上边这些基本都是优化项：
server-id=1
log-bin = mysql-bin
#log-bin=mysql-bin.log
#binlog-do-db =microcosm --binlog-do-db：指定mysql的binlog日志记录哪个db
#replicate-do-db =microcosm
binlog-ignore-db=mysql
replicate-ignore-db=mysql
default-storage-engine=INNODB
Replicate_Do_DB：参数是在slave上配置，指定slave要复制哪个库
在master上设置binlog_do_弊端：
1、过滤操作带来的负载都在master上
2、无法做基于时间点的复制（利用binlog）。
