安装集群

Seata的高可用依赖于注册中心、配置中心和数据库来实现；因此我们需要修改相关的配置。下面我们以nacos和MySQL为例子，Seata-Server使用注册中心进行集群间的通信，同时将事务数据保存到数据库中让整个集群统一使用事务信息。

修改配置文件

将 /work/seata/conf/application.example.yml 复制一份，重命名为 application.yml，修改配置

Server端存储模式（store.mode）现有file、db、redis三种（后续将引入raft,mongodb），file模式无需改动，直接启动即可，下面专门讲下db和redis启动步骤。

注：

  • file模式为单机模式，全局事务会话信息内存中读写并持久化本地文件root.data，性能较高;
  • db模式为高可用模式，全局事务会话信息通过db共享，相应性能差些;(mysql 5.7+)
  • redis模式Seata-Server 1.3及以上版本支持,性能较高,存在事务信息丢失风险,请提前配置合适当前场景的redis持久化配置

创建表和数据库

根据 /work/seata/script/server/db/mysql.sql 建数据库表seata

配置 seataServer

在nacos中新增配置 SEATA_GROUP seataServer.properties
