MySQL 5.7 开启主从同步开启GTID恢复数据

1.停掉从库的主从复制。

stop slave;

 2.将主库的数据导出，导出时加上--master-data=2

mysqldump

3.在从库上导入主库导出的数据。

reset slave all;
reset master;
source /opt/JZJ_v1.0_2020-06-12_21_31.sql;

 4.在从库上change master

change master to master_host='10.1.8.73',master_port=3307,master_user='mxxrs',master_password='JZJxxxxxxxxxx',master_auto_position=1;

 5.开启主从复制。

start slave;

 6.查看主从复制状态

mysql> show slave status\G
