[部署篇12]VMWare搭建Openstack——控制节点的heat的安装

部署编排 (Orchestration)：Heat。提供了一种通过模板定义的协同部署方式，实现云基础设施软件运行环境（计算、存储和网络资源）的自动化部署。自Havana版本集成到项目中。

Heat是OpenStack的负责编排计划的主要项目。它可以基于模板来实现云环境中资源的初始化，依赖关系处理，部署等基本操作，也可以解决自动收缩,负载均衡等高级特性。目前Heat自身的模板格式(HOT)正在不停的改进，同时也支持AWS CloudFormation 模板(CFN),HOT的目标是在不远的将来可以完全的替代CFN。

Heat提供了一个OpenStack的原生REST API和CloudFormation兼容的查询API。

Heat的工作原理

Heat主要是基于模板文件对应用进行管理，在模板文件中可以定义应用需要的资源，资源可以包括多种类型（CFN以及HOT支持的资源类型可能会存在一定的差别）例如IP,网络，镜像，用户，实例等。定义资源的同时也可以指定资源之间的依赖关系，例如使用云硬盘创建创建一个实例时，可以指定在创建实例时必须要创建云硬盘。

编辑完模板文件后，可以使用该模板文件创建Stack,创建的过程中Heat引擎会根据模板文件中定义的资源，调用对应的资源插件创建资源。创建完Stack之后，Heat可以管理Stack中所有资源的生命周期,例如可以删除资源，也可以通过更新模板的方式来更新Stack中资源的定义。

安装步骤

库名: heat
账户: heat
密码: heat4smtest

1、安装软件包

sudo apt-get install heat-api heat-api-cfn heat-engine

2、修改heat配置文件

sudo vi /etc/heat/heat.conf

[database]
# The SQLAlchemy connection string used to connect to the database
connection = mysql://heat:heat4smtest@192.168.3.180/heat

3、sudo rm /var/lib/heat/heat.sqlite

4、创建数据库、账户并配置权限

sudo mysql -uroot -p#db4smtest# -e 'CREATE DATABASE heat;'

sudo mysql -uroot -p#db4smtest# -e 'CREATE USER heat;'

sudo mysql -uroot -p#db4smtest# -e "GRANT ALL PRIVILEGES ON heat.* TO 'heat'@'localhost' IDENTIFIED BY 'heat4smtest';"

sudo mysql -uroot -p#db4smtest# -e "GRANT ALL PRIVILEGES ON heat.* TO 'heat'@'%' IDENTIFIED BY 'heat4smtest';"

sudo mysql -uroot -p#db4smtest# -e "SET PASSWORD FOR 'heat'@'%' = PASSWORD('heat4smtest');"

5、创建heat数据表，可能会出现错误，但是无需理会

sudo heat-manage db_sync

sm@controller:~$ sudo heat-manage db_sync
No handlers could be found for logger "heat.common.config"
2015-05-17 01:53:41.853 24843 WARNING heat.openstack.common.db.sqlalchemy.session [-] This application has not enabled MySQL traditional mode, which means silent data corruption may occur. Please encourage the application developers to enable this mode./usr/lib/python2.7/dist-packages/sqlalchemy/engine/default.py:324: Warning: Specified key was too long; max key length is 767 bytes cursor.execute(statement, parameters)

查看是否创建了表

6、编辑heat配置文件

sudo vi /etc/heat/heat.conf

[DEFAULT]
verbose = True
log_dir=/var/log/heat

rabbit_host = 192.168.3.180
rabbit_password = mq4smtest

# URL of the Heat metadata server. (string value)
heat_metadata_server_url = http://192.168.3.180:8000 # URL of the Heat waitcondition server. (string value)
heat_waitcondition_server_url = http://192.168.3.180:8000/v1/waitcondition 
[keystone_authtoken]
auth_host = 192.168.3.180
auth_port = 35357
auth_protocol = http
auth_uri = http://192.168.3.180:5000/v2.0 admin_tenant_name = service
admin_user = heat
admin_password = heat4smtest
[ec2authtoken]
auth_uri = http://192.168.3.180:5000/v2.0[/code] 
7、keystone注册用户

