VirtualBox網絡配置

1.配置host-only：主機通訊

修改 /etc/sysconfig/network-script/ifcfg-eth0 注意HWADDR和VirtualBox網絡配置裏host-only模式mac一致

HWADDR=08:00:27:FE:24:46
TYPE=Ethernet
BOOTPROTO=static
NETMASK=255.255.255.0
IPADDR=192.168.56.100
GATEWAY=192.168.56.254
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eth0
UUID=642a94f2-30e8-4db7-91ec-3af99a8f2a5f
ONBOOT=yes

2.配置網絡地址轉換(NAT)：上外網

修改 /etc/sysconfig/network-script/ifcfg-eth1 注意HWADDR和VirtualBox網絡配置裏NAT模式mac一致

HWADDR=08:00:27:81:A6:34
TYPE=Ethernet
BOOTPROTO=dhcp
NAME=eth1
ONBOOT=yes

3.確認配置
