每年都要做很多老网站升级永易搜CMS的网站，主要的步骤就是：1、导入老程序的数据 2、原来的链接如果与新链接结构有差异的做一下301重定向。这是一个ngnix的服务器，所以要用到下边的规则：

location / {

    rewrite ^/software/(12|13|14|15|16|66|84|90|93).html$  http://www.weijingtai.org/software/yy/$1.html permanent;
    rewrite ^/software/(21|22|23|24|77|86|87|89).html$  http://www.weijingtai.org/kf/$1.html permanent;
    if (!-f $request_filename) {
        rewrite ^/(tag/.+|tag)/$ /tag.php?path=$1 last;
        rewrite ^/(tag/.+)/list_([0-9]+).html$ /tag.php?path=$1&p=$2 last;
        rewrite ^/s/$ /search.php last;
        rewrite ^/([a-zA-Z0-9/_]+)/$ /list.php?path=$1 last;
        rewrite ^/([a-zA-Z0-9/_]+)/list_([0-9]+).html$ /list.php?path=$1&p=$2 last;
        rewrite ^/([a-zA-Z0-9/_]+)/([a-z0-9-_]+).html$ /content.php?path=$1/$2.html last;
        rewrite ^/([a-zA-Z0-9-_]+).html$ /topic.php?path=$1 last;
        rewrite ^/(sitemap|rss).xml$ /api/$1.xml.php last;
    }
}
location ~ /.ht {
    deny all;
}
