Set up MariaDB on macOS (quick)

1. Installing MariaDB Server

Using Homebrew, MariaDB Server can be installed easily:

brew install mariadb

2. Start the server

mysql.server start

You can also configure auto-start using Homebrew's services functionality:

brew services start mariadb

3. Login to the server

After the server is started, you can log in with the user mysql or as root sudo mysql -u root

4. Configure a database

Create a database

After logging into the server with the command above, execute

mysql> CREATE DATABASE your_database_name;

Note, that the ; is mandatory!

Create a user

First create the user for localhost:

mysql> CREATE USER 'app_user'@'localhost' IDENTIFIED BY 'Password123!';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'app_user'@'localhost'
-> WITH GRANT OPTION;

Next, create the user for an arbitrary server:

mysql> CREATE USER 'app_user'@'%' IDENTIFIED BY 'Password123!';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'app_user'@'%'
-> WITH GRANT OPTION;

Good to know
If any of the specified accounts, or any permissions for the specified accounts, already exist, then the server returns ERROR 1396 (HY000). If an error occurs, CREATE USER will still create the accounts that do not result in an error. Only one error is produced for all users which have not been created:

ERROR 1396 (HY000): Operation CREATE USER failed for 'u1'@'%','u2'@'%'

After completing those steps, the database is ready and should also be managable using e.g. DataGrip.
