11 安装和配置Heat服务（Orchestration service）

Heat服务（Orchestration service）通过运行OpenStack API调用以生成正在运行的云应用程序，为描述云应用程序提供基于模板的编排。该软件将OpenStack的其他核心组件集成到一个文件模板系统中。这些模板允许您创建大多数OpenStack资源类型，例如实例、浮动IP、卷、安全组和用户。它还提供高级功能，例如实例高可用性、实例自动缩放和嵌套堆栈。这使得OpenStack核心项目能够获得更大的用户群。

该服务允许部署人员直接或通过自定义插件与Orchestration服务集成。

11.1 先决条件

在安装和配置Orchestration之前，必须创建数据库、服务凭据和API端点。业务流程还需要标识服务中的其他信息。

11.1.1 创建数据库并授予权限

[root@xgk-ctl ~]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 4255
Server version: 10.5.16-MariaDB MariaDB ServerCopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.MariaDB [(none)]> CREATE DATABASE heat;
Query OK, 1 row affected (0.000 sec)MariaDB [(none)]> GRANT ALL PRIVILEGES ON heat.* TO 'heat'@'localhost' IDENTIFIED BY 'HEAT_DBPASS';
Query OK, 0 rows affected (0.003 sec)MariaDB [(none)]> GRANT ALL PRIVILEGES ON heat.* TO 'heat'@'%' IDENTIFIED BY 'HEAT_DBPASS';
Query OK, 0 rows affected (0.002 sec)MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.001 sec)MariaDB [(none)]> exit;
Bye

11.1.2 获取管理员凭证

[root@xgk-ctl ~]# source /etc/keystone/admin-openrc 

11.1.3 创建服务凭证

| enabled             | True                             |
| id                  | f26db66f89bd47f59505656466c77f83 |
| name                | heat_domain_admin                |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

3、为heat_domain_admin用户添加管理员角色

[root@xgk-ctl ~]# openstack role add --domain heat --user-domain heat --user heat_domain_admin admin

4、创建heat_stack_owner角色

[root@xgk-ctl ~]# openstack role create heat_stack_owner
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | None                             |
| domain_id   | None                             |
| id          | e617519a4dab4e77898260a25a5a3d84 |
| name        | heat_stack_owner                 |
| options     | {}                               |
+-------------+----------------------------------+

5、将heat_stack_owner角色添加到演示项目和用户，以启用演示用户的栈管理

[root@xgk-ctl ~]# openstack role add --project myproject --user myuser heat_stack_owner

注：必须向管理栈的每个用户添加heat_stack_owner角色。

6、创建heat_stack_user角色

[root@xgk-ctl ~]# openstack role create heat_stack_user
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | None                             |
| domain_id   | None                             |
| id          | c9cee4daa13a4ece9b32a8174314dd91 |
| name        | heat_stack_user                  |
| options     | {}                               |
+-------------+----------------------------------+

注：Orchestration服务自动将heat_stack_user角色分配给它在堆栈部署期间创建的用户。默认情况下，此角色限制API操作。为避免冲突，请勿将此角色添加到具有heat_stack_owner角色的用户。

注：该输出应指示控制节点上的四个heat-engine（默认为4个或主机上的CPU数量，以较大者为准）。

11.4 启动实例

11.4.1 创建模板

用以下内容创建一个名为demo-template.yml的模板文件

[root@xgk-ctl ~]# vim demo-template.yml
heat_template_version: 2015-10-15
description: Launch a basic instance with CirrOS image using the``m1.nano`` flavor, ``mykey`` key,  and one network.parameters:NetID:type: stringdescription: Network ID to use for the instance.resources:server:type: OS::Nova::Serverproperties:image: cirrosflavor: m1.nanokey_name: mykeynetworks:- network: { get_param: NetID }outputs:instance_name:description: Name of the instance.value: { get_attr: [ server, name ] }instance_ip:description: IP address of the instance.value: { get_attr: [ server, first_address ] }

