Nginx 服务重写重定向防盗链

1.转向同一目录：
server {
          listen       80;        #监听80端口
            server_name www.kuitao8.com abc.kuitao8.com;
        index index.html index.php;
        root /opt/nginx/html;
        if ($http_host ~ "^www\.kuitao8\.com$"){
          rewrite /(.*) http://abc.kuitao8.com last;
        }
   }

2.302重定向：
server {
     listen 80;
     server_name www.kuitao8.com    abc.kuitao8.com kuitao8.com;
     if ($http_host != "www.kuitao8.com"){
         rewrite ^/(.*) http://www.kuitao8.com/$1 permanent;
     }

3.301重定向:
       server {
     listen 80;
     server_name www.kuitao8.com    abc.kuitao8.com kuitao8.com;
     if ($http_host != "www.kuitao8.com"){
         rewrite ^/(.*) http://www.kuitao8.com/$1 redirect;
     }

4.防盗链（返回412错误）
1）服务器配置文件设置：
       location ~* ^.+\.(jpg|jpeg|gif|png|swf|rar|zip)$ {
         valid_referers none blocked www.kuitao8.com ;
         if ($invalid_referer){
         #   rewrite ^/ http://www.kuitao8.com/a.gif;
             return 412;
             break;
         }
        access_log off;     #关闭日志
         root /opt/nginx/html;    # root
         expires 3d;         #3天自动清除缓存
         break;                       #中止rewrite不继续匹配
     }
服务器上放置一张a.png的图片
2）客户访问中插入一个图片超链接：
<html>
<head>
<title>Welcome to nginx!</title>
</head>
<body bgcolor="white" text="black">
<center><h1>Welcome to nginx!</h1>
        <h1> This is the desktop233</h1>
<a href=http://img.kuitao8.com/uploads/2013/1129/20131129053914426.png" >showpng</a> #链接到服务器上的图片
</center>
</body>
</html>
