下面这几个是删除二进制相关的，不作演示，具体可以搜索一下用法：
purge logs to 'log_name';
purge logs before 'date';
reset master;(老版本flush master)
set sql_log_bin=
从服务器上的相关命令:
slave start
slave stop
SLAVE STOP IO_THREAD //此线程把master段的日志写到本地
SLAVE start IO_THREAD
SLAVE STOP SQL_THREAD //此线程把写到本地的日志应用于数据库
SLAVE start SQL_THREAD
reset slave
SET GLOBAL SQL_SLAVE_SKIP_COUNTER
load data from master
show slave status(SUPER,REPLICATION CLIENT)
CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,MASTER_USER=, MASTER_PASSWORD= //动态改变master信息
PURGE MASTER [before 'date'] 删除master端已同步过的日志
