How to Create a New User mysql

  1. mysql  >CREATE USER ‘newuser’@’localhost’ IDENTIFIED BY ‘password’;
  2. mysql> GRANT ALL PRIVILEGES ON * . * TO ‘newuser’@’localhost’;
  3. mysql> FLUSH PRIVILEGES;

How To Grant Different User Permissions

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 full access to a designated database (or if no database is selected, global access 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

To provide a specific user with a permission, you can use this framework:

mysql> GRANT type_of_permission ON database_name.table_name TO ‘username’@’localhost’;

If you want to give them access to any database or to any table, make sure to put an asterisk (*) in the place of the database name or table name.

Each time you update or change a permission be sure to use the Flush Privileges command.

If you need to revoke a permission, the structure is almost identical to granting it:

mysql> REVOKE type_of_permission ON database_name.table_name FROM ‘username’@’localhost’;

Note that when revoking permissions, the syntax requires that you use FROM, instead of TO as we used when granting permissions.

You can review a user’s current permissions by running the following:

mysql> SHOW GRANTS FOR ‘username’@’localhost’;

Just as you can delete databases with DROP, you can use DROP to delete a user altogether:

mysql> DROP USER ‘username’@’localhost’;

To test out your new user, log out by typing:

mysql> quit
