MyBB is a free and open source, intuitive and extensible forum program. MyBB source code is hosted on GitHub. This guide will show you how to install MyBB forum software on a fresh Fedora 28 IT Web Services instance.


  • PHP version 5.2 or greater
  • MariaDB
  • Nginx, Apache, Lighttpd or IIS web server. This guide will use Nginx.

NOTE: Replace all instances of example.com with your domain name.

Before you begin

Check the Fedora version.

cat /etc/fedora-release
# Fedora release 28 (Twenty Eight)

Create a new non-root user account with sudo access and switch to it.

useradd -c "John Doe" johndoe && passwd johndoe
usermod -aG wheel johndoe
su - johndoe

NOTE: Replace johndoe with your username.

Set up the timezone.

timedatectl list-timezones
sudo timedatectl set-timezone 'Region/City'

Ensure that your system is up to date.

sudo dnf check-upgrade || sudo dnf upgrade -y

Install necessary packages.

sudo dnf install -y wget vim unzip bash-completion

For simplicity, disable SELinux and Firewall.

sudo setenforce 0; sudo systemctl stop firewalld; sudo systemctl disable firewalld

Step 1 – Install PHP

Install PHP, as well as the required PHP extensions.

sudo dnf install -y php-cli php-fpm php-gd php-mbstring php-xml php-mysqlnd php-pgsql php-pdo

Check the version.

php --version
# PHP 7.2.8 (cli) (built: Jul 17 2018 05:35:43) ( NTS )
# Copyright (c) 1997-2018 The PHP Group
# Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

Enable and start PHP-FPM.

sudo systemctl enable php-fpm.service
sudo systemctl start php-fpm.service

Step 2 – Install MariaDB and create a database for MyBB

Install MariaDB database server.

sudo dnf install -y mariadb-server

Check the version.

mysql --version
# mysql  Ver 15.1 Distrib 10.2.16-MariaDB, for Linux (x86_64) using readline 5.1

Enable and start MariaDB.

sudo systemctl enable mariadb.service
sudo systemctl start mariadb.service

Run the mysql_secure_installation script to improve the security of your MariaDB installation.

sudo mysql_secure_installation

Log in to MariaDB as the root user.

mysql -u root -p
# Enter password:

Create a new MariaDB database and user, and remember the credentials.

GRANT ALL ON dbname.* TO 'username' IDENTIFIED BY 'password';

Exit MariaDB.


Step 3 – Install and configure Nginx

MyBB can work with other popular web servers. In this guide we will use Nginx.

Install Nginx.

sudo dnf install -y nginx

Check the version.

nginx -v
# nginx version: nginx/1.12.1

Enable and start Nginx.

sudo systemctl enable nginx.service
sudo systemctl start nginx.service

Configure Nginx. Run sudo vim /etc/nginx/conf.d/mybb.conf and populate it with the following configuration.

server {
  server_name forum.example.com;
  root /var/www/mybb;
  location / {
    index index.php;
  # Deny access to internal files.
  location ~ /(inc|uploads/avatars) {
    deny all;
  location ~ .php$ {
    fastcgi_pass unix:/run/php-fpm/www.sock;
    fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include fastcgi_params;

Test the configuration.

sudo nginx -t

Reload Nginx.

sudo systemctl reload nginx.service

Step 4 – Install MyBB

Create a document root directory.

sudo mkdir -p /var/www/mybb

Change ownership of the /var/www/mybb directory to johndoe.

sudo chown -R johndoe:johndoe /var/www/mybb

Download the latest release of MyBB and unzip it.

cd /var/www/mybb
wget https://resources.mybb.com/downloads/mybb_1817.zip
unzip mybb_1817.zip
mv /var/www/mybb/Upload/* /var/www/mybb

Remove the downloaded .zip file and the Upload folder.

rm mybb_1817.zip
rmdir Upload

Change ownership of the /var/www/mybb directory to nginx.

sudo chown -R nginx:nginx /var/www/mybb

Run sudo vim /etc/php-fpm.d/www.conf and set the user and group to nginx. Initially, it will be set to apache.

sudo vim /etc/php-fpm.d/www.conf
# user = nginx
# group = nginx

Restart PHP-FPM.

sudo systemctl restart php-fpm.service

As the last step, open your domain and follow the installation wizard for MyBB. To access the installer you must navigate to the /install directory of your site in your web browser. For example, if your domain is example.com, and you uploaded your MyBB files to the root directory, navigate to http://example.com/install. After navigating to the MyBB installation location, the MyBB installation wizard page will appear.

To access MyBB admin append /admin to your site URL.

After the installation, you should remove the /install directory from your server to prevent anyone else from running the installation again.

sudo rm -rf /var/www/mybb/install/
