官网文档：OpenStack Docs: Install and configure for Red Hat Enterprise Linux and CentOS

https://docs.openstack.org/heat/train/install/install-rdo.html

---

一、创建heat相关数据库、服务凭证和API端点 1、创建数据库

mysql -p123

MariaDB [(none)]> CREATE DATABASE heat;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON heat.* TO 'heat'@'%' IDENTIFIED BY 'heat123';

我这里设置密码为heat123

MariaDB [(none)]> exit

 

2、获取凭据以获取对仅限管理员的 CLI 命令的访问权限： admin

 . admin-openrc

 

3、创建服务凭据

创建heat 用户：

openstack user create --domain default --password=heat123 heat

添加 admin 角色到 heat 用户上

openstack role add --project service --user heat admin

这个命令执行后没有输出。

创建heat和 heat-cfn 服务实体：

openstack service create --name heat  --description "Orchestration" orchestration

openstack service create --name heat-cfn  --description "Orchestration"  cloudformation

 

4、创建 Orchestration 服务的 API 端点

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

 

5、业务流程需要标识服务中的其他信息来管理堆栈。

1.为栈创建 heat 包含项目和用户的域：

openstack domain create --description "Stack projects and users" heat

2.在 heat 域中创建管理项目和用户的heat_domain_admin用户：

openstack user create --domain heat --password=heat123 heat_domain_admin

我这里设置密码为heat123

3.添加admin角色到 heat 域 中的heat_domain_admin用户，启用heat_domain_admin用户管理栈的管理权限

openstack role add --domain heat --user-domain heat --user heat_domain_admin admin

这个命令执行后没有输出。

4.创建 heat_stack_owner 角色：

openstack role add --project demo --user demo heat_stack_owner

5.添加heat_stack_owner 角色到demo 项目和用户，启用demo 用户管理栈。

openstack role add --project demo --user demo heat_stack_owner


这个命令执行后没有输出。 必须添加 heat_stack_owner 角色到每个管理栈的用户。

注意: 在部署keystone时有会有两个管理用户，一个是admin,一个是demo，这时你报错显示没有demo用，说明当时部署时没有创建demo，这里将demo换成admin已有的用户即可

6.创建 heat_stack_user 角色

openstack role create heat_stack_user

二、安装并配置Heat组件 1、安装软件包

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

 

2.修改heat配置

编辑/etc/heat/heat.conf

[database]
cOnnection= mysql+pymysql://heat:heat123@controller/heat  

#密码以自己的为准


[DEFAULT]
transport_url = rabbit://openstack:openstack@controller


[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = heat
password = heat123

[trustee]
auth_type = password
auth_url = http://controller:5000
username = heat
password = heat123
user_domain_name = default

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


[DEFAULT]
heat_metadata_server_url = http://controller:8000
heat_waitcondition_server_url = http://controller:8000/v1/waitcondition

[DEFAULT]
stack_domain_admin = heat_domain_admin
stack_domain_admin_password = heat123
stack_user_domain_name = heat

3、同步Orchestration数据库

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

三、启动 Orchestration 编排服务heat组件并将其设置为随系统启动

systemctl enable openstack-heat-api.service openstack-heat-api-cfn.service openstack-heat-engine.service

systemctl restart openstack-heat-api.service openstack-heat-api-cfn.service openstack-heat-engine.service
  
systemctl list-unit-files |grep openstack-heat*

四、验证操作 1.获取租户凭据： admin

. admin-openrc

2.列出服务组件以验证每个进程的成功启动和注册

[root@controller ~]# openstack orchestration service list
+------------+-------------+--------------------------------------+------------+--------+----------------------------+--------+
| Hostname   | Binary      | Engine ID                            | Host       | Topic  | Updated At                 | Status |
+------------+-------------+--------------------------------------+------------+--------+----------------------------+--------+

| controller | heat-engine | 7f87f753-d36a-4ffe-ae6f-995b73b0f341 | controller | engine | 2022-06-08T04:18:49.000000 | up     |
+------------+-------------+--------------------------------------+------------+--------+----------------------------+--------+

3.列出服务组件，以验证是否成功启动并注册了每个进程：

[root@controller ~]# openstack service list
+----------------------------------+-----------+----------------+
| ID                               | Name      | Type           |
