update redhat dynamic IP to static IP

update redhat dynamic IP to static IP

 

step1: add gateway 

     vi /etc/sysconfig/network 

     add below "GATEWAY" line 

NETWORKING=yes 

NETWORKING_IPV6=no 

HOSTNAME=localhost.localdomain 

GATEWAY=192.168.1.1 

  www.2cto.com  

step2: add your new IP address 

      update dhcp to static, 

      add your ipaddr line 

      add your netmast line 

 

DEVICE=eth0 

#BOOTPROTO=dhcp 

BOOTPROTO=static 

HWADDR=00:CC:23:3A:C3:EF 

IPADDR=192.168.1.200 

NETMAST=255.255.255.0 

ONBOOT=yes 

 

step3: update name server 

vi /etc/resolv.conf 

nameserver x.y.z.p 

(normal, below step won't need, cause it will automaticlly get your name server) 

 

step4:verify the static ip config effect: 

ifconfig eth0
