[Linux] CentOS 7 네트워크 Bonding 구성

CentOS 7 에서 bonding 구성을 위해서는 아래와 같은 절차가 필요합니다.

CentOS 7 에서는 bonding 모듈이 기본적으로 로드가 되어 있지 않습니다. 아래 명령을 통해 boning 모듈을 로드합니다.

# modprobe --first-time bonding

Bond Interface 생성 Bond Interface 생성을 하기위해서는 /etc/sysconfig/network-scripts/ 의 ifcfg-bond0 파일을 생성해야됩니다.

# cat  /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
NAME=bond0
TYPE=Bond
IPADDR=10.0.0.1
NETMASK=255.255.255.0
ONBOOT=yes
BOOTPROTO=none
BONDING_OPTS="mode=1 miimon=100"

SLAVE Interface 생성 bond Interface 의 SLAVE Interface 파일을 생성합니다.
/etc/sysconfig/network-scripts/ 의 ifcfg-eth1 과 ifcfg-eth2 를 수정합니다.

# cat ifcfg-eth1
DEVICE=eth1
NAME=eth1
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
# cat ifcfg-eth2
DEVICE=eth2
NAME=eth2
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes

NetworkManager disable && network restart network 재시작을 합니다.

# systemctl disable NetworkManager
# systemctl stop NetworkManager
# systemctl restart network
# ip a

위와 같이 bonding 구성이 된것을 확인 할 수 있습니다.
