授权问题!这是什么情况？有权限读 写不进去 ，直接在mysql-master 上操作可以正常写。

如果做针对网段来如(grant all privileges on . to root@"192.168.100.0/24" identified by '1234'; )做授权然后作写操作就以下报错： 2017-11-21 09:13:08: (warning) (libevent) event_del: event has no event_base set. 2017-11-21 09:13:08: (critical) last message repeated 1 times 2017-11-21 09:13:08: (critical) proxy-plugin.c.1450: I have no server backend, closing connection 2017-11-21 09:13:08: (critical) network-mysqld.c.1387: plugin_call(CON_STATE_READ_QUERY) failed 以上是报错提示，版本是2.2.1 ！ 莫非必须是%嘛？
