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

[root@daixuan nginx_log]# cd /usr/local/nginx/conf/vhosts/

[root@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;

}

[root@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

[root@daixuan vhosts]# /etc/init.d/nginx reload

重新载入 Nginx：                                        [确定]

[root@daixuan vhosts]# service nginx restart

停止 Nginx：                                           [确定]

正在启动 Nginx：                                        [确定]

二、测试

[root@daixuan vhosts]# curl -x127.0.0.1:80 'http://www.test.com/static/p_w_picpath/common/security.png' -I
