Normally while installing MySQL/MariaDB database server on Linux, it’s recommended to set a MySQL root user password to secure it, and this password is required to access the database server with root user privileges.

In this guide, we will show you how to connect and run MySQL commands without entering a password (mysql passwordless root login) on the Linux terminal.

How to Set MySQL Root Password

In case you have freshly installed the MySQL/MariaDB server, then it doesn’t require any password to connect to it as root user. To secure it, set the MySQL/MariaDB password for root user with the following command.

Note that this command is just one of the many MySQL (Mysqladmin) Commands for Database Administration in Linux.

# mysqladmin -u root password YOURNEWPASSWORD

How to Connect or Run MySQL Without Root Password

To run MySQL commands without entering password on the terminal, you can store your user and password in the ~/.my.cnf user specific configuration file in user’s home directory as described below.

Now create the config file ~/.my.cnf and add configurations below in it (remember to replace mysqluser and mysqlpasswd with your own values).

[mysql]
user=user
password=password

Save and close the file. Then set the suitable permissions on it, to make it only readable and writable by you.

# chmod 0600 .my.cnf

Once you have set user and password in the Mysql configuration file, from now on when you run mysql commands such as mysql, mysqladmin etc, they will read the mysqluser and mysqlpasswd from the above file.

# mysql 
# mysql -u root
