Linux服务器修改IP地址、网关

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
