MHA架构
http://code.google.com/p/mysql-master-ha/
to monitor MySQL master in an existing replication environment, detecting master failure, and doing master failover automatically.
MHA automatically identifies differential relay log events from the latest slave, and applies differential events to other slaves. So all slaves can be consistent.

" DeNA公司在150+主从环境中用MHA。当其中一个master崩溃,MHA4秒完成故障转移,这是主动/被动集群解决方案无法完成的。" |
