雙網(wǎng)卡綁定配置過程
[root@ ~]# cd /etc/sysconfig/network-scripts/
編輯eth1網(wǎng)卡
[root@ network-scripts]# cat >ifcfg-eth1 <> DEVICE=eth1
> ONBOOT=yes
> BOOTPROTO=none
> USERCTL=no
> MASTER=bind0
> EOF
編輯eth2網(wǎng)卡
[root@ network-scripts]# cat >ifcfg-eth2
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
MASTER=bind0
EOF
編輯bind0網(wǎng)卡
[root@ network-scripts]# cat >ifcfg-bind0 <> DEVICE=bind0
> TYPE=Ethernet
> ONBOOT=yes
> BOOTPROTO=none
> IPADDR=10.0.0.8
> NETMASK=255.255.255.0
> GATEWAY=10.0.0.254

配置bond參數(shù)
[root@ network-scripts]# cat >/etc/modprobe.conf <> alias bind0 bonding
> options bind0 miimon=100 mode=6
> EOF
加入開機(jī)自啟動(/etc/rc.local)
[root@ network-scripts]# cat >>/etc/rc.local <> ifenslave bind0 eth1 eth2
