[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 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:2a:4a:16:01:5b brd ff:ff:ff:ff:ff:ff inet 192.168.13.63/16 brd 192.168.255.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::22a:4aff:fe16:15b/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 state UP group default qlen 1000 link/ether 00:2a:4a:16:01:63 brd ff:ff:ff:ff:ff:ff 4: eth2: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 state UP group default qlen 1000 link/ether 00:2a:4a:16:01:63 brd ff:ff:ff:ff:ff:ff 5: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:2a:4a:16:01:63 brd ff:ff:ff:ff:ff:ff inet 10.0.0.1/24 brd 10.0.0.255 scope global bond0 valid_lft forever preferred_lft forever inet6 fe80::22a:4aff:fe16:163/64 scope link valid_lft forever preferred_lft forever
위와 같이 bonding 구성이 된것을 확인 할 수 있습니다.
