MySQL5.7.24 version of
CentOS release 6.5
note:
MySQL5.7 Slave version can not open binlog, you can save this part of the disk I / O consumption, and MySQL5.6 version must be turned binlog, because GTID information needs in the binlog stores (log_slave_updates), open only to use GTID the binlog Features. MySQL5.7 version information recorded GITD (mysql.gtid_executed) by GTID system tables, each transaction commits, the message is inserted into the table GTID
Master配置：
