In the following tutorial I will explain how to install MyBB 1.8.12 on Ubuntu Server. I will be doing this from the command line so no GUI needed.

  1. Download the MyBB package. You will want to get the latest version of MyBB.
  2. wget --content-disposition https://www.mybb.com/download/latest -O mybb.zip
    
  3. By default Ubuntu does not come with unzip. Install that now.
  4. sudo apt install unzip
    
  5. Unzip the MyBB zip file
  6. unzip mybb.zip
    

    2 folders should now be in your present working directory. Unload and Documentation.

  7. Install LAMP (Linux, Apache2, PHP and MySQL) Restart Apache after
  8. sudo apt install apache2 mysql-server php-mysql php libapache2-mod-php php-mcrypt
    sudo systemctl restart apache2
    

    This install will ask to create a root password for the MySQL database.

  9. Move MyBB files to the server folder
  10. cd /var/www/
    sudo mkdir mybb/
    mv ~/Upload/* /var/www/html/mybb/
    

    You should now see all the files in the www/mybb directory.

  11. Rename the inc/config.default.php
  12. sudo mv inc/config.default.php inc/config.php
    
  13. Now change permissions on the following files and directories
  14. sudo chmod 666 inc/config.php inc/settings.php inc/languages/english/*.php inc/languages/english/admin/*.php
    sudo chmod 777 cache/ cache/themes/ uploads/ uploads/avatars/ admin/backups/
    
  15. Login to MySQL and create Database.
  16. mysql -u root -p
    

    Enter the password that was create for MySQL.
    Now create the database and a user to have access to this database only.

    create database MyBB;
    grant all privileges on MyBB.* to 'MyBB'@'localhost' identified by "S0mePassw0rd";
    flush privileges;
    exit;
    
  17. Browse to the install page.
  18. You can now follow the step by step installer. Be sure to specify the database credentials you create above. Do not use the root account.
