Installing and Configuring MySQL for Vanilla Forum
Vanilla Forum requires a database to store user data, discussions, and configuration settings. MySQL is a stable and widely supported option that integrates seamlessly with PHP-based applications on Ubuntu 20.04.
Eerst, install the MySQL server package and ensure that the service is running correctly. After installation, you will create a dedicated database and user specifically for Vanilla Forum to improve security and maintain separation from other applications.
sudo apt install mysql-server -y
sudo systemctl start mysql
sudo systemctl enable mysql
Log in to the MySQL shell and create the database, user, and permissions.

CREATE USER ‘vanillauser’@’localhost’ IDENTIFIED BY ‘strong_password’;
GRANT ALL PRIVILEGES ON vanilladb.* TO ‘vanillauser’@’localhost’;
FLUSH PRIVILEGES;
EXIT;
Installing PHP and Required Extensions for Vanilla Forum
Vanilla Forum relies on PHP to handle application logic, user sessions, and database communication. Ubuntu 20.04 ships with PHP 7.4, which is fully compatible with Vanilla Forum.
To ensure full functionality, several PHP extensions must be installed, including modules for MySQL, internationalization, file handling, and HTTP requests. Installing all required extensions at once avoids runtime errors during the web-based installation.
sudo apt install php php-fpm php-mysql php-gd php-intl php-mbstring php-curl php-cli php-zip -y
Once installed, verify that PHP-FPM is running properly.
sudo systemctl status php7.4-fpm
Downloading and Deploying Vanilla Forum Files
After preparing the server environment, the next step is to download the Vanilla Forum package and place it in the correct web directory. The recommended location for Nginx-based installations is /var/www.
Download the latest Vanilla Forum core package and extract it into a dedicated directory.
wget https://open.vanillaforums.com/get/vanilla-core.zip
sudo unzip vanilla-core.zip -d /var/www/vanilla
sudo mv /var/www/vanilla/package/* /var/www/vanilla
Set the correct ownership and permissions so the web server can read and write the required files.
sudo chown -R www-data:www-data /var/www/vanilla
sudo chmod -R 755 /var/www/vanilla
Configuring Nginx for Vanilla Forum
Nginx must be configured to serve Vanilla Forum files and correctly process PHP requests through PHP-FPM. This configuration ensures clean URLs, proper routing, and secure execution of PHP scripts.
Create a new Nginx server block configuration file for Vanilla Forum.
sudo nano /etc/nginx/conf.d/vanilla.conf
Add the following configuration, replacing forum.example.com with your actual domain name.
server {
listen 80;
server_name forum.example.com;
root /var/www/vanilla;
index index.php index.html;
location / {
try_files $uri $uri/ /index.php?q=$uri&$args;
}
location ~ \.php$ {
include fastcgi_params;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_index index.php;
}
}
Test the configuration and reload Nginx.
sudo nginx -t
sudo systemctl reload nginx
Securing Vanilla Forum with SSL Using Let’s Encrypt
Encrypting traffic with SSL is crucial for safeguarding user credentials and enhancing trust. Let’s Encrypt provides free SSL certificates that integrate directly with Nginx on Ubuntu 20.04.
Install Certbot and the Nginx plugin.
sudo apt install certbot python3-certbot-nginx -y
Request and install the SSL certificate.
sudo certbot –nginx -d forum.example.com
Verify automatic renewal to prevent certificate expiration.
sudo certbot renew –dry-run
Configuring the Firewall for Forum Access
Ubuntu servers often use UFW to control inbound traffic. To ensure users can access the Vanilla Forum securely, HTTP and HTTPS ports must be allowed.
Enable and configure the firewall with the following commands.
sudo ufw allow http
sudo ufw allow https
sudo ufw reload
sudo ufw status
Completing the Vanilla Forum Installation via Browser
Once the server-side configuration is complete, Vanilla Forum must be installed through its web-based installer. This step finalizes database connections and administrator settings.
Open the following URL in your browser:
https://forum.example.com
Enter the database name, gebruikersnaam, and password created earlier, then create the administrator account. After completion, Vanilla Forum will be fully operational and ready for customization.
Operational Considerations for Production Deployments
Proper operational discipline helps prevent downtime, data loss, and performance bottlenecks. This includes keeping PHP and system packages up to date, monitoring server load, and ensuring that database operations are optimized. For larger forums, scaling considerations may include caching strategies and fine-tuning MySQL performance. Ubuntu 20.04 provides a stable and secure foundation. Key operational practices include:
- Log Management:
Regularly rotate and archive server and application logs to prevent disk space exhaustion and simplify troubleshooting. - Database Backups:
Schedule automated MySQL backups to safeguard forum data against accidental deletion, corruption, or hardware failure. - PHP Version and Extensions Monitoring:
Ensure that PHP and its required extensions are kept compatible with Vanilla Forum updates to avoid runtime errors. - MySQL Performance Optimization:
Monitor slow queries and optimize indexes as forum activity grows to maintain fast page loads and reduce server strain. - Server-Level Caching:
Implement caching mechanisms such as Redis or Varnish to reduce database load and accelerate response times for high-traffic forums. - Regular System Updates:
Keep Ubuntu 20.04 and all installed packages updated to patch security vulnerabilities and improve system stability. - Monitoring and Alerts:
Use server monitoring tools to track CPU, geheugen, en schijfgebruik, and configure alerts for abnormal activity to respond quickly to potential issues.
