LNMP - nginx配置静态文件过期时间

42121

                      网页中的的    也就缓存，过期时间。
1、编辑虚拟主机配置文件
[iyunv@bogon tmp]# vim /usr/local/nginx/conf/vhosts/test.confserver
{
    listen 80;
    server_name www.test.com www.aaa.com;
    if ($host != 'www.test.com')
    {
rewrite ^/(.*)$ http://www.test.com/$1 permanent;
    }
    index index.html index.htm index.php;
    root /data/www;
    access_log /tmp/access.log combined_realip;
    location ~ .*admin\.php$ {
  auth_basic "caimz auth";
auth_basic_user_file /usr/local/nginx/conf/.htpasswd;
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi1.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/www$fastcgi_script_name;
    }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
access_log off;
expires 15d;
    }
    location ~ \.(js|css)
    {
access_log off;
expires 2h;
    }
    location ~ (static|cache)
    {
access_log off;
    }
    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi1.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/www$fastcgi_script_name;
    }
}

2、检测配置文件的正确性
[iyunv@bogon tmp]# /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
3、重新加载配置文件
[iyunv@bogon tmp]# /usr/local/nginx/sbin/nginx -s reload

4、测试
使用chrome浏览器 按下F12，进入调试模式。

刷新知道之前设置的图片。cache-control 大小是1296000 也就是15天。15*60*60=1296000秒
cache-control也就是缓存时间


后者是命令行测试：
[iyunv@bogon tmp]# curl -x127.0.0.1:80 'http://www.test.com/static/js/forum.js?mWW' -I
