Public bug reported:

Enviroment
OS: CentOS7.2

I deployed the devstack environment successfully in CentOS system. After
rebooting the CentOS system， the keystone service could not be started.
The uwsgi raised exception as follows.

Apr 23 22:38:53 devstack.localdomain systemd[1]: devstack@keystone.service failed.
Apr 23 22:42:46 devstack.localdomain systemd[1]: Starting Devstack devstack@keystone.service...

Apr 23 22:42:46 devstack.localdomain systemd[1]: devstack@keystone.service failed.

So i think this is a bug. I tried to create the /var/run/uwsgi directory and chown it stack user. Then it works.
sudo mkdir -p /var/run/uwsgi
sudo chown stack:stack uwsgi

So what do you think that?
