在nginx服务器rhel-400上部署django应用程序，请求头或cookie太大

Question

我目前正在尝试使用Nginx在REHL 7.4服务器上部署Django应用程序。我遵循了以下教程：

https://simpleisbetterthancomplex.com/tutorial/2017/05/23/how-to-deploy-a-django-application-on-rhel.html

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04

virtualenv和nginx服务器似乎都很好。然而，我正在与两个错误作斗争：

• 要么是因为worker_connections参数值(下面是日志)，我得到了一个500错误：

  13494#0:*1021 1024个worker_connections在连接到上游时不够，客户端：192.168.1.33，服务器：192.168.1.33，请求："GET/Syc/login HTTP/1.0"，上游："http://192.168.1.33:80/Syc/login"，主机："192.168.1.33">

• 要么我将worker_connections值增加到>4096，然后我得到一个400错误，就像这个线程中的400错误请求-请求标头或cookie太大

下面是我的nginx.conf和app.conf，如果有配置错误，请告诉我，并提前感谢您的帮助。

nginx.conf:

include /usr/share/nginx/modules/*.conf;

# set open fd limit to 30000

location = /40x.html {

error_page 500 502 503 504 /50x.html;

app.conf

upstream app_server {

proxy_redirect off;
proxy_pass http://192.168.1.33;
}
}

Answer 1

尝试删除/注释行：

proxy_set_header Host $http_host;

或增加CCD_ 1。
