你好，你能帮我吗？我正在尝试在我的 ubuntu 16.04 服务器上设置 apache 和 nginx 服务器，但是当我尝试访问 localhost/info.php 时，我得到了
502 错误网关 nginx/1.9.15 (Ubuntu)
错误 502 错误网关，这是来自错误日志文件：
2017/01/24 10:50:55 [错误] 14774#14774：*29 connect() 连接到上游时失败（111：连接被拒绝），客户端：127.0.0.1，服务器：example.com，请求：“GET /info.php HTTP/1.1”，上游：“http://127.0.0.1:8080/info.php"，主机：“localhost”

经过两天的时间，我终于解决了我的问题。多亏了这个页
我最终删除了该/etc/nginx/sites-available/default文件并且只剩下一个 apache 文件。
127.0.0.1如果您仅尝试为本地环境进行设置，则只需按照页面上的说明输入您的 IP 地址即可。
您也可以跳过第 8 部分并按照其他部分操作，因为您不需要它们。这些用于设置，以便您的服务器/com 可以在我们的网络之外可见，因此称为 - Internet :)
