warning for self-signed SSL/TLS certificates. Log in with your User login.

  8. Click Listeners on the left menu.

  9. Click the Defaultssl entry.

  10. Click the SSL tab.

  11. Edit SSL Private Key & Certificate.

  12. Set Private Key File to: /etc/letsencrypt/live/

  13. Set Certificate File to: /etc/letsencrypt/live/

  14. Click Save.

  15. Click your server name in the top-left corner, then click Graceful Restart.

Commercial SSL Certificate

You can use a Commercial SSL Certificate instead of the free Let's Encrypt certificate.

  1. Obtain a certificate from a certificate authority for your domain.

  2. Connect to your server, with the root login from the Server Information screen.

  3. Replace the server.crt and server.key files in /usr/local/lsws/conf/ with the commercial certificate. Refer to your certificate vendor's documentation for details.

  4. Reboot the server.

     # reboot

About One-Click Apps

One-Click apps are updated regularly without notice. When launching a One-Click app, you'll receive our latest version. We do not update deployed instances, and you are responsible for keeping the instance up-to-date. If you design an infrastructure based on One-Click apps and need to ensure the same app version in the future, take a snapshot of the initial deployment and create new instances from the snapshot.
