The first thing to do after installing Linux is to set an IP address for Internet access. This article describes how
. Set static IP address.
(1). set the command line (this method is only temporary and will not expire after the system is restarted)
[1]. set IP address and mask
Ifconfig interface name (such as eth0) IP address netmask subnet mask
[2]. set the Gateway
Route add default gw default gateway
[3]. set the DNS server address
Echo "nameserver DNS server address">/etc/resolv. conf
Instance: assume that the IP address of eth0 is 192.168.1.100 and DNS is 192.168.1.12.
Ifconfig eth0 192.168.1.100 netmask 255.255.255.0
Route add default gw 192.168.1.1
Echo "nameserver = 192.168.1.12">/etc/resolv. conf
(2). modify the file to configure the network (you need to restart the network interface)
[1]. modify the IP address. File:/etc/sysconfig/network-scripts/ifcfg-interface name
Assume that the network interface name is eth0.
Cat < /Etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE = eth0 (note: the network interface name is entered here)
BOOTPROTO = none
ONBOOT = yes (note: whether to start with the system)
IPADDR = 192.168.1.100 (note: the IP address is entered here)
PREFIX = 24 (note: The mask length is entered here)
GATEWAY = 192.168.1.1 (note: The GATEWAY is written here)
EOF
[2]. modify DNS
Echo "nameserver DNS server address">/etc/resolv. conf
[3]. restart the network interface (assuming eth0)
Ifup eth0 (note: The Interface name is written here)
