2.4 Check /var/log/nova/nova-placement-api.log , no this log

RESOLUTION:

1. Start nova-placement-api service :
/usr/bin/nova-placement-api

Check nova-placement-api port , default value is 8000.but it is 8778 in OpenStack guide.

2. Change /usr/bin/nova-placement-api file, from 8000 to 8778

3. Check port whether it is listening:
netstat –an|grep 8778

If you have a troubleshooting or support issue, use the following resources:

 - Ask OpenStack: http://ask.openstack.org
 - The mailing list: http://lists.openstack.org
 - IRC: 'openstack' channel on Freenode

Nicolas/Matt - are you able to take a look at this one?

Thanks.

[Chris Dent (cdent)]

wiston, while your solution may be working for you, it has some issues:

* running /usr/bin/nova-placement-api directory is for testing purposes only, the placement API expects to be run under apache, using mod-wsgi, otherwise performance may be limited

* the reason things aren't working for you is that the apache configuration for the placement service has some issues in the respective packages that install it, resulting in a deployment that cannot work without some tweaks to the apache configuration

What those tweaks are depends on whether you are using Ubuntu or RDO packages and what is currently in your apache configuration.

[wiston (349317925-k)]

about performance limitation of starting placement-api raised by me,I am not sure.
About apache configuration have some error as you said,could you give me some ideas?thanks very much!
