在主从中使用gtid

确认my.cnf中有如下参数：

binlog_format=row
gtid_mode = on
enforce_gtid_consistency = on
log-slave-updates = 1
skip_slave_start = 1

确认复制用的参数及密码

grant replication slave on *.* to  rep@'192.168.56.%' identified by 'pwd4rep';
flush privileges;

新库中直接使用gtid同步

change master to
master_host='192.168.56.3',
master_port=3306,
master_user='rep',
master_password='pwd4rep',
master_auto_position=1;
start slave;
show slave status \G
