I'm using Keepalived to manage two Redis instances in a master/slave configuration. I'm experiencing a situation where, if Keepalived is terminated on the Master box (the one with the higher priority), the Backup server takes over as the master.
I run on Ubuntu and i want to use TCP keepalived in order to implement hearbeat between master-slave.both servers are my impl (c++).
I read this overview and did some google.
i didnt understand what TCP keepalived send and i do know if connection is no longer valid when use in TCP keepalive ?. Do i need to check the revived content?
