Linux CentOS5.5 的 IP设置

1.IP设置

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

设置静态ip
DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.1.102
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
HWADDR=00:0C.....
ONBOOT=yes
TYPE=Ethernet

动态IP
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:0C...
ONBOOT=yes

2.DNS设置

vim /etc/resolv.conf

配置DNS
nameserver 202.96.128.166

3.增加一个虚拟IP

ifconfig eth0:1 192.168.1.134 netmask 255.255.255.0 up

但是重启网络服务后.就会消失

service network restart

4. 删除一个虚拟ip

ip addr del 192.168.1.134 dev eth0

5.查看IP

[root@xuwu /]# ifconfig
