Nginx开启Gzip压缩大幅提高页面加载速度

[root@12 conf]# vi nginx.conf

        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;
        #gzip_http_version 1.0;
        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 text/css application/xml;
         gzip_types       text/plain application/x-javascript text/css application/xmli text/javascript application/x-httpd-php image/jpeg image/gif image/png;

        gzip_vary off;
        gzip_disable "MSIZE [1-6]\.";#IE6对Gzip不怎么友好，不给它Gzip
