刚刚给博客加了一个500px相册插件,lightbox引入了很多js文件和css文件,页面一下子看起来非常臃肿,所以还是把Gzip打开了。

环境:Debian 6

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-javascript 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.slyar.com/blog/"

HTTP/1.1 200 OK
Server: nginx/1.0.15
Date: Sun, 26 Aug 2012 18:13:09 GMT

Accept-Ranges: bytes

最后来个不到1K的文件,由于我的阈值是1K,所以没压缩
