How To Install Simple Machines Forum on Ubuntu 24.04 or Newer

Welcome back to the Greenhost.cloud blog! Today, we’re diving into the world of online communities by showing you how to install Simple Machines Forum (SMF) on Ubuntu 24.04 or newer. SMF is a powerful, scalable forum software that allows you to create and manage an engaging online community effortlessly. Whether you’re an experienced developer or a beginner, this guide will help you get up and running in no time.

Prerequisites

Before we begin the installation process, ensure you have the following:

1. Ubuntu 24.04 or newer installed on your server.
2. A non-root user with sudo privileges.
3. LAMP stack (Linux, Apache, MySQL, PHP) installed on your server. If you haven’t installed it yet, you can follow these commands to set it up:

   sudo apt update
   sudo apt install apache2 mysql-server php php-mysql libapache2-mod-php php-xml php-mbstring

4. Composer (optional but recommended for managing dependencies).

Step 1: Download Simple Machines Forum

First, navigate to the directory where you want to install SMF. We’ll use the /var/www/html directory for this example.

cd /var/www/html

Next, download the latest version of SMF from the official website. At the time of writing, the latest version is 2.1. This command will download the latest SMF package:

wget https://download.simplemachines.org/index.php/smf_2-1-3_install.zip

Step 2: Unzip the Downloaded Package

Now, you need to unzip the downloaded file. If you don’t have unzip installed, you can install it with the following command:

sudo apt install unzip

After that, unzip the package:

unzip smf_2-1-3_install.zip

This will create a new directory named smf in your current directory.

Step 3: Set Permissions

Setting the appropriate permissions is crucial for the security and functionality of your forum. Change the ownership of the smf directory to the web server user:

sudo chown -R www-data:www-data smf

Set the correct permissions:

sudo find smf -type d -exec chmod 755 {} \;
sudo find smf -type f -exec chmod 644 {} \;

Step 4: Create a MySQL Database

Next, you need to create a database for your Simple Machines Forum. Log in to MySQL with the following command:

sudo mysql -u root -p

Once logged in, create a database and user for SMF:

CREATE DATABASE smf_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'smf_user'@'localhost' IDENTIFIED BY 'your_password_here';
GRANT ALL PRIVILEGES ON smf_db.* TO 'smf_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Make sure to replace your_password_here with a strong password.

Step 5: Configure Apache

To serve your forum, you need to create an Apache configuration file. Create a new file in the /etc/apache2/sites-available/ directory:

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

Add the following configuration:

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/html/smf
    ServerName yourdomain.com

    <Directory /var/www/html/smf>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/smf_error.log
    CustomLog ${APACHE_LOG_DIR}/smf_access.log combined
</VirtualHost>

Make sure to replace yourdomain.com with your actual domain name.

Next, enable the new site and the mod_rewrite module:

sudo a2ensite smf.conf
sudo a2enmod rewrite

Then, restart Apache to apply the changes:

sudo systemctl restart apache2

Step 6: Run the SMF Installation Script

Now, open your web browser and navigate to http://yourdomain.com, you should see the Simple Machines Forum installation wizard. Follow the instructions on the screen:

1. Accept the license agreement.
2. Enter the database details you created earlier (database name, username, and password).
3. Configure the forum settings, such as the site name, email, and other options.

Once you complete the installation, remember to delete the install.php file for security reasons:

sudo rm -rf /var/www/html/smf/install.php
