课程名称：Linux 高可用性集群 课程概述：本课程旨在帮助您理解高可用性集群，结合理论知识和实践经验，重点介绍Red Hat / CentOS企业高可用性集群中的Pacemaker和Corosync组件。课程中的实验室设计基于KVM环境，使学员能够获得实际操作经验。 课程内容： 1. 介绍 - 什么是集群及其类型？ - 服务器集群的优势 - 集群的概念和技术 - 资源与资源组 - 故障转移、隔离、共享存储、法定人数 - 集群架构 2. 实验室设置 - 使用KVM环境进行实验室搭建 - 配置基本集群 - 在KVM主机上配置隔离代理 - 故障处理和集群节点管理 - 启动和停止集群服务 - 启用和禁用集群服务 - 添加和删除集群节点 - 处理待命与非待命节点 - 法定人数操作 3. 实践实验 - 管理法定人数计算 - 集群设置开关（如wait_for_all和auto_tie_breaker） 4. 创建和配置高可用性资源 - 创建集群Apache服务 - 管理资源 - 故障排除高可用性集群 - 集群日志管理 - 故障处理资源故障和网络问题 - 复杂资源组的配置 - 管理约束条件（顺序、位置和共置约束） 5. 两节点集群问题实践 - 处理节点失败、脑瘫、隔离死亡问题 - 集群服务管理 6. iSCSI和存储管理 - iSCSI基础知识 - 配置iSCSI服务器与多种存储类型 - 创建块后端存储 - 管理高可用性逻辑卷 7. GFS2文件系统 - GFS2概念与创建管理 - 增长和修复GFS2文件系统 本课程不包含字幕，旨在通过深入的理论知识与丰富的实践经验，帮助学员掌握Linux高可用性集群的核心技能。
