事先需要准备好网络yum源，保证服务器可正常上网
关闭防火墙，关闭selinux
本次实验虚拟机环境下模拟，网卡为nat模式，dhcp分配ip，现添加两张网卡，如图

登录服务器后，由于是后添加的网卡，发现/etc/sysconfig/network-scripts下没有新加网卡的配置文件，然后使用以下命令
nmtui

改为对应网卡改为对应网卡名字

然后
cd /etc/sysconfig/network-scripts/
然后修改ifcfg-ens37,ifcfg-ens38配置文件（相当于末尾追加MASTER=bond0 SLAVE=yes，把BOOTPROTO改为none），如下
[root@localhost network-scripts]# cat ifcfg-ens37
HWADDR=00:0C:29:B2:F3:A9
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=ens37
UUID=f69a315d-2735-4489-b99e-7153f016e7b2
ONBOOT=yes
MASTER=bond0
SLAVE=yes
[root@localhost network-scripts]# cat ifcfg-ens38
HWADDR=00:0C:29:B2:F3:B3
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=ens38
UUID=3e20bf34-6f74-34ff-b702-7f0e74ed34bc
ONBOOT=yes
AUTOCONNECT_PRIORITY=-999
MASTER=bond0
SLAVE=yes
然后新加一个bond配置文件，这里选择mode 6，无需配置交换机
[root@localhost network-scripts]# cat ifcfg-bond0
TYPE=Bond
BOOTPROTO=dhcp
ONBOOT=yes
DEVICE=bond0
BONDING_MASTER=yes
BONDING_OPTS="mode=6 miimon=100"
然后重启网络
systemctl restart network
然后使用nmtui发现

[root@localhost network-scripts]# lsmod | grep bonding
bonding 152979 0
[root@localhost network-scripts]# cat /proc/net/bonding/bond0
