Linux 修改IP及虚拟网卡配置详解

修改IP地址及MAC地址：
[[email?protected] ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0?
DEVICE=eth0 #网卡设备名称?
BOOTPROTO=static #协议类型 dhcp bootp none?
BROADCAST=172.29.165.255 #广播地址?
IPADDR=172.29.165.152 #网络IP地址?
NETMASK=255.255.255.0 #网络子网地址?
NETWORK=172.29.165.0 #网络ID?
ONBOOT=yes #启动时是否激活 yes|no?
HWADDR=00:1E:90:45:A3:25#网卡MAC地址?
GATEWAY=172.29.165.254 #网关地址

修改网关
[[email?protected] ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=rac1
#修改HOSTNAME的同时必须修改 /etc/hosts 文件

修改DNS
[[email?protected] ~]# vi /etc/resolv.conf?
# Generated by NetworkManager
nameserver 172.29.131.15
nameserver 172.29.131.14
nameserver 172.29.131.2

创建虚拟网卡

[[email?protected] ~]# cd /etc/sysconfig/network-scripts/ ?
cp ifcfg-eth0 ifcfg-eth0:1

?

[[email?protected] network-scripts]# vi ifcfg-eth0:1?DEVICE=eth0:1 #网卡设备名称BOOTPROTO=static #协议类型 dhcp bootp none?IPADDR=172.29.165.211 #网络IP地址?NETMASK=255.255.255.0 #网络子网地址ONBOOT=yes
