Temporary, permanent modification of IP in Linux

Temporarily modify IP

Enter the command in Linux: ifconfig eth0 192.168.1.1 netmask 255.255.255.0 Enter

Here the 192.168.1.1 is the temporary ip,netmask is the subnet mask, this temporary IP will be changed after you restart the network card to the previous IP

Permanently modify IP

Entering commands in Linux

# Vim/etc/sysconfig/network-scripts/ifcfg-eth0, new or modified in Ifcfg-eth0 file

ipaddr=192.168.1.1

netmask=255.255.255.0

# wq!

Restart the NIC after saving

# Service Network Restart

# ifconfig

Now that the IP address is 192.168.1.1, if you find that your IP address is still unchanged, go to the Ifcfg-eth0 file to view

bootproto= ' DHCP ' dynamic acquisition of IP

Revision changed to

bootproto= ' static ' to obtain IP statically

# Service Network Restart

# ifconfig

At this time the IP address should already be 192.168.1.1

Note the point:

1. The temporary IP will restart the network card, the IP is restored to the previous

2. Permanent IP modification requires a network card restart
