Debian Jessie Keepalived simple Redis Cluster

Even though keepalived under Debian Jessi give samples of check local service with killall in /usr/share/doc/keepalived/samples/keepalived.conf.vrrp.localcheck

But Jessie only have SystemD. [killall] has been remove with SystemV.
You can still use killall5 which is the SystemV killall command.

But killall5 simulates the killall command of SysV UNIX; it sends the given signal to all processes owned by the calling UID. When does it root, it can do very bad things. BE VERY CAREFUL with the killall command on!

# cat /etc/keepalived/keepalived.conf

In my opinion pidof is safer than killall or killall5.
