提供静态内容 NGINX

Question

我是 NGINX 的新手。我还不太了解它，但我正在尝试。我很好奇使用 NGINX 从我的页面提供静态内容的最佳方式是什么。我想提供静态内容的主要原因是我想减少我的应用程序服务器的负载，并提高页面加载速度。

遇到了

几篇好文章帮助我把这些放在一起 post : here, here, here, and here.

但一切还是有点清晰。

配置

文件路径：etc/nginx/default

server {

    listen 80 default_server;
    server_name default;
    root /home/forge/site/public;

    location / {
        proxy_pass http://43.35.49.160/;
        try_files $uri $uri/ /index.php?$query_string;
    }

    # Media: images, icons, video, audio, HTC
    location ~* \.(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ {
        expires 1M;
        access_log off;
        add_header Cache-Control "public";
    }

    # CSS and Javascript
    location ~* \.(?:css|js)$ {
        expires 1y;
        access_log off;
        add_header Cache-Control "public";
    }
}

Test/Result

保存我的文件后，我运行 service nginx reload.

接下来，我尝试了运行 : curl -X GET -I http://45.33.69.160/index.php

我得到了：

然后，我尝试了运行curl -X GET -I http://45.33.69.160/css/custom.css

我得到了：

为什么我看到 Cache-Control: no-cache 而我刚刚设置了缓存？

我现在一切都不清楚。

问题

谁能说清楚如何做:

正确配置
测试该配置是否有效
查看缓存和不缓存的区别
对其进行基准测试并在页面或 CLI 上打印出该报告

?

Answer 1

`Cache-Control: no-cache`

如this answer about no-cache, which links to the spec, the Cache-Control: no-cache should tell the user agent and in-between caches which caching style to use (namely to revalidate each time with the server). This applies if you use nginx exclusively. If you use it as a pass-through, you need to set proxy_ignore_headers所说，喜欢

proxy_ignore_headers Cache-Control;

配置

除此之外：在 NGINX reference about content caching 中，它表示要放置行

    proxy_cache_path /data/nginx/cache keys_zone=one:10m;

在http部分，后面是

        proxy_cache one;

在server部分。

测试

In this SF question，它表示通过配置文件

添加 X-Cache-Status header 来测试缓存行为

add_header X-Cache-Status $upstream_cache_status;

Its answer 表示

You can view headers with

the Firefox addon firebug

the Chrome debugging console

cURL (curl -I )
