How to Install aaPanel on Contabo VPS: Complete Free Control Panel Setup

Why Choose aaPanel for Contabo VPS?

While cPanel and Plesk charge hefty monthly subscription fees ranging from $15 to $45/month, aaPanel provides a modular, lightweight, and modern web hosting dashboard for free. Paired with Contabo's high RAM allocations (such as 8GB or 16GB), aaPanel lets you host dozens of WordPress sites, Node.js applications, and custom Python APIs without commercial licensing costs.

Prerequisites

• A Contabo VPS running a clean installation of Ubuntu 22.04 or 24.04 LTS.
• Root or sudo administrative access.
• A registered domain name pointed to your Contabo VPS IP address.

Step 1: Preparing Your Contabo VPS

Log in via SSH and ensure all base packages are up to date:

sudo apt update && sudo apt upgrade -y
sudo apt install wget curl sudo -y

Step 2: Executing the Official aaPanel Installation Script

aaPanel provides an automated shell script specifically compiled for Debian and Ubuntu distributions:

URL=https://www.aapanel.com/script/install_7.0_en.sh && if [ -f /usr/bin/curl ];then curl -ksSO "$URL" ;else wget --no-check-certificate -O install_7.0_en.sh "$URL";fi;bash install_7.0_en.sh aapanel

During the automated installation process:

1. The installer will ask if you want to install aaPanel to the /www directory. Type y and press Enter.
2. Enable SSL for the aaPanel management panel when prompted for maximum security.
3. The process takes approximately 2 to 4 minutes depending on your Contabo CPU tier.

Step 3: Saving Credentials and Opening Firewall Ports

Once installation finishes, your terminal will display your unique login URL, safe entrance path, username, and randomly generated password:

==================================================================
aaPanel Internet Address: https://YOUR_CONTABO_IP:7800/safe_path
aaPanel Internal Address: https://10.0.0.X:7800/safe_path
username: aapanel_user
password: random_secure_password
==================================================================

Crucial: Copy these credentials and save them in a secure password manager immediately.

If you have UFW enabled on your server, permit the aaPanel management port:

sudo ufw allow 7800/tcp comment "aaPanel Web Interface"
sudo ufw allow 80/tcp comment "HTTP Web"
sudo ufw allow 443/tcp comment "HTTPS Web"
sudo ufw allow 21/tcp comment "FTP Server"
sudo ufw reload

Step 4: Choosing LNMP Stack in aaPanel

Navigate to your browser and access the secure URL. Upon first login, aaPanel displays a recommendation dialog: LNMP (Nginx) vs LAMP (Apache).

For high-concurrency sites and optimal memory performance on Contabo, select LNMP with the following versions:

• Nginx 1.24+ (High-speed asynchronous reverse proxy)
• MySQL 8.0 or MariaDB 10.11 (High-reliability ACID storage)
• PHP 8.2 or 8.3 (Modern execution engine with OPcache)
• phpMyAdmin 5.2 (Visual database management)
• FTP Server: Pure-FTPd (Optional)

Select Fast / Fast-Install (binary compilation) and click One-Click Install.

Step 5: Binding a Custom Domain & Securing aaPanel with SSL

Do not access aaPanel over bare IP in production. Instead, bind a subdomain like panel.yourdomain.com:

1. Go to Settings in the aaPanel sidebar.
2. Set Domain to panel.yourdomain.com.
3. Enable Panel SSL using Let's Encrypt.
4. Save changes. From now on, access is protected by valid 256-bit TLS encryption.

Step 6: Deploying a High-Performance WordPress Site

Deploying websites inside aaPanel is completely visual:

1. Navigate to Website -> Add site in the left sidebar.
2. Enter your production domain (e.g. example.com).
3. Under Database, select MySQL and aaPanel will automatically create an isolated database and cryptographic user credentials.
4. Select PHP-8.3.
5. Enable SSL -> Let's Encrypt to provision a 90-day auto-renewing certificate with one click.
6. Click Submit. Within 10 seconds, your web directory is ready for WordPress or Laravel deployment.

Step 7: Optimizing aaPanel on High-RAM Contabo Servers

Because Contabo Cloud VPS 1 and VPS 2 come with 8GB to 16GB of RAM, you should adjust PHP and MySQL memory ceilings in aaPanel:

• PHP-FPM: In aaPanel App Store, click PHP-8.3 -> Performance Tuning. Set max_children to 50, start_servers to 10, and memory_limit to 512M.
• MySQL: Click MySQL 8.0 -> Configuration Tuning. Increase innodb_buffer_pool_size to 2048M (or 50% of your available server RAM).
