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.

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
