备注：conf/htpasswd 文档的内容用 apache 提供的 htpasswd 工具来产生即可.

查看 Nginx 运行状态 输入地址http://192.168.8.1/NginxStatus/ 。输入验证帐号密码，即可看到类似如下内容：

       Active connections: 328   <br>       server accepts handled requests   <br>       9309 8982 28890   <br>       Reading: 1 Writing: 3 Waiting: 324  

第一行表示现在活跃的连接数，第三行的第三个数字表示Nginx运行着。
