Understand the default MariaDB configuration

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.

MariaDB socket

On Unix, MariaDB clients can connect to the server in the local machine using an Unix socket file at /opt/bitnami/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 /opt/bitnami/mariadb/data/mysqld.pid.

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 /opt/bitnami/mariadb/data/mysqld.log.
