網(wǎng)站上線了,發(fā)現(xiàn)慢點(diǎn)夠可以,特別是圖片及靜態(tài)資源加載,是什么原因?
nodejs的弊端,不太適合處理靜態(tài)資源,配合nginx的反向代理,速度能提升不少。
1、gzip默認(rèn)沒有開啟
2、node應(yīng)用的靜態(tài)資源,交給nginx處理,用nginx轉(zhuǎn)發(fā),實(shí)現(xiàn)動(dòng)靜態(tài)分離
3、開啟靜態(tài)資源緩存
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript image/svg+xml;
gzip on;
gzip_disable "msie6";
1、可以考慮用個(gè)二級(jí)域名,如http://static.jsout.com
2、如果不用二級(jí)域名,也可以通過nginx配置目錄達(dá)到目的
