Install Simple Machines Forum on a CentOS 7 Linux VPS

smfSimple Machines Forum, also known as SMF is a very popular forum platform which is widely used. It is an open-source software which is written in PHP and uses a MySQL/MariaDB database. It provides many features and it is user-friendly. In this tutorial we will show you how to install Simple Machines Forum 2.0.9 on a Linux VPS.

First of all, make sure that all your system software is up to date. For that purpose you can use the command:

yum -y update

The command will automatically update all your system software to the latest version.

Next, make sure that you have a LAMP stack installed on your VPS. Else, please use our guide about how to install LAMP on CentOS 7. If you have already fulfilled this operation, you are ready to start with the installation of Simple Machines Forum on your CentOS VPS.

As we mentioned before, Simple Machines Forum uses a MySQL/MariaDB database so we need to create a database first, where Simple Machines Forum will store its data. Connect to your VPS via SSH and run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MySQL/MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for the Simple Machines Forum software. Also, you will need to create a database user as well as to set up a new database password. For that purpose you can use the following commands:

CREATE USER 'smf_user'@'localhost' IDENTIFIED BY 'YoUr_PaSsWoRd';
GRANT ALL PRIVILEGES ON `smf`.* TO 'smf_user'@'localhost';

You can replace the name of the database, the database user and the password with values of your choice.

The next step is to download Simple Machines Forum on your CentOS VPS. Navigate to your ‘/var/www/html/’ directory:

cd /var/www/html/

Create a new directory for the Simple Machines Forum files:

mkdir smf

Navigate to that directory:

cd smf/
