pacemaker(直译：心脏起搏器)，是一个群集资源管理器。它实现最大可用性群集服务（亦称资源管理）的节点和资源级故障检测和恢复使用您的首选集群基础设施（OpenAIS的或Heaerbeat）提供的消息和成员能力。
它可以做乎任何规模的集群，并配备了一个强大的依赖模型，使管理员能够准确地表达群集资源之间的关系（包括顺序和位置）。几乎任何可以编写脚本，可以管理作为心脏起搏器集群的一部分。
我再次说明一下，pacemaker是个资源管理器，不是提供心跳信息的，因为它似乎是一个普遍的误解，也是值得的。pacemaker是一个延续的CRM（亦称Heartbeat V2资源管理器），最初是为心跳，但已经成为独立的项目。
大家都知道，Heartbeat 到了V3版本后，拆分为多个项目，其中pacemaker就是拆分出来的资源管理器。
Heartbeat 3.0拆分之后的组成部分：
Heartbeat：将原来的消息通信层独立为heartbeat项目，新的heartbeat只负责维护集群各节点的信息以及它们之前通信；
Cluster Glue：相当于一个中间层，它用来将heartbeat和pacemaker关联起来，主要包含2个部分，即为LRM和STONITH。
Resource Agent：用来控制服务启停，监控服务状态的脚本集合，这些脚本将被LRM调用从而实现各种资源启动、停止、监控等等。
Pacemaker : 也就是Cluster Resource Manager （简称CRM），用来管理整个HA的控制中心，客户端通过pacemaker来配置管理监控整个集群。
主机和应用程序级别的故障检测和恢复
几乎支持任何冗余配置
同时支持多种集群配置模式
配置策略处理法定人数损失（多台机器失败时）
支持应用启动/关机顺序
支持，必须/必须在同一台机器上运行的应用程序
支持多种模式的应用程序（如主/从）
可以测试任何故障或群集的群集状态
stonithd：心跳系统。
lrmd：本地资源管理守护进程。它提供了一个通用的接口支持的资源类型。直接调用资源代理（脚本）。
pengine：政策引擎。根据当前状态和配置集群计算的下一个状态。产生一个过渡图，包含行动和依赖关系的列表。
CIB：群集信息库。包含所有群集选项，节点，资源，他们彼此之间的关系和现状的定义。同步更新到所有群集节点。
CRMD：集群资源管理守护进程。主要是消息代理的PEngine和LRM，还选举一个领导者（DC）统筹活动（包括启动/停止资源）的集群。
OpenAIS：OpenAIS的消息和成员层。
Heartbeat：心跳消息层，OpenAIS的一种替代。
CCM：共识群集成员，心跳成员层。
CMAN是红帽RHCS套件的核心部分，CCS是CMAN集群配置系统，配置cluster.conf，而cluster.conf其实就是openais的配置文件，通过CCS映射到openais。
CIB使用XML表示集群的集群中的所有资源的配置和当前状态。CIB的内容会被自动在整个集群中同步，使用PEngine计算集群的理想状态，生成指令列表，然后输送到DC（指定协调员）。Pacemaker 集群中所有节点选举的DC节点作为主决策节点。如果当选DC节点宕机，它会在所有的节点上， 迅速建立一个新的DC。DC将PEngine生成的策略，传递给其他节点上的LRMd（本地资源管理守护程序）或CRMD通过集群消息传递基础结构。当集群中有节点宕机，PEngine重新计算的理想策略。在某些情况下，可能有必要关闭节点，以保护共享数据或完整的资源回收。为此，Pacemaker配备了stonithd设备。STONITH可以将其它节点“爆头”，通常是实现与远程电源开关。Pacemaker会将STONITH设备，配置为资源保存在CIB中，使他们可以更容易地监测资源失败或宕机。
