VirtualBox網絡的Host-Only配置

創建host-only虛擬網卡

VBox管理器頁面-管理-主機網絡管理器，如果已經存在默認的虛擬網卡則下一步，如果不存在則創建一個虛擬網卡，不啟用DHCP服務器，這里ip地址為192.168.137.1，實際我本地設置為192.168.102.1，掩碼設置為255.255.255.0。

 

設置虛擬機master和slave1, slave2為Host-Only模式

 

配置各台虛擬機的網絡

vi /etc/sysconfig/network-scripts/ifcfg-eth0

 

master 

DEVICE=eth0
HWADDR=08:00:27:5D:52:BC
TYPE=Ethernet
UUID=d2cdd853-f19c-4dd7-bfdf-ea6b8a954b54
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.102.3
NETMASK=255.255.255.0
GATEWAY=192.168.102.1
DNS1=192.168.102.1

slave1

DEVICE=eth0
HWADDR=08:00:27:DC:F2:46
TYPE=Ethernet
UUID=14155cf0-7177-4ed7-94cd-5325f9f94c8a
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.102.4
NETMASK=255.255.255.0
GATEWAY=192.168.102.1
DNS1=192.168.102.1

slave2

DEVICE=eth0
HWADDR=08:00:27:DC:F2:46
TYPE=Ethernet
UUID=14155cf0-7177-4ed7-94cd-5325f9f94c8a
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.102.5
NETMASK=255.255.255.0
GATEWAY=192.168.102.1
DNS1=192.168.102.1

重啟各台虛擬機網絡服務

service network restart

關閉各台虛擬機的防火牆

1. 永久性生效

開啟：chkconfig iptables on

關閉：chkconfig iptables off

2. 即時生效，重啟后失效

開啟：service iptables start

關閉：service iptables stop

 

Fedora 18以上用一個名叫firewalld的玩意，所以需要：

systemctl stop firewalld.service有必要的話就

systemctl disable firewalld.service
