Setting up MySQL

toc

MySQL is a core component of Pterodactyl Panel but it can be confusing to setup and use if you've never done so before. This is a very basic tutorial that skims just enough of the surface to set MySQL up and running with the panel. If you're interested in learning more, there are some great tutorials available on the Internet.

Logging In

The first step in this process is to login to the MySQL command line where we will be executing some statements to get things setup. To do so, simply run the command below and provide the Root MySQL account's password that you setup when installing MySQL. If you do not remember doing this, chances are you can just hit enter as no password is set.

mysql -u root -p

Creating a User

For security sake, and due to changes in MySQL 5.7, you'll need to create a new user for the panel. To do so, we want to first tell MySQL to use the mysql database, which stores such information.

Next, we will create a user called pterodactyl and allow logins from localhost which prevents any external connections to our database. You can also use % as a wildcard or enter a numeric IP. We will also set the account password to somePassword.

USE mysql;

# Remember to change 'somePassword' below to be a unique password specific to this account.
CREATE USER 'pterodactyl'@'127.0.0.1' IDENTIFIED BY 'somePassword';

Create a Database

Next, we need to create a database for the panel. In this tutorial we will be naming the database panel, but you can substitute that for whatever name you wish.

CREATE DATABASE panel;

Assigning Permissions

Finally, we need to tell MySQL that our pterodactyl user should have access to the panel database. To do this, simply run the command below. If you plan on also using this MySQL instance as a database host on the Panel you'll want to include the WITH GRANT OPTION (which we are doing here). If you won't be using this user as part of the host setup you can remove that.

GRANT ALL PRIVILEGES ON panel.* TO 'pterodactyl'@'127.0.0.1' WITH GRANT OPTION;
FLUSH PRIVILEGES;

Adding Database to Pterodactyl Panel

In this guide we assume you have successfully installed the panel using the specified MariaDB as your database and it is on the 0.7.15 version.

Adding DB user

First of all you will need to add a user to your database.This is simply done by connecting to your database via ssh and running the following. And entering your database root password, if you haven't set one just hit enter.

mysql -u root -p

Once you are in the database you need to change the db schema by running

USE mysql;

To than create a user run. Changedata and password to keep your database safe!

CREATE USER 'data'@'127.0.0.1' IDENTIFIED BY 'password';

Than add privileges for the user. :::danger If your database is on a different host than your panel/daemon make sure to use % instead of 127.0.0.1 bellow :::

GRANT ALL PRIVILEGES ON *.* TO 'data'@'127.0.0.1' WITH GRANT OPTION;
FLUSH PRIVILEGES;

Close your database connection with

EXIT;

You can now close your ssh session. :::tip Note. You might want to open your database to the internet. This is done by setting it's bind address to 0.0.0.0 instead of 127.0.0.1 :::

Adding the DB to the Panel

Go to yourpaneldomain/admin/databases and click Create New This will open up a window to add a database. Here you will need to fill it out as follows:

Name - A familiar name to reference the db at a later stage.
Host - The server this database is hosted on.
Port - Port of the database server.
Username - Username of the user we created earlier.
Password - Password of the user we created earlier.
Linked node - Node the database is hosted on(can be left as none) Hit create and you are done!

Common Errors

DatabaseController.php:142

production.ERROR: ErrorException: Undefined variable: host in /var/www/pterodactyl/app/Http/Controllers/Admin/DatabaseController.php:142

The database user you are trying to use doesn't have appropriate grants/has used incorrect password.
