Nginx Gzip 压缩配置的例子

以前没关心过nginx的gzip功能，今天仔细看了一下，有点收获。

gzip的开关指令

gzip on # 用这个指令开启nginx的gzip功能，这个没开后面的都没用。

gzip_types 用这个指令告诉nginx对哪些类型的应答启动gzip。

注意: nginx默认只为text/html类型的应答启用了gzip, 所以像css,js之类的是不会被压缩的。加上后面这两个应该还是挺重要的，分别为text/css
application/javascript, 毕竟jQuery可能从90K压缩到30K。

其它还有几个gzip的指令，相对来说没那么重要，平时用用这两个就差不多了

环境：Debian 6

1、Vim打开Nginx配置文件

vim /usr/local/nginx/conf/nginx.conf

nginx 配置gzip段如下：

gzip on;
gzip_min_length 1k;
gzip_buffers 16 64k;
gzip_http_version 1.1;
gzip_comp_level 6;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;

用curl测试Gzip是否成功开启

curl -I -H "Accept-Encoding: gzip, deflate" "https://www.111cn.net /blog/"
