How-to create a MySQL database and assign user privileges to it

NOTE: Please note that this is done in the Command Line Interface.

First login to the mySql server using root.
```
mysql -uroot -pROOT_PASSWORD
```
Replace ROOT_PASSWORD with the password for the root user.
Once logged in we create a new database called TEST_DB replace with your database name
```
create database TESTDB;
Query OK, 1 row affected (0.00 sec)
```
We grant access privileges to user MYUSER to connect to the mysql server from localhost using the password MYPASSWORD
```
grant usage on *.* to MYUSER@localhost identified by 'MYPASSWORD';
Query OK, 0 rows affected (0.00 sec)
```

Now we grant all privileges to MYUSER on the database TESTDB

grant all privileges on TESTDB.* to MYUSER@localhost ;
Query OK, 0 rows affected (0.00 sec)

Type exit to log out
```
exit;
```
Now you can login to TESTDB using user MYUSER and password MYPASSWORD
```
mysql -u MYUSER -p'MYPASSWORD' TESTDB
```
