Set a static IP address for the machine under Linux:
Vim/etc/sysconfig/network-scripts/ifcfg-eth0
Modify the contents of this file in the following form:
# Intel Corporation 82541GI Gigabit Ethernet Controller
Device=eth0
Bootproto=static #为静态的
Hwaddr=00:15:17:b2:dc:b5
Onboot=yes
ipaddr=10.20.134.199 #这个是设置的静态IP地址
netmask=255.255.254.0
gateway=10.20.134.1 #网关
After modification, the need to restart the network is changed to take effect:/etc/init.d/network Restart, automatically get dynamic IP address mode:
Vim/etc/sysconfig/network-scripts/ifcfg-eth1
The contents are as follows:
# Intel Corporation 82566dm-2 Gigabit Network Connection
Device=eth1
Bootproto=dhcp #动态获取IP
Hwaddr=00:15:17:b2:dc:b7
Onboot=no
Run command:dhclient eth1 , automatically get the dynamic IP address, you can view the assigned IP address by: ifconfig.
Vim/etc/resolv.conf
