RHEL5下配置网卡绑定

1,/etc/sysconfig/network-scripts目录下生成如下三个文件
vi ifcfg-bond1
DEVICE=bond1
BOOTPROTO=static
IPADDR=10.4.124.*
NETMASK=255.255.255.224
GATEWAY=10.4.124.*
ONBOOT=YES
TYPE=Ethernet
USERCTL=no
BONDING_OPTS="miimon=100 mode=1"


vi ifcfg-eth4

DEVICE=eth4
BOOTPROTO=none
ONBOOT=yes
USERCTL=no
MASTER=bond1
SLAVE=yes

vi ifcfg-eth5

DEVICE=eth5
BOOTPROTO=none
ONBOOT=yes
USERCTL=no
MASTER=bond1
SLAVE=yes

2，修改modprobe.conf文件按，添加一行
vi /etc/modprobe.conf
alias bond1 bonding

3，重启网络

service network restart

4，查看网络的状态
