How to Install CyberPanel with OpenLiteSpeed on Contabo VPS

The Power of OpenLiteSpeed on Contabo Hardware

While Nginx and Apache are excellent all-around web servers, OpenLiteSpeed is uniquely optimized for high-performance WordPress hosting. It features native support for the LiteSpeed Cache plugin, HTTP/3 (QUIC), and page-level microcaching. Paired with Contabo's multi-core processors and NVMe storage, CyberPanel turns an affordable VPS into an enterprise hosting cluster.

Prerequisites

• A fresh Contabo VPS running Ubuntu 22.04 LTS (CyberPanel works most reliably on 22.04).
• Root SSH access.
• At least 2 GB RAM (Contabo VPS 1 provides 8GB, which is more than plenty).

Step 1: Running the CyberPanel Installer

Connect to your Contabo VPS via root and launch the official CyberPanel installation script:

sudo su -
sh <(curl https://cyberpanel.net/install.sh || wget -O - https://cyberpanel.net/install.sh)

Follow the interactive installer prompts:

1. Type 1 to install CyberPanel.
2. Type 1 to install CyberPanel with OpenLiteSpeed (Free).
3. Install Full Service (includes PowerDNS, Postfix, and Pure-FTPd): Type Y.
4. For Remote MySQL, select N (install local MySQL).
5. Set a strong administrator password.
6. Install Memcached and Redis extensions: Type Y.
7. Watchdog monitoring: Type Y.

The automated script will compile dependencies and configure services over the next 5 to 10 minutes.

Step 2: Accessing CyberPanel Dashboard

Once installation finishes, reboot your server to apply all kernel and daemon updates:

sudo reboot

Open your browser and navigate to the CyberPanel management console:

https://YOUR_CONTABO_IP:8090

Accept the self-signed certificate warning, then log in using username admin and the password you configured during installation.

Step 3: Issuing Valid Hostname SSL

To access CyberPanel without browser security warnings:

1. Point a DNS A record (e.g. server.yourdomain.com) to your Contabo IP.
2. Navigate to SSL -> Hostname SSL in CyberPanel.
3. Select your domain name and click Issue SSL.
4. Now log in securely via https://server.yourdomain.com:8090.

Step 4: Deploying a 1-Click WordPress Site with LSCache

Deploying a site in CyberPanel is effortless:

1. Go to Websites -> Create Website.
2. Select Package: Default, Owner: admin.
3. Enter your production domain and an administrative email.
4. Select PHP version (choose PHP 8.2).
5. Check SSL and DKIM Support.
6. Check OpenLiteSpeed LSCache.
7. Click Create Website.

Step 5: Enabling Cloudflare DNS Integration for Automatic Wildcard SSL

CyberPanel natively integrates with Cloudflare API tokens. Navigate to DNS -> Cloudflare, enter your API token, and CyberPanel will automatically complete DNS-01 challenges for instant wildcard SSL certificates across all domains.

Frequently Asked Questions (FAQ)

Does OpenLiteSpeed read .htaccess rules automatically?

OpenLiteSpeed parses .htaccess rewrite rules upon server start. Whenever a WordPress plugin adds new rewrite rules, CyberPanel automatically restarts OpenLiteSpeed gracefully without dropping user connections.
