Linux修改IP

ifconfig eth0 新ip而后编辑/etc/sysconfig/network-scripts/ifcfg-eth0，修改ip[aeolus@db1 network-scripts]$ vi ifcfg-eth0 DEVICE=eth0ONBOOT=yesBOOTPROTO=staticIPADDR=219.136.241.211NETMASK=255.255.255.128GATEWAY=219.136.241.254[aeolus@db1 etc]$ vi resolv.conf nameserver 202.96.128.68nameserver 219.136.241.206－－－－－－－－－－－－－－－－－－－－－－－Linux下修改网卡IP和网关建议经过终端字符方式下来修改一修改IP地址vi /etc/sysconfig/network-scripts/ifcfg-eth0DEVICE=eth0BOOTPROTO=noneBROADCAST=192.168.1.255IPADDR=192.168.1.33NETMASK=255.255.255.0NETWORK=192.168.1.0ONBOOT=yesUSERCTL=noPEERDNS=noTYPE=Ethernet~vi /etc/sysconfig/network-scripts/ifcfg-eth1DEVICE=eth1ONBOOT=yesBOOTPROTO=noneIPADDR=192.168.2.34NETMASK=255.255.255.0USERCTL=noPEERDNS=noTYPE=EthernetNETWORK=192.168.2.0BROADCAST=192.168.2.255二修改网关vi /etc/sysconfig/networkNETWORKING=yesHOSTNAME=AaronGATEWAY=192.168.1.1三从新启动网络配置/etc/init.d/network restart-----------------------------------------------------------------------------------修改配置文件/etc/sysconfig/network-scripts/ 下有配置文件好比文件：ifcfg-eth0 表明是以太网实际网卡0的配置文件好比文件：ifcfg-eth0:1 表明是以太网实际网卡0的配置文件域名服务器配置文件：/etc/ resolv.conf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，启动一样有效修改host name即时生效:# hostname fc2启动生效:修改/etc/sysconfig/network
