Nginx 記憶體控制/過期標頭將不起作用

我到處尋找這個問題的有效答案，但似乎沒有一個答案有效。我也很抱歉這篇超長的文章，但我只需要在這方面尋求幫助。我試圖盡可能詳細。

我在從原始碼建構的 CentOS 7 上安裝了 ngx_pagespeed 的 nginx 網路伺服器，在我的一生中，我無法獲取cache-control或expire標頭工作。我在這裡、StackOverflow、nginx wiki 上搜尋並嘗試了所有建議的“解決方案”，並且已經看到了大約 50 個不同的頁面，它們以不同的方式讓人們“工作”。

現在我知道 ngx_pagespeed 有自己的記憶體，但我的網站似乎並沒有從中受益。所以我正在嘗試為媒體（jpg、gif 等）設置我自己的標題cache-control和標題。expire但是，在過去的兩天裡，我得到的只是：

curl -I 的輸出

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

我對此感到非常沮喪。無論我嘗試什麼，除了我什麼都得不到

cache-control: max-age=0, no-cache從捲曲。

以下是我的配置文件。我的站點的配置在，/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;
   }

我認為其餘的nginx.conf無關緊要。無論如何，預設情況下它都被註釋掉了。這個文件可能有各種各樣的錯誤。我嘗試在這裡添加一些我發現為其他人“修復”它的東西。

這些配置工作並通過nginx -t，但記憶體不起作用。我留下了所有註釋掉的程式碼，所以你可以看到我做了什麼/嘗試了什麼。在這裡的任何幫助將不勝感激。如果我錯過了任何需要的細節，請告訴我。謝謝！

在Tero Kilkanen的一些指導下，我能夠從託管媒體的 S3 儲存桶中設置cache-control和expires標頭，而不是從我的 nginx 網路伺服器。

謝謝！
