MythTV: mythbackend won't start as daemon

wilberfan · 2010-12-21 18:49:11

I just installed the latest MythTV and adding mythbackend to the DAEMONS= to /etc/rc.conf doesn't seem to work. I also tried adding HOME="/root" to rc.conf as suggested in the Wiki.

I can start mythbackend from a command line after logging in...

Any suggestions would be appreciated!

What have you got in /etc/rc.d? and in daemons [rc.conf]

Post the output of

$ mythbackend

I'm thinking something isn't setup properly and that your backend starts, but dies. If you run it manually as I show above, it should stay running indefinitely. If however it stops and you're back at the shell prompt, you haven't setup something properly. Also, I trust that you haven't run any of the myth scripts as root, right?

Dude, I'm new at this! Running mythscripts as root is ENTIRELY possible... [embarassed]

Running $ mythbackend from a terminal window will run indefinitely, yes... Here is some output:

From the output, looks like there are no problems.... does the mythbackend stay running or does it quit after say 30 seconds? If it doesn't quit (stays running), do this (as root)

# /etc/rc.d/mythbackend stop
# /etc/rc.d/mythbackend start

Now wait 30 sec, then post the /var/log/mythbackend.log

It looks like it quits right away (unless run from a command-line):

The difference is that when you start it as a daemon, the root user is owning it.

"Using configuration directory = /root/.mythtv"

Do this as root:

# rm -rf /root/.mythtv
# cp -a /home/wilberfan/.mythtv /root
# chown root:root -R /root/.mythtv

Yeah sorry, typeo - I just edited my post

You're just copying your .mythtv to the root user.

I wondered about the correctness of the original post!

The good news is -- IT WORKS NOW!

Thanks so much for your help...

"No setting found for this machine's BackendServerIP.

You just needed to run mythtv-setup and set the local IP. (mythtv-setup is a GUI and wants mythbackend stopped before it will run.)
