Shoutcast Hot Standby Server setup

[thewoose]

Hi,

I have been searching these forums for a long time trying to find out how to do this, but no luck so far.

I have a main SC server located in Denmark, and a "hot standby" server in the US. What I would like to do is have both of them show up in the YP as one server instead of two, and do an automatic failover should the main server become overloaded.

Is this possible to do with completely different machines?

Thanks,
Steve

If you have enough bandwidth, I'd say connect an encoder to both at the same time.
That way if one goes down, the other is still up. If you let listeners connect using a playlist file with both servers, then if one goes down the listeners should automatically "roll over" to the next entry in the playlist.

as long as the servers have been clustered together correctly, then at least with a v1 DNAS it should be sending clients to the 'backup' which the YP provides back to the DNAS.

with the v2 DNAS it's a bit funky with the current public build for doing that but has been resolved in the internal builds.

in either case, as long as the clustering is done correctly, then the YP will put the server with the most free slots first in the list and will change what is provided as time goes on. if someone connects directly then (barring any bugs) should redirect that if the DNAS has a known backup.


the only issue to that is it means both will be used at the same time - it sounds a bit like you only want the main being used unless there is an issue. if that is the case then what i've described probably isn't going to fit your needs and you might then need to do funky stuff like proxy handling to control who gets sent to what DNAS, etc.
