centos7配置多网卡bond

配置网卡1 vi /etc/sysconfig/network-scripts/ifcfg-eno16777736
TYPE=Ethernet
BOOTPROTO=none
USERCTL=no
DEVICE=eno16777736
ONBOOT=yes
MASTER=bond0
SLAVE=yes

配置网卡2 vi /etc/sysconfig/network-scripts/ifcfg-eno33554944
TYPE=Ethernet
BOOTPROTO=none
USERCTL=no
DEVICE=eno33554944
ONBOOT=yes
MASTER=bond0
SLAVE=yes

配置虚拟bond网卡 vi /etc/sysconfig/network-scripts/ifcfg-bond0
TYPE=Bond
BOOTPROTO=none
ONBOOT=yes
USERCTL=no
DEVICE=bond0
IPADDR=192.168.121.129
PREFIX=24
NM_CONTROLLED=no
BONDING_MASTER=yes

配置bonding驱动 vi /etc/modprobe.d/bond.conf
alias bond0 binding
options bond0 miimon=100 mode=1

centos7默认没有加bonding内核模板，加载方式modprobe --first-time bonding
查看是否加载成功 lsmod | grep bonding 或者 modinfo bonding

重启网络服务service network restart

可能会启动失败，bond0的状态不是UP, 查看/var/log/message可看到如下信息
Error: Connection activation failed: Master device bond0 unmanaged or not available for activation

需要禁用NetworkManager

systemctl stop NetworkManager.service

systemctl disable NetworkManager.service

启动network后的结果

cat /proc/net/bonding/bond0
