-failed to initialize the data file of the MySQL database

[root@localhost maria] # / scripts/mysql_install_db-- user=mysql-- datadir=/maria_data/

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 external

My.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
