編排服務 — 安裝和配置：

控制節點操作：

先決條件：

1、按步驟操作。

# mysql -u root -p***
> CREATE DATABASE heat;
> GRANT ALL PRIVILEGES ON heat.* TO ‘heat‘@‘localhost‘ IDENTIFIED BY ‘HEAT_DBPASS‘;
> GRANT ALL PRIVILEGES ON heat.* TO ‘heat‘@‘%‘ IDENTIFIED BY ‘HEAT_DBPASS‘;
> exit();
# . admin-openrc
# openstack user create --domain default --password-prompt heat
# openstack role add --project service --user heat admin
# openstack service create --name heat --description "Orchestration" orchestration
# openstack service create --name heat-cfn --description "Orchestration"  cloudformation
# openstack endpoint create --region RegionOne orchestration public http://controller:8004/v1/%\(tenant_id\)s
# openstack endpoint create --region RegionOne orchestration internal http://controller:8004/v1/%\(tenant_id\)s
# openstack endpoint create --region RegionOne orchestration admin http://controller:8004/v1/%\(tenant_id\)s
# openstack endpoint create --region RegionOne cloudformation public http://controller:8000/v1
# openstack endpoint create --region RegionOne cloudformation internal http://controller:8000/v1
# openstack endpoint create --region RegionOne cloudformation admin http://controller:8000/v1
# openstack domain create --description "Stack projects and users" heat
# openstack user create --domain heat --password-prompt heat_domain_admin
# openstack role add --domain heat --user-domain heat --user heat_domain_admin admin
# openstack role create heat_stack_owner
# openstack role add --project demo --user demo heat_stack_owner
# openstack role create heat_stack_user

安裝並配置組件：

1、安裝包。

# yum install -y openstack-heat-api openstack-heat-api-cfn openstack-heat-engine

2、編輯 /etc/heat/heat.conf 文件。

[database]
connection = mysql+pymysql://heat:HEAT_DBPASS@controller/heat

[DEFAULT]
rpc_backend = rabbit
heat_metadata_server_url = http://controller:8000
heat_waitcondition_server_url = http://
 
controller:8000/v1/waitcondition
stack_domain_admin = heat_domain_admin
stack_domain_admin_password = HEAT_DOMAIN_PASS
stack_user_domain_name = heat

[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS

[keystone_authtoken]
auth_uri = http://controller:5000
 

auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = heat
password = HEAT_PASS

[trustee]
auth_plugin = password
auth_url = http://controller:35357
username = heat
password = HEAT_PASS
user_domain_name = default

[clients_keystone]
auth_uri = http://controller:35357

[ec2authtoken]
auth_uri = http://controller:5000/v2.0

3、同步Orchestration數據庫並驗證。

# su -s /bin/sh -c "heat-manage db_sync" heat
# mysql -uheat -pHEAT_DBPASS -hcontroller -t heat -e "show tables"

4、啟動 Orchestration 服務並設置為隨系統啟動。

# systemctl enable openstack-heat-api openstack-heat-api-cfn openstack-heat-engine
# systemctl start  openstack-heat-api openstack-heat-api-cfn openstack-heat-engine

編排服務 — 驗證操作：

控制節點操作：

1、如下操作。

# . admin-openrc
# openstack orchestration service list
