使用setup命令,在图形环境下修改,或修改配置文件:

Edit configuration files stored in /etc/sysconfig/network-scripts/

You can configure network card by editing text files stored in /etc/sysconfig/network-scripts/ directory. First change directory to /etc/sysconfig/network-scripts/:
# cd /etc/sysconfig/network-scripts/
You need to edit / create files as follows:

/etc/sysconfig/network-scripts/ifcfg-eth0 : First Ethernet card configuration file
/etc/sysconfig/network-scripts/ifcfg-eth1 : Second Ethernet card configuration file

To edit/create first NIC file, type command:
# vi ifcfg-eth0
Append/modify as follows:
# Intel Corporation 82573E Gigabit Ethernet Controller (Copper) DEVICE=eth0 BOOTPROTO=static DHCPCLASS= HWADDR=00:30:48:56:A6:2E IPADDR=10.10.29.66 NETMASK=255.255.255.192 ONBOOT=yes

Save and close the file. Define default gateway (router IP) and hostname in /etc/sysconfig//network file:
# vi /etc/sysconfig/network
Append/modify configuration as follows:
NETWORKING=yes HOSTNAME=www1.nixcraft.in GATEWAY=10.10.29.65

Save and close the file. Restart networking:
# /etc/init.d/network restart
