导出的sql文件会记录GTID的值
SET @@GLOBAL.GTID_PURGED='2969720f-96e7-11e7-b033-92156d0584a5:1-25988615';
在主库上创建用来做同步的账户
CREATE USER 'repl'@'192.168.0.2' IDENTIFIED BY '密码'; #192.168.0.2 为从库的地址
GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.0.2'; #添加权限
FLUSH PRIVILEGES; #刷新权限，立马生效
拷贝导出的sql文件到从库本地
重置从库的GTID值
reset master;
在从库上导入数据
source /root/master-20190508-1.sql;
导入完成后在从库开始配置
change master to master_host = '192.168.0.1', master_port = 3306 ,master_user = 'repl', master_password='密码',master_auto_position=1;
启动同步进程
start slave;
查看状态
show slave statusG
