Can't connect to rabbit node?

[ask]

Running ./start.sh I get the following:

=PROGRESS REPORT==== 19-Nov-2009::11:11:41 ===
    application: alice
    started_at: 'alice@h8.opera.com'

Any idea what this could be? rabbit@h8 is definitely running, alive and well.

Using RabbitMQ 1.7.0

[dieu]

change ./start.sh : -name alice -> -sname alice@h8

and well be the same cookie Erlang

[ask]

@dieu that doesn't help either:

./start.sh -alice rabbithost "rabbit@h8" -setcookie $(cat ~/.erlang.cookie) -sname alice@h8

[ericbeland]

I'm seeing the same thing. I'm on OS X. My buddy, who is using Ubuntu has the same problem. I've yet to see Alice working properly. I'm surprised I don't see more complaints.

Lost connection with rabbitmq_server. Trying to regain connection to rabbit@mabel

I have mabel pointed to 127.0.0.1 in my hosts file, and I have been trying various sname suggestions I've seen in the Git issues. Help.

[dieu]

@ask and what is your OS?

I helped to Debian, only I set a cookie through a file ~ /. erlang.cookie

[ask]

@dieu: Debian Lenny, RabbitMQ 1.7.0

[amishyn]

I configure which host should alice use and got next
=ERROR REPORT==== 17-Dec-2009::20:20:10 ===

[dieu]

@amishyn please

erl

net_adm:localhost().

net_adm:names().

node().

nodes().

But in general need to change the host name, it certainly not used validated characters.

[dieu]

@ask

try to link the two erlang node in the cluster, through net_adm:ping(), what a net_adm:names() shows a remote node, nothing says they can still not contacted for some other errors.

I've been having this problem on a RedHat box, and I just got it solved. This was probably due to my overwhelming ignorance of Erlang than anything else, but here is what I did.

1. Find what user the RabbitMQ server is running under. In my case, this is "rabbitmq"
2. Find the erlang cookie for that user. This should be in the home directory for that user. In my case this is in /var/lib/rabbitmq/.erlang.cookie
3. Start alice like this:
   ./start.sh -setcookie "secret-cookie" -name rabbitmq@hostname

This worked for me.

[jakedouglas]

Running on Snow Leopard...had to change rabbitmq-server to use -name instead of -sname and then make sure to use ./startup.sh -setcookie to the same cookie as rabbitmq.

[whbath]

I've now been trying for about a week to get this to work =(.
Regarding tips for using the suggested above; You need to remove the -name arg in the start.sh if you are going to pass it in on the console, otherwise it will try and run it at @nohost due to the confusion of having it both in the script and on the command line.

Regarding my current problem:
I'm running on Ubuntu 9.1, used the debian packages to install rabbitmq and erlang. The rabbitmq server is running at startup at:
[{rabbit@ubuntu,1419}]
It installed itself under the "rabbitmq" user and under my home dir there is a .erlang.cookie that seems to be the one getting the rabbitmq cookie.

If I just use:
./start.sh -setcookie SDWRXMVHVSGVMPRLKZXJ -name "alice@ubuntu.ubuntu-domain"

I get a bunch of loading info which ends in:
=ERROR REPORT==== 6-Feb-2010::17:54:11 ===
Error in process <0.78.0> on node 'alice@ubuntu.ubuntu-domain' with exit value: {badarg,[{erlang,list_to_existing_atom,["rabbit@ubuntu"]},{dist_util,recv_challenge,1},{dist_util,handshake_we_started,1}]}

I'm guessing the issue is the cookie, but that is the one in my "~/.erlang.cookie" which is marked as touched today, I've looked in the "/var/lib/rabbitmq/.erlang.cookie" and that file is stale. Regardless of what I do I just can't seem to make it connect? I've well and truly had several good cracks at this and am not getting anywhere; any help anyone?

[whbath]

It is also worth noting I'm not a Linux or Erlang expert, so my problem is probably quite a simple/stupid one. Is there anyway to figure out what the cookie is for the running rabbitmq server (other than the file) or a better way to set it?

[jasonjackson]

I have the exact same problem, and log output as whbath. I have been working on this for a few days and haven't managed to get anywhere either. Is there anyone out there who has had any success with this? Talking to quite a few folks on IRC, I have yet to meet one that has successfully got this thing to start.

Anyone have any school to lend?

Thanks,

[ask]

I did make it start at some point, but that was before, with other erlang/rabbitmq versions, so I guess it's some issue introduced with the new versions.

[bcotton]

on centos, with rabbitmq 1.7.0 installed from rpm, I got it working by changing start.sh
from
erl -pa $PWD/ebin -pa $PWD/deps//ebin -name alice -s reloader -boot alice $
to
erl -pa $PWD/ebin -pa $PWD/deps//ebin -sname alice -s reloader -boot alice $

basically "-name" to "-sname"

and it worked for me.
