ifconfig eth0 新ip
然后编辑/etc/sysconfig/network-scripts/ifcfg-eth0，修改ip
一、修改IP地址
[aeolus@db1 network-scripts]$ vi ifcfg-eth0
DEVICE=eth0
onBOOT=yes
BOOTPROTO=static
IPADDR=219.136.241.211
NETMASK=255.255.255.128
GATEWAY=219.136.241.254
二、修改网关
vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=Aaron
GATEWAY=192.168.1.1
三、修改DNS
[aeolus@db1 etc]$ vi resolv.conf
nameserver 202.96.128.68
nameserver 219.136.241.206
四、重新启动网络配置
/etc/init.d/network restart
修改ip地址
即时生效:
# ifconfig eth0 192.168.0.20 netmask 255.255.255.0
启动生效:
修改/etc/sysconfig/network-scripts/ifcfg-eth0
修改default gateway
即时生效:
# route add default gw 192.168.0.254
启动生效:
修改/etc/sysconfig/network-scripts/ifcfg-eth0
修改dns
修改/etc/resolv.conf
修改后可即时生效，启动同样有效
修改host name
