Secure MariaDB

Once you have created a new database and user for your application, connect to your MariaDB server and follow these recommendations:

• Remove anonymous users:

  MariaDB> DELETE FROM mysql.user WHERE User='';
  

• Remove the test database and access to it:

  MariaDB> DROP DATABASE test;
  MariaDB> DELETE FROM mysql.db WHERE Db='test' OR Db='test\\_%';
  

• Disallow root login remotely:

  MariaDB> DELETE FROM mysql.user WHERE User='root' AND Host NOT IN ('localhost', '127.0.0.1', '::1');
  

  Don’t forget to reload the privileges tables to apply the changes:

  MariaDB> FLUSH PRIVILEGES;
  

• Change your root user password.

• It is strongly recommended that you do not have empty passwords for any user accounts when using the server for any production work.

• If you don’t need remote access, uncomment the line

  #bind-address=127.0.0.1
  

  in the MariaDB configuration file to only listen for connections on the local machine. Restart the server once done.
