MySQL Commands

1: Login

$ mysql -u user_name -p
Enter password:

2: Create a database

mysql> create database db_name;
Query OK, 1 row affected (0.00 sec)

3: Create a user

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';

4: Grant the privileges to a user

GRANT ALL PRIVILEGES ON db_name . * TO 'newuser'@'localhost';

Here is a short list of other common possible permissions that users can enjoy.

• ALL PRIVILEGES- as we saw previously, this would allow a MySQL user all access to a designated database (or if no database is selected, across the system)
• CREATE- allows them to create new tables or databases
• DROP- allows them to them to delete tables or databases
• DELETE- allows them to delete rows from tables
• INSERT- allows them to insert rows into tables
• SELECT- allows them to use the Select command to read through databases
• UPDATE- allow them to update table rows
• GRANT OPTION- allows them to grant or remove other users' privileges

5: Reload privileges (e.g., once you have finalized the permissions that you want to set up for your new users)

FLUSH PRIVILEGES;

6: Revoke a permission

REVOKE [type of permission] ON [database name].[table name] FROM ‘[username]’@‘localhost’;

7: Delete a user

DROP USER ‘demo’@‘localhost’;

8: Delete a database

DROP DATABASE ‘demo’@‘localhost’;
