前言
MHA（Master High Availability）是一种用于MySQL和MariaDB数据库的高可用解决方案。它是由一个主节点（Master）和多个从节点（Slave）组成的集群，当主节点故障时，自动切换到一个可用的从节点上，以确保数据库的连续性和可用性。
提示：以下是本篇文章正文内容，下面案例可供参考
一、概述
1.1 概念
MHA（MasterHigh Availability）是一套优秀的MySQL高可用环境下故障切换和主从复制的软件。
MHA 的出现就是解决MySQL 单点的问题。
MySQL故障切换过程中，MHA能做到0-30秒内自动完成故障切换操作。
MHA能在故障切换的过程中最大程度上保证数据的一致性，以达到真正意义上的高可用。
1.2 组成
MHA manager
管理节点
MHA node
数据节点
每个节点上都需要安装
1.3 特点
自动故障切换过程中，MHA试图从宕机的主服务器上保存二进制日志，最大程度的保证数据不丢失
使用半同步复制，可以大大降低数据丢失的风险，如果只有一个slave已经收到了最新的二进制日志，MHA可以将最新的二进制日志应用于其他所有的slave服务器上，因此可以保证所有节点的数据一致性
目前MHA支持一主多从架构，最少三台服务，即一主两从
1.4 工作原理
从宕机崩溃的master 保存二进制日志事件（binlog events）；
识别含有最新的更新slave日志
应用差异的中继日志（relay log）到其他的slave
应用从master保存的二进制日志事件
提升一个slave为新的master
使其他的slave连接新的master进行复制

启动时masterIP异常
需要工程手动配置VIP
2.3.4 测试
停用master的mariadb服务
master
slave1
2.3.5 故障恢复
修改app1.cnf启动配置
添加master主机配置信息
分别在slave上重新指定master主机及binlog日志同步信息
总结
总结来说，MHA是一种简单而有效的高可用解决方案，可以确保MySQL和MariaDB数据库在主节点故障时能够自动切换到可用的从节点上，从而保证数据库的连续性和可用性。
