Centos6下网卡启动、配置ifcfg-eth0教程

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-eth0DEVICE="eth0"HWADDR="00:0C:29:FD:FF:2A"NM_CONTROLLED="yes"ONBOOT="yes"IPADDR=192.168.1.31NETMASK=255.255.255.0GATEWAY=192.168.1.1BOOTPROTO=static前面三行是系统自带的,后面就是手动添加的 。
这样设置,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 reloadShutting 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 statusConfigured devices:lo eth0Currently 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 ~]# ifconfigeth0Link encap:EthernetHWaddr 00:0C:29:13:5D:74inet addr:192.168.1.11Bcast:192.168.1.255Mask:255.255.255.0inet6 addr: fe80::20c:29ff:fe13:5d74/64 Scope:LinkUP BROADCAST RUNNING MULTICASTMTU:1500Metric:1RX packets:413 errors:0 dropped:0 overruns:0 frame:0TX packets:572 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:47701 (46.5 KiB)TX bytes:64842 (63.3 KiB)Base address:0x2000 Memory:d8920000-d8940000loLink encap:Local Loopbackinet addr:127.0.0.1Mask:255.0.0.0inet6 addr: ::1/128 Scope:HostUP LOOPBACK RUNNINGMTU:16436Metric:1RX packets:407 errors:0 dropped:0 overruns:0 frame:0TX packets:407 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:0RX bytes:70759 (69.1 KiB)TX bytes:70759 (69.1 KiB)查看当前路由及网关信息
