Find the route across the machine, but no response

[badounan]

I have two physical machines. IP addresses are 192.168.0.10 and 192.168.0.11 respectively.

Start consul sever and fabio on 192.168.10.

Start the consul client and http server on 192.168.0.11. The json registered to consul's service is as follows:
{"service": {"id": "sampleservice","name":"sampleservice","tags": ["urlprefix-/foo"],"address": "192.168.0.11","port": 8088,"checks": [{"deregisterCriticalServiceAfter": "5m","http": "http://192.168.0.11:8088/foo","interval": "10s"}]}}

Http service is running normally in consul.

But visit http://192.168.0.10:9999/foo, has been no response, there is no log output.

Are both checks in consul green? Is the consul cluster healthy?

Can you provide curl -i localhost:8500/v1/health/service/sampleservice?pretty ?

As a side note: use a unique id value for your service, e.g. <name>-<addr>-<port> Otherwise, this won't work with multiple instances.

I only started the http service on 192.168.0.11.There is only one instance of the service.

If I put fabio, consul and http services are deployed on a machine. no problem.

[badounan]

If the address is wrong, the output "No route for ...", which is very correct.

But when i visit a normal address:http://192.168.0.10:9999/foo, without any response, has been waiting.there is no log output.

[magiconair]

what does curl -i http://192.168.0.11:8080/foo return?

[badounan]

yes, when curl -i http://192.168.0.11:8080/foo,the return is normal

[badounan]

but when curl -i http://192.168.0.10:9999/foo，noo response, no output, has been waiting for the state

[magiconair]

Can you provide curl -i localhost:8500/v1/health/service/sampleservice?pretty?

My suspicion is that your consul servers aren't talking to each other. That fabio is talking to consul on 192.168.0.10 and your service is registered on 192.168.0.11.

How did you configure the consul cluster? Can you provide the full and exact commands you ran?

Can you also provide the fabio log? When it starts up it should have a log line like this:

route add sampleservice /foo http://192.168.0.11:8088/

Can you provide the output of curl -i http://192.168.0.10/v1/health/service/sampleservice?pretty.

consul agent -server -bootstrap-expect 2 -data-dir /data/test -node n1 -bind=192.168.0.10 -ui-dir ./consul_ui -dc=dc1

consul agent -server -bootstrap-expect 2 -data-dir /data/test -node n1 -bind=192.168.0.11 -dc=dc1

Then on 192.168.0.10,enter: "consul join 192.168.0.11"
Automatic election leader.

Yes, Fabio have a log:

route add sampleservice /foo http://192.168.0.11:8088/

[magiconair]

ok, then fabio has found the service and added a route. Therefore, the consul setup is correct. Can provide the full command and output of these commands assuming fabio listens on port 9999:

curl -i http://192.168.0.10:9999/foo 
curl -i http://192.168.0.11:8088/foo

[magiconair]

Also, are you sure you've registered the second node with node name n1? The health check says n2. I suggest copying the commands you typed from the terminal or the shell history.

[magiconair]

Sorry, grasping at straws here. I'm sure this is something trivial but I don't see it. If this wouldn't work nothing would work. So bear with me.

Hello!
I use Nancy as the http server. When I curl -i http://192.168.0.10:9999/foo, close the http server, fabio have the following error:

http:proxy error:read tcp 192.168.0.10:60188->192.168.0.11:8088: wsarecv:An existing connection was forcibly closed by the remote host.
