使用 gtid进行主从复制

郑全

环境：

 

   192.168.0.15  主

   192.168.0.16  从

 

配置，

    主库/etc/my.cnf需要设置

      gtid_mode=on
     enforce_gtid_consistency=true
     log_slave_updates=true

 

    然后重启主服务器

     service mysqld restart

 

    从库设置 /etc/my.cnf

      gtid_mode=on
     enforce_gtid_consistency=true
     log_slave_updates=true

    并重启 从库

 

    在从库执行：

     change master to master_host='192.168.0.15', master_user='repuser',master_password='123',master_auto_position=1;

 

    之后，启动 start slave

    最后，检查show slave status \G

 

    mysql> show slave status\G
