Need help deploying Master Server

Since the main Unity master server appears to be crumpling under the load of all the great new games coming out, it looks like deploying my own master server is my only option to keep my multiplayer game functioning.

I have a vps running Ubuntu, but am not too familiar administrating Linux systems from the command line.

After SSHing into my vps, downloading the latest master server source, uncompressing it into /usr/bin/unity_master_server, and running make, I got what looks to me like a big mess
http://tinypaste.com/35862

I would really appreciate it if someone could post step by step instructions for deploying a master server.

(And once it is compiled, how do I start and configure it, and is there anything else I need to do to make sure it always restarts when my server does?)

Thanks!

You're missing curses.h, which probably means you need to download the development tools for your linux install. I ran into the same problem on CentOS, I think I was missing automake, GCC and a few other bits.

You need to build both the connection tester and master server.
When you start the connection tester it will attempt to connect to the master server, so better to start it second.
The IP address is hardcoded in the Connection tester, so you'll need to modify the source code. Below is another version of ConnTester.cpp which defaults to 127.0.0.1, but you can specify your own IP and port options;

Code (csharp):

1. ConnTester %ConnTesterPort% %FacilitatorIP% %FacilitatorPort%

Thanks!

After installing ncurses, the master server compiled perfectly and appears to be working.
I wasn't expecting it to be that easy

Hmm...

Adding the line:

/usr/bin/unity_master_server/masterserver

to my rc.local file seemed to work, but a couple hours later all my sites started randomly dropping offline... I finally traced the problem to the fact that my DNS server wasn't running

If I run the /usr/bin/unity_master_server/masterserver line from a terminal window after my server has started everything works great, but if I put it in the rc.local file it seems to prevent my DNS server from starting. Is this because the Unity master server doesn't return control to the rc.local script after it has started? I examined the source code of the master server, but don't see any parameter that would cause it to act like a normal "start" script that doesn't sieze control of the shell.

What should I put in my rc.local file to start the master server automatically?
