centos6.x 配置bond

摘要: centos6.x下使用双网卡配置bond0, centos6 bond配置不需要在/etc/modprobe 中定义bond 直接在网卡中定义BONDING_OPTS 即可,例如bond0: BONDING_OPTS="mode=0 miimon=100"

物理网卡eth0 eth1绑定为bond0

1 物理网卡配置

ifcfg-eth0

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes

ifcfg-eth1

DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes

2 bond0网卡配置

ifcfg-bond0

DEVICE=bond0
ONBOOT=yes
BOOTPROTO=none
IPADDR=xx.xx.xx.xx
NETMASK=xx.xx.xx.xx
GATEWAY=xx.xx.xx.xx
DNS1=xx.xx.xx.xx
BONDING_OPTS="mode=0 miimon=100"

重启网卡

service network restart

3 查看bond0网卡状态

[root@localhost network-scripts]# cat /proc/net/bonding/bond0
