04 虚拟化技术基础原理
一、配置虚拟化网络
1、编辑配置文件
#关闭NetworkManager
[root@localhost ~]# service NetworkManager stop
[root@localhost ~]# chkconfig NetworkManager off
[root@localhost ~]# chkconfig --list NetworkManager
NetworkManager 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭
[root@localhost ~]# yum -y install bridge-utils
[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# cp ifcfg-eth0 ifcfg-br0
[root@localhost network-scripts]# vim ifcfg-br0
修改
DEVICE=eth0
为
DEVICE=br0
修改
TYPE=Ethernet
为
TYPE=Bridge
[root@localhost network-scripts]# vim ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
BRIDGE=br0
IPV6INIT=no
NAME="System eth0"
[root@localhost network-scripts]# service network restart
[root@localhost network-scripts]# ifconfig
br0 Link encap:Ethernet HWaddr 00:0C:29:F1:37:B9

[root@localhost network-scripts]# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.000c29f137b9 no eth0
#启用STP
[root@localhost network-scripts]# brctl stp br0 on
[root@localhost network-scripts]# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.000c29f137b9 yes eth0
二、命令方式
[root@localhost ~]# brctl show
bridge name bridge id STP enabled interfaces
[root@localhost ~]# brctl addbr br0
[root@localhost ~]# ifconfig eth0 0 up
[root@localhost ~]# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.000000000000 no
[root@localhost ~]# brctl addif br0 eth0
[root@localhost ~]# ifconfig br0 192.168.1.61/24 up
[root@localhost ~]# route add default gw 192.168.1.254
[root@localhost ~]# ifconfig
