VMware 6 上安装完Linux后,无法通过DHCP动态获得地址
VMware 6 上安装完Linux后,无法通过DHCP动态获得地址,网络也就无法使用;但如果使用静态地址,网络又可以使用了。
Vmware使用的是“桥接”的方式
使用动态地址时,使用Ifconfig eth0查看网络接口如下:
[root@localhost root]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0C:29:15:E6:CC
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:370 errors:0 dropped:0 overruns:0 frame:0
TX packets:401 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:278462 (271.9 Kb) TX bytes:58240 (56.8 Kb)
Interrupt:10 Base address:0x2024
没有IP地址
Ping 外部地址:
[root@localhost root]# ping 61.139.2.69
connect: Network is unreachable
将Eth0 down掉后再up起来,然后用dhclient eth0获取地址,仍然无效:
[root@localhost root]# ifconfig eth0 down
[root@localhost root]# ifconfig eth0 up
[root@localhost root]# dhclient eth0

还是获得不了地址!!郁闷
--------------------------
将网卡绑上静态IP
[root@localhost root]# ifconfig eth0

静态IP下网络就OK了!
请高手指点一下,如何搞定DHCP啊?为什么获得不到地址呢?
------解决方案--------------------Bridged 需要手动指定 IP
NAT 可以用 DHCP,也可以用 手动指定
------解决方案--------------------使用自动获取IP必须装上vmtools啊,你先装上他再说啊,我的就是 啊!!!
------解决方案--------------------NAT方式就可以
------解决方案-------------------- 看看vmware 的网卡参数,有关dhcp的设置好。一般,vmware 提供8个虚拟网卡,用其中两个就行啦,一个设置成NAT方式,一个设置成brige方式。
