[Software] [OpenStack]Zed - Bullseye - Placement verification error - Unable to establish connection - Errno 111

#1 Post by sevilla.larry »

Summary: Verifying installation of Placement API with OpenStack Zed under Debian 11 Bullseye gives error msg "Unable to establish connection", errno 111.

Details:

I'm new to OpenStack.

I have used these guides:
OpenStack Installation Guide documentation https://docs.openstack.org/install-guide/
Installation — openstack-placement 8.0.0.0rc2.dev2 documentation https://docs.openstack.org/placement/zed/install/

I successfully installed OpenStack Zed with Ubuntu 22.04 LTS Jammy Jellyfish, and tested Dashboard usage. And so far no problem encountered.

Then, I'm trying to install Openstack with Debian 11 Bullseye (since Ubuntu was derived from Debian), but I'm getting errors on the Placement verification.

I followed the same/similar procedures under Ubuntu with Debian installation:
Installed NTP, OpenStack packages, MariaDB SQL, RabbitMQ, memcached, etcd.
Installed Keystone, Glance,
And installed Placement successfully.

with this guide:
https://docs.openstack.org/placement/ze ... erify.html

Code: Select all

placement-status upgrade check
(no problem)

Code: Select all

pip3 install osc-placement

The following 2 lines give ERRORs

Code: Select all

openstack --os-placement-api-version 1.2 resource class list --sort-column name
openstack --os-placement-api-version 1.6 trait list --sort-column name
error msg:
Unable to establish connection to http://controller:8778/resource_classes: HTTPConnectionPool(host='controller', port=8778): Max retries exceeded with url: /resource_classes (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0xHHHH>: Failed to establish a new connection: [Errno 111] Connection refused'))
I also tried to:

Code: Select all

pip3 uninstall osc-placement
apt install osc-placement
(since this was successful with the Ubuntu Zed installation), but got the same errors

checking endpoints with:

Code: Select all

openstack endpoint list
(endpoints are existing for Placement http://controller:8778)

in the /var/log/apache2/error.log, there was an entry:
[date&time] mpm_eventnotice] [pid xxx:tid xxxxx] AH00492: caught SIGWINCH, shutting down gracefully.
