读取上游 502 Bad GateWay 的响应标头时上游过早关闭连接

nginx 正在杀死我..所以现在我遇到了 502 Bad Gateway。错误日志显示：

2016/10/12 17:39:53 [info] 3023#0: *464 client closed connection while waiting for request, client: 127.0.0.1, server: 0.0.0.0:443

我的 ngninx conf 文件现在如下所示：

我不知道我做错了什么...有人能帮助我吗

你们的申请需要多长时间才能得到回复？

当客户端连接超时时，我们会看到类似以下的错误：

2016/10/12 17:39:53 [info] 3023#0: *465 client closed connection while waiting for request, client: 127.0.0.1, server: 0.0.0.0:443

例如，如果 varnish 实例在 10 秒时超时，而 nginx 愿意等待 30 秒以获得 PHP 响应，则 varnish 将在 Nginx 响应之前终止连接。

错误upstream prematurely closed connection可能是 nginx 终止与 PHP 的连接。我不太确定，因为我不记得处理过这个错误！

希望这对 OP 有帮助 :)
