[Bonding] CentOS / RHEL bonding 구성
1. /etc/modprobe.d/bonding.conf 생성 및 설정
# vi /etc/modprobe.d/bonding.conf
alias bond0 bonding
alias bond1 bonding // 두개일 경우
2. NetworkManager 서비스 실행 여부 확인 필요(실행 시 Bonding 구성 안됨)
service NetworkManager stop
chkconfig NetworkManager off
3. 설정파일 수정
# vi /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
BOOTPROTO=none
ONBOOT=yes
IPADDR=xxx.xxx.xxx.xxx
NETMASK=255.255.255.0
GATEWAY=xxx.xxx.xxx.1
BONDING_OPTS="mode=1 miimon=100"
USERCTL=no
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=YES
HWADDR=00:00:00:00:00:00
MASTER=bond0
SLAVE=yes
USETCTL=no
4. 본딩 절체테스트
- 터미널 1번 -
# watch -n1 cat /proc/net/bonding/bond0
- 터미널 2번 -
ping GATEWAY IP
- 이후 네트워크 케이블 절체 시 ping 빠짐 현상 및 인터페이스 전환 확인 -
- ifenslave -c bond0 eth4 // 명령어를 통한 절체도 확인
ex) watch -n1 cat /proc/net/bonding/bond0
