http://abc.ccav.com/article/index/show/id/1 rewrite 到 http://www.ccav.com/article/index/show/uid/abc/id/1
http://abc.ccav.com/shop/index/index rewrite 到 http://www.ccav.com/shop/index/index/uid/abc

        proxy_set_header    Host   www.ccav.com;
        proxy_pass      http://127.0.0.1:80;
    }
    location / {
        set $uid default;
        if ( $http_host ~* "^(.*)\.u\.ccav\.com") {
            set $uid ;
        }
        rewrite ^/article/index/show/id/([0-9]+)/?$  /article/index/show/uid/$uid/id/ break;
        rewrite ^/article/index/index/?$  /article/index/index/uid/$uid break;
        rewrite ^/article/index/category/cid/([0-9]+)/?$  /article/index/category/uid/$uid/cid/ break;
        proxy_pass http://www.ccav.com;
    }
}

Answer 2

这是不重写，应该叫跳转，可以做301，当$host = 'abc.ccav.com' 时，^/(.*)$ http://www.ccav.com/$1 permanent; 思路就是这样的
