Automatically Create a MySQL Database

Preparing the server

  • Install the MySQL server on your server.
  • Install phpMyAdmin if you want to provide a way to manage the database.

Configure the game

Create variables

  • Configure variables for the MySQL user and password. Go to Settings > Global Variables or Settings > Games > Select the game > Variables. Create 2 new variables:
    • Name: MySQLUser
    • Preserve value: Checked
    • Name: MySQLPassword
    • Preserve value: Checked

Create the scripts

  • Go to Settings > Global Scripts or Settings > Games > Select the game > Custom Scripts. Add the following scripts. They will create the database and user when the service is created and delete them when the service is deleted. Make sure you update the value of mysql_password in all of the scripts.
  • If you are using MySQL 8 remove the MySQL 5 command and uncomment the MySQL 8 commands.
  • These scripts work without any additional changes if MySQL is installed on all servers (master and remotes). If you have a single MySQL server where all remotes connect you will have to change user@localhost to user@% in the user commands and configure your root user to allow connections from all IPs.

Create the custom link to phpMyadmin

  • If you installed phpMyAdmin you can create a custom link. Go back to the game's main settings. Click on the Custom Links icon. Add a new link with these values:
    • Name: phpMyAdmin
    • Description: Manage your database with phpMyAdmin
    • Url: http://$[Service.IpHostname]/phpMyAdmin/index.php?pma_username=![MySQLUser]&pma_password=![MySQLPassword] (you can also use https://phpmyadmin.tcadmin.com)
    • Icon URL: ~/App_Themes/Default/Images/ControlPanel/MenuIcons/Base/Database.png
    • Open in a new window: Checked

UPDATE: Newer phpMyAdmin versions don't allow logging in to mysql with the username/password in the url. https://www.phpmyadmin.net/files/4.9.0.1/

Using the MySQL variables in templates

You can use the following variables in your mail and config file templates:

  •  ![MySQLUser]
  •  ![MySQLPassword]

Optional scripts

Icon to Change MySQL Password

Create a variable named NewMySQLPassword. with:

  • These options checked: "Script parameter", "Save script parameter value", "Admin access", "Sub admin access", "Reseller access", "User access", "Server owner access", "Value is required"
  • Label=New Password
