[root@lcx01 network-scripts]# cat >ifcfg-eth0 <<EOF

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=none

USERCTL=no

MASTER=bind0

EOF

编辑eth1网卡

[root@lcx01 network-scripts]# cat >ifcfg-eth1 <<EOF

DEVICE=eth1

ONBOOT=yes

BOOTPROTO=none

USERCTL=no

MASTER=bind0

EOF

3.2编辑bind0网卡

[root@lcx01 network-scripts]# cat >ifcfg-bind0<<EOF

DEVICE=bind0
