========my nginx.conf===========  
server {

```
           listen 10.1.1.1:80;
           server_name www.test1.com;
           root /opt/test1;
   }

```

server {

```
           listen 80;
           server_name www.test2.com;
           root /opt/test2;
   }

```

========my nginx.conf===========  
I found that server [www.test2.com](http://www.test2.com) not listen on 10.1.1.1 ,but only  
listen on 127.0.0.1,why ?

Probably, you mistook: in this case nginx listen on \*:80 only.

If you want to bind() to an address, then you should set  
listen 10.1.1.1:80 default bind;

Yes,I saw that nginx listen on 0.0.0.0:80  
but when I use :  
curl -v -H “Host: [www.test2.com](http://www.test2.com)” [http://10.1.1.1/index.html](http://10.1.1.1/index.html)  
I get the result of [www.test1.com/index.html](http://www.test1.com/index.html),

and use  
curl -v -H “Host: [www.test2.com](http://www.test2.com)” [http://127.0.0.1/index.html](http://127.0.0.1/index.html)  
then get the result of [test2.com&nbsp;-&nbsp;test2 Resources and Information.](http://www.test2.com/index.html)

In this case ,does “listen \*:80” means this virtual\_server only bind  
to the ip address not used by any other virtual\_server?

Although nginx listen on \*:80, nevertheless it tests an address where  
a request was sent to, as if nginx was bind() to the address. It  
emulates  
usual socket bind() behaviour.
