CentOS6 Interface 4개 Bonding으로 대역폭 상승 시키기

1. bond0 만들기

[root@localhost network-scripts]#cd /etc/sysconfig/network-scripts
[root@localhost network-scripts]# vi ifcfg-bond0
=====================================
DEVICE=bond0
BOOTPROTO=none
ONBOOT=yes
USERCTL=no
TYPE=Ethernet
IPADDR=192.168.100.100
NETMAST=255.255.255.0
BONDING_MASTER=yes
BONDING_OPTS="mode=4 miimon=100"
======================================

Bonding Mode 설명

mode=0

 - round robine : NIC를 통한 분배 (부하분산)

mode=1

 - active-standy : active상태의 NIC 문제 발생 시 standby 활성화

mode=2

 - Balance-XOR : 0과 비슷 하지만 xor연산을 이용한 Mac을 이용한 분배

mode=3

 - Broadcast 정책 : 2개의 NIC에 어떤 규칙 없이 데이터 통신 

mode=4

 - 802.3ad : 이 기능을 사용 하기 위해서는 switch에서 aggregation 그룹 생성이 필요

                대역폭 상승 기능

 

2. ifcfg-XXXX 장치 master = bond0 등록

장치명 p3p1,p3p2,p3p3,p3p4  MASTER=bond0

[root@localhost network-scripts]# cat ifcfg-p3p1
==============================================
DEVICE=p3p1
MASTER=bond0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
USERCTL=no
PEERDNS=yes
IPV6INIT=no
SLAVE=yes
==============================================

3. bonding 환경 설정 값 변경

[root@localhost network-scripts]# vi /etc/modprobe.d/bonding.conf
==========================================
alias bond0 bonding
options bonding mode=4 miimon=100
==========================================

4. network restart

 # service network restart

 

5. bonding 확인

[root@localhost network-scripts]# cat /proc/net/bonding/bond0
