环境:CentOS5.3 Linux version 2.6.18-128.el5,双网卡
配置:
1.编辑/etc/modprobe.conf 文件
#vi /etc/modprobe.conf加入如下内容
alias bond0 bonding
options bond0 miimon=100 mode=0
2.新建 bond0 文件
#cd /etc/sysconfig/network-scripts
#cp ifcfg-eth0 ifcfg-eth0_backup ---(备份要修改的文件)
#cp ifcfg-eth0 ifcfg-bond0
#vi ifcfg-bond0
DEVICE=bond0 ---(将eth0改为bond0)
IPADDR=192.168.0.231
GATEWAY=192.168.0.1
NETMASK=255.255.255.0
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
3.修改 eth0 文件,只保留必须的选项
#vi ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no
修改 eth1 的文件,同 eth0,只保留必须的选项
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no
4.修改/etc/rc.local这个文件,在内容最后添加如下一行:
#ifenslave bond0 eth0 eth1
5.测试结果,重启服务,建议重新启动计算机
#service network restart
#ifconfig 显示结果如下

环境:CentOS6.0 Linux version 2.6.32-71.el6.x86_64,双网卡
配置:
1.新建 bonding.conf 文件
#cd /etc/modprobe.d
#vi bonding.conf 加入如下内容
alias bond0 bonding
2.新建 bond0 文件
#cd /etc/sysconfig/network-scripts
#cp ifcfg-eth0 ifcfg-eth0_backup ---(备份要修改的文件)
#cp ifcfg-eth0 ifcfg-bond0
#vi ifcfg-bond0
DEVICE=bond0 ---(将eth0改为bond0)
IPADDR=192.168.0.231
GATEWAY=192.168.0.1
NETMASK=255.255.255.0
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
BONDING_OPTS="miimon=100 mode=0"
说明:miimon是用来进行链路监测的。 比如:miimon=100,那么系统每100ms监测一次链路连接状态,如果有一条线路不通就转入另一条线路;mode的值表示工作模式,他共有0,1,2,3四种模式,常用的为0,1两种。
mode=0表示load balancing (round-robin)为负载均衡方式,两块网卡都工作。
mode=1表示fault-tolerance (active-backup)提供冗余功能,工作方式是主备的工作方式,也就是说默认情况下只有一块网卡工作,另一块做备份.
bonding只能提供链路监测,即从主机到交换机的链路是否接通。如果只是交换机对外的链路down掉了,而交换机本身并没有故障,那么bonding会认为链路没有问题而继续使用
3.修改 eth0 文件,只保留必须的选项
#vi ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes

PS:重启服务器可能会出现网卡找不到的情况,这是因为centos6.0开始通过udev来管理网卡,具体网卡序号的配置文件在:/etc/udev/rules.d/70-persistent-net.rules文件中,解决办法
#vi /etc/udev/rules.d/70-persistent-net.rules
注释掉bond0的配置,再重启服务器就可以了
