= Using the RDBMS

Connect to the MySQL/MariaDB shell using the `mysql` command.

For both of them, the command is `mysql`. The syntax an the options are generally the same.

----
$ mysql -u root -p
----

Once gained access to the shell you can get the running version of the software:

----
mysql> SELECT version();
----

You can create a database:

----
mysql> create schema test;
----

Create a user:

----
mysql> GRANT ALL PRIVILEGES ON test.* TO 'my_user'@'localhost' IDENTIFIED BY 'PaSsWoRd';
----

List the available databases:

----
mysql> show schemas;
----

== Files location

For both of them, the main configuration file is `/etc/my.cnf`; eventually the configuration can be splitted in many files inside the include directory `/etc/my.cnf.d`.

Log files can be located in `/var/log/mysql` for MySQL, and `/var/log/mariabd` for MariaDB.

The database disk storage is located in `/var/lib/mysql`.
