** How to Create a New User
CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';
newuser has no permissions to access any databases nor to login to MySQL shell.
Provide access to new user:
GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';
The asterisks in this command refer to the database and table (respectively) that they can access—this specific command allows to the user to read, edit, execute and perform all tasks across all the databases and tables.
Once you have finalized the permissions that you want to set up for your new users, always be sure to reload all the privileges.
FLUSH PRIVILEGES;
Your changes will now be in effect.
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 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
To provide a specific user with a permission, you can use this framework:
GRANT [type of permission] ON [database name].[table name] TO ‘[username]’@'localhost’;
