[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:[email protected]/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
mysql> use heat Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> show tables; +---------------------+ | Tables_in_heat | +---------------------+ | event | | migrate_version | | raw_template | | resource | | resource_data | | software_config | | software_deployment | | stack | | stack_lock | | user_creds | | watch_data | | watch_rule | +---------------------+ 12 rows in set (0.00 sec)
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
7、keystone注册用户
keystone user-create --name=heat --pass=heat4smtest [email protected]
sm@controller:~$ keystone user-create --name=heat --pass=heat4smtest [email protected] +----------+----------------------------------+ | Property | Value | +----------+----------------------------------+ | email | [email protected] | | 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

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。

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
