Rabbitmq Server won't listen to 5672 in ipv4 after reboot

[Darren Wang]

Hi every one,

I encountered this problem when I was deploying OpenStack. Some of the services just can't get connected to rabbitmq-server.

I'm sure that rabbitmq-server is running and the userid/password in openstack config files are correct. I checked the status of port 5672 but to found that rabbitmq-server is not listening to port 5672 in IPV4, so how coud I solve this problem ?

# root@ISeR-Server1:~# netstat -ntlp | grep 5672

tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      7230/beam.smp

tcp6       0      0 :::5672                 :::*                    LISTEN      7230/beam.smp

What is in RabbitMQ log files?

Does the process have any file descriptors left for it to use? (rabbitmqctl status may be the easiest way to check this)

I misunderstood the issue. RabbitMQ listens on all interfaces unless configured otherwise.

You can manually specify interfaces, see http://www.rabbitmq.com/configure.html:

 * RABBITMQ_NODE_IP_ADDRESS
 * tcp_listeners [1]

There could also be OS level changes that prevent RabbitMQ from binding to a socket. The most common
one is mentioned in Security and Ports on [2]