keystone user-create --name=heat --pass=heat4smtest --email=heat@163.com
sm@controller:~$ keystone user-create --name=heat --pass=heat4smtest --email=heat@163.com
+----------+----------------------------------+
| Property |              Value               |

| enabled  |               True               |
|    id    | 356986370fa0486d972b0ff84f068a02 |
|   name   |               heat               |
| username |               heat               |
+----------+----------------------------------+


keystone注册用户角色

keystone user-role-add --user=heat --tenant=service --role=admin

8、keystone创建heat服务

keystone service-create --name=heat --type=orchestration --description="Orchestration"
sm@controller:~$ keystone service-create --name=heat --type=orchestration --description="Orchestration"
+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+

keystone创建heat-cfn服务

keystone service-create --name=heat-cfn --type=cloudformation --description="Orchestration CloudFormation"
sm@controller:~$ keystone service-create --name=heat-cfn --type=cloudformation --description="Orchestration CloudFormation"
+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+
| description |   Orchestration CloudFormation   |

|  service_id | 5764a2c064f5435c8f43f38c3ddb455d |
+-------------+----------------------------------+


9、keystone创建角色

keystone role-create --name heat_stack_user
sm@controller:~$ keystone role-create --name heat_stack_user
+----------+----------------------------------+
| Property |              Value               |
+----------+----------------------------------+
|    id    | 5ae818372ea24d2589e5c19b299c2e6a |
|   name   |         heat_stack_user          |
+----------+----------------------------------+


10、启动服务

sudo service heat-api restart

sudo service heat-api-cfn restart

sudo service heat-engine restart

测试
1、模板文件

这是帮助给的一个模板文件，创建test-stack.yml

heat_template_version: 2013-05-23
description: Test Template
parameters:
  ImageID:
    type: string
    description: Image use to boot a server
  NetID:
    type: string
    description: Network ID for the server
resources:
  server1:
    type: OS::Nova::Server
    properties:
      name: "Test server"
      image: { get_param: ImageID }
      flavor: "m1.tiny"
      networks:
      - network: { get_param: NetID }
outputs:
  server1_private_ip:
    description: IP address of the server in the private network
    value: { get_attr: [ server1, first_address ] }


2、该模板文件目的就是创建一个VM实例，需要获得镜像信息和网络信息

sm@controller:~$ neutron net-list
+--------------------------------------+------------+-----------------------------------------------------+
| id                                   | name       | subnets                                             |
+--------------------------------------+------------+-----------------------------------------------------+
| 1dfa9da1-43fd-4128-b9a0-2ca76a664933 | sharednet1 | db1aad02-3890-44d4-93c4-c933c2c818a5 192.168.3.0/24 |
+--------------------------------------+------------+-----------------------------------------------------+


执行该模板，输入条件信息

sm@controller:~$ heat stack-create -f /home/sm/test-stack.yml -P "ImageID=cirros-0.3.2-x86_64;NetID=1dfa9da1-43fd-4128-b9a0-2ca76a664933" testStack
+--------------------------------------+------------+--------------------+----------------------+
| id                                   | stack_name | stack_status       | creation_time        |
+--------------------------------------+------------+--------------------+----------------------+
| 52be000d-4046-40e9-9bab-d11375162080 | testStack  | CREATE_IN_PROGRESS | 2015-05-16T19:17:21Z |
+--------------------------------------+------------+--------------------+----------------------+


查看heat栈信息

sm@controller:~$  heat stack-list
+--------------------------------------+------------+-----------------+----------------------+
| id                                   | stack_name | stack_status    | creation_time        |
+--------------------------------------+------------+-----------------+----------------------+
| 52be000d-4046-40e9-9bab-d11375162080 | testStack  | CREATE_COMPLETE | 2015-05-16T19:17:21Z |
+--------------------------------------+------------+-----------------+----------------------+


我们进入horzion查看信息

我们看到项目，增加了一个编配栏，里面包含一个栈，就是我们刚才创建的testStack。



点击该信息



我们可以看到，创建的明细，新生成了一个192.168.3.125的VM实例

我们再查看实例
