示例1：

----------------------------------------------------------

server{

listen  80;

server_name    www.aaa.com;

location / {

root  /usr/share/nginx/aaa.com;

index  index.html index.htm;

}

}

# mkdir /usr/share/nginx/aaa.com

# echo aaa >> /usr/share/nginx/aaa.com/index.html

示例2：

----------------------------------------------------------

server{

listen 80;

server_name www.bbb.com;

location / {

root  /usr/share/nginx/bbb.com;

index  index.html index.htm;

}

}

# mkdir /usr/share/nginx/bbb.com

# echo bbb >> /usr/share/nginx/bbb.com/index.html

结果测试：

----------------------------------------------------------

#在另一台客户端机器上修改hosts文件

echo "192.168.88.101 www.aaa.com" >> /etc/hosts

echo "192.168.88.102 www.bbb.com" >> /etc/hosts

#打开浏览器输入地址：www.aaa.com看看结果页面上显示的是否是aaa

#打开浏览器输入地址：www.bbb.com看看结果页面上显示的是否是bbb
