关闭 NetworkManager 服务
systemctl stop NetworkManager.service systemctl disable NetworkManager.service
配置网卡1
vim /etc/sysconfig/network-scripts/ifcfg-eno24 TYPE=Ethernet BOOTPROTO=none USERCTL=no DEVICE=eno24 ONBOOT=yes MASTER=bond0 SLAVE=yes
配置网卡2
vim /etc/sysconfig/network-scripts/ifcfg-eno25 TYPE=Ethernet BOOTPROTO=none USERCTL=no DEVICE=eno25 ONBOOT=yes MASTER=bond0 SLAVE=yes
配置bond
vim /etc/sysconfig/network-scripts/ifcfg-bond0 TYPE=Bond BOOTPROTO=none ONBOOT=yes USERCTL=no
NAME=bond0 DEVICE=bond0 IPADDR=192.168.1.4 PREFIX=24 GATEWAY=192.168.1.254 NM_CONTROLLED=no BONDING_MASTER=yes
BONDING_OPTS="mode=1 miimon=100"
加bonding内核模板
modprobe --first-time bonding lsmod | grep bonding 或者 modinfo bonding
配置bonding驱动
（实践该步骤未做，便可用） vim /etc/modprobe.d/bond.conf alias bond0 binding options bond0 miimon=100 mode=1
重启网络服务
service network restart
查看bond0生效
cat /proc/net/bonding/bond0
配置dns
vim /etc/resolv.conf nameserver 202.106.0.20
centos 7默认启动时没有加载bonding模块
# 查看bonding模块详细信息
modinfo bonding
filename /lib/modules/3.10.0-229.el7.x86_64/kernel/drivers/net/bonding/bonding.ko
# 配置系统启动时加载bonding模块
vim /etc/sysconfig/modules/bonding.modules
#!/bin/sh
/sbin/modinfo -F filename bonding > /dev/null 2>&1
if [ $? -eq 0 ];then
/sbin/modprobe bonding
fi
# 设置执行权限
chmod 755 /etc/sysconfig/modules/bonding.modules
# 重启查看是否生效
reboot
