Question

我在nginx服务器上使用gunicorn运行Django 2.0。我的所有页面都没有立即反映出这些变化。如何停止缓存

以下是我的文件：

nginx.conf

server {
    listen 80;
    server_name sample.com;

    location = /favicon.ico { access_log off; log_not_found off; }

    location /static/ {
        root /home/testapp/testapp_project/test_artciles;
    }
    location /media/ {
        root /home/testapp/testapp_project/test_artciles;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/testapp/testapp_project/test_artciles.sock;
    }

}

我确信它与服务器有关，因为当我在传输到服务器之前在我自己的笔记本电脑上运行本地代码时，事情就会立即反映出来。

Answer 1

在服务器上更改代码后，您应该重新启动 gunicorn 以更新工作版本：

sudo systemctl restart gunicorn

或者您可以使用 --reload 模式，一旦代码更改，就会更新 gunicorn：

gunicorn --workers=2 test:app --reload

您可以在文档 https://docs.gunicorn.org/en/stable/settings.html#reload

上阅读它

Answer 2

如果您正在谈论服务器缓存，那么以下是为我工作的步骤：

我的实施细节是

gunicorn         19.9.0,
Django           1.11.16,
nginx version: nginx/1.10.3,
Os (Ubuntu)

Gunicorn尚未缓存，除非您已安装并启用https://pypi.org/project/gunicorn_cache/
禁用Django缓存，

from django.views.decorators.cache import never_cache


@never_cache
def generating the cached data/results():

禁用ngnix缓存

location todisablecaching {
  proxy_no_cache 1;
  proxy_cache_bypass 1;
  ...
}

https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_no_cache，

https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_cache_bypass

我希望它也对您有用。
