Setting up MySQL

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'@'' 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.


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.



The following is to add a database managed by the panel for its game servers

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 CLI and running the following commands. You may need to enter a password if you specified one when connecting to the database. To connect to your database, enter:

mysql -u root -p

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

USE mysql;

To then create a user run. Change data and password to keep your database safe!

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

Then add privileges for the user.


If your database is on a different host than the one where your panel(daemon is installed, make sure to use % instead of below


Close your database connection with


You can now close your ssh session.


Note. You might want to open your database to the internet. This is done by setting its bind-address to instead of

Adding the DB to the Panel

Go to yourpaneldomain/admin/databases and click Create New. This will open up a window in which you can add a database. Fill the form, following this example:

  • 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. (Default value can be retained) Hit create and you are done!

Common Errors


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.
