As this works fine, it would be nicer for the clients to ask for the time from the cluster and use that when inserting or updating records which need current timestamp. Maybe the Arbitrator could provide this information, or the Master data node through an event.. These machines should be...

MySQL主从同步至少需要用到2台服务器,一台为master库,另一台为slave库,要实现复制首先需要在master上开启bin-log日志功能,bin-log日志用于记录在Master库中执行的增、删、修改、更新操作的sql语句,整个过程需要开启3个线程,分别是Master开启IO线程,Slave开启IO线程和SQL线程。
