Yes the backend needs to run mythtv-setup.

Test mysql from the command line using the credentials that you're
trying in mythtv-setup. Confirm that mysql is NOT listening on
127.0.0.1 and is instead listening on either all interfaces (0.0.0.0)
or the LAN ip address for that machine. I had a race condition that I
chose to solve by binding to 0.0.0.0 in the /etc/mysql/my.cnf - that
looks like this:

bind-address            = 0.0.0.0

Even with the IP binding correctly you may need to explicitly 'grant
all on mythconverg.* to 'mythtv'@{IP_ADDRESS} identified by
'{PASSWORD}' before it lets each machine connect to the mysql
database. I have not had good luck with 'mythtv'@'%' style grant
statements lately. YMMV.

I'm no mythtv-setup and database expert, but if this were me, I'd be
sure to drop the mythconverg database and re-run the mythtv-setup from
the master-backend only so you don't have a corrupted partial setup
from running mythtv-setup previously.

You could start here - http://www.mythtv.org/wiki/Silicondust_HDHomeRun
