（1）执行sudo apt-get install ipvsadm。会提示 please run dpkg –reconfigure ipvsadm
（2）执行sudo dpkg–reconfigure ipvsadm，先是提示：
If you choose this option your IPVS rules will be loaded from /etc/ipvsadm.rules automatically on boot.
Do you want to automatically load IPVS rules on boot?
我选择的是NO。接着提示：
ipvsadm can activate the IPVS synchronization daemon. "master" starts this daemon in master mode, "backup" in backup mode and "both" uses master and backup mode at the same. "none" disables the daemon.
see the man page for more details,ipvsadm(8).
选择none。直接退出对话框，并提示ipvsadm is not configured to run. Please run dpkg–reconfigure ipvsadm.
照网上http://www.linuxidc.com/Linux/2010-07/27044.htm说的，接下来应该出现提示：
Select the multicast interface to be used by synchronization daemon.e.g. eth0,eth1...
这是为什么，我的操作出现什么问题了，求高手指点
