linux 修改IP, DNS 命令 http://www.cnblogs.com/fighter/archive/2010/03/04/1678007.html
修改DNS
[root@localhost network-scripts]# vi /etc/sysconfig/network-scripts/resolv.conf
nameserver 202.98.96.68
nameserver 61.139.2.69
重新啟動網絡配置
/etc/init.d/network restart
linux 下 ifcfg-eth0 配置 http://www.cnblogs.com/iixiaowei/articles/2300084.html
網絡接口配置文件 [root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) TYPE=Ethernet #網卡類型 DEVICE=eth0 #網卡接口名稱 ONBOOT=yes #系統啟動時是否自動加載 BOOTPROTO=static #啟用地址協議 --static:靜態協議 --bootp協議 --dhcp協議 IPADDR=192.168.1.11 #網卡IP地址 NETMASK=255.255.255.0 #網卡網絡地址 GATEWAY=192.168.1.1 #網卡網關地址 DNS1=10.203.104.41 #網卡DNS地址 HWADDR=00:0C:29:13:5D:74 #網卡設備MAC地址 BROADCAST=192.168.1.255 #網卡廣播地址
重新導入ifcfg-eth0網絡配置文件 [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 ] 網卡接口關閉與激活 [root@localhost ~]# ifdown eth0 #關閉網絡 [root@localhost ~]# ifup eth0 #啟動網絡 網絡服務啟動與關閉 方法一: [root@localhost ~]# service network stop #關閉網絡服務 [root@localhost ~]# service network start #啟動網絡服務 [root@localhost ~]# service network restart #重啟網絡服務 方法二: [root@localhost ~]# /etc/init.d/network stop [root@localhost ~]# /etc/init.d/network start [root@localhost ~]# /etc/init.d/network restart 網卡狀態查詢 [root@localhost ~]# service network status Configured devices: lo eth0 Currently active devices: lo eth0
查看當前路由及網關信息 [root@localhost ~]# netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth0 default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
