域名泛解析后nginx拒绝未绑定域名

第一种：

返回HTTP 状态码

1. server {

2. listen 80 default;

3. server_name _;

4. return 403;

5. }

default表示默认主机


403为Http状态码，可根据需要修改


这样可以屏蔽所有域名（除了你自己绑定的）和IP的访问。


我们也可以吧return 403;改成重定向，把非法访问重定向到其他地址

第二种：

1. server {

2. listen 80 default;

3. server_name _;

4. rewrite ^(.*) http://www.baidu.com permanent;

5. }

改成重定向，把非法访问重定向到其他地址

例子：如下为Nginx.conf的配置
