10、网卡绑定bond0的实现

在配置文件上实现：
[21:28:12 root@CentOS8 ~]#**cat /etc/sysconfig/network-scripts/ifcfg-bond0 **
NAME=bond0
TYPE=bond
DEVICE=bond0
BOOTPROTO=none
IPADDR=10.0.0.8
PREFIX=8
BONDING_OPTS="mode=1 miimon=100 fail_over_mac=1"

[21:29:06 root@CentOS8 ~]#cat /etc/sysconfig/network-scripts/ifcfg-eth0
NAME=eth0
DEVICE=eth0
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
ONBOOT=yes

[21:29:14 root@CentOS8 ~]#cat /etc/sysconfig/network-scripts/ifcfg-eth1
NAME=eth1
DEVICE=eth1
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
ONBOOT=yes

效果如下：
[21:29:38 root@CentOS8 ~]#**ifconfig **
