一.Bonding的模式
1.balance-rr：轮询模式
2.active-backup：热备模式
3.broadcast：广播模式
二.配置步骤（命令配置）
1. 创建主接口
nmcli con add type bond con-name bond0 ifname bond0 mode active-backup
2. 给主接口分配ip地址
nmcli con mod bond0 ipv4.addresses ‘192.168.0.100/24‘
nmcli con mod bond0 ipv4.method manual
3. 创建从接口
nmcli con add type bond-slave ifname eno1 master bond0
nmcli con add type bond-slave ifname eno2 master bond0
4. 开启主接口和从接口
nmcli con up bond-slave-eno2
nmcli con up bond-slave-eno1
nmcli con up bond0
配置步骤（文件配置）
vi /etc/sysconfig/network-scripts/ifcfg-master
DEVICE=bond0
TYPE=Bond
BONDING_MASTER=yes
ONBOOT=yes
USERCTL=no
BONDING_OPTS="mode=balance-rr miimon=50"
BOOTPROTO=none
IPADDR0=10.1.1.250
PREFIX0=24
vi /etc/sysconfig/network-scripts/ifcfg-slave
DEVICE=<name>
TYPE=Ethernet
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no
三.查看结果
cat /proc/net/bonding/bond0
