glance-api cannot start - CentOS

[Boon Lee]

Hi there,

I was following the instructions to install openstack (icehouse) on centos and encountered issue with glance-api not able to start. I am following the installation sequence of the document - keystone installed & verified seems ok. Then I installed image service openstack-glance but glance-api won't start (glance-registry starts ok)

[root@controller glance]# service openstack-glance-api status
openstack-glance-api dead but pid file exists

Looking at api.log, I can see these error logs:

One quick comment: It looks like your install is trying to look for rabbitMQ as a queueing service, whereas Centos should use QPID.

This could be a problem with the guide. Standby.

[Tom Fifield (fifieldt)]

Try running these commands and restarting the services:

# openstack-config --set /etc/glance/glance-api.conf \
  DEFAULT rpc_backend glance.openstack.common.rpc.impl_qpid
# openstack-config --set /etc/glance/glance-api.conf DEFAULT qpid_hostname controller

# openstack-config --set /etc/glance/glance-registry.conf \
  DEFAULT rpc_backend glance.openstack.common.rpc.impl_qpid
# openstack-config --set /etc/glance/glance-registry.conf DEFAULT qpid_hostname controller

Hi Tom,

glance-api runs now!

[root@controller ~]# service openstack-glance-api status

Many Thks!

    Add explicit msg q conf instructions to glance

    As reported by user Boon Lee, the glance install instructions
    for Icehouse under Centos were failing because the message
    queue was not being configured.

    This patch includes explicit message queue configuration, such as
    in compute and networking.
