Nova-compute not showing on nova service-list(controller)

Hi,

Im not seeing the nova-compute service running for host compute on the controller side.

The service nova-compute is running on compute node but nova-compute log shows:

Error oslo.messaging._drivers.impl_rabbit [-] AMQP server on controller:5672 is unreachable: socket closed. Trying again in 30 seconds.

ntp is installed on both hosts but I did have a problem before when configuring. Running ntpq -c peers shows:

remote *LOCAL(0) refid .LOCL. st 5 t 1 when 28 poll 64 reach 377 deay 0.000 offset 0.000 jitter 0.000.

Any ideas?

Could you paste nova.conf file of compute node. Where did you installed rabbitmq server. Whether rabbitmq server is running ? Add your rabbitmq server ip address, username and password in nova.conf file on compute node

Hello the log file usually is locaten in /var/log/nova/nova-compute.log (The location is on the conf file.)

Hi Oscar,

By seeing the log you pasted here, it seems like nova conductor is not running.

once check the status of nova-conductor like

 service nova-conductor  status

if the status of nova-conductor is down, restart the nova-conductor service like

 service nova-conductor restart

so once again restart the services like mysql,rabbitmq-server and all nova services. if there is any another issue let me know.

Thanks, I already restarted averything and checked the conf file. It clearly has to do with rabbitmq but no idea of what. How can I check if the port is allowed to connect through firewall. I ran: telnet controller 5672 on the compute node and it connected but then "Connection closed by foreign host

the mapping between hosts name and ip addresses may be went wrong in the etc/hosts. once again check the rabbitmq-server credentials in nova.conf like

  vi  /etc/nova/nova.conf

could you please display the compute log files once again?

Hi, It is not.

It was solved apparently it had to do with the rabbit password for guest.

credentials seem to be fine..and controller is in /etc/hosts.

@oscar I have the same problem. In my environment i have already 3 compute nodes that communicates without error with conductor but a new one compute service start to talk successfully but after some changes stopped. my guess is something wrong with package versions happen (python-oslo.*)
