8 enable_keystone: "yes"

region two：（region_one_vip：regionOne的keystone IP）

 1 cat /etc/kolla/globals.yml
 2 
 3 openstack_region_name: "RegionTwo"
 4 
 5 kolla_internal_fqdn_r1: region_one_vip
 6 keystone_admin_url: "{{ admin_protocol }}://{{ kolla_internal_fqdn_r1 }}:{{ keystone_admin_port }}"
 7 keystone_internal_url: "{{ internal_protocol }}://{{ kolla_internal_fqdn_r1 }}:{{ keystone_public_port }}"
 8 
 9 openstack_auth:
10     auth_url: "{{ admin_protocol }}://{{ kolla_internal_fqdn_r1 }}:{{ keystone_admin_port }}"
11     username: "admin"
12     password: "{{ keystone_admin_password }}"
13     project_name: "admin"
14     domain_name: "default"
15 
16 enable_keystone: "no"

region two：

1 [root@controller ~]# cat /etc/kolla/config/global.conf 
2 [keystone_authtoken]
3 auth_uri = {{ keystone_internal_url }}
4 auth_url = {{ keystone_admin_url }}

1 [root@controller ~]# cat /etc/kolla/config/mistral.conf 
2 [keystone_authtoken]
3 auth_uri = {{ keystone_internal_url }}/v3
4 auth_url = {{ keystone_admin_url }}/v3
5 [openstack_actions]
6 default_region = RegionTwo

 1 [root@controller ~]# cat /etc/kolla/config/heat.conf 
 2 [DEFAULT]
 3 region_name_for_services = RegionTwo  
 4 [trustee]
 5 auth_uri = {{ keystone_internal_url }}
 6 auth_url = {{ keystone_internal_url }}
 7 [ec2authtoken]
 8 auth_uri = {{ keystone_internal_url }}
 9 [clients_keystone]
10 auth_uri = {{ keystone_internal_url }}
