linux bond配置步骤

一、网卡绑定

第一步：创建一个ifcfg-bondX

Bash

# vi /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
BONDING_OPTS="mode=0 miimon=100"
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.0.180
NETMASK=255.255.255.0
NETWORK=192.168.0.0
USERCTL=no

BONDING_OPTS="mode=0 miimon=100" ，mode有多种模式实现不同的功能

第二步：修改ifcfg-ethX

Bash

# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no

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

第三步：配置/etc/modprobe.conf，添加alias bond0 bonding

# vim /etc/modprobe.conf
alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptspi
alias scsi_hostadapter2 ata_piix
alias scsi_hostadapter3 ahci
alias net-pf-10 off
alias ipv6 off
options ipv6 disable=1
alias eth0 b0                # 后面分组的名字，eth0 和 eth3 对应的是bond0
alias eth1 b1
alias eth2 e1000
alias eth3 b0
alias eth4 b1
alias bond0 bonding
alias bond1 bonding
options bond0 miimon=100 mode=1 primary=eth0
options bond1 miimon=100 mode=1 primary=eth1
options bonding max_bonds=2 miimon=200 mode=1

第四步：重启网络服务

service network restart

通过查看/proc/net/bonding/bond0，查看当前是用什么mode，如果是主备的话，当前是哪个网卡工作。
