-스크립트실행시-

device_name 쪽은 장치명을 적습니다. [ ex ) eth ]

IPADDR 쪽은 bond에 들어갈 ip주소를 적습니다. [ ex ) 192.168.189.10 ]

NETMASK 쪽은 NETMASK를 적습니다 [ ex ) 255.255.255.0 ]

GATEWAY 쪽은 GATEWAY IP를 적습니다 [ ex ) 192.168.189.254 ]

[root@centos6 ~]# sh bonding.sh
device_name : eth
IPADDR : 192.168.189.10
NETMASK : 255.255.255.0
GATEWAY : 192.168.189.254
[root@centos6 ~]# service network restart

-스크립트 실행후 확인-

bond0으로 IP올라온것 확인가능

기존의 네트워크 설정은 네트워크 설정 경로의 .back파일로 만들어집니다. [ ex ) eth0.back , eth1.back ]

가끔식 네트워크 시작이 0이아닌 1로 되는 경우도있으니 상황에 따라 수정해주세요
