本文主要是介绍CentOS 7.6 bond mode4 配置，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

CentOS 7.6 bond mode4 配置

双万兆网口配置 bond mode4 layer3+4

双网卡配置 bond mode4 配置

# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)

yum search ifconfig
yum install net-tools.x86_64

• 查看网线是否插入

# cat /sys/class/net/ens3f0/carrier
1
# cat /sys/class/net/ens3f1/carrier
1

• 关闭 NetworkManager 服务

systemctl status NetworkManager.service
systemctl stop NetworkManager.service
systemctl disable NetworkManager.service

• 内核加载 bonding

modprobe --first-time bonding

# lsmod | grep bonding
bonding               152656  0

创建配置文件 ifcfg-bond0

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

DEVICE=bond0
TYPE=Bond
IPADDR=192.168.2.11
NETMASK=255.255.255.0
GATEWAY=192.168.2.1
DNS1=114.114.114.114
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
BONDING_MASTER=yes
BONDING_OPTS="miimon=100 mode=4 xmit_hash_policy=layer3+4"

如果bond0接口已经配置，不再需要配置

vim /etc/modprobe.d/bond.conf
alias bond0 bonding
options bond0 miimon=100 mode=4 xmit_hash_policy=layer3+4

备份网卡配置文件

cd /etc/sysconfig/network-scripts
cp ifcfg-ens3f0 ifcfg-ens3f0_backup
cp ifcfg-ens3f1 ifcfg-ens3f1_backup

ens3f0

vim /etc/sysconfig/network-scripts/ifcfg-ens3f0

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

UUID=39aa32a1-acb3-4cd3-a806-be5c041a2310
DEVICE=ens3f0
ONBOOT=yes
MASTER=bond0
SLAVE=yes

ens3f1

vim /etc/sysconfig/network-scripts/ifcfg-ens3f1

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=ens3f1
UUID=4b5c8908-3e83-40b2-a9db-d0713135f4c2
DEVICE=ens3f1
ONBOOT=yes
MASTER=bond0
SLAVE=yes

• 重启网络服务

systemctl restart network

# ifconfig
bond0: flags=5187<UP,BROADCAST,RUNNING,MASTER,MULTICAST>  mtu 1500inet 192.168.2.11  netmask 255.255.255.0  broadcast 192.168.2.255
