WARNING: The host 'zarniwoop.home.hewus.com' could not be looked up with /usr/local/bin/resolveip.

This probably means that your libc libraries are not 100 % compatible

with this binary MariaDB version. The MariaDB daemon, mariadbd, should work

normally with the exception that host name resolving will not work.

This means that you should use IP addresses instead of hostnames

when specifying MariaDB privileges !

Installing MariaDB/MySQL system tables in '/usr/ports/pobj/p5-DBIx-Class-Schema-Loader-0.07053/testdb-mariadb' ...

OK

Two all-privilege accounts were created.

One is root@localhost, it has no password, but you need to

be system 'root' user to connect. Use, for example, sudo mariadb

The second is _mysql@localhost, it has no password either, but

you need to be the system '_mysql' user to connect.

After connecting you can set the password, if you would need to be

able to connect as any of these users with a password and without sudo

See the MariaDB Documentation at https://mariadb.com/docs

You can start the MariaDB daemon with:

/etc/rc.d/mysqld start
