Centos6/7多網卡綁定配置
1. 關閉NetworkManager服務
systemctl stop NetworkManager
systemctl disable NetworkManager
2. 加載bond模塊
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. 配置網卡文件，以網卡eth0、eth1做綁定為例
創建網卡bond0的配置文件
vim /etc/sysconfig/network-scripts/ifcfg-bond0
# 添加以下配置，IP地址、掩碼、網關按實際填寫
DEVICE=bond0
BOOTPROTO=static
USERCTL=no
ONBOOT=yes
TYPE=Bond
BONDING_MASTER=yes
BONDING_OPTS="mode=0 miimon=100"
IPADDR=10.42.31.1
NETMASK=255.255.255.0
GATEWAY=10.42.31.1
#修改網卡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
#修改網卡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. 重啟網絡服務，確認網絡是網卡速率;
systemctl restart network
ethtool bond0
