Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf /.my.cnf
This page lists the different mysqld startup options you can use.
mysqld reads the following my.cnf sections: [mysqld] [server] [mysqld-5.1].
In addition MariaDB 5.1 also reads the sections: [mariadb] [mariadb-5.1].
The 5.1 stands for the main version, the above is for MariaDB 5.1.
MariaDB 5.3 also reads the sections [client-server] [mariadb-5.3]
For a full list of mysqld options and their current values (based on your local my.cnf), do:
mysqld --help --verbose

Minimal my.cnf file
Here is a minimal my.cnf file you can install in ~/.my.cnf to test MariaDB 5.3. (For 5.2, you need to copy the section [client-server] to [client] and [mysqld]).
[client-server] # Uncomment these if you want to use a nonstandard connection to MariaDB #socket=/tmp/mysql.sock #port=3306 # This will be passed to all MariaDB clients [client] #password=my_password # The MariaDB server [mysqld] # Directory where you want to put your data data=/usr/local/mysql/var # Directory for the errmsg.sys file in the language you want to use language=/usr/local/mysql/share/mysql/english # Create a file where the InnoDB/XtraDB engine stores it's data loose-innodb_data_file_path = ibdata1:1000M loose-innodb_file_per_table # This is the prefix name to be used for all log, error and replication files log-basename=mysqld # Enable logging by default to help find problems general-log log-slow-queries
