【问题描述】：

欢迎 ***ers。我一直在努力用 django 应用程序用 uwsgi 设置 nginx ......某处必须有一个小错误，但我找不到它。这是我来自 pastebin 的文件，其中包含与我的问题直接相关的文件以及控制台日志。如果有人可以看看并帮助我，我会非常感激。

已解决 我将我的 nginx 文件链接到可用的站点，而不是因为我被认为启用了站点

【问题讨论】：

您如何尝试连接您的服务器？ nginx 错误日志是怎么说的？

“连接被拒绝”表示您尝试访问的端口未打开或前面可能有防火墙。我看到您的 nginx 正在侦听端口 8001。这也是您正在访问的端口吗？您是否还有另一台服务器（例如负载均衡器或缓存）从端口 80 代理到端口 8001？

首先我启动我的 nginx 然后我运行 uwsgi --ini artcolor_uwsgi.ini 下一步是运行 localhost:8001 （因为我的 nginx 正在侦听该端口）它应该将我重定向到我的artcolor.sock 我检查过，8001 上没有其他内容，我已将其更改为 9015 并重新启动了我的 nginx，但没有任何变化。

错误 400 是“错误请求”。您的网络浏览器发送了一个服务器不理解的请求。

我误解了 400 错误。它只是 ERR_CONNECTION_REFUSED

【参考方案1】：

解决方案：

我设法解决了问题。

原因是链接 nginx.conf 文件错误。

我不小心链接到sites-available，而不是我应该链接到sites-enabled

谢谢
