[리눅스] CentOS 6, 7 Bonding 설정

CentOS 6, 7 bonding(본딩) 설정입니다.

 

Bonding Module 설정

1. 본딩 모듈 추가

[root@eloquence ~]# vi /etc/modprobe.d/bonding.conf alias bond0 bonding options bonding mode=1 miimon=100  // mode=0 : Round Robin  mode=1 : Active-Backup

 

2. 본딩 모듈 로드

[root@eloquence ~]# modprobe --first-time bonding [root@eloquence ~]# lsmod | grep bonding bonding                   188416   0

 

3. 본딩 모듈 정보

[root@eloquence ~]# modinfo bonding filename:            /lib/modules/4.18.0-193.el8.x86_64/kernel/drivers/net/bonding/bonding.kr.xz author:              Thomas Davis,  tadavis@lbl.gov and many others description:        Ethernet Channel Bonding Driver, v3.7.1 version:             3.7.1 license:              GPL alias:                 rtnl-link-bond rhelversion:        8.2 (생략) . . .

 

Bonding Interface 설정

1. 본딩 인터페이스 생성

[root@eloquence ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond0 DEVICE=bond0 NAME=bond0 TYPE=Bond IPADDR=192.168.0.100 NETMASK=255.255.255.0 GATEWAY=192.168.0.254 ONBOOT=yes BOOTPROTO=none BONDING_OPTS="mode=1 miimon=100"

 

2. 슬레이브 인터페이스 생성

[root@eloquence ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno1 DEVICE=eno1 NAME=bond-slave-eno1 TYPE=Ethernet ONBOOT=yes BOOTPROTO=none MASTER=bond0 SLAVE=yes [root@eloquence ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno2 DEVICE=eno2 NAME=bond-slave-eno2 TYPE=Ethernet ONBOOT=yes BOOTPROTO=none MASTER=bond0 SLAVE=yes

 

 

network 서비스 재시작

1. NetworkManager 정지 및 비활성화

[root@eloquence ~]# systemctl stop NetworkManager [root@eloquence ~]# systemctl disable NetworkManager

 

2. network 재시작

[root@eloquence ~]# systemctl restart network

 

Bonding 구성 확인

1. 인터페이스 확인

[root@eloquence ~]# nmcli d DEVICE   TYPE        STATE       CONNECTION bond0    bond     connected        bond0 eno1    ethernet   connected  bond-slave-eno1 eno2    ethernet   connected  bond-slave-eno2

 

절체 테스트

1. active-backup Fault-Tolerance 테스트

[root@eloquence ~]# watch -n1 cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: eno1 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eno1 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 08:94:ef:16:31:c7 Slave queue ID: 0 Slave Interface: eno2 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 08:94:ef:16:31:c8 Slave queue ID: 0 ※. 물리적으로 eno1 이더넷 케이블을 뽑았을 때 eno1 status : down 상태로 되었으며, Active가 eno1 → eno2로 변경됨을 확인 [root@eloquence ~]# watch -n1 cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: eno2 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eno1 MII Status: down Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 08:94:ef:16:31:c7 Slave queue ID: 0 Slave Interface: eno2 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 08:94:ef:16:31:c8 Slave queue ID: 0
