[root@localhost ~]#service network restart

原因是没有加载bonding模块所致：

[root@localhost ~]#lsmod | grep bonding
[root@localhost ~]#
[root@localhost ~]#cd /etc/sysconfig/modules/
[root@localhost ~]#cat bonding.modules   ------ bonding模块文件，需创建
modprobe bonding mode=0 miimon=100
[root@localhost ~]#
[root@localhost ~]#modprobe bonding

查看模块是否加载成功：

[root@localhost ~]#lsmod | grep bonding
bonding               138201  0
ipv6                  435361  85 bonding
[root@localhost ~]#

最后，重启下network服务：

[root@localhost ~]#service network restart
Shutting down interface bond0:                              [  OK  ]
Shutting down interface eth5:                               [  OK  ]
Shutting down loopback interface:                           [  OK  ]
