Linux双网卡绑定解绑

双网卡教程

1. 停止NetworkManager

[[email protected] ~]# service NetworkManager stop
[[email protected] ~]# chkconfig NetworkManager off

2. 手工写绑定的配置 ifcfg-bond0

[[email protected] ~]#  vi /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
IPADDR=192.168.6.216
PREFIX=24
GATEWAY=192.168.6.1
USERCTL=no

[[email protected] ~]# mv /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0-bak #备份本文件
[[email protected] ~]#vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
slave=yes

[[email protected] ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
slave=yes

[[email protected] ~]# vi /etc/modprobe.d/bonding.conf

alias bond0 bonding
options bond0 miimon=100 mode=1

3. 开机生效

[[email protected] ~]# vi /etc/rc.d/rc.local

文档末尾增加内容

ifenslave bond0 eth0 eth1

4. 重启服务生效

[[email protected] ~]# service network restart-----远程连接断开（真实机器的话最好重启）
[[email protected] ~]# ifenslave bond0 eth0 eth1

5. 状态检查

[[email protected] ~]# ifconfig -a
[[email protected] ~]# cat /proc/net/bonding/bond0

6. 双网卡解绑

[[email protected] ~]# rm -rf /etc/sysconfig/network-scripts/ifcfg-bond0 
[[email protected] ~]# rm -rf /etc/modprobe.d/bonding.conf 

[[email protected] ~]# rm -rf /etc/sysconfig/network-scripts/ifcfg-eth0
[[email protected] ~]# rm -rf /etc/sysconfig/network-scripts/ifcfg-eth1

[[email protected] ~]# rmmod bonding
[[email protected] ~]# service network restart --远程连接断开
