Azure的每个VM都有多种IP地址，包括DIP、VIP和PIP。具体如下：
DIP地址是在VM里能够看到的IP地址，即私网地址；PIP地址是这个VM关联的公网IP地址，即公网地址；VIP地址是负载均衡的地址。
目前Azure的VM已经支持每个网卡关联多个ipconfig，即可以支持VM的每个网卡关联多个私网和公网地址：DIP和PIP。
如下图：
具体配置如下：
1. VM种NIC的ipconfig
2. 添加ipconfig
点击添加后：
按相同的方法再添加第三个ipconfig，配置完后的配置结果：
3. VM内的配置（CentOS7）
登录到VM中，做如下修改：
[root@hwvntp01 init.d]# cd /etc/sysconfig/network-scripts/ [root@hwvntp01 network-scripts]# vim ifcfg-eth0:0 DEVICE=eth0:0 ONBOOT=yes BOOTPROTO=static IPADDR=10.3.1.6 NETMASK=255.255.255.0 [root@hwvntp01 network-scripts]# vim ifcfg-eth0:1 DEVICE=eth0:1 ONBOOT=yes BOOTPROTO=static IPADDR=10.3.1.7 NETMASK=255.255.255.0
然后重启Network的服务：
[root@hwvntp01 network-scripts]# cd /etc/init.d
[root@hwvntp01 init.d]# ./network restart
4. 检验

5. 通过服务检验
在VM中安装httpd：
yum install -y httpd systemctl start httpd systemctl status httpd ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled; vendor preset: disabled) Active: active (running) since Fri 2017-04-14 08:49:38 UTC; 6s ago Docs: man:httpd(8) man:apachectl(8) Main PID: 14147 (httpd)
从外部检测：
三个地址都可以访问。
