Allow linux root user mysql root access without password

Solution 1:

The easiest way to do this is to use a client section of the ~/.my.cnf file, and add the credentials there.


it's a good idea to make that file readable only by root too.

Solution 2:

For mysql 5.7+, if you set empty password for the initial setup, mysql will automatically use auth_socket as a strategy. An attempt to update password without change the strategy will have no result. You can always able to login without using password if your user is root.

Solution Run following command to change the authentication strategy and set the password

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY ''


Solution 3:

As of MySQL 5.6.6, you can use the mysql_config_editor to create an encrypted file that will log you in automatically:

mysql_config_editor set --login-path=client --host=localhost --user=root --password

Then enter the password when prompted.

Note: if your password has '#' in it, and possibly other characters, use single quotes when entering the password.
