这个是因为只对后端做了tcp连接性检查，没有和后端进行mysql协议交互造成的。
如果针对mysql协议层进行检查，是否需要真正登录成功才可以？这样的话需要在nginx配置中暴露myql用户名密码，又会带来安全问题。
上一个issue #32 中提到的host_cache_size = 0 是不是可以规避此问题？

host_cache_size = 0 只能规避nginx IP不会被block，但是如果5.7.19默认的日志级别不调整的话，还是会输出很多note错误信息到mysql错误日志中，现在我这边是把mysql的日志级别从默认的3调到2了，log_error_verbosity=2，我的版本是5.7.19，我看了官方文档，不同的版本这个默认日志级别是不一样的

关闭host_cache_size就像上面说的，只能规避IP不会被block,但是日志会输出很多，如果是开发就没办法了，线上的话要调整日志输出
