I'm trying to install and configure OpenStack following the instructions described in "http://docs.openstack.org/liberty/install-guide-rdo/keystone-install.html"

My OS is the minimal centos7. I'm using MariaDB.

In the OpenStack Identity install and configure part, for the below step Populate the Identity service database:

su -s /bin/sh -c "keystone-manage db_sync" keystone

I'm getting following error: No handlers could be found for logger "oslo_config.cfg"

my /etc/keystone/keystone.conf is below: [DEFAULT] admin_token = e7a77325188ac4799eca verbose = True [database] connection = mysql://keystone:Ks12345678@controller/keystone [memcache] servers = localhost:11211 [token] provider = uuid driver = memcache [revoke] driver = sql

Could someone please tell me what's wrong with my setup ?
