实际上,MySQL并不支持其它一些DBMS支持的多主服务器复制(Multimaster Replication),这是MySQL的复制功能很大的一个限制(多主服务器的难点在于解决更新冲突),但是,如果你实在有这种需求,你可以采用MySQL Cluster,以及将Cluster和Replication结合起来,可以建立强大的高性能的数据库平台。但是,可以通过其它一些方式来模拟这种多...

Hint:You should avoid using referential integrity in aMaster-Master Replicationscenario because it can give you major problems. You must ensure that the replication data is written to the databases without side effects, such as double updates due to referential integrity. This is very complex when...
The replication unit should not be the complete replication set or complete tables for a master-master replication. Conflicts During a transmission, special care has to be taken before the acquired and manipulated data is written to the target. Because the target can also be written to by ...

“master-slave” replication, is a typical setup. Our setup will be better than that, because master-master replication allows data to be copied from either server to the other one. This subtle but important difference allows us to perform mysql read or writes from either server. This ...
Master-Master allows writing to both, and, hence, provides no way to make changes during the replication, at least not bi-directionally. Master-Slave does allow limited flexibility, such as different engine, different indexes, and, in a few cases, different datatypes. However, you could lose...
