Centos7双网卡绑定

1.关闭NetworkManager服务

systemctl stop NetworkManager systemctl disable NetworkManager

2.加载bond模块

modprobe bonding miimon=100 mode=6 echo "alias bond0 bonding" >>/etc/modprobe.d/bond.conf echo "options bond0 miimon=100 mode=6" >> /etc/modprobe.d/bond.conf

3.配置网卡文件，以网卡em1、em2做端口聚合为例

创建网卡bond0的配置文件

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

# 添加以下配置，IP地址、掩码、网关按实际填写

DEVICE=bond0
