配置前提
要在MySQL 5.6中使用复制功能，其服务配置段[mysqld]中于少应该定义如下选项：
- binlog-format：二进制日志的格式，有row、statement和mixed几种类型；
- 需要注意的是：当设置隔离级别为READ-COMMITED必须设置二进制日志格式为ROW，现在MySQL官方认为STATEMENT这个已经不再适合继续使用；但mixed类型在默认的事务隔离级别下，可能会导致主从数据不一致；
- log-slave-updates、gtid-mode、enforce-gtid-consistency、report-port和report-host：用于启动GTID及满足附属的其它需求；
- master-info-repository和relay-log-info-repository：启用此两项，可用于实现在崩溃时保证二进制及从服务器安全的功能；
- sync-master-info：启用之可确保无信息丢失；
- slave-paralles-workers：设定从服务器的SQL线程数；0表示关闭多线程复制功能；
- binlog-checksum、master-verify-checksum和slave-sql-verify-checksum：启用复制有关的所有校验功能；
- binlog-rows-query-log-events：启用之可用于在二进制日志记录事件相关的信息，可降低故障排除的复杂度；
- log-bin：启用二进制日志，这是保证复制功能的基本前提；
- server-id：同一个复制拓扑中的所有服务器的id号必须惟一；
