Errno 111 Connection refused Error INFO nova wsgi - Stopping WSGI server INFO nova openstack common service - Caught SIGTERM exiting

Question

I got this error when I executed one of the nova command.

[root@gcontroller]# nova net-list
ERROR: [Errno 111] Connection refused

The log files under /var/log/nova revealed the above error.

INFO nova.wsgi [-] Stopping WSGI server.
INFO nova.wsgi [-] WSGI server has stopped.
INFO nova.wsgi [-] WSGI server has stopped.
INFO nova.wsgi [-] WSGI server has stopped.
INFO nova.openstack.common.service [-] Caught SIGTERM, exiting

How can I solve this error?

Thank You

Hi@akhtar,

Whenever you see “Connection refused” error, it’s clear that one of the necessary service is not running properly.

To fix the issue,

1. $ vi /etc/nova/nova.conf

2. Lookout for ‘enabled_apis‘ and its value ‘ec2,osapi_compute,metadata‘

3. Remove ‘metadata’ from ‘enabled_apis’

4. Now, you are good to start both ‘openstack-nova-api‘ and ‘openstack-nova-metadata-api‘. Both the service will run individually.

In case, if you wish to start ‘metadata-api’ along with ‘openstack-nova-api’ then leave ‘enabled_apis’ with values as ‘ec2,osapi_compute,metadata’ and stop ‘openstack-nova-metadata-api‘ from starting during the system boot. To do that, you can just run the below commands.

$ chkconfig openstack-nova-metadata-api off
$ chkconfig openstack-nova-api on

Hope this will work.

Thank You
