Linux boot Nic method

The ifconfig command can be used to view information such as Linux active network adapters and IP addresses, subnet masks, or MAC addresses

[Root@localhost ~]# Ifconfig
Eth0 Link encap:ethernet hwaddr 08:00:27:d4:71:2d
inet addr:192.168.1.104 bcast:255.255.255.255 mask:255.255.255.0

Eth0 is a Linux host of a network card, lo is the local loop

Ifconfig eth0 up #可以用于启动网卡
Ifconfig eth0 down #可以用于禁用网卡
Ifconfig eth0 192.168.1.101 #可以给主机制定静态地址

If you want to use DHCP assignment, you can use the Dhclient command
Enter dhclient directly in the terminal:
