install keystone components

[root@yjwang0-stack-01 ~]# yum -y install openstack-keystone httpd mod_wsgi

Edit keystone config

[root@yjwang0-stack-01 ~]# grep -Ev '^#|^$' /etc/keystone/keystone.conf 
...
[database]
connection = mysql+pymysql://keystone:testtest@controller/keystone
...
[token]
provider = fernet
...

Populate the Identity service database:

[root@yjwang0-stack-01 ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone

Initialize Fernet key repositories:

[root@yjwang0-stack-01 ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
[root@yjwang0-stack-01 ~]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

Bootstrap the Identity service:

keystone-manage bootstrap --bootstrap-password testtest \
  --bootstrap-admin-url http://controller:5000/v3/ \
  --bootstrap-internal-url http://controller:5000/v3/ \
  --bootstrap-public-url http://controller:5000/v3/ \
  --bootstrap-region-id RegionOne

[root@yjwang0-stack-01 ~]# grep -i 'servername' /etc/httpd/conf/httpd.conf

# ServerName gives the name and port that the server uses to identify itself.
ServerName controller

Create symbolic links

[root@yjwang0-stack-01 ~]# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
