Mysql User Creation: Setting Up a New MySQL User Account

Posted on in Categories , , , last updated May 3, 2017

How do I create a user account on MySQL database server?

When you try to access MySQL database server from client such as mysql or even programming language such as php or perl you need a user account. MySQL has sophisticated user management system that controls who can access server and from which client system. It uses special tables in mysql database. In order to create a new user account you need a MySQL root account password. You need to use the GRANT SQL command to set up the MySQL user account. Finally, use the account’s name and password to make connections to the MySQL server.

Please note that MySQL root user account is different from UNIX/Linux root login account. For example, the MySQL root user and the Linux/Unix root user are separate and have nothing to do with each other, even though the username is the same in each case.

Setup a root user password

To setup root password for first time, use mysqladmin command at shell prompt as follows:
$ mysqladmin -u root password NEWPASSWO
If you want to change or update a root user password, then you need to use the following command:
$ mysqladmin -u root -p'oldpassword' password newpass

Procedure for setting up a MySQL user account

Login in as mysql root user. At shell prompt type the following command:

$ mysql -u root -p

OR

$ mysql -u root -h your-mysql-server-host-name -p

Create a new mysql database called demo. Type the following command at mysql> prompt:

mysql> CREATE DATABASE demo;

Create a new user called user1 for database called demo:

mysql> GRANT ALL ON demo.* TO user1@localhost IDENTIFIED BY 'mypassword';

How do I connect to MySQL database demo using user1 account?

User user1 can connect to demo database using the following shell command:

$ mysql -u user1 -p demo

OR

$ mysql -u user1 -h  your-mysql-server-host-name-here -p demo

Where,

  • -u user1 : MySQL Username
  • -h : MySQL server name (default is localhost)
  • -p : Prompt for password
  • demo: demo is name of mysql database (optional)

  1. Hi I am new to mysql,
    When I try to connect from command line. I need to enter my root password. I have created the demo database, but when I type “mysql -u user1 -p demo”, It shows me ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
    corresponds to your MySQL server version for the right syntax to use near ‘mysql
    -u user1 -p demo’ at line 1. Please help, how can I connect with this user1 to demo database in command prompt.

    1. you need to grant the privilege of operating the database’demo’ to the user in the root model, like this: grant all on demo(name of your database) to user1(username)@ “localhost ” identified by “password”(your account’s password).
