MySQL is one of the most popular database management systems. In this tutorial we will cover the steps needed to create new MySQL user and grant permissions to it in CentOS 6.4, Debian or Ubuntu platform.


    • CentOS 6.4, Debian or Ubuntu installed on your computer/server
    • SSH access (Command line access to the server)
    • root privileges
    • Basic skills for working on a Linux environment
    • LAMP installed on the server

All operation will be executed inside a MySQL prompt with the root user:

You will be prompted to fill in the MySQL root password.

Create a new user

We can create new MySQL user with the following command:


      • user – the name of the MySQL user which will be created
      • password – the password which we want to assign to that user

All MySQL commands are engin with a semicolon (;).

Grant permissions for a user

The next thing that we will have to do is to grant privileges for that user in order to be able to access the MySQL client and to work with the corresponding database/s:


      • database – the name of the MySQL database to which we grant access
      • table – the name of the database table to which we grant access

We are allowed to use the asterisk wildcard symbol (*) when we want to grant access to all databases/tables:


With the first command we grant all privileges to the MySQL user to all database tables related to the database with name "database".
In the second case access for the user is granted to all databases.

Here is a list of the MySQL privileges which are most commonly used:

      • ALL PRIVILEGES – grants all privileges to the MySQL user
      • CREATE – allows the user to create databases and tables
      • DROP - allows the user to drop databases and tables
      • DELETE - allows the user to delete rows from specific MySQL table
      • INSERT - allows the user to insert rows into specific MySQL table
      • SELECT – allows the user to read the database
      • UPDATE - allows the user to update table rows

Here is a sample syntax where only two privileges are granted for the user:

In order for the changes to take effect and the privileges to be saved the following command should be executed at the end:

Remove an existing MySQL user

A MySQL user can be deleted with the following command:
