it 動力總結(jié)系統(tǒng)安裝好后,通過以下二個步驟就可以讓你的系統(tǒng)正常上網(wǎng)(大多正常情況下)。
步驟1、配置/etc/sysconfig/network-scripts/ifcfg-eth0 里的文件。it動力的CentOS下的ifcfg-eth0的配置詳情:
[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
前面三行是系統(tǒng)睚帶的,后面就是手動添加的。
這樣設(shè)置扣,記得重啟網(wǎng)卡:
[root@localhost ~]# /etc/init.d/network stop
[root@localhost ~]# /etc/init.d/network start
行了,現(xiàn)在就可以PING得通網(wǎng)關(guān)了,如果還得上網(wǎng),不必須設(shè)置DNS。設(shè)置DNS就詳見步驟2
步驟2、修改dns
[root@localhost ~]# vi /etc/resolv.conf
在里面添加二個dns:
nameserver 202.96.134.133
nameserver 8.8.8.8
ok,大攻告成,即可上網(wǎng)了!?。?!
以下是參考,如果按上面步驟不行,可以詳細看以下內(nèi)容:
網(wǎng)絡(luò)接口配置文件
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
TYPE=Ethernet #網(wǎng)卡類型
DEVICE=eth0 #網(wǎng)卡接口名稱
ONBOOT=yes #系統(tǒng)啟動時是否自動加載
BOOTPROTO=static #啟用地址協(xié)議 --static:靜態(tài)協(xié)議 --bootp協(xié)議 --dhcp協(xié)議
IPADDR=192.168.1.11 #網(wǎng)卡IP地址
NETMASK=255.255.255.0 #網(wǎng)卡網(wǎng)絡(luò)地址
GATEWAY=192.168.1.1 #網(wǎng)卡網(wǎng)關(guān)地址
DNS1=10.203.104.41 #網(wǎng)卡DNS地址
HWADDR=00:0C:29:13:5D:74 #網(wǎng)卡設(shè)備MAC地址
BROADCAST=192.168.1.255 #網(wǎng)卡廣播地址
重新導(dǎo)入ifcfg-eth0網(wǎng)絡(luò)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 ]
網(wǎng)卡接口關(guān)閉與激活
[root@localhost ~]# ifdown eth0 #關(guān)閉網(wǎng)絡(luò)
[root@localhost ~]# ifup eth0 #啟動網(wǎng)絡(luò)
網(wǎng)絡(luò)服務(wù)啟動與關(guān)閉
方法一:
[root@localhost ~]# service network stop #關(guān)閉網(wǎng)絡(luò)服務(wù)
[root@localhost ~]# service network start #啟動網(wǎng)絡(luò)服務(wù)
[root@localhost ~]# service network restart #重啟網(wǎng)絡(luò)服務(wù)
方法二:
[root@localhost ~]# /etc/init.d/network stop
[root@localhost ~]# /etc/init.d/network start
[root@localhost ~]# /etc/init.d/network restart
網(wǎng)卡狀態(tài)查詢
[root@localhost ~]# service network status
Configured devices:
lo eth0
Currently active devices:
lo eth0
臨時配置網(wǎng)卡信息,無需重啟。
[root@localhost ~]# ifconfig eth0 10.1.1.10 netmask 255.0.0.0
查看網(wǎng)卡接口信息,默認列出所有接口
