稍后一点... ;)

What are you calling "easier" ? There is pretty much solutions with MySQL :

• MySQL Cluster, with NDB Engine (High availability solution but some limitations : no foreign keys)
• MySQL Master / Slave with their own replication system
• MySQL replicated via DRBD and heartbeat.

There is a lot of material on this subject : Failover support for a DB and even more here : Scaling solutions for MySQL (Replication, Clustering)

MySQL集群是一种即插即用的解决方案，但复制的设置并不难。

问候。

实际的故障转移位可以通过心跳来管理（Linux HA项目的一部分；http://linux-ha.org/），我被告知MySQL企业套件中有些工具可以帮助管理复制，尽管我从未自己使用过。
