A domain name corresponds to an ip address, and an ip address can be bound by multiple domain names.
Local tests can modify hosts files.
Modify window s hosts file: (C:\Windows\System32\drivers\etc)
You can configure the mapping relationship between domain name and ip. If the corresponding relationship between domain name and IP is configured in the hosts file, you do not need to go to the dns server.
# Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10

There is also a useful tool, SwitchHosts!.exe

After binding the relationship between ip and domain name
Next we'll finish on the virtual host
cd /usr/local/nginx
Found -rw-r--r--. 1 root 2656 July 28 01:39 nginx.conf
Add server configures the same port, but server_name is the bound domain name
server { listen 80; server_name wwww.camel.com; #charset koi8-r; #access_log logs/host.access.log main; location / { root html-test1; index index.html index.htm; } } server { listen 80; server_name wwww.camel1.com; #charset koi8-r; #access_log logs/host.access.log main; location / { root html-test; index index.html index.htm; } }
Step 1 cd/usr/local/nginx/copy html
[root@Nigux nginx]# cp -r html html-test [root@Nigux nginx]# cp -r html html-test1
Differentiate between two different interfaces

After modifying the page, after shift+zz save exits, restart the service
[root@Nigux nginx]# sbin/nginx -s reload
