跳转实现方法

1.别名：在配置文件里server段加入wolf.com即可实现

2.重写(rewrite)

第一种方法地址栏不变，第二种方法地址栏会跳转变化。

实验

1.配置文件加入wolf.com

[root@nginx conf]# vi nginx.conf
\
worker_processes  2;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  www.wolf.com wolf.com;  （这里加入wolf.com）
        location / {
            root   html/www;
            index  index.html index.htm;
        }
    }
        server {
        listen       80;
        server_name  bbs.wolf.com;
        location / {
            root   html/bbs;
            index  index.html index.htm;
        }
    }
        server {
        listen       80;
        server_name  blog.wolf.com;
        location / {
            root   html/blog;
            index  index.html index.htm;
        }
    }

客户端测试加入host表

2.重写301跳转

rewrite ^/(.*) http://www.wolf.com/$1 permanent;
[root@nginx conf]# cat nginx.conf         
worker_processes  2;
events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  wolf.com;
        location / {
            root   html/www;
            index  index.html index.htm;
            rewrite ^/(.*) http://www.wolf.com/$1 permanent;
        }
    }

        server {
        listen       80;
        server_name  www.wolf.com;
        location / {
            root   html/www;
            index  index.html index.htm;
        }
    }
        server {
        listen       80;
        server_name  bbs.wolf.com;
        location / {
            root   html/bbs;
            index  index.html index.htm;
        }
    }
        server {
        listen       80;
        server_name  blog.wolf.com;
        location / {
            root   html/blog;
            index  index.html index.htm;
        }
    }
##status
   server {
        listen       80;
        server_name  status.wolf.com;
        location / {
            stub_status on;
            access_log off;
        }
    }
}

再输入wolf.com，自动跳转到www.wolf.com

现在输入192.168.3.49，自动跳转到www.wolf.com

如果没有跳转段

    server {
        listen       80;
        server_name  wolf.com;
        location / {
            root   html/www;
            index  index.html index.htm;
            rewrite ^/(.*) http://www.wolf.com/$1 permanent;
        }
    }

使用ip访问默认为第一个server

3.防止恶意绑定域名

加入下面这段

server {
        listen       80;
        location / {
          deny all;
        }
    }

nginx: the configuration file /data/nginx1.8.1/conf/nginx.conf syntax is ok
nginx: configuration file /data/nginx1.8.1/conf/nginx.conf test is successful
[root@nginx conf]# ../sbin/nginx -s reload

测试curl或者ie访问都会报403错误

[root@nginx conf]# curl -I http://192.168.3.49/
HTTP/1.1 403 Forbidden
Server: nginx/1.8.1
Date: Wed, 16 Nov 2016 05:49:12 GMT
Content-Type: text/html
Content-Length: 168
Connection: keep-alive

hosts表里添加记录(恶意解析)

192.168.3.49 www.sex.com

在本地ie打开网页

会发现跳转到403界面
