根据openstack官方文档配置

官方文档地址: http://docs.openstack.org/juno/install-guide/install/yum/content/#

0x01.认证服务安装与配置(控制节点)

[root@controller ~]# mysql -uroot -p
MariaDB [(none)]> CREATE DATABASE keystone;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
-> IDENTIFIED BY 'KEYSTONE_DBPASS';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
-> IDENTIFIED BY 'KEYSTONE_DBPASS';

MariaDB [(none)]> flush privileges;

[root@controller ~]# openssl rand -hex 
cdda1486bf623ac74d53
[root@controller ~]# yum install -y openstack-keystone python-keystoneclient
[root@controller ~]# cp -rf /etc/keystone/keystone.conf /etc/keystone/keystone.conf.old

[root@controller ~]# vi /etc/keystone/keystone.conf   #增加一下配置就可以了
[DEFAULT]
admin_token = cdda1486bf623ac74d53
verbose = True

[database]
connection = mysql://keystone:KEYSTONE_DBPASS@controller/keystone

[token]
provider = keystone.token.providers.uuid.Provider
driver = keystone.token.persistence.backends.sql.Token

[revoke]
driver = keystone.contrib.revoke.backends.sql.Revoke

[root@controller ~]# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone
[root@controller ~]# chown -R keystone:keystone /var/log/keystone
[root@controller ~]# chown -R keystone:keystone /etc/keystone/ssl
[root@controller ~]# chmod -R o-rwx /etc/keystone/ssl
[root@controller ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone

[root@controller ~]# systemctl enable openstack-keystone.service
[root@controller ~]# systemctl start openstack-keystone.service

0x02. Create tenants, users, and roles(控制节点)

[root@controller ~]# export OS_SERVICE_TOKEN=cdda1486bf623ac74d53
[root@controller ~]# export OS_SERVICE_ENDPOINT=http://controller:35357/v2.0

2-1. Create an administrative tenant, user, and role for administrative operations in your environment:
　　a. Create the admin tenant:(创建租户admin)

[root@controller ~]# keystone tenant-create --name admin --description "Admin Tenant"
+-------------+----------------------------------+
| Property | Value |
+-------------+----------------------------------+
| description | Admin Tenant |
| enabled | True |
| id | f42937a2fd484d638ce58e67fef59b67 |
| name | admin |
+-------------+----------------------------------+

　　b. Create the admin user:(创建用户admin)

[root@controller ~]# keystone user-create --name admin --pass ADMIN_PASS --email admin@example.com

+----------+----------------------------------+
| Property | Value |
+----------+----------------------------------+
| email | admin@example.com |
| enabled | True |
| id | cc58749f0ecb402d9f627ee72bda5afb |
| name | admin |
| username | admin |
+----------+----------------------------------+

　　c. Create the admin role:(创建角色admin)

[root@controller ~]# keystone role-create --name admin
+----------+----------------------------------+
| Property | Value |
+----------+----------------------------------+
| id | 4fa15a3b9fc6464694696fa75696b191 |
| name | admin |
+----------+----------------------------------+

　　d. Add the admin role to the admin tenant and user:(添加用户到租户以及角色中)

[root@controller ~]# keystone user-role-add --user admin --tenant admin --role admin

2-2. Create a demo tenant and user for typical operations in your environment:
　　a. Create the demo tenant:(创建租户demo)

[root@controller ~]# keystone tenant-create --name demo --description "Demo Tenant"
+-------------+----------------------------------+
| Property | Value |
+-------------+----------------------------------+
| description | Demo Tenant |
| enabled | True |
| id | e15976585a8b45c4984f4ebd9db90b5c |
| name | demo |
+-------------+----------------------------------+

　　b. Create the demo user under the demo tenant:(添加demo用户到租户demo中)

[root@controller ~]# keystone user-create --name demo --tenant demo --pass DEMO_PASS --email demo@example.com
+----------+----------------------------------+
| Property | Value |
+----------+----------------------------------+
| email | demo@example.com |
| enabled | True |
| id | 5c8155359c20422c96e7bcd6aa6388ba |
| name | demo |
| tenantId | e15976585a8b45c4984f4ebd9db90b5c |
| username | demo |
+----------+----------------------------------+

2-3.OpenStack services also require a tenant, user, and role to interact with other services.
Each service typically requires creating one or more unique users with the admin role
under the service tenant

　a. Create the service tenant:(创建租户service)

[root@controller ~]# keystone tenant-create --name service --description "Service Tenant"
+-------------+----------------------------------+
| Property | Value |
+-------------+----------------------------------+
| description | Service Tenant |
| enabled | True |
| id | 6826a4d9fa7f4e438f3c79010ad80dcd |
| name | service |
+-------------+----------------------------------+

0x03. Create the service entity and API endpoint(控制节点)
　　3-1. Create the service entity for the Identity service:

[root@controller ~]# keystone service-create --name keystone --type identity \
--description "OpenStack Identity"
+-------------+----------------------------------+
| Property | Value |
+-------------+----------------------------------+
| description | OpenStack Identity |
| enabled | True |
| id | 5da5b6f72df341a7959ee7b42131c082 |
| name | keystone |
| type | identity |
+-------------+----------------------------------+

　　3-2. Create the Identity service API endpoints:

[root@controller ~]# keystone endpoint-create \
--service-id $(keystone service-list | awk '/ identity / {print $2}') \
--publicurl http://controller:5000/v2.0 \
--internalurl http://controller:5000/v2.0 \
--adminurl http://controller:35357/v2.0 \
--region regionOne
+-------------+----------------------------------+
| Property | Value |
+-------------+----------------------------------+
| adminurl | http://controller:35357/v2.0 |
| id | 90af99e76cc54249b5ac3ec4269b0d99 |
| internalurl | http://controller:5000/v2.0 |
| publicurl | http://controller:5000/v2.0 |
| region | regionOne |
| service_id | 5da5b6f72df341a7959ee7b42131c082 |
+-------------+----------------------------------+
