Prerequisites and System Requirements

Before beginning the MyBB installation process, ensure your Ubuntu 24.04 LTS server meets the necessary requirements. Your system should have at least 2GB of RAM and 20GB of available storage space for optimal performance. A dual-core processor will handle moderate traffic loads effectively.

Essential Requirements:

• Fresh Ubuntu 24.04 LTS installation with root or sudo access
• Stable internet connection for downloading packages
• Basic familiarity with command-line operations
• Domain name configured (optional but recommended for production)

Security Considerations:
Configure your firewall settings before installation and ensure SSH access is properly secured. Consider implementing fail2ban for additional protection against brute force attacks. Having a backup strategy in place before installation helps prevent data loss during configuration.

Step 1: Update Ubuntu System

System updates form the foundation of a secure MyBB installation. Begin by refreshing your package repositories and installing available updates.

sudo apt update && sudo apt upgrade -y

This command combination updates package lists and upgrades all installed packages to their latest versions. After the upgrade completes, reboot your system to ensure all kernel updates take effect:

sudo reboot

Clean your package cache to free up disk space:

sudo apt autoremove && sudo apt autoclean

Step 2: Install and Configure Web Server

MyBB requires a web server to function properly. You can choose between Apache and Nginx based on your specific requirements and preferences.

Apache Installation and Configuration

Apache HTTP server provides excellent compatibility with PHP applications like MyBB. Install Apache using the following commands:

sudo apt update
sudo apt install apache2

Configure Apache service management:

sudo systemctl stop apache2
sudo systemctl start apache2
sudo systemctl enable apache2

Test your Apache installation by navigating to http://localhost in your web browser. You should see the Apache2 Default Page confirming successful installation.

Nginx Alternative Installation

For high-traffic forums or resource-constrained environments, Nginx offers superior performance with lower memory usage:

sudo apt update
sudo apt install nginx

Manage the Nginx service:

sudo systemctl stop nginx
sudo systemctl start nginx
sudo systemctl enable nginx

Verify Nginx installation by accessing http://localhost and confirming the “Welcome to nginx!” message appears.

Step 3: Install and Configure MariaDB Database

MyBB requires a MySQL-compatible database server. MariaDB provides excellent performance and security features for forum applications.

Install MariaDB Server:

sudo apt install mariadb-server mariadb-client

Secure Your Database Installation:

Run the security script to configure initial security settings:

sudo mysql_secure_installation

Follow the prompts to set a root password, remove anonymous users, disable remote root login, and remove test databases.

Create MyBB Database and User:

Access the MariaDB shell and create necessary database components:

sudo mysql -u root -p

Execute the following SQL commands:

CREATE DATABASE mybb_forum CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'mybbuser'@'localhost' IDENTIFIED BY 'strong_password_here';
GRANT ALL PRIVILEGES ON mybb_forum.* TO 'mybbuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Replace strong_password_here with a secure password containing uppercase letters, lowercase letters, numbers, and special characters.

Step 4: Install PHP and Required Extensions

MyBB requires PHP with specific extensions for optimal functionality. Install PHP-FPM and essential modules:

sudo apt install php-fpm php-mysql php-curl php-xml php-gd php-mbstring php-zip php-json php-intl

Configure PHP Settings:

Edit the PHP configuration file to optimize performance:

sudo nano /etc/php/8.3/fpm/php.ini

Adjust these critical settings:

memory_limit = 256M
max_execution_time = 300
upload_max_filesize = 32M
post_max_size = 32M

Restart PHP-FPM to apply changes:

sudo systemctl restart php8.3-fpm

Step 5: Download and Configure MyBB Files

Navigate to the temporary directory and download the latest MyBB release:

cd /tmp
wget https://resources.mybb.com/downloads/mybb_1838.zip

Extract the downloaded files:

sudo unzip mybb_*.zip -d /var/www/mybb

Set Proper Permissions:

Configure file ownership and permissions for security:

sudo chown -R www-data:www-data /var/www/mybb/
sudo chmod -R 755 /var/www/mybb/

The MyBB files are now located in /var/www/mybb/Upload/ directory, which will serve as your web root.

Step 6: Configure Virtual Host

Apache Virtual Host Configuration

Create an Apache virtual host file for your MyBB installation:

sudo nano /etc/apache2/sites-available/mybb.conf

Add the following configuration:

<VirtualHost *:80>
    ServerName mybb.example.com
    ServerAdmin admin@example.com
    DocumentRoot /var/www/mybb/Upload
    
    <Directory /var/www/mybb/Upload/>
        Options FollowSymlinks
        AllowOverride All
        Require all granted
    </Directory>
    
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Enable the virtual host and required modules:

sudo a2ensite mybb.conf
sudo a2enmod rewrite
sudo systemctl restart apache2

Nginx Server Block Configuration

For Nginx users, create a server block configuration:

sudo nano /etc/nginx/sites-available/mybb.conf

Insert the following configuration:

server {
    listen 80;
    listen [::]:80;
    root /var/www/mybb/Upload;
    index index.php;
    server_name mybb.example.com;
    
    access_log /var/log/nginx/example.com.access.log;
    error_log /var/log/nginx/example.com.error.log;
    
    location / {
        try_files $uri $uri/ /index.php?$args;
    }
    
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php8.3-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

Enable the configuration:

sudo ln -s /etc/nginx/sites-available/mybb.conf /etc/nginx/sites-enabled/
sudo systemctl restart nginx.service

Enable the SameSite Cookie Flag setting for additional protection against cross-site request forgery attacks.

Configure SSRF protection by editing your MyBB configuration file:

sudo nano /var/www/mybb/Upload/inc/config.php

Add these security directives:

$config['disallowed_remote_hosts'] = array(
    'localhost',
);

$config['disallowed_remote_addresses'] = array(
    '0.0.0.0',
    '127.0.0.0/8',
    '10.0.0.0/8',
    '172.16.0.0/12',
    '192.168.0.0/16',
);
