Centos7/Debian 配置双网卡

1. 添加一块虚拟网卡

   

2. ifconfig查看网卡device name，新建一个对应的配置文件vim /etc/sysconfig/network-script/ifcfg-name

   TYPE=Ethernet
   PROXY_METHOD=none
   BROWSER_ONLY=no
   BOOTPROTO=static
   DEFROUTE=yes
   IPV4_FAILURE_FATAL=no
   IPV6INIT=yes
   IPV6_AUTOCONF=yes
   IPV6_DEFROUTE=yes
   IPV6_FAILURE_FATAL=no
   IPV6_ADDR_GEN_MODE=stable-privacy
   NAME=ens34
   DEVICE=ens34
   ONBOOT=yes
   IPADDR=192.168.10.100
   NETMASK=255.255.255.0
   

   这里使用vmnet01 host-only，所以不需要设置网关
