在这里详细讲解healthcheck_nginx_upstreams模块中存在的bug，对于healthcheck_nginx_upstreams模块的安装和使用请阅读上一篇blog进行学习。

测试环境，通过nginx做反向代理，请求转发给2和3：

1.192.168.0.235(nginx)

2.192.168.30.150(apache)

3.192.168.30.200(apache)

遇到的问题，当我用上一篇blog的方法安装了healthcheck_nginx_upstreams，并且配置nginx如下：

worker_processes 5;

#daemon off;

events {

  worker_connections 1000;

}

# Only if you want to see lots of spam

error_log logs/error.log debug_http;

http {

  upstream test_upstreams {

    server 192.168.30.150:80;

    server 192.168.30.200:80;

    healthcheck_enabled;

    healthcheck_delay 2000;

    healthcheck_timeout 1000;

    healthcheck_failcount 1;

    healthcheck_send "GET /.health HTTP/1.0";

  }

  server {

    listen 12389;

    location / {

      proxy_set_header Host $http_host;

      proxy_set_header X-Real-IP $remote_addr;

      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      proxy_pass http://test_upstreams;

      proxy_connect_timeout 3;

    }

    location /stat {

      healthcheck_status;

    }

  }

}
