Securing MariaDB 10.8

MariaDB comes with a default security script, mysql_secure_installation that is used to improve the security of MariaDB installation by:

  • Setting the password for root accounts (if need be).
  • Disabling remote root login to the databases.
  • Removing anonymous-user accounts.
  • Removing the test database, which by default can be accessed by anonymous users.

Simply run the command below to launch the script.

mysql_secure_installation

MariaDB Authentication

The new installations of MariaDB have two secure accounts are created during the installation.

The accounts are [email protected] and [email protected].

Both accounts uses either of the unix_socket and the mysql_native_password authentication plugins.

unix_socket authentication plugin allows a system root user or a user with sudo rights to login as [email protected] to MariaDB database without a password.

With unix_socket authentication plugin, while being a root user, you can simply login by running either of the commands below;

mysql

or

mysql -u root

Even if you run, mysql -u root -p, and press ENTER for blank password, you will still login.

As a user with sudo rights, prefix the commands above with sudo.

Enable MariaDB password Authentication (this doesnt disable passwordless authentication for root and sudo user)

The mysql_native_password plugin is used as a failover for the unix_socket plugin. However, the account has an invalid password. To enable password authentication, you need to login to MariaDB as root user as shown above and set the password.

mysql
set password = password("[email protected]");
flush privileges;
quit

This re-enables the MariaDB password authentication and hence, you can now login as non root or non sudo user.

[email protected]:~$ mysql -u root -p
Enter password: ENTER PASSWORD
Welcome to the MariaDB monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>

Similarly, you can login as mysql user;

sudo -u mysql mysql

Set Native Password Authentication Method as Default

To completely disable unix_socket authentication plugin and instead use the msqyl_native_password authentication method, simply login to MariaDB and change the authentication plugin for root user.

mysql
ALTER USER [email protected] IDENTIFIED VIA mysql_native_password USING PASSWORD("MyPQQSSword");
flush privileges;
quit

Next time you try to login without specifying the password, login will fail.

sudo mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
