双网卡bond绑定

Posted 2020-12-13 lyonvip

1. 关闭NetworkManager服务

systemctl stop NetworkManager
systemctl disable NetworkManager

2. 加载bond模块

modprobe bonding miimon=100 mode=0
echo "alias bond0 bonding" >>/etc/modprobe.d/bond.conf
echo "options bond0 miimon=100 mode=0" >> /etc/modprobe.d/bond.conf

**3. 配置网卡文件，以网卡eth0、eth1做绑定为例 **
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
BOOTPROTO=static
USERCTL=no
ONBOOT=yes
TYPE=Bond
BONDING_MASTER=yes
BONDING_OPTS="mode=0 miimon=100"
IPADDR=13.50.1.122
NETMASK=255.255.255.0
GATEWAY=13.50.1.1

#修改网卡eth0的配置文件

vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
MASTER=bond0
SLAVE=yes

#修改网卡eth1的配置文件

vim /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE="eth1"
BOOTPROTO="none"
ONBOOT="yes"
USERCTL=no
MASTER=bond0
SLAVE=yes

4. 重启网络服务，确认网络是网卡速率

systemctl restart network
ethtool bond0
