如何开启Nginx的gzip压缩功能?

开启Nginx的gzip压缩功能详解

默认情况下,Nginx的gzip压缩是关闭的, gzip压缩功能就是可以让你节省不少带宽,但是会增加服务器CPU的开销哦,Nginx默认只对text/html进行压缩 ,如果要对html之外的内容进行压缩传输,我们需要手动来调。开启gzip的指令如下:

gzip on;
gzip_http_version 1.0;
gzip_disable "MSIE [1-6].";
gzip_types text/plain application/x-javascript text/css text/javascript;

关于gzip_types,如果你想让图片也开启gzip压缩,那么用以下这段吧:

gzip_types text/plain application/x-javascript text/css text/javascript application/x-httpd-php image/jpeg image/gif image/png;

网站开启gzip压缩,不仅能够节省带宽,也能够快速响应用户的访问,在nginx中,开启gzip压缩的方法为:

gzip on; (启用 gzip 压缩功能)

gzip_proxied any;(nginx 做前端代理时启用该选项,表示无论后端服务器的headers头返回什么信息,都无条件启用压缩)

gzip_min_length 1024;(最小压缩的页面,如果页面过于小,可能会越压越大,这里规定大于1K的页面才启用压缩)

gzip_buffers 4 8k;(设置系统获取几个单位的缓存用于存储gzip的压缩结果数据流)

gzip_comp_level 3; (压缩级别,1压缩比最小处理速度最快,9压缩比最大但处理最慢,同时也最消耗CPU,一般设置为3就可以了)

gzip_types text/plain text/css application/x-javascript application/javascript application/xml;(什么类型的页面或文档启用压缩)
