Nginx設置靜態頁面壓縮和緩存過期時間的方法

使用nginx服務器的朋友可能都知道需要設置html靜態頁面緩存與頁面壓縮與過期時間的設置了，下面我來給各位同學介紹一下配置方法，包括對ico,gif,bmp,jpg,jpeg,swf,js,css,mp3文件進行本地緩存.

可以通過nginx對服務器上的靜態資源進行過期時間設置和對資源進行壓縮傳輸來減少服務器的帶寬開銷。

以下是nginx對靜態資源過期時間的設置方法：

location ~* .(ico|gif|bmp|jpg|jpeg|png|swf|js|css|mp3) {
  root  /var/www/opkeep;
  expires 30d;
}

上面的配置可以對ico,gif,bmp,jpg,jpeg,swf,js,css,mp3文件進行本地緩存，不用每次訪問都重新從服務器獲取。

壓縮的配置如下：

gzip on;
gzip_min_length 1000;
gzip_buffers   4 8k;
gzip_types    text/plain application/x-javascript text/css;

對文本、js和css文件進行壓縮，一般情況下，壓縮后的大小是原始大小的25%，甚至更小。

緩存動態頁面,緩存過期時間

這里用虛擬機配置了下：

nginx 配置文件內容：

主要是這一句：

proxy_cache_path /www/ levels=1:2 keys_zone=Z:10m inactive=1m max_size=30g;

這一句定義一個區域，名字是 Z ，在內存中的空間為10MB ，硬盤中的最大空間為 30G;

 inactive=1m   是，1分鍾之后緩存失效 ，從新從源服務器請求
這里糾正一下，inactive=1m  如果緩存1分鍾沒人訪問，nginx 會刪除掉這些緩存
