一、需求说明
最近一直在学习mysql-mmm，想以后这个架构也能用在我们公司的业务上，我们公司的业务是单机多实例部署，所以也想把mysql-mmm部署成这样，功夫不负有心人，我成功了，和大家分享一下：
二、环境说明
| 集群 | 角色 | 主机名 | IP | Mysql Port | Server ID | VIP Writer | VIP READER |
| navy2 | Agent | db1 | 172.28.26.101 | 3307 | 11 | 172.28.26.107 | ? |

PS：db1和db2上分别有两个库navy2和navy3，互为主主，172.28.26.107是navy2的写入虚拟IP，172.28.26.108是navy2的读虚拟IP，172.28.26.109是navy2的写入虚拟IP，172.28.26.110是navy3的读虚拟IP。
三、部署
1、mysql和mysql-mmm的安装及mysql的主从配置请查看前面的博文：http://navyaijm.blog.51cto.com/4647068/1230674，这里只介绍mmm多实例配置。
2、db1上：
