Understand the default MariaDB configuration

Before running the commands shown on this page, you should load the Bitnami stack environment by executing the installdir/use_APPNAME script (Linux and MacOS) or by clicking the shortcut in the Start Menu under “Start -> Bitnami APPNAME Stack -> Application console” (Windows). On OS X VMs, the installation directory is /opt/bitnami and OS X VM users can click the “Open Terminal” button to run commands. Learn more about the Bitnami stack environment and about OS X VMs.

The grant tables define the initial MariaDB user accounts and their access privileges. The default configuration consists of:

  • A privileged account with a username of root. The root user has remote access to the database.
  • An anonymous user without remote access to the database server. This user can only connect from the local machine and it is only intended for testing.
  • A test database only intended for testing.

Check our recommendations for a production server.

MariaDB version

In order to see which MariaDB version are your machine running you can execute the following command:

$ mysqld --version

MariaDB configuration file

The MariaDB official documentation has more details about how to configure the MariaDB database.

MariaDB socket

On Unix, MariaDB clients can connect to the server in the local machine using an Unix socket file at installdir/mariadb/tmp/mysql.sock.

MariaDB port

The default port for MariaDB is 3306.

MariaDB Process Identification Number

The MariaDB .pid file allows other programs to find out the PID (Process Identification Number) of a running script. Find it at installdir/mariadb/data/

MariaDB log file

The log-error file contains information indicating when MariaDB was started and stopped and also any critical errors that occur while the server is running. If MariaDB notices a table that needs to be automatically checked or repaired, it writes a message to the error log. Find it at installdir/mariadb/data/mysqld.log.
