In order to manipulate users and privileges from users in MySQL you will need to access the MySQL console as root/admin or an user with elevated privileges:
# Start MySQL console as root user and prompt for password mysql -u root -p
This will start the console as the root user to execute queries from the CLI. Here you will able to grant access to any database to other users using the queries that we've wrote in this article.
1. Create database
Initially, you need a database to grant permissions on, so in case that you don't have any or you're learning, create a database using the following statement:
create database MyDatabase;
In this case the name of our database is
2. Grant usage to user with password
As next you need to allow the access to the database, that in our case is
MyDatabase to an user, which in this case is
MyDatabaseUsername and is identified with
grant usage on *.* to MyDatabaseUsername@localhost identified by 'MyPassword';
3. Grant all privileges to database for user
Finally grant all privileges for the database to the previously granted user:
grant all privileges on MyDatabase.* to MyDatabaseUsername@localhost;
Now you should be able to access the database with the specified user in MySQL (in PHP applications etc).
Happy coding !
