红帽全球峰会1.3. 集群和 Pacemaker 配置文件
红帽高可用性附加组件的配置文件是 corosync.conf 和 cib.xml。
-
corosync.conf文件提供了corosync所使用的集群参数，corosync 是构建 Pacemaker 的集群管理器。通常，您不应该直接编辑corosync.conf，而是使用pcs界面、HA Cluster Management RHEL web 控制台附加组件或ha_clusterRHEL 系统角色。 -
cib.xml文件是一个 XML 文件，代表集群配置和集群中所有资源的当前状态。Pacemaker 的集群信息基础（Cluster Information Base，CIB）会使用这个文件。CIB 的内容会在整个集群中自动保持同步。不要直接编辑cib.xml文件；使用pcs界面、HA Cluster Management RHEL web 控制台附加组件或ha_clusterRHEL 系统角色。
