ifconfigeth0新ip
然后编辑/etc/sysconfig/network-scripts/ifcfg-eth0,修改ip 一、修改IP地址 [aeolus@db1network-scripts]$viifcfg-eth0 DEVICE=eth0 ONBOOT=yes BOOTPROTO=static IPADDR=219.136.241.211 NETMASK=255.255.255.128 GATEWAY=219.136.241.254 二、修改网关 vi/etc/sysconfig/network NETWORKING=yes HOSTNAME=Aaron GATEWAY=192.168.1.1 三、修改DNS [aeolus@db1etc]$viresolv.conf nameserver202.96.128.68 nameserver219.136.241.206 四、重新启动网络配置 /etc/init.d/networkrestart 修改ip地址 即时生效: #ifconfigeth0192.168.0.20netmask255.255.255.0 启动生效: 修改/etc/sysconfig/network-scripts/ifcfg-eth0 修改defaultgateway 即时生效: #routeadddefaultgw192.168.0.254 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hostname 即时生效: #hostnamefc2 启动生效: 修改/etc/sysconfig/network
