NOTE: We are in the process of modifying the configuration for many Bitnami stacks. On account of these changes, the file paths and commands stated in this guide may change depending on whether your Bitnami stack uses MySQL or MariaDB. To identify which database server is used in your stack, run the command below:
$ test -d /opt/bitnami/mariadb && echo "MariaDB" || echo "MySQL"
The output of the command indicates which database server (MySQL or MariaDB) is used by the installation, and will allow you to identify which guides to follow in our documentation for common database-related operations.
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:
IMPORTANT: Please ensure the mysql.user table includes a ‘root’@‘localhost’ entry. Otherwise, you will lose admin access to the database when running the next command
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;
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
in the MariaDB configuration file to only listen for connections on the local machine. Restart the server once done.
