Strange database connection problem
Posted: Tue Jan 10, 2017 9:47 pm
Hi all, I used to use MythTV a long time ago, and am now getting back into it again. This time, I'm trying to set up a standard PC only for the backend and a Raspberry Pi to run the frontend. "mythtv" is the name of the backend bound to the IP address 192.168.1.9 running Debian Jessie, "raspberrypi" is the name of the frontend running raspbian and "voyager" is the name of my main computer not involved with mythtv. Both frontend & backend are using precompiled 0.28 binaries downloaded from the official repositories.
I've set up MythTV on "mythtv", and it seems to be working fine:
Running mythfrontend shows the standard setup wizard and I enter the database address which is 192.168.1.9 as shown in the picture below:
This is confirmed in the config.xml file on the frontend:
Connecting to the mysql server works fine:
But when I try to run mythfrontend, it tries to connect to the backend on localhost for some reason, which obviously fails:
I don't understand why the frontend is trying to connect to 127.0.0.1 and not 192.168.1.9 where the backend is located? I've double checked mythtv-setup on the backend and it shows "192.168.1.9" on both fields in the first screen.
Some help would be greatly appreciated!
With kind regards - Eddles
