How do I configure the Internet Protocol version 4 (IPv4) properties of a network connection with a static IP address for servers running Linux operating systems? How do I configure static IP address under Debian Linux or Redhat Enterprize/ RHEL / Fedora / Sent OS / Ubantu / Redhat Enterprise Linux server?

If you are edit, setup or update IP address that you will flow this system . I wrote Tow kinds of Linux IP setup System .

       2 . Command Mode
   You are At First open Terminal
   Red Hat / Fedora / CentOS IP Configuration Files:
   The Red Hat configuration tools store the configuration information in the file /etc/sysconfig/network.
   They will also allow one to configure routing information. 

   /sbin/ifconfig eth0 192.168.10.12 netmask 255.255.255.0 broadcast 192.168.10.255

    Static IP address Configuration: (Configure gateway address)
       # /etc/sysconfig/network
   Assign IP/Subnet: ifconfig eth0 192.168.1.2 netmask 255.255.255.0
   Assign Default Gateway: route add default gw 192.168.1.1 
   Other setup system  in Linux
   
   [root@baboo]# cd /etc/sysconfig/network-scripts/ Every network interface will have it’s own interface script file. eth0,eth1,eth2 and so on. Vi the ifcfg-eth0 interface script file for interface eth0. Replace the contents of the ifcfg-eth0 file with the parameters below.
   [root@baboo]# vi ifcfg-eth0.

DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
IPADDR=192.168.1.2
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
   If you configure DHCP setup Configure than 
   If you want to switch back to DHCP, repeat the steps above and replace the contents of the ifcfg-eth0 file with the parameters below.
   DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:0F:20:71:0A:50
ONBOOT=yes
TYPE=Ethernet
DHCP_HOSTNAME=klmdrpdr01p.klm1.netcel360.com
    
   Restart your interface to apply the changes.
   
[root@baboo]#ifdown eth0
[root@baboo]#ifup eth0 
   [root@baboo]#service network restart 
   

   Or
   [root@baboo]#/etc/init.d/networking restartwww.newstips24.blogspot.com
