ubuntu 重启 nginx 失败，* Restarting nginx nginx ...fail!，nginx...fail

执行 nginx 重启服务时，提示失败如下：

$ sudo service nginx restart 
 * Restarting nginx nginx
   ...fail!

原因是你配置 nginx 的配置文件出了错误

查找错误，处理方法：

 $ sudo nginx -t
 nginx: [emerg] "location" directive is not allowed
 here in /etc/nginx/nginx.conf:11
 nginx: configuration file /etc/nginx/nginx.conf
 test failed

根据错误信息，修改对应生的配置文件即可。
