环境：
OS：Centos 6.3 x86_64
Keepalived:1.2.8
现象：使用killall -g 导致 master不能释放vip，slave偶尔能接管vip，偶尔不能接管vip；
最终强制去掉master vip：
ip addr del 192.168.1.249/32 dev eth0
man killall -g 的解释为： Kill the process group to which the process belongs. The kill signal is only sent once per group, even if multiple processes belonging to the same process group were found.

使用killall keepalived 能正常接管vip；
查看keepalived本身的 keepalived脚本：
是采用 killproc keepalived 这种方式结束掉keepalived进城的，
具体原因不知，在此仅作记录！
最后只能改用官方的脚本：
