<br>
Getting multi-master to work has only gone so far.<br>
<br>
I can set up a database and have masters talk to it just fine. And the<br>
masters can mostly function correctly. I'm using mostly<br>
master.cfg.sample instead of our own because I want something smaller. I<br>
have 2 masters that are mostly the same except for various names, and<br>
only 1 is running a UI.<br>
<br>
I don't seem to be able to have them talk to crossbar. And there's not<br>
many log messages giving me a clue as to what's going on. I suspect my<br>
crossbar configuration. But the default configuration with a changed<br>
realm and port doesn't seem to work, either.<br>
<br>
My first attempt had this:<br>
c['mq'] = {<br>
'type' : 'wamp',<br>
'router_url': 'ws://ws/buildbot',<br>
'realm': 'buildbot',<br>
'debug' : True,<br>
'debug_websockets' : True,<br>
'debug_lowlevel' : True,<br>
}<br>
<br>
Obviously incorrect, as there's no host:port in there. Using my<br>
handwritten config.json on the crossbar side, here's what happens.<br>
Crossbar starts, and since I'm not putting the log in a file, I can see<br>
it on my terminal, and it looks fine enough. Then I start buildbot, and<br>
the only entries I see that might be relevant are:<br>
2016-09-02 12:34:50-0400 [-] Starting wamp with config: %r {'realm':<br>
'buildbot', 'debug_lowlevel': True, 'router_url': 'ws://ws/buildbot',<br>

<br>
and that's it. OK, so I put in the host:port into master.cfg:<br>
c['mq'] = {<br>
'type' : 'wamp',<br>
'router_url': 'ws://<a href="http://127.0.0.1:8020/ws/buildbot" rel="noreferrer" target="_blank">127.0.0.1:8020/ws/buildbot</a>',<br>
'realm': 'buildbot',<br>
'debug' : True,<br>
'debug_websockets' : True,<br>
'debug_lowlevel' : True,<br>
}<br>
<br>
and my config.json looks like the one in the crossbar defaults, except<br>
for the transport, which looks like this:<br>
"transports": [<br>
{<br>
"type": "websocket",<br>
"endpoint": {<br>
"type": "tcp",<br>
"port": 8020<br>
},<br>
"url": "ws://ws/buildbot",<br>
"auth": {<br>
"anonymous": {<br>
"type": "static",<br>
"role": "public"<br>
}<br>
}<br>
}<br>
]<br>
<br>
and try again. This time, I get a crossbar log entry:<br>

handshake ('port 8020 in HTTP Host header '<a href="http://127.0.0.1:8020" rel="noreferrer" target="_blank">127.0.0.1:8020</a>' does not<br>

and on buildbot:<br>

<br>
Betterm I think. At least I get an error, and both sides agree. But why<br>
is my crossbar listening on 80 when I told it 8020? OK, we'll try port<br>
80 then...<br>
<br>
(same mq, just change the port)<br>
<br>
No messages from crossbar. From buildbot:<br>

<br>
So no connection there, either.<br>
<br>
OK, we'll try the default config.json, and only change the port. It's<br>
transports look like this:<br>
"transports": [<br>
{<br>
"type": "universal",<br>
"endpoint": {<br>
"type": "tcp",<br>
"port": 8020<br>
},<br>
"websocket": {<br>
"ws": {<br>
"type": "websocket"<br>
}<br>
}<br>
}<br>
]<br>
<br>
We'll also have to change master.cfg to match urls:<br>
c['mq'] = {<br>
'type' : 'wamp',<br>
'router_url': 'ws://<a href="http://127.0.0.1:8020/ws" rel="noreferrer" target="_blank">127.0.0.1:8020/ws</a>',<br>
'realm': 'buildbot',<br>
'debug' : True,<br>
'debug_websockets' : True,<br>
'debug_lowlevel' : True,<br>
}<br>
<br>
Crossbar starts fine. Buildbot excepts:<br>
