使用VMware搭建3台一模一样的Linux虚拟机(3)

(2) dhcp方式自动设置网络

[root@name01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=dhcp

HWADDR=00:0c:29:ae:6b:a7

ONBOOT=yes

TYPE=Ethernet

[root@name01 ~]#

重启network服务

[root@name01 ~]# service network restart

Shutting down interface eth0: Device state: 3 (disconnected)

[ OK ]

Shutting down loopback interface: [ OK ]

Bringing up loopback interface: [ OK ]

Bringing up interface eth0: Active connection state: activating

Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/3

state: activated

Connection activated

[ OK ]

[root@name01 ~]#



(3) 验证网络，使用wget下载lib包，如下所示：

[root@name01 ~]# wget
