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，根据cpu核数设定；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。
report-host：
The host name or IP address of the slave to be reported to the master during slave registration. This value appears in the output of SHOW SLAVE HOSTS on the master server.
report-port:
The TCP/IP port number for connecting to the slave, to be reported to the master during slave registration.
master-info-repository:
The setting of this variable determines whether the slave logs master status and connection information to a FILE (master.info), or to a TABLE (mysql.slave_master_info)
relay-log-info-repository：
This option causes the server to log its relay log info to a file or a table.
log_slave_updates：
Whether updates received by a slave server from a master server should be logged to the slave's own binary log. Binary logging must be enabled on the slave for this variable to have any effect.
