在实际运维中,为了提高web页面的访问加载速度,一般会把静态资源(比如js、css、img等)在服务器进行压缩再传输到客户浏览器,主要配置步骤如下:

环境:Centos

1、Vim打开Nginx配置文件

vim /etc/nginx/nginx.conf

2、找到如下一段,进行修改

gzip on; // 开启Gzip
gzip_min_length 1k; // 不压缩临界值,大于1K的才压缩,一般不用改
gzip_buffers 4 16k; // buffer,就是,嗯,算了不解释了,不用改
#gzip_http_version 1.0; // 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
gzip_comp_level 2; // 压缩级别,1-10,数字越大压缩的越好,时间也越长!
gzip_types text/plain application/x-javascript application/javascript text/javascript text/css application/xml application/x-httpd-php image/jpeg image/gif image/png; // 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
gzip_vary off; // 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
gzip_disable "MSIE [1-6]\."; // IE6对Gzip不怎么友好,不给它Gzip了

3、:wq保存退出,重新加载Nginx

nginx -s reload

4、用curl测试Gzip是否成功开启

curl -I -H "Accept-Encoding: gzip, deflate" "http://www.slyar.com/blog/"
