Nginx 缓存控制 / 过期标头将不起作用

Nginx 缓存控制 / 过期标头将不起作用

我到处寻找这个问题的有效答案，但似乎没有一个答案有效。我很抱歉发了这么长的帖子，但我只是想就此寻求帮助。我尽量写得尽可能详细。

我在 CentOS 7 上安装了 ngx_pagespeed 的 nginx 网络服务器，我从源代码构建，但无论如何，我都无法让cache-control或expire标头工作。我搜索并尝试了这里、StackOverflow、nginx wiki 上建议的每一个“解决方案”，并且看到了大约 50 个不同的页面，其中介绍了人们让他们的“工作”的不同方法。

现在我知道 ngx_pagespeed 有自己的缓存，但我的网站似乎没有从中受益。所以我尝试设置自己的媒体 (jpg、gif 等)cache-control标题expire。但是，在过去的两天里，我得到的只是：

curl -I 的输出

HTTP/2 200
server: nginx
content-type: text/html; charset=UTF-8
vary: Accept-Encoding
x-frame-options: SAMEORIGIN
x-xss-protection: 1; mode=block
strict-transport-security: max-age=31536000
x-content-type-options: nosniff
date: Tue, 26 Jun 2018 02:02:46 GMT
x-page-speed: Powered By ngx_pagespeed
cache-control: max-age=0, no-cache

我对此感到非常沮丧。无论我怎么努力，我都无法得到任何东西，除了

cache-control: max-age=0, no-cache从卷曲。

以下是我的配置文件。我的站点的配置在，/etc/nginx/sites-available/conf而 nginx 的配置文件在/etc/nginx/nginx.conf。

nginx.conf：

user  centos;
worker_processes  1;


#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    include /etc/nginx/sites-enabled/*;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local]                 
    "$request" '
    #'$status $body_bytes_sent "$http_referer" '
    #'"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

     server {
        listen       80;
        server_name  localhost;
    }

我认为其余部分nginx.conf无关紧要。默认情况下，它们都被注释掉了。此文件可能有各种错误。我尝试在这里添加我发现的可以为其他人“修复”的问题的内容。

这些配置有效并且通过了，nginx -t但缓存就是不起作用。我保留了所有注释掉的代码，以便您可以看到我所做/尝试过的事情。任何帮助都将不胜感激。如果我遗漏了任何需要的详细信息，请告诉我。谢谢！

答案1

在一些指导下泰罗·基尔卡宁，我能够从托管媒体的 S3 存储桶中设置cache-control和标头，而不是从我的 nginx 网络服务器中设置。expires

谢谢你！
