OpenStack使用Bosh部署CloudFoundry(八)—部署Mysql服务-V2 Broker

版本说明：

CloudFoundry：V2版本-v149+（本文后续章节中的Manifest适用于149+版本的CF Release）

OpenStack：Grizzly版本+nova-network

Mysql服务现在在CloudFoundry的Github上有独立的工程支持，工程名称：cf-mysql-release，是基于V2 Broker API开发的新版Service，功能相当强大，可以通过Broker对内部或者外部的Mysql数据库进行管理，该服务最新的发布版本为Release-V5，本文介绍下如何使用BOSH部署两个独立的mysql服务，其中一个是纯Broker接口服务，另一个包括Mysql-Server，使用同一个release包，只是yml配置文件有差别。

1、从GitHub上获取并更新代码

git clone https://github.com/cloudfoundry/cf-mysql-release.git
cd cf-mysql-release
./update

2、打Release包并上传到Blob库

方式一：先将release打包成一个压缩包，然后再执行上传命令，如

bosh create release releases/cf-mysql-5.yml

打包完成后，执行：

bosh upload release releases/cf-mysql-5.tgz

方式二：直接通过yml执行上传操作

bosh upload release releases/cf-mysql-5.yml

鉴于国内的网络环境速度慢且不太稳定，建议使用方式一。创建过程中要求输入release名称，这个自己取，本例中为：cf-mysql

3、编写YAML部署文件

Broker & Mysql-Server部署方案：

说明：Bosh创建两个虚拟机实例，cf-mysql和cf-mysql-broker，cf-mysql作为mysql-server的运行和数据存储环境，cf-mysql-broker用于提供管理接口。

Broker Only部署方案：

    instances: 1
    resource_pool: small

        default: [dns, gateway]
    properties:

      services:
      - name: mysql-ex
        id: 44836033-1f54-4087-b7bc-da9652c2a539
        description: MySQL service for application development and testing
        tags:

      mysql_node:
        host: 10.68.19.62
        admin_password: c1oudc0w

properties: {}

说明：Bosh只创建了一个虚拟机实例cf-mysql-broker用于提供管理mysql数据库的接口，本方案中并没有提供mysql-server服务，而是采用外部的mysql数据库，IP:10.68.19.62就是外部mysql数据库的访问地址，而admin_password就是root用户的密码。注意：需要mysql数据库对root用户进行“%”授权，否则不能远程访问。

4、执行部署

Broker & Mysql-Server方案部署：

bosh deployment cf-mysql.yml
bosh deploy

Broker Only 方案部署：

bosh deployment cf-mysql-ex.yml
bosh deploy

部署结果：

bosh vms

Deployment `cf-mysql'

Director task 167

Task 167 done

+-------------------+---------+---------------+--------------------------+
| Job/index         | State   | Resource Pool | IPs                      |
+-------------------+---------+---------------+--------------------------+
| cf-mysql/0        | running | small         | 50.50.0.27, 10.68.19.134 |
| cf-mysql-broker/0 | running | small         | 50.50.0.26               |
+-------------------+---------+---------------+--------------------------+

VMs total: 2
Deployment `cf-mysql-ex'

Director task 168

Task 168 done

+-------------------+---------+---------------+------------+
| Job/index         | State   | Resource Pool | IPs        |
+-------------------+---------+---------------+------------+
| cf-mysql-broker/0 | running | small         | 50.50.0.28 |
+-------------------+---------+---------------+------------+

VMs total: 1

5、注册Mysql-Broker

root@bosh-cli:~# cf add-service-broker mysql
URL> http://50.50.0.26

Username> vsc

Password> c1oudc0w

说明：URL--Mysql-Broker实例的访问地址，IP可以使用bosh vms查看，Username--Broker认证用户，在YAML配置文件中设置，Password--Broker认证用户的密码，在YAML配置文件中设置。

root@bosh-cli:~# cf add-service-broker mysql-ex
URL> http://50.50.0.28

Username> vsc

Password> c1oudc0w

6、配置Service Plan的访问权限

V2 Broker创建后默认没有开放访问权限，所以需要手动打开，先查看Service Plan 的URL

cf curl /v2/service_plans

在输出的JSON数据中找到Service Plan的URL：

"service_plans": [
          {
            "metadata": {
              "guid": "ac75ce76-dfe5-409a-84a2-42a654dd0ff8",
              "url": "/v2/service_plans/ac75ce76-dfe5-409a-84a2-42a654dd0ff8",
              "created_at": "2013-12-20T09:31:08+00:00",
              "updated_at": null
            },
            "entity": {
              "name": "100mb",
              "free": true,
              "description": "Shared MySQL Server, 100mb persistent disk, 40 max concurrent connections",
              "service_guid": "fea49494-0953-4374-a668-3b9593fe14cb",
              "extra": "{\"cost\":0,\"bullets\":[{\"content\":\"Shared MySQL server\"},{\"content\":\"100 MB storage\"},{\"content\":\"40 concurrent connections\"}]}",
              "unique_id": "ab08f1bc-e6fc-4b56-a767-ee0fea6e3f20",
              "public": false,
              "service_url": "/v2/services/fea49494-0953-4374-a668-3b9593fe14cb",
              "service_instances_url": "/v2/service_plans/ac75ce76-dfe5-409a-84a2-42a654dd0ff8/service_instances"
            }
          }
        ]

执行以下语句开放权限：

cf curl PUT /v2/service_plans/ac75ce76-dfe5-409a-84a2-42a654dd0ff8 -b '{"public":'true'}'

说明：mysql-ex同理操作

7、创建Mysql和Mysql-ex服务

root@bosh-cli:~# cf create-service
1: blob 0.51
2: elasticsearch 0.20
3: memcached 1.4
4: mongodb 2.2
5: mysql , via
6: mysql-ex , via
7: postgresql 9.3
8: rabbitmq 3.0
9: redis 2.6
10: user-provided , via
What kind?> 5

Name?> mysql-166e6

1: default: Shared MySQL Server, 100mb persistent disk, 40 max concurrent connections
Which plan?> 1

Creating service mysql-166e6... OK

root@bosh-cli:~# cf create-service
1: blob 0.51
2: elasticsearch 0.20
3: memcached 1.4
4: mongodb 2.2
5: mysql , via
6: mysql-ex , via
7: postgresql 9.3
8: rabbitmq 3.0
9: redis 2.6
10: user-provided , via
What kind?> 6

Name?> mysql-ex-5a8a7

1: default: Shared MySQL Server, 100mb persistent disk, 40 max concurrent connections
Which plan?> 1

Creating service mysql-ex-5a8a7... OK

服务创建完毕，可以绑定到具体的应用APP上进行使用。
