RedHat Linux 8.0环境中实现双网卡绑定指南

在RedHat Linux 8.0中实现双绑定指南

环境:          OS: redhat 8.0

1. #cd /etc/sysconfig/network-scripts

     # cp ifcfg-eth0    ifcfg-bond0

----------------------------------------------------------------

2 #vi ifcfg-bond0

      将第一行改成 DEVICE=bond0

----------------------------------------------------------------

3 # vi /etc/modules.conf

      加入两行

alias bond0 bonding

options bond0   miimon=100   mode=1

----------------------------------------------------------------

4 # vi /etc/rc.d/rc.local

      加入两行

    ifenslave bond0 eth0 eth1

      route add -net 192.168.0.0 netmask 255.255.255.0 bond0

----------------------------------------------------------------

5 reboot

重启会看见:

................

Bringing up interface bond0   [color=green:c8a84ac3e6]OK[/color:c8a84ac3e6]

Bringing up interface eth0     [color=green:c8a84ac3e6]OK[/color:c8a84ac3e6]

Bringing up interface bond1   [color=green:c8a84ac3e6]OK[/color:c8a84ac3e6]

----------------------------------------------------------------

6. 检查:

#netstat -r

192.168.0.0     255.255.255.0   0 40 0 0 bond0

192.168.0.0     255.255.255.0   0 40 0 0 eth0

192.168.0.0     255.255.255.0   0 40 0 0 eth1

这时候看看你的网卡后面的灯, 他们闪的频率是一样的.OK.

当#ifdown eth0 时, 转换有5-6秒的延时.

----------------------------------------------------------------

注意:

      如果网络不通需要重启bind

      # ifdown bind0

      #ifup       bind0

网卡绑定用在vncserver 或scp中就不灵了
