How to install Simple Machines Forum with Apache on Ubuntu 24.04
You install Simple Machines Forum (SMF) with Apache on Ubuntu 24.04 by setting up your web server and database to host the SMF application.
Simple Machines Forum is a free, open-source forum software that helps you build online communities with a feature-rich and user-friendly interface.
This process involves configuring Apache to serve your SMF files and setting up a MySQL or MariaDB database for SMF to store all your forum data. You’ll be working with Ubuntu 24.04, the latest LTS release, ensuring a stable platform for your new forum.
Install Apache and MariaDB servers using apt, then create a database and user for SMF. Download the SMF package, extract it to your web root, and run the installer script.
Install Apache HTTP server on Ubuntu
Apache is a popular web server that works well with Ubuntu 24.04, and you’ll need it to run your Simple Machines Forum.
To do that, open the Ubuntu terminal and run the commands below to install the Apache web server.
sudo apt update
sudo apt install apache2
Once Apache is installed, the commands below can start, stop, and enable the Apache web server to start automatically when your server boots up.
sudo systemctl stop apache2
sudo systemctl start apache2
sudo systemctl enable apache2
You can test that the Apache web server is running by opening your web browser and browsing to the server’s localhost or IP address.
http://localhost

When you see the Apache2 Default Page, it means the Apache HTTP server is successfully installed.

Install the MariaDB database server on Ubuntu
Your Simple Machines Forum needs a database to keep all its information safe, and MariaDB is a solid choice for Ubuntu.
To install and use the MariaDB database server, use the instructions below.
Open the Ubuntu terminal and run the commands below to install the MariaDB database server.
sudo apt update sudo apt install mariadb-server
Once the MariaDB database server is installed, use the commands below to stop, start, and enable the MariaDB server to start automatically when the server boots.
sudo systemctl stop mariadb sudo systemctl start mariadb sudo systemctl enable mariadb
Run the following commands to validate and test if the MariaDB database server is installed successfully.
sudo mariadb
Once you run the commands above, it will log you onto the MariaDB console and display a message similar to the one below.
Welcome to the MariaDB monitor. Commands end with ; or g. Your MariaDB connection id is 32 Server version: 10.11.2-MariaDB-1 Ubuntu 23.04 Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or 'h' for help. Type 'c' to clear the current input statement. MariaDB [(none)]>
The message tells you that the server is installed successfully.

Create an SMF database
Now that MariaDB is set up, you need to create a special database for your Simple Machines Forum, which we’ll call ‘smfdb’, and give it a user.
As part of the setup, we will create a smfdb database and a user account called smfdbuser.
Finally, we’ll grant the smfdbuser full access to the smfdb database.
All the database steps above can be done using the commands below:
But first, log on to the MariaDB database server:
sudo mariadb
Then run the commands below to complete the steps:
CREATE DATABASE smfdb CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
CREATE USER smfdbuser@localhost IDENTIFIED BY 'type_your_password_here';
GRANT ALL ON smfdb.* TO smfdbuser@localhost WITH GRANT OPTION;
FLUSH PRIVILEGES;
exit
Ensure to replace ‘type_your_password_here ‘with your password.
Install PHP on Ubuntu Linux
Simple Machines Forum is built with PHP, so you must install it on your Ubuntu system before you can get your forum working.
Then, run the commands below to install the latest PHP version.
sudo apt install php libapache2-mod-php php-intl php-mysql php-curl php-cli php-zip php-xml php-gd php-common php-mbstring php-xmlrpc php-bcmath php-json php-sqlite3 php-soap php-zip

Download SMF files
It’s time to get the Simple Machines Forum software by downloading the latest files and getting them ready to install on your Ubuntu server.
To always install the latest version, check the download page for SMF. If a new version is available, replace the version number in the link below.
First, navigate to the /tmp/ directory and download SMF files. After unzipping the file, move the content into the SMF folder in the Apache root directory.
The final step is to change the permissions. This will allow the Apache web server to interact safely with the files, ensuring a secure environment for your SMF installation.
cd /tmp/
wget https://download.simplemachines.org/index.php/smf_2-1-4_install.zip
sudo mkdir -p /var/www/smf/
sudo unzip smf*_install.zip -d /var/www/smf/
sudo chown -R www-data:www-data /var/www/smf/
Once you have completed all the above steps, continue configuring the Apache web server below to serve the SMF content.
Run the commands below to create an Apache virtual host file for SMF.
sudo nano /etc/apache2/sites-available/smf.conf
Then, copy and paste the content block below into the Apache server block.
<VirtualHost *:80>
ServerName smf.example.com
ServerAlias www.smf.example.com
ServerAdmin admin@example.com
DocumentRoot /var/www/smf
<Directory /var/www/smf/>
Options FollowSymlinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Save the file.
Then, run the commands below to enable the virtual host and restart the Apache server.
sudo a2ensite smf.conf
sudo a2enmod rewrite
sudo systemctl restart apache2
