How to Install Flarum with Nginx on Ubuntu 24.04

Setting up a modern, lightweight discussion forum with Flarum on Ubuntu 24.04 using Nginx offers a robust and scalable solution for communities and projects. This guide walks you through the process step-by-step, ensuring a smooth installation even if you’re new to server management. Before starting, ensure your server is updated and has a clean Ubuntu 24.04 installation with root or sudo access. You will also need a domain name pointed to your server’s IP address for an optimal setup.

What You’ll Need

  • Ubuntu 24.04 server with root or sudo privileges
  • Domain name pointed to your server’s IP
  • Basic knowledge of terminal commands
  • SSL certificate (recommended for security, can be obtained via Let’s Encrypt)
  • PHP 8.2 or later, with necessary extensions
  • MariaDB or MySQL database server
  • Composer for PHP package management

Step-by-Step

  1. Update Your System 
    sudo apt update && sudo apt upgrade -y
  2. Install Required Dependencies 
    sudo apt install nginx php8.2 php8.2-fpm php8.2-mysql php8.2-xml php8.2-mbstring php8.2-zip php8.2-curl php8.2-gd unzip git mariadb-server -y
  3. Secure Your Database Server 
    sudo mysql_secure_installation

    Follow prompts to set root password and secure your database.

  4. Create a Database and User for Flarum 
    sudo mysql -u root -p
CREATE DATABASE flarum;
CREATE USER 'flarumuser'@'localhost' IDENTIFIED BY 'your_password';
GRANT ALL PRIVILEGES ON flarum.* TO 'flarumuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;
  5. Install Composer 
    php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php --install-dir=/usr/local/bin --filename=composer
php -r "unlink('composer-setup.php');"
  6. Download and Install Flarum 
    cd /var/www/
sudo mkdir flarum
sudo chown $USER:$USER flarum
cd flarum
composer create-project flarum/flarum .
  7. Configure Nginx Server Block 
    sudo nano /etc/nginx/sites-available/flarum

# Paste the following configuration:
server {
    listen 80;
    server_name your_domain.com;

    root /var/www/flarum/public;

    index index.php;

    location / {
        try_files $uri /index.php?$query_string;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2|ttf|otf|eot)$ {
        expires max;
        log_not_found off;
    }
}

# Enable the site
sudo ln -s /etc/nginx/sites-available/flarum /etc/nginx/sites-enabled/

# Test and reload Nginx
sudo nginx -t
sudo systemctl reload nginx
  8. Secure Your Site with SSL (Let’s Encrypt) 
    sudo apt install certbot python3-certbot-nginx -y
sudo certbot --nginx -d your_domain.com

# Follow prompts to obtain and install SSL certificate
  9. Configure Flarum Settings

    Visit your domain in a browser to complete the Flarum setup wizard. Enter your database details, create an admin account, and customize your forum.

Common Mistakes

  • Not pointing your domain to the correct server IP, resulting in DNS errors.
  • Forgetting to restart or reload Nginx after configuration changes.
  • Using incorrect PHP version or missing PHP extensions, causing script errors.
  • Not securing your database or server, leaving your forum vulnerable.
  • Failing to set proper permissions on the Flarum directory, leading to access issues.

Tips

  • Always back up your database before major updates or migrations.
  • Use strong, unique passwords for your database and admin accounts.
  • Enable HTTPS to encrypt data and improve security and trust.
  • Regularly update your server, PHP, and Flarum to patch vulnerabilities.
  • Configure automatic renewal of your SSL certificate with Certbot.

Troubleshooting

If your Flarum site is not loading correctly or errors appear, follow these steps:

  • Check Nginx Status: 
    sudo systemctl status nginx

    Ensure the service is active and running.

  • Review Nginx Error Logs: 
    sudo tail -f /var/log/nginx/error.log

    Look for errors related to configuration or permissions.

  • Verify PHP-FPM is Running: 
    systemctl status php8.2-fpm

    Make sure PHP processing is functional.

  • Check Database Connection: Confirm credentials and database permissions are correct. Use command-line tools to test connection.
  • Clear Cache and Reinstall Dependencies: Navigate to your Flarum directory and run 
    composer install --no-dev

    to refresh dependencies.

  • Ensure Permissions are Correct: 
    sudo chown -R www-data:www-data /var/www/flarum

If issues persist, consult the Flarum community forums or check server logs for detailed error messages.
