使用nginx服務(wù)器的朋友可能都知道需要設(shè)置html靜態(tài)頁面緩存與頁面壓縮與過期時(shí)間的設(shè)置了，下面我來給各位同學(xué)介紹一下配置方法，包括對ico,gif,bmp,jpg,jpeg,swf,js,css,mp3文件進(jìn)行本地緩存.
可以通過nginx對服務(wù)器上的靜態(tài)資源進(jìn)行過期時(shí)間設(shè)置和對資源進(jìn)行壓縮傳輸來減少服務(wù)器的帶寬開銷。
以下是nginx對靜態(tài)資源過期時(shí)間的設(shè)置方法：

1

|
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(jìn)行本地緩存，不用每次訪問都重新從服務(wù)器獲取。
壓縮的配置如下：
|
1
2
3
4
|
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(jìn)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(tài)頁面,緩存過期時(shí)間
這里用虛擬機(jī)配置了下：
nginx 配置文件內(nèi)容：
主要是這一句：
|
1
|
proxy_cache_path /www/ levels=1:2 keys_zone=Z:10m inactive=1m max_size=30g; |
這一句定義一個(gè)區(qū)域，名字是 Z ，在內(nèi)存中的空間為10MB ，硬盤中的最大空間為 30G;
inactive=1m 是，1分鐘之后緩存失效 ，從新從源服務(wù)器請求
這里糾正一下，inactive=1m 如果緩存1分鐘沒人訪問，nginx 會刪除掉這些緩存

html 文件可以被緩存，后來就到很多地方去問
