【问题描述】:
我正在尝试在 Ubuntu DigitalOcean 液滴上的 Python 3.5.3 上运行一个相对简单的 Django 服务器。我正在使用带有 nginx 的 Gunicorn 服务器。
settings.py 中DEBUG=True 时服务器运行良好。但是当我将它设置为 False 时,我在尝试访问该页面时收到 400 错误。我尝试设置ALLOWED_HOSTS = ['*'],但仍然出现同样的错误。
我查看了很多关于 SO 的论坛和许多问题,但没有一个解决方案有效。

Nginx 日志显示错误:
request: "GET / HTTP/1.1", upstream: "http://unix:/home/thomas/KivaWebsite/KivaWebsite.sock:/", host: "104.131.153.181"
2016/09/12 12:06:47 [crit] 22081#22081: *96 connect() to unix:/home/thomas/KivaWebsite/KivaWebsite.sock failed (2: No such file or directory)
但是,我已经检查过,该文件确实存在。这是我的 nginx 配置文件:
server {
listen 80;
server_name 104.131.153.181;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /home/thomas/KivaWebsite;
}
location / {
include proxy_params;
proxy_set_header Host $host;
proxy_pass http://unix:/home/thomas/KivaWebsite/KivaWebsite.sock;
}
}
有什么问题吗?
【问题讨论】:
-
您是否尝试查看服务器日志? 400 表示可能是格式错误的请求或其他客户端错误
-
我的(随机)猜测是 nginx 从未期望 SSL 从 wsgi_pass 返回。我从不使用 gunicorn,但最后一行 (
[DEBUG] GET /) 表明请求已到达 gunicorn。您还拥有 /var/log/nginx 中的 nginx 日志 -
您是否使用绝对路径为 nginx 配置起了别名? (即:
/etc/nginx/sites-enabled)如果别名是使用相对路径完成的(出于某种原因),则它不起作用。尝试在proxy_pass行之前的location /上设置此设置,而不是当前行:proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto $scheme; proxy_redirect off; include uwsgi_params; -
@Av4t4r 非常感谢!我的配置文件中的更改有效!让它成为一个答案,我会接受它。
-
@TheRuler 完成 :)。但是,出于安全原因,我强烈建议您将
ALLOWED_HOSTS更改为仅接受来自 localhost 和当前内部网络的连接(对于 DigitalOcean,我认为它应该只设置为 localhost)
