此时我们计算机里面就有两块网卡了，因为我们需要将这两块网卡绑定到bond0这个逻辑网卡中，所以我们要在两块网卡的配置文件里面添加两条语句：
MASTER=bond0 // 将这两块网卡绑定到bond0这块逻辑网卡上
SLAVE=yes // SLAVE=yes表示这两块网卡附属于bond0这块网卡
[root@xiaoluo network-scripts]# vi ifcfg-eth0 DEVICE=eth0 HWADDR=08:00:27:D7:F8:84 TYPE=Ethernet UUID=2877e96e-6ddd-443b-a337-bafa7c77c6e5 ONBOOT=no NM_CONTROLLED=yes BOOTPROTO=none IPV6INIT=no USERCTL=no MASTER=bond0 SLAVE=yes [root@xiaoluo network-scripts]# vi ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none TYPE=Ethernet PEERDNS=yes IPV6INIT=no ONBOOT=no USERCTL=no HWADDR=08:00:27:f4:7d:cc MASTER=bond0 SLAVE=yes
之前说过bond0这块网卡其实是通过一个叫做 bonding 的驱动来配置的，所以我们还需要为bond0这块网卡添加驱动支持，将这个驱动添加到 /etc/modprobe.d/ 这个目录下
[root@xiaoluo network-scripts]# cd /etc/modprobe.d/ [root@xiaoluo modprobe.d]# ls anaconda.conf blacklist-visor.conf dist.conf openfwwf.conf blacklist.conf dist-alsa.conf dist-oss.conf
这个文件夹下放的都是我们系统所需驱动的配置文件，我们这时需要给我们的bonding添加一个名字为 bonding.conf 的配置文件
[root@xiaoluo modprobe.d]# vi bonding.conf alias bond0 bonding
此时配置好以后，我们就可以通过 ifup bond0 来启动我们的bond0网卡
[root@xiaoluo network-scripts]# ifup bond0 Active connection state: activated Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/2
此时我们可以通过ifconfig命令来查看一下当前网卡信息：
[root@xiaoluo network-scripts]# ifconfig
