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 FreeBSD 12 Rcs instance.

Requirements

• PHP, at least version 5.2
• MySQL, at least version 5.0
• Nginx
• The following PHP extensions:
• SimpleXML
• mbstring
• gd
• The respective vendor-specific database PHP extension

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

Before you begin

Check the FreeBSD version.

uname -ro
# FreeBSD 12.0-RELEASE

Ensure that your FreeBSD system is up to date.

freebsd-update fetch install
pkg update && pkg upgrade -y

Install the necessary packages.

pkg install -y sudo vim unzip curl wget bash socat git

Create a new user account with your preferred username. We will use johndoe.

adduser

# Username: johndoe
# Full name: John Doe
# Uid (Leave empty for default): <Enter>
# Login group [johndoe]: <Enter>
# Login group is johndoe. Invite johndoe into other groups? []: wheel
# Login class [default]: <Enter>
# Shell (sh csh tcsh nologin) [sh]: bash
# Home directory [/home/johndoe]: <Enter>
# Home directory permissions (Leave empty for default): <Enter>
# Use password-based authentication? [yes]: <Enter>
# Use an empty password? (yes/no) [no]: <Enter>
# Use a random password? (yes/no) [no]: <Enter>
# Enter password: your_secure_password
# Enter password again: your_secure_password
# Lock out the account after creation? [no]: <Enter>
# OK? (yes/no): yes
# Add another user? (yes/no): no
# Goodbye!

Run the visudo command and uncomment the %wheel ALL=(ALL) ALL line, to allow members of the wheel group to execute any command.

visudo

# Uncomment by removing hash (#) sign
# %wheel ALL=(ALL) ALL

Now, switch to your newly created user with su.

su - johndoe

NOTE: Replace johndoe with your username.

Set up the timezone.

sudo tzsetup

Step 1 - Install PHP and required PHP extensions

Install PHP, as well as the necessary PHP extensions.

sudo pkg install -y php72 php72-mbstring php72-tokenizer php72-pdo php72-pdo_mysql php72-openssl php72-hash php72-json php72-phar php72-filter php72-zlib php72-dom php72-xml php72-xmlwriter php72-xmlreader php72-pecl-imagick php72-curl php72-session php72-ctype php72-iconv php72-gd php72-simplexml php72-zip php72-filter php72-tokenizer php72-calendar php72-fileinfo php72-intl php72-phar php72-soap php72-xmlrpc php72-opcache php72-mysqli php72-bcmath php72-gmp

Check the version.

php --version

# PHP 7.2.19 (cli) (built: Jun 20 2019 01:25:01) ( NTS )
# Copyright (c) 1997-2018 The PHP Group
# Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

Soft-link php.ini-production to php.ini.

sudo ln -s /usr/local/etc/php.ini-production /usr/local/etc/php.ini

Enable and start PHP-FPM.

sudo sysrc php_fpm_enable=yes
sudo service php-fpm start

Step 2 - Install MariaDB and create a database for MyBB

Install MariaDB.

sudo pkg install -y mariadb102-client mariadb102-server

Check the version.

mysql --version
# mysql  Ver 15.1 Distrib 10.2.24-MariaDB, for FreeBSD12.0 (amd64) using readline 5.1

Start and enable MariaDB.

sudo sysrc mysql_enable="yes" 
sudo service mysql-server start

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

sudo mysql_secure_installation

Log into MariaDB as the root user.

mysql -u root -p
# Enter password:

Create a new MariaDB database and user. Remember the credentials for this new user.

CREATE DATABASE dbname;
GRANT ALL ON dbname.* TO 'username' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
exit;

Step 3 - Install and configure Nginx

Install Nginx.

sudo pkg install -y nginx

Check the version.

nginx -v
# nginx version: nginx/1.14.2

Enable and start Nginx.

sudo sysrc nginx_enable=yes
sudo service nginx start

Run sudo vim /usr/local/etc/nginx/mybb.conf and set up Nginx for MyBB.

server {

  listen 80;
  listen [::]:80;
  server_name example.com;
  root /usr/local/www/mybb;

  index index.php;

  location / {
    try_files $uri $uri/ /index.php?$args;
  }
  
  location ~ /(inc|uploads/avatars) {
    deny all;
  }

  location ~ \.php$ {
    try_files $uri =404;
    include fastcgi_params;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_pass 127.0.0.1:9000;
  }

}

Save the file and exit.

Now we need to include mybb.conf in the main nginx.conf file.

Run sudo vim /usr/local/etc/nginx/nginx.conf and add the following line to the http {} block.

include mybb.conf;

Test the configuration.

sudo nginx -t

Reload Nginx.

sudo service nginx reload

Step 4 - Install MyBB

Create a document root directory.

sudo mkdir -p /usr/local/www/mybb

Change ownership of the /usr/local/www/mybb directory to johndoe.

sudo chown -R johndoe:johndoe /usr/local/www/mybb

Download the latest release of MyBB and unzip it.

cd /usr/local/www/mybb
wget https://resources.mybb.com/downloads/mybb_1821.zip
unzip mybb_1821.zip
mv /usr/local/www/mybb/Upload/* /usr/local/www/mybb

Remove the downloaded .zip file.

rm mybb_1821.zip
rmdir Upload

Change ownership of the /usr/local/www/mybb directory to www.

sudo chown -R www:www /usr/local/www/mybb

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 then navigate to http://example.com/install. To access MyBB admin, append /admin to your site URL. You have successfully installed your MyBB.

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

sudo rm -rf /usr/local/www/mybb/install/
