[Rdo-list] Neutron fails to connect to AMQP Server on Fedora 20 ( at startup) 3

[Boris Derzhavets]

Next  fresh install F20 &  Havana via native repo.

Issue seems to be related to https://bugzilla.redhat.com/show_bug.cgi?id=1051593 

Straight forward `packstack --alinone`  install via native Havana repo with no problems.
Openstack-status is fine immediately after RDO setup
 
Recreating external network, OVS bridge "br-ex"  and p37p1 as OVS port for "br-ex"

Reboot.
Openstack-status reports server errors

1.)
[root at openstack1 neutron(keystone_admin)]# nova  net-list
reports server error

2)
[root at openstack1 neutron(keystone_admin)]# nova  service-list
shows state  down every where

3)
/var/log/neutron/server.log.gz  is attached.

I believe to fix it , but it's just a hack

[boris at openstack1 ~]$ sudo su -

[root at openstack1 ~]# ls -l /etc/neutron/neutron.conf
-rw-r-----. 1 root neutron 14386 Jan 12 16:15 /etc/neutron/neutron.conf

[root at openstack1 ~]# vi /etc/neutron/neutron.conf

Uncommented :

# Paste configuration file
api_paste_config = api-paste.ini

Updated /etc/rc.d/rc.local :-

[root at openstack1 neutron(keystone_admin)]# cat /etc/rc.d/rc.local
#!/bin/sh
losetup -f /var/lib/cinder/cinder-volumes && vgchange -a y cinder-volumes && systemctl restart openstack-cinder-volume.service
ifdown br-ex ;
ifup br-ex ;
service network restart ;
# Three times would be enough in general , but may be less
systemctl restart qpidd.service ;
systemctl restart qpidd.service ;
systemctl restart qpidd.service ;
service openstack-nova-compute restart ;
exit 0

Then in openstack-status report instead of server errors I get :-
