gzip压缩可以帮助我们节省带宽了,它可以帮助我们把10K的文件压缩到3k大小了,这个比例是非常的高的了,下面来看Nginx 开启gzip压缩(图片,文件,css)的配置.
1、Vim打开Nginx配置文件
vim /usr/local/nginx/conf/nginx.conf
2、找到如下一段,进行修改.
- gzip on;
- gzip_min_length 1k;
- gzip_buffers 4 16k;
- #gzip_http_version 1.0;
- gzip_comp_level 2;
- gzip_types text/plain application/x-<a href="/js_a/js.html" target="_blank">javascript</a> text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
- gzip_vary off;
- gzip_disable "MSIE [1-6]\.";
3、解释一下
第1行:开启Gzip
第2行:不压缩临界值,大于1K的才压缩,一般不用改
第3行:buffer,就是,嗯,算了不解释了,不用改
第4行:用了反向代理的话,末端通信是HTTP/1.0,有需求的应该也不用看我这科普文了;有这句的话注释了就行了,默认是HTTP/1.1
第5行:压缩级别,1-10,数字越大压缩的越好,时间也越长,看心情随便改吧
第6行:进行压缩的文件类型,缺啥补啥就行了,JavaScript有两种写法,最好都写上吧,总有人抱怨js文件没有压缩,其实多写一种格式就行了
第7行:跟Squid等缓存服务有关,on的话会在Header里增加"Vary: Accept-Encoding",我不需要这玩意,自己对照情况看着办吧
第8行:IE6对Gzip不怎么友好,不给它Gzip了
4、:wq保存退出,重新加载Nginx
/usr/local/nginx/sbin/nginx -s reload
5、用curl测试Gzip是否成功开启.
- curl -I -H "Accept-Encoding: gzip, deflate" "http://www.111cn.net/"
- HTTP/1.1 200 OK
- Server: nginx/1.0.15
- Date: Sun, 26 Aug 2012 18:13:09 GMT

最后来个不到1K的文件,由于我的阈值是1K,所以没压缩.
