A word of warning: Given the current state of attacks, across the landscape of IT, I highly recommend you using seriously strong passwords for your databases. Use a random password generator and then store that in a password manager (instead of using an easily memorized password). Be safer than safe.

With that said, let's get to work.

Setting the password for the first time

Do note, throughout this article, I will refer to MySQL, with the idea that everything will work for both MySQL and MariaDB.

Typically, during the installation of MySQL and MariaDB, you are asked to set an initial password. If, for whatever reason that didn't happen, you will need to set a password for the first time. To do that, open up a terminal window and issue the following command:

Where NEWPASSWORD is the password to be used. Now, when you log into MySQL, with the command mysql -u root -p, you will be prompted to enter the newly configured password.

An alternative method for setting the root password for the first time, one that also adds a bit of security to your MySQL database, is to use the mysql_secure_connection command. Not only will this command set the root user password, but it will allow you to remove anonymous users, disallow remote root login, and remove the test database. To use this command, simply type:

Answer the presented questions and your password will be set (as well as your database being a bit more secure).

2. Start the MySQL server with the command sudo mysqld_safe —skip-grant-tables —skip-networking &
3. Connect to the MySQL server as the root user with the command mysql -u root

A second warning

Just to be certain, I wanted to remind you how important it is to set a very difficult password for the MySQL root user. Those databases hold sensitive information, so the last thing you need is to make use of a weak password that can be easily cracked. Use a long password that you cannot memorize and store it in a password vault. You'll be glad you did.
