MariaDB is replacing MySQL in Fedora - Tiny Tiny RSS

MariaDB will be replacing MySQL as the default beginning with Fedora 19.  Fedora 19 is scheduled to be released in July, 2013. 

If you are running Tiny Tiny RSS and wish to convert now, I would suggest the following sequence:

As root:
systemctl stop ttrss-update.service
systemctl stop httpd.service
systemctl stop searchd.service
systemctl stop mysqld.service

>>>> Follow these instructions...

>>>> Then issue the upgrade command to clean things up for mariadb:
systemctl start mysqld.service
mysql_upgrade -u root -p
>>> Enter your mysql root password to continue

>>>> When finished restart the mysqld.service
systemctl restart mysqld.service

>>>> Now bring the rest of it back up
systemctl start seachd.service
systemctl start httpd.service
systemctl start ttrss-update.service

You're done.
