以下各值常见于所有的基本配置文件中：* DEVICE=name,这里name是物理设备的名字（动态分配的PPP设备应当除外，它的名字是“逻辑名”。* IPADDR=addr, 这里addr是IP地址。* NETMASK=mask, 这里mask是网络掩码。* NETWORK=addr, 这里addr是网络地址。* BROADCAST=addr, 这里addr是广播地址。* GATEWAY=addr, 这里addr是网关地址。* ONBOOT=answer, 这里answer取下列值之一：o yes -- 该设备将在boot时被激活。o no -- 该设备不在boot时激活。* USERCTL=answer, 这里answer取下列值之一：o yes --非root用户可以控制该设备。o no -- 非root用户不允许控制该设备。* BOOTPROTO=proto, 这里proto取下列值之一：o none -- 不使用boot时协议。o bootp -- 使用bootp协议。o dhcp --使用dhcp协议。终端:查询IP地址: ifconfig -a修改局域网IP:1.以 root 登录2.修改配置文件/etc/sysconfig/network-scripts/ifcfg-eth0文件内容如下：\DEVICE=eth0HWADDR=00:0C:29:A2:8C:B2ONBOOT=yesTYPE=EthernetNETMASK=255.255.255.0 IPADDR=192.168.1.11 -> 修改为 192.168.1.12GATEWAY=192.168.1.1 reboot
ifconfig eth0 新ip 然后编辑/etc/sysconfig/network-scripts/ifcfg-eth0，修改ip