11.4.2 创建栈

使用demo-template.yml模板创建栈

1、获取管理员租户凭证

[root@xgk-ctl ~]# source /etc/keystone/admin-openrc

2 、确定可用网络

[root@xgk-ctl ~]# openstack network list
+--------------------------------------+-----------+--------------------------------------+
| ID                                   | Name      | Subnets                              |
+--------------------------------------+-----------+--------------------------------------+
| b3466904-386b-4741-8cab-724713bab263 | provider  | 25e1f3c1-340a-420c-8cea-030229bbc2f5 |
+--------------------------------------+-----------+--------------------------------------+

3、设置NET_ID环境变量以反映网络的ID。例如，使用提供商网络

[root@xgk-ctl ~]# export NET_ID=$(openstack network list | awk '/ provider / { print $2 }')
[root@xgk-ctl ~]# echo $NET_ID
b3466904-386b-4741-8cab-724713bab263

4、在提供商网络上创建一个CirOS实例的栈

[root@xgk-ctl ~]# openstack stack create -t demo-template.yml --parameter "NetID=$NET_ID" stack
+---------------------+----------------------------------------------------------------------------------------------------------+
| Field               | Value                                                                                                    |
+---------------------+----------------------------------------------------------------------------------------------------------+
| id                  | b7d8e940-4874-4a69-b3b3-aff8dbc7b4ae                                                                     |
| stack_name          | stack                                                                                                    |
| description         | Launch a basic instance with CirrOS image using the ``m1.nano`` flavor, ``mykey`` key,  and one network. |
| creation_time       | 2023-02-15T13:25:06Z                                                                                     |
| updated_time        | None                                                                                                     |
| stack_status        | CREATE_IN_PROGRESS                                                                                       |
| stack_status_reason | Stack CREATE started                                                                                     |
+---------------------+----------------------------------------------------------------------------------------------------------+

5、稍等片刻后，验证是否成功创建栈

[root@xgk-ctl ~]# openstack stack list
+--------------------------------------+------------+----------------------------------+-----------------+----------------------+--------------+
| ID                                   | Stack Name | Project                          | Stack Status    | Creation Time        | Updated Time |
+--------------------------------------+------------+----------------------------------+-----------------+----------------------+--------------+
| b7d8e940-4874-4a69-b3b3-aff8dbc7b4ae | stack      | 34da8f5ef8cd42cdb521ee6ebc4003c4 | CREATE_COMPLETE | 2023-02-15T13:25:06Z | None         |
+--------------------------------------+------------+----------------------------------+-----------------+----------------------+--------------+

6、显示实例的名称和IP地址

[root@xgk-ctl ~]# openstack stack output show --all stack
+---------------+--------------------------------------------------+
| Field         | Value                                            |
+---------------+--------------------------------------------------+
| instance_ip   | {                                                |
|               |   "output_key": "instance_ip",                   |
|               |   "description": "IP address of the instance.",  |
|               |   "output_value": "192.168.218.64"               |
|               | }                                                |
| instance_name | {                                                |
|               |   "output_key": "instance_name",                 |
|               |   "description": "Name of the instance.",        |
|               |   "output_value": "stack-server-heq4ngu7r4s7"    |
|               | }                                                |
+---------------+--------------------------------------------------+

7、与OpenStack客户端的输出进行比较

[root@xgk-ctl ~]# openstack server list
+--------------------------------------+---------------------------+--------+--------------------------+--------------------------+---------+
| ID                                   | Name                      | Status | Networks                 | Image                    | Flavor  |
+--------------------------------------+---------------------------+--------+--------------------------+--------------------------+---------+
| cff38d1a-358b-4852-b14b-5d3425e4c6bc | stack-server-heq4ngu7r4s7 | ACTIVE | provider=192.168.218.64  | cirros                   | m1.nano |
| f482988e-665e-4374-90a7-e8416a835604 | provider-instance         | ACTIVE | provider=192.168.218.24  | cirros                   | m1.nano |
+--------------------------------------+---------------------------+--------+--------------------------+--------------------------+---------+

8、删除栈

创建的栈不再需要时，可以将其删除。

[root@xgk-ctl ~]# openstack stack delete --yes stack
