Im fairly new to ubuntu and I currently need some help understanding this error.

As of now, Im working on a server with which to host a WordPress sites using this tutorial: https://deliciousbrains.com/hosting-wordpress-yourself-nginx-php-mysql/ I am currently stuck at trying to setup the default system tables for MariaDB/Mysql(?) (i would also greatly appreciate if someone could help shed some light on what Im actually trying to achieve here, Im trying my hardest to follow it all but I still find it to be quite confusing).

After I installed MariaDB using the instruction from their website: https://downloads.mariadb.org/mariadb/repositories/#distro=Ubuntu&distro_release=xenial--ubuntu_xenial&version=10.1&mirror=supportex and created a root password(for mariadb, not the actual server), whenever i try to run: sudo mysql_install_db i get this error message:

Installing MariaDB/MySQL system tables in '/var/lib/mysql' ...
2017-08-30 11:37:39 140643689761024 [Note] /usr/sbin/mysqld (mysqld 10.1.26-MariaDB-1~xenial) starting as process 2161 ...

Installation of system tables failed!  Examine the logs in
/var/lib/mysql for more information.

The problem could be conflicting information in an external
my.cnf files. You can ignore these by doing:

    shell> /usr/scripts/scripts/mysql_install_db --defaults-file=~/.my.cnf

You can also try to start the mysqld daemon with:

    shell> /usr/sbin/mysqld --skip-grant --general-log &

and use the command line tool /usr/bin/mysql
to connect to the mysql database and look at the grant tables:

    shell> /usr/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 /var/lib/mysql that may be helpful.

The latest information about mysql_install_db is available at
MariaDB is hosted on launchpad; You can find the latest source and
email lists at http://launchpad.net/maria

Please check all of the above before submitting a bug report
at http://mariadb.org/jira

I do not know what's causing this to happen, I already tried reinstalling MariaDB several times to no availl, and it also appears that the file .my.cnf appears to be missing.

If someone could help me solving this problem i would be very grateful!

  • Did you have a look at the log in /var/lib/mysql as suggested? Did you also try the various proposals contained in the error message? You would be one step further. – Marc Vanhoomissen Aug 31 '17 at 13:50
  • I did, however most the log didn't really contain any usefull information and the other 2 options didn't seem to work either. but it not necesary anymore because apparently MariaDB did install aparently, and its working fine. So I dont know what the error was about or wether it has any severe effects on the database storing – Emiel van den Brink Sep 1 '17 at 13:56
