nginx gunicorn django 502 工作者超时仅在某些页面上

nginx gunicorn django 502 工作者超时仅在某些页面上

我使用 gunicorn 和 nginx 配置了一个 django 应用程序，一切都运行良好，直到在服务器上安装 SSL 证书。首先，所有页面都完美呈现，但过了一段时间，一些页面显示 502 错误网关，而其他页面仍然运行良好。

我不是要上传大文件或调用加载时间较长的页面。页面应该立即提供服务。我尝试了所有方法，但找不到问题所在。可能是配置错误。请帮助我

错误发生在 gunicorn 的 error.log 中

[2019-04-20 14:38:24 +0200] [14828] [CRITICAL] WORKER TIMEOUT (pid:21460)
[2019-04-20 12:38:24 +0000] [21460] [INFO] Worker exiting (pid: 21460)
[2019-04-20 14:38:24 +0200] [21500] [INFO] Booting worker with pid: 21500

这是我的 gunicorn 配置

import multiprocessing

timeout = 120
bind = 'unix:/tmp/gunicorn.sock'
workers = multiprocessing.cpu_count() * 2 + 1
reload = True
daemon = True
accesslog = './access.log'
errorlog = './error.log'

nginx 错误日志：

2019/04/21 14:26:28 [error] 7897#7897: *1 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 105.159.137.50, server: example.com, request: "GET /login/ HTTP/1.1", upstream: "http://unix:/tmp/gunicorn.sock/login/", host: $
$host: "www.example.com"

现在我遇到的不是 502 BAd Gateway，而是 504 Gateway Time-out

我的 django 应用程序错误日志中没有任何内容

答案1

我正在使用 django-instagram 从 instagram 个人资料中抓取图片，这就是问题所在。

我删除了 django-instagram 代码，但其运行良好。

但我想知道为什么从 Instagram 抓取数据会出现错误，是因为 nginx 配置吗？因为它在我的本地机器上运行良好
