我的 phpmyadmin 有一个非常烦人的问题。它出乎意料地出现。据我所知，我的专用服务器没有发生任何变化。
当我尝试在浏览器中执行任何查询或显示需要超过 1 秒执行的视图时（Windows 7 上的 Firefox，即行为相同），我收到以下错误：
Error in Processing Request
Error code: 504
Error text: Gateway Timeout
查询可以或不需要有 count(*)。他们在 5m - 50m 行的表上工作。
有时，当我单击 phpmyadmin 中的任何链接（例如“浏览”、“服务器”或“结构”）时，会出现相同的错误。
在同一个专用服务器上运行更密集的查询的 php 脚本可以完美地工作。
以下是一些技术细节：
Database server
•Server: Localhost via UNIX socket
•Server type: MySQL
•Server version: 5.5.38-0ubuntu0.14.04.1-log - (Ubuntu)
•Protocol version: 10
•User: XXX@localhost
• Server charset: UTF-8 Unicode (utf8)
Web server
•Apache/2.4.7 (Ubuntu)
•Database client version: libmysql - 5.5.38
•PHP extension: mysqli Documentation
phpMyAdmin
•Version information: 4.2.3deb1.trusty~ppa.1
我在网上跟踪了一些线索，尝试在我的conf.inc.php文件中添加最后两行（见下文），但没有任何更改，在重新启动服务器后也是如此：
<?php

*
* This file overrides the settings made by phpMyAdmin interactive setup
* utility.

* For example configuration see

请帮助我。
我将以下行添加到文件 /etc/nginx/nginx.conf 的 http{} 块中：
重启nginx
祝你好运！！！记得喜欢我哦。非常感谢你！
最后，我发现这不是我的服务器上的问题，但我当前的互联网连接提供商只是取消（发送此错误消息）所有需要 10 秒以上才能完成的 https 请求。
也许你可以检查或增加 /etc/nginx/ngix.conf 中的 nginx 超时设置？检查 proxy_send_timeout 和 proxy_read_timeout。
