Nginx Gunicorn Django -- upstream prematurely closed connection 错误

Question

我对 NGINX、GUNICORN、DJANGO 设置还很陌生。我在 nginx、gunicorn 之间使用 supervisor。在没有 NGINX 的情况下，设置可以很好地与 supervisor 和 gunicorn 配合使用，我可以通过我的服务器 IP 查看结果。但是当我使用 nginx 来处理请求时，出现错误 "upstream prematurely closed connection while reading response header from upstream"。请有人帮助我吗？

Supervisor command I am using:
sudo /path/to/gunicorn/gunicorn -k gevent --workers 4  --bind unix:/tmp/gunicorn.sock --chdir /path/to/application wsgi:application --timeout 120

下面是我目前正在使用的 nginx.conf，它按预期工作。但我不确定它是否符合要求。请调查一下。谢谢

请检查以下步骤：

首先要确保 gunicorn 正在创建 .sock 文件运行主管。您可以使用

来确保它

$sudo supervisorctl status <name-of-supervisor-task-for-it>
(check if service is RUNNING)

$ls /tmp    
(There should be a gunicorn.sock file existing there)

还要注意您分配给主管配置的用户。在这种情况下，您不需要在命令之前设置 root，只需将 root 用户的权限授予配置文件即可。像这样：

[program:myprogram]
command=/path/to/gunicorn/gunicorn -k gevent --workers 4 --bind unix:/tmp/gunicorn.sock --chdir /path/to/application wsgi:application --timeout 120
<other commands>
user=root

你的 nginx 配置应该是这样的：

upstream django {
server unix://tmp/gunicorn.sock;
}


server {
listen 80;
server_name <your_app_domain_here>;
location / {
include uwsgi_params;
proxy_pass http://django/;

}
