配置網卡1
vim /etc/sysconfig/network-scripts/ifcfg-eno24 TYPE=Ethernet BOOTPROTO=none USERCTL=no DEVICE=eno24 ONBOOT=yes MASTER=bond0 SLAVE=yes
配置網卡2
vim /etc/sysconfig/network-scripts/ifcfg-eno25 TYPE=Ethernet BOOTPROTO=none USERCTL=no DEVICE=eno25 ONBOOT=yes MASTER=bond0 SLAVE=yes
配置bond
vim /etc/sysconfig/network-scripts/ifcfg-bond0 TYPE=Bond BOOTPROTO=none ONBOOT=yes USERCTL=no

BONDING_OPTS="mode=1 miimon=100"
加bonding內核模板
modprobe --first-time bonding lsmod | grep bonding 或者 modinfo bonding
配置bonding驅動
（實踐該步驟未做，便可用） vim /etc/modprobe.d/bond.conf alias bond0 binding options bond0 miimon=100 mode=1
重啟網絡服務
service network restart
查看bond0生效
cat /proc/net/bonding/bond0
配置dns
vim /etc/resolv.conf nameserver 202.106.0.20
