十二、Openstack编排服务（heat）

简单介绍：

heat主要有四个组件：heat-api、[b]heat-engine、[b]heat-api-cfn[/b][/b]

[b]heat-api：一个OpenStack本地
REST API ,发送API请求到heat-engine，通过远程过程调用(RPC)[/b]

[b]heat-api-cfn：AWS
队列API，和AWS CloudFormation兼容，发送API请求到heat-engine，通过远程过程调用
[/b]

[b]heat-engine：启动模板和提供给API消费者回馈事件[/b]

控制节点上

1.进入SQL创建heat数据库并授予权限

mysql -uroot -p


CREATE DATABASE heat;

GRANT ALL PRIVILEGES ON heat.* TO 'heat'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON heat.* TO 'heat'@'%' IDENTIFIED BY '123456';


2.创建heat用户

需要管理员权限

. admin-openrc

openstack user create --domain default --password-prompt heat

[root@controller ~]# . admin-openrc
[root@controller ~]# openstack user create --domain default --password-prompt heat
User Password:
Repeat User Password:
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | b24b3093654b4ba4be706fe675a03b2d |
| enabled   | True                             |
| id        | 7237d6802d0142d498f70b26587cfd8a |
| name      | heat                             |
+-----------+----------------------------------+


3.添加 admin 角色到 heat 用户上

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

此操作无返回

4.创建heat
和 heat-cfn 服务实体

heat

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

[root@controller ~]# openstack service create --name heat --description "Orchestration" orchestration
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | Orchestration                    |
| enabled     | Tr
102f6
ue                             |
| id          | ecbbbee759b6422c89c2b6eb6962133f |
| name        | heat                             |
| type        | orchestration                    |
+-------------+----------------------------------+

heat-cfn

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

[root@controller ~]# openstack service create --name heat-cfn --description "Orchestration"  cloudformation
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | Orchestration                    |
| enabled     | True                             |
| id          | 06b223ae69444ad6abc5a6c1c6a72993 |
| name        | heat-cfn                         |

| name      | heat_stack_owner                 |
+-----------+----------------------------------+


11.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

此操作无返回

12.创建 heat_stack_user 角色

openstack role create heat_stack_user

[root@controller ~]# openstack role create heat_stack_user

| name      | heat_stack_user                  |
+-----------+----------------------------------+


安装配置：

1.安装软件包

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


2.修改配置文件/etc/heat/heat.conf

vi /etc/heat/heat.conf

[DEFAULT]
rpc_backend = rabbit#启用消息队列
heat_metadata_server_url = http://controller:8000#配置元数据 heat_waitcondition_server_url = http://controller:8000/v1/waitcondition#配置URLserver #配置栈域与管理凭据
stack_domain_admin = heat_domain_admin#具有足够管理用户和项目功能的用户
stack_domain_admin_password = 123456#(heat_domain_admin用户选择密码）
stack_user_domain_name = heat#包含heat的域

配置数据库访问

[database]
connection = mysql+pymysql://heat:123456@controller/heat

配置消息队列

[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = 123456

配置认证服务访问（都是heat的密码）

[keystone_authtoken]#没有这个自己添加在配置文件最下面
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 = 123456

[trustee]
auth_plugin = password#要加载的插件的名称
auth_url = http://controller:35357#认证的URL username = heat#用户名
password = 123456#密码
user_domain_name = default#域

[clients_keystone]
auth_uri = http://controller:35357#没有版本的URL 
[ec2authtoken]
auth_uri = http://controller:5000/v2.0#认证的端点的URI


3.同步Orchestration数据库

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

[root@controller ~]# vi /etc/heat/heat.conf
[root@controller ~]# su -s /bin/sh -c "heat-manage db_sync" heat
2017-11-16 11:08:46.484 17785 INFO migrate.versioning.api [-] 27 -> 28...

完成安装：

启动 Orchestration 服务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 start openstack-heat-api.service openstack-heat-api-cfn.service openstack-heat-engine.service

[root@controller ~]# systemctl enable openstack-heat-api.service openstack-heat-api-cfn.service openstack-heat-engine.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-heat-api.service to /usr/lib/systemd/system/openstack-heat-api.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-heat-api-cfn.service to /usr/lib/systemd/system/openstack-heat-api-cfn.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-heat-engine.service to /usr/lib/systemd/system/openstack-heat-engine.service.

[root@controller ~]# systemctl start openstack-heat-api.service openstack-heat-api-cfn.service openstack-heat-engine.service


验证：

使用管理员权限

. admin-openrc
列出服务组件，以验证是否成功启动并注册了每个进程
openstack orchestration service list

[root@controller ~]# . admin-openrc
[root@controller ~]# openstack orchestration service list
