Azure上每个VM多个IP地址

cdchenli

　　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：



[iyunv@hwvntp01 init.d]# cd /etc/sysconfig/network-scripts/
[iyunv@hwvntp01 network-scripts]# vim ifcfg-eth0:0
DEVICE=eth0:0
ONBOOT=yes
BOOTPROTO=static
IPADDR=10.3.1.6
NETMASK=255.255.255.0
[iyunv@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：



[iyunv@hwvntp01 network-scripts]# cd /etc/init.d
[iyunv@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。
