    步骤1、配置/etc/sysconfig/network-scripts/ifcfg-eth0 里的文件。it动力的CentOS下的ifcfg-eth0的配置详情:

    [root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0

    DEVICE="eth0"
    HWADDR="00:0C:29:FD:FF:2A"
    NM_CONTROLLED="yes"
    ONBOOT="yes"
    IPADDR=192.168.1.31
    NETMASK=255.255.255.0
    GATEWAY=192.168.1.1
    BOOTPROTO=static

    前面三行是系统睚带的,后面就是手动添加的。
    这样设置扣,记得重启网卡:
    [root@localhost ~]# /etc/init.d/network stop
    [root@localhost ~]# /etc/init.d/network start

    行了,现在就可以PING得通网关了,如果还得上网,不必须设置DNS。设置DNS就详见步骤2

    步骤2、修改dns
    [root@localhost ~]# vi /etc/resolv.conf 
    在里面添加二个dns:
    nameserver 202.96.134.133
    nameserver 8.8.8.8

    ok,大攻告成,即可上网了!!!!

    以下是参考,如果按上面步骤不行,可以详细看以下内容:
    网络接口配置文件
    [root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
    # Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
    TYPE=Ethernet       #网卡类型
    DEVICE=eth0         #网卡接口名称
    ONBOOT=yes          #系统启动时是否自动加载
    BOOTPROTO=static    #启用地址协议 --static:静态协议 --bootp协议 --dhcp协议
    IPADDR=192.168.1.11      #网卡IP地址
    NETMASK=255.255.255.0    #网卡网络地址
    GATEWAY=192.168.1.1      #网卡网关地址
    DNS1=10.203.104.41       #网卡DNS地址
    HWADDR=00:0C:29:13:5D:74 #网卡设备MAC地址
    BROADCAST=192.168.1.255  #网卡广播地址 
    重新导入ifcfg-eth0网络配置文件
    [root@localhost ~]# /etc/init.d/network reload
    Shutting down interface eth0:                             [ OK ]
    Shutting down loopback interface:                         [ OK ]
    Bringing up loopback interface:                           [ OK ]
    Bringing up interface eth0:                               [ OK ]

    网卡接口关闭与激活
    [root@localhost ~]# ifdown eth0   #关闭网络
    [root@localhost ~]# ifup eth0     #启动网络

    网络服务启动与关闭
    方法一:
    [root@localhost ~]# service network stop    #关闭网络服务
    [root@localhost ~]# service network start   #启动网络服务
    [root@localhost ~]# service network restart #重启网络服务
    方法二:
    [root@localhost ~]# /etc/init.d/network stop
    [root@localhost ~]# /etc/init.d/network start
    [root@localhost ~]# /etc/init.d/network restart 
    网卡状态查询
    [root@localhost ~]# service network status
    Configured devices:
    lo eth0
    Currently active devices:
    lo eth0

    临时配置网卡信息,无需重启。
    [root@localhost ~]# ifconfig eth0 10.1.1.10 netmask 255.0.0.0
    查看网卡接口信息,默认列出所有接口
    [root@localhost ~]# ifconfig

    查看当前路由及网关信息
    [root@localhost ~]# netstat -r
