----------------------CentOS 6.5-------------------------------

1.添加bond内核模块

modprobe bonding   

2.添加四块网卡

3.编辑网卡进行配置

eth0:

vim  /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

ONBOOT=yes

TYPE=Ethernet

BOOTPROTO=static

USERCTL=no

MASTER=bond0

SLAVE=yes

eth1:

vim /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1

ONBOOT=yes

TYPE=Ethernet

BOOTPROTO=static

USERCTL=no

MASTER=bond0

SLAVE=yes

eth2:

vim /etc/sysconfig/network-scripts/ifcfg-eth2

DEVICE=eth2

ONBOOT=yes

TYPE=Ethernet

BOOTPROTO=static

USERCTL=no

MASTER=bond0

SLAVE=yes

eth3:

vim /etc/sysconfig/network-scripts/ifcfg-eth3

DEVICE=eth3

ONBOOT=yes

TYPE=Ethernet

BOOTPROTO=static

USERCTL=no

MASTER=bond0

SLAVE=yes

4.编辑bond虚拟主网卡

vim /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0

TYPE=Ethernet

ONBOOT=yes

BOOTPROTO=static

USERCTL=no

PEERDNS=yes

IPV6INIT=no

IPADDR=192.168.187.200

NETMASK=255.255.255.0

BROADCAST=192.168.187.255

GATEWAY=192.168.187.2

BONDING_OPTS="miimon=20 mode=6"    

//表示这里配置的工作模式是mode6(adaptive load balancing), miimon表示监视网络链接的频度 (毫秒), 我们设置的是100毫秒, 根据你的需求也可以指定mode成其它的负载模式。

 

5.创建一个加载bonding的专属设定文件/etc/modprobe.d/bonding.conf

echo "alias netdev-bond0 bonding" > /etc/modprobe.d/bonding.conf

cat /proc/net/bonding/bond0

ethtool bond0

6.重启系统

reboot

-------------------CentOS 7---------------------------------------------

nmcli connection add type bond ifname bond0 mode 6

nmcli connection add type bond-slave ifname ens33 master bond0

nmcli connection add type bond-slave ifname ens37 master bond0

nmcli connection add type bond-slave ifname ens38 master bond0

nmcli connection add type bond-slave ifname ens39 master bond0

systemctl restart network

cat /proc/net/bonding/bond0

ethtool bond0
