Nginx如何配置静态文件过期时间
与Apache使用expires_module (shared)模块配置静态缓存不同，Nginx使用修改对应虚拟主机配置文件即可。
一、编辑虚拟主机配置文件
[iyunv@daixuan nginx_log]# cd /usr/local/nginx/conf/vhosts/
[iyunv@daixuan vhosts]# vim test.conf //jpg15天过期，js，css2小时过期

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ {
        access_log off;
        expires 15d;
    }
    location ~ .*\.(js|css) {
        access_log off;
        expires 2h;
    }

[iyunv@daixuan vhosts]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[iyunv@daixuan vhosts]# /etc/init.d/nginx reload
重新载入 Nginx：                                        [确定]
[iyunv@daixuan vhosts]# service nginx restart
停止 Nginx：                                           [确定]
正在启动 Nginx：                                        [确定]

二、测试
[iyunv@daixuan vhosts]# curl -x127.0.0.1:80 'http://www.test.com/static/image/common/security.png' -I
