  CentOS / Linux NIC set IP address configuration
  Add Date : 2017-08-31      
  Set the IP address of the next CentOS / Linux

1: Temporary Review:
1.1: Modify IP address
# Ifconfig eth0

1.2: Modify the gateway address
# Route add default gw dev eth0

1.3: Edit DNS
# Echo "nameserver" >> /etc/resolv.conf

This time on the Internet, the Internet's IP address is, gateway address But this setting is temporary, once the card restart or reboot the server, in addition to other actions 1.3 will be reduced, this approach is only suitable for temporary IP changes, you want to permanently modify the network card configuration file, you need to modify the appropriate file

2: Permanently Review:
2.1: Modify IP address
Modify / etc / sysconfig / network-scripts / ifcfg-eth0 file, if multiple network cards, modify the corresponding card
# Vi / etc / sysconfig / network-scripts / ifcfg-eth0
DEVICE = eth0 # NIC corresponding device alias
Information BOOTPROTO = static # NIC obtain ip address (the default is dhcp, showing automatically obtain)
HWADDR = 00: 07: E9: 05: E8: B4 # MAC address (physical address)
IPADDR = #IP address
NETMASK = # Subnet Mask
ONBOOT = yes # system is activated when the device starts

2.2: Modify the gateway address
Modify / etc / sysconfig / network file
# Vi / etc / sysconfig / network
NETWORKING = yes # indicates whether the system is using the network, no network that they can not use
HOSTNAME = doiido # Set the host name of the machine, and to / etc / hosts set the same host name
GATEWAY = # Set the gateway IP address

This time can already ping the IP address, but can not ping the domain name, and therefore need to modify the DNS

2.3: Edit DNS
Modify /etc/resolv.conf file
# Vi /etc/resolv.conf
nameserver #google domain name server
domestic domain name server nameserver #

2.4: Restart NIC
# Service network restart
Turning off the interface eth0: [OK]
Close the loopback interface: [OK]
Pop the loopback interface: [OK]
Pop-up interface eth0: [OK]

This time, the system can normally get online

# Note: In fact, gateway address, and DNS can also write in ifcfg-eth0, but for regulatory purposes, they will write separately
