CentOS 6配置Bonding多网卡

1. 关闭和停止NetworkManager服务

# service  NetworkManager stop
# chkconfig NetworkManager off

2、加载bonding模块

# modprobe --first-time bonding

没有提示说明加载成功, 如果出现modprobe: ERROR: could not insert 'bonding': Module already in kernel说明你已经加载了这个模块, 就不用管了

3、创建基于bond0接口的配置文件

# vi /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
TYPE=Bond
BOOTPROTO=none
ONBOOT=yes
USERCTL=no
IPADDR="172.16.101.11"
PREFIX="16"
GATEWAY="172.16.0.254"
DNS1="172.20.1.4"
DNS2="180.76.76.76"
BONDING_OPTS="mode=1 miimon=100 primary=eth1"

4、加载bond0接口到内核

vi /etc/modprobe.d/bonding.conf

修改成如下:

alias bond0 bonding

5、编辑eth0、eth1的接口文件

# vi /etc/sysconfig/network-scripts/ifcfg-eth0 
DEVICE="eth0"
BOOTPROTO="none"
HWADDR="52:54:00:56:28:68"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="49d231f8-c5c4-40cd-8ebb-2c0b2d7a7864"
USERCTL=no
MASTER=bond0
SLAVE=yes

# vi /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
MASTER=bond0
SLAVE=yes
USERCTL=no
ONBOOT=yes
BOOTPROTO=none

6、加载模块、重启网络与测试

# modprobe bonding
# service network restart

查看bondo接口的状态

# cat /proc/net/bonding/bond0
