Configure Static IP On CentOS 6
Below steps will show configuration to set static IP address in Cent-OS machine.
Network configuration files are under "/etc/sysconfig/network-scripts".
We can open the file with editor like nano, vi, vim etc...
Here I will use vi editor.
In this server we will set Static IP for eth0 Ethernet port
1 - Start your server running Cent-OS enter root user credentials and login.
2 - Type the command,
vi /etc/sysconfig/network-scripts/ifcfg-eth0
This will open network configuration file, edit below lines:
NM_CONTROLLED=yes
ONBOOT=yes
TYPE=Ethernet
BOOTPROTO=static
IPADDR=192.168.1.44 # Replace IP with your new
NETMASK=255.255.255.0 # Replace IP with your subnet mask
3 - Type the command,
vi /etc/sysconfig/network
This will open file to set default gateway, edit below lines:
NETWORKING=yes
GATEWAY=192.168.1.1 # Replace IP with your gateway IP
4 - Type the command,
vi /etc/resolv.conf
This will open file to set DNS,
nameserver 8.8.8.8 # Replace IP with your DNS IP
nameserver 192.168.1.1 # Replace IP with your DNS IP
5 - To apply changes restart network interface, Type the command.
/etc/init.d/network restart
NOTE:
Some time you might face issue in accessing your system. It can be due to firewall.
To stop firewall temporary execute command,
service iptables stop
To stop firewall permanently execute command,

chkconfig iptables off
ENJOY! and Stay connected.

Modify host-name in Cent-OS 6
To change host name you must have root access of the system. We can do it using any text editor, here I am using text editor "vim".
Open /etc/sysconfig/network file.
[root@lmntechnohub ~]# vim /etc/sysconfig/network
Modify the HOSTNAME= value, and set your new host name.
HOSTNAME=lmntechnohub.com
For internal networking, change the entries in host files at /etc/hosts .
127.0.0.1 localhost localhost.localdomain
10.10.10.10 lmntechnohub.com
Run the host-name command. This command will change host-name of Linux server, but it will not immediately update all programs that are running with old host-name.
[root@lmntechnohub ~]# hostname lmntechnohub.com
[root@lmntechnohub ~]# hostname
lmntechnohub.com
[root@lmntechnohub ~]#
To finalize it restart network service on your system, to ensure that changes will there on system restart.
[root@lmntechnohub ~]# /etc/init.d/network restart
ENJOY! and Stay connected.
