Adding MySQL users

Create an account roughly divided into:

 

 

 Create a user on MySQL:

MariaDB [(none)]> create user first@"localhost" identified by "123456";
Query OK, 0 rows affected (0.001 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.000 sec)

 

  Delete users on MySQL:

MariaDB [(none)]> Delete FROM mysql.user Where User='first' and Host='localhost';
Query OK, 1 row affected (0.000 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.000 sec)
