MySQL via Command Line 101: Basic Database Interaction
- These instructions are intended for creating a MySQL user on Linux via the command line.
- I’ll be working from a Liquid Web Core Managed CentOS 6.5 server, and I’ll be logged in as root.
Login to MySQL
First we’ll login to the MySQL server from the command line with the following command:
mysql -u root -p
In this case, I’ve specified the user
If you need to change your root (or any other) password in the database, then follow this tutorial on changing a password for MySQL via the command line.
You should now be at a MySQL prompt that looks very similar to this:
Create MySQL User
We’ll create a user with the name
CREATE USER 'testuser'@'localhost' IDENTIFIED BY 'test123test!';
That’s it, congratulations! In just one command you’ve created your first MySQL user. However, this user won’t be able to do anything with MySQL until they are granted additional privileges. In fact, they won’t even be able to login without additional permissions.
To give the new user proper permissions, work through our tutorial on granting permissions to MySQL user’s via the command line.
View a List of MySQL Users
Viewing a full list of MySQL users, including the host they’re associated with, can be done with the following select statement:
SELECT User,Host FROM mysql.user;
