centos7.6
关闭NetworkManager服务
systemctl stop NetworkManager
systemctl disable NetworkManager
这里我测试的是bond0
编辑配置文件
[root@localhost network-scripts]# cat ifcfg-bond0
DEVICE=bond0
BOOTPROTO=none
ONBOOT=yes
IPADDR=98.51.181.52
NETMASK=255.255.255.224
GATEWAY=98.51.181.33
DNS1=8.8.8.8
[root@localhost network-scripts]# cat ifcfg-eth0
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eth0
DEVICE=eth0
ONBOOT=yes
IPV6_PRIVACY=no
MASTER=bond0
SLAVE=yes
[root@localhost network-scripts]# cat ifcfg-eth1
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eth
DEVICE=eth1
ONBOOT=yes
IPV6_PRIVACY=no
MASTER=bond0
SLAVE=yes
#加载模块
modprobe --first-time bonding
4,修改modprobe相关设定文件
[root@localhost ~]# vi /etc/modprobe.d/bonding.conf
alias bond0 binding
options bond0 miimon=100 mode=1
重启网卡
systemctl restart network
（测试中遇到多服务器重启后，bond消失，解决方法是开机启动中加载模块）
vi /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
#加载模块
modprobe --first-time bonding
systemctl restart network
