2,授权复制帐号和测试帐号(sysbench做测试)
GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'repl'@'172.31.%' IDENTIFIED BY 'repl';
grant select,create,index,insert,update,delete,drop on *.* to hatest@'172.31.%' identified by '123456';
flush privileges;
6,此时连mysql的时候会报错,管理后台显示该实例正在修复中
$ mysql -uroot -p -hmasterfailovertest.cojn00n8zy2d.us-east-1.rds.amazonaws.com
ERROR 2003 (HY000): Can't connect to MySQL server on 'masterfailovertest.cojn00n8zy2d.us-east-1.rds.amazonaws.com' (110)
7,查看slave的复制状态是否正常。
>show slave status\G

1 row in set (0.00 sec) 多次执行show slave status\G命令发现复制状态都显示正常,但是位置一直卡在mysql-bin-changelog.000024 24121968这里不动,此时RDS上面的主库一直有用sysbench写数据进来。可以断定虽然复现状态显示正常,但是其实连接已经失效。
