Linux 系统双网卡绑定配置实现
系统版本
[root@~]#cat/etc/redhat-release CentOSrelease6.8(Final) [root@~]#uname-r 2.6.32-642.6.1.el6.x86_64
网卡说明
eth0 192.168.1.8（服务器外网卡）
eth1
eth2
两块服务器网卡(内网)
关闭防火墙
[root@~]#/etc/init.d/iptablesstop [root@~]#chkconfigiptablesoff
关闭selinux
[root@~]#setenforce0 [root@~]#sed-i‘s/SELINUX=enforcing/SELINUX=disabled/‘/etc/selinux/config
禁用NetworkManager
[root@~]#/etc/init.d/NetworkManagerstop StoppingNetworkManagerdaemon:[OK] [root@~]#chkconfigNetworkManageroff [root@~]#/etc/init.d/networkrestart
编辑eth1网卡
[root@~]#cd/etc/sysconfig/network-scripts/ [root@network-scripts\]#cat>ifcfg-eth1<编辑eth2网卡
[root@network-scripts]#cat>ifcfg-eth2<编辑bind0网卡
[root@network-scripts]#cat>ifcfg-bind0<配置bond参数
[root@network-scripts]#cat>/etc/modprobe.conf<加入开机自启动(/etc/rc.local)
[root@network-scripts]#cat>>/etc/rc.local<重启网络服务
