使用 CREATE USER 'slave'@'%' IDENTIFIED WITH mysql_native_password BY '123456'; 创建slave用户并配置123456密码时，使用了WITH mysql_native_password参数，表示直接可以使用密码进行连接，不然的话后面在从mysql中直接使用密码进行连接会出问题
（3）master_log_file='mysql-bin.000001', master_log_pos=608 要和对应的主mysql一致，进入到自己的主MySQL使用 show master status\G 查看
执行连接，然后再使用 start slave 命令启动主从复制服务 再使用 show slave status\G 查看状态
