The DEB and RPM packages include a service unit for Linux systems with systemd. On these systems, you can manage Heartbeat by using the usual systemd commands.

Setting Up A High-Availability Load Balancer (With Setting Up A High-Availability Load Balancer (With Failover and Session Support) With HAProxy/Heartbeat On Debian Lenny . Version 1.0 Author: Falko Timme Follow me on Twitter. This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Debian Lenny. The load balancer sits between What is the best way to implement a heartbeat in C++ to Yes, this heartbeat is the best way. You'll have to build it into the protocol the server and client use to communicate. The simplest solution is to have the client send data periodically and the server close the connection if it hasn't received any data from the client in a particular period of time. ocf_heartbeat_sfex(7) - Linux man page ocf_heartbeat_sfex - Manages exclusive access to shared storage using Shared Disk File EXclusiveness (SF-EX) Synopsis.

heartbeat was initially developed by Alan Robertson. Later SuSE got into as well (Lars Morowski). It started as a simple two-node-cluster with ASCII-configuration files (v1-syntax) and developed into a complex cluster with xml-configuration (v2).

Linux-HA - Wikipedia The Linux-HA (High-Availability Linux) project provides a high-availability solution for Linux, FreeBSD, OpenBSD, Solaris and Mac OS X which promotes reliability, availability, and serviceability (RAS).. The project's main software product is Heartbeat, a GPL-licensed portable cluster management program for high-availability clustering.Its most important features are: heartbeat(8) - Linux man page heartbeat is a basic heartbeat subsystem for Linux-HA. It will run scripts at initialisation, and when machines go up or down. This version will also perform IP address takeover using gratuitous ARPs. It works correctly for a 2-node configuration, and is extensible to larger configurations.
