剛剛給博客加了一個500px相冊插件,lightbox引入了很多js文件和css文件,頁面一下子看起來非常臃腫,所以還是把Gzip打開了。
環境:Debian 6
1、Vim打開Nginx配置文件
vim /usr/local/nginx/conf/nginx.conf
2、找到如下一段,進行修改
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、解釋一下
第1行:開啟Gzip
第2行:不壓縮臨界值,大于1K的才壓縮,一般不用改
第3行:buffer,就是,嗯,算了不解釋了,不用改
第4行:用了反向代理的話,末端通信是HTTP/1.0,有需求的應該也不用看我這科普文了;有這句的話注釋了就行了,默認是HTTP/1.1
第5行:壓縮級別,1-10,數字越大壓縮的越好,時間也越長,看心情隨便改吧
第6行:進行壓縮的文件類型,缺啥補啥就行了,JavaScript有兩種寫法,最好都寫上吧,總有人抱怨js文件沒有壓縮,其實多寫一種格式就行了
第7行:跟Squid等緩存服務有關,on的話會在Header里增加"Vary: Accept-Encoding",我不需要這玩意,自己對照情況看著辦吧
第8行:IE6對Gzip不怎么友好,不給它Gzip了
4、:wq保存退出,重新加載Nginx
/usr/local/nginx/sbin/nginx -s reload
5、用curl測試Gzip是否成功開啟
curl -I -H "Accept-Encoding: gzip, deflate" "http://www.slyar.com/blog/"HTTP/1.1 200 OKServer: nginx/1.0.15Date: Sun, 26 Aug 2012 18:13:09 GMTContent-Type: text/html; charset=UTF-8Connection: keep-aliveX-Powered-By: PHP/5.2.17p1X-Pingback: http://www.slyar.com/blog/xmlrpc.phpContent-Encoding: gzip
頁面成功壓縮

css文件成功壓縮
