Installing MariaDB/MySQL system tables in '/maria_data/' ...
2016-06-17 17:31:21 140423554045920 [Note] ./bin/mysqld (mysqld 10.1.14-MariaDB) starting as process 13621 ...
Installation of system tables failed! Examine the logs in
/maria_data/ for more information.
The problem could be conflicting information in an externalmy.cnf files. You can ignore these by doing:
shell> ./bin/scripts/mysql_install_db --defaults-file=~/.my.cnf
You can also try to start the mysqld daemon with:
shell> ./bin/mysqld --skip-grant --general-log &
and use the command line tool ./bin/mysql
to connect to the mysql database and look at the grant tables:
shell> ./bin/mysql -u root mysql
mysql> show tables;
Try 'mysqld --help' if you have problems with paths. Using
--general-log gives you a log in /maria_data/ that may be helpful.

OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:
'./bin/mysqladmin' -u root password 'new-password'
'./bin/mysqladmin' -u root -h localhost.localdomain password 'new-password'
Alternatively you can run:
'./bin/mysql_secure_installation'
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.
You can start the MariaDB daemon with:
cd '.' ; ./bin/mysqld_safe --datadir='/maria_data/'
You can test the MariaDB daemon with mysql-test-run.pl
cd './mysql-test' ; perl mysql-test-run.pl
