In this article, I am going to show you how to create a new MySQL/MariaDB database, create a new MySQL/MariaDB user, and grant the new user access to the newly created database.
Connect to the Database
To access the MySQL/MariaDB server as root user, run the command below. When prompted, type in your MySQL root password and press <Enter>.
sudo mysql -u root -p
NOTE: If you haven’t setup a MySQL/MariaDB root password, just press <Enter> when prompted for the password.
Create a new MySQL/MariaDB Database
To create a new database magento_dev (let’s say), run the following SQL statement:
mysql> CREATE DATABASE magento_dev;
If you want to create a MySQL/MariaDB database that uses a specific character set and collation, check this article.
Create a New MySQL/MariaDB User
To create a new MySQL/MariaDB database user magento_dev and set the password ohf3zieN, run the following SQL statement:
mysql> CREATE USER 'magento_dev'@'localhost' IDENTIFIED BY 'ohf3zieN';
If you want to allow remote database access to the magento_dev user, run the following SQL statement instead:
mysql> CREATE USER 'magento_dev'@'%' IDENTIFIED BY 'ohf3zieN';
Allow MySQL/MariaDB User Access to Database
To grant the user magento_dev all type of privileges/access to the database magento_dev, run the following SQL statement:
mysql> GRANT ALL PRIVILEGES ON magento_dev.* TO 'magento_dev'@'localhost';
If you’re created a remote database user, run the following SQL statement instead:
mysql> GRANT ALL PRIVILEGES ON magento_dev.* TO 'magento_dev'@'%';
Reload MySQL/MariaDB Privileges
After granting the magento_dev user access to the magento_dev database, you must reload the MySQL/MariaDB privileges to apply the changes.
To reload the MySQL/MariaDB privileges, run the following SQL statement:
mysql> FLUSH PRIVILEGES;
