一，简介
为便于对源码进行调试分析，本篇将以seata官方案例AT模式为基础，逐步展示如何搭建seata本地源码环境。
本地环境版本信息：
SpringBoot2.2.2
Dubbo 2.7.5
Mybatis 3.4.2
Nacos 2.1.0
Seata 1.0.0
MySQL 8.0.29
二，环境配置与服务启动
本地环境主要涉及：注册中心Nacos，Seata-Server，Buiness-Server
1，Nacos本地源码启动
官网下载源码：
将下载的Nacos源码作为maven工程用IDEA打开，并进行编译，如图所示
编译完成之后，修改配置文件中的MySQL信息为本地信息：

创建MySQL表：

找到Nacos启动类，启动Nacos:
路径：console/src/main/java/com/alibaba/nacos/Nacos.java
启动成功之后，访问如下地址：

2，Seata Server本地源码启动
官网下载源码：github.com/apache/incu…
导入本地IDEA，编译之后修改相关配置：

按照源码中的数据库脚本添加数据库表相关信息：
全局事务会话信息由3块内容构成，全局事务-->分支事务-->全局锁，对应表global_table, branch_table, lock_table
配置文件路径：script\server\db\mysql.sql
Seata-Server启动类：
server\src\main\java\io\seata\server\ServerApplication.java
启动成功之后，在Nacos注册中心可以看到Seata-Server已经注册：
3，业务系统启动
整个业务逻辑由 3 个微服务提供支持：仓储服务：对给定的商品扣除仓储数量。订单服务：根据采购需求创建订单。帐户服务：从用户帐户中扣除余额。
官方业务案例架构图：
Seata官方案例下载：github.com/apache/incu…
创建数据库表：
SEATA AT 模式需要 UNDO_LOG 表：
-- for AT mode you must to init this sql for you business database. the seata server not need it.
CREATE TABLE IF NOT EXISTS `undo_log`
(
`branch_id` BIGINT NOT NULL COMMENT 'branch transaction id',
`xid` VARCHAR(128) NOT NULL COMMENT 'global transaction id',
`context` VARCHAR(128) NOT NULL COMMENT 'undo_log context,such as serialization',

`log_status` INT(11) NOT NULL COMMENT '0:normal status,1:defense status',
`log_created` DATETIME(6) NOT NULL COMMENT 'create datetime',

UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
) ENGINE = InnoDB
AUTO_INCREMENT = 1
DEFAULT CHARSET = utf8mb4 COMMENT ='AT transaction mode undo table';
创建业务数据表：
CREATE TABLE `t_account` (
`id` int NOT NULL AUTO_INCREMENT,
`user_id` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`amount` double(14,2) DEFAULT '0.00',

配置完成之后依次启动各个服务。
三，结果查看
上述步骤完成之后，就可以在Nacos注册中心，看到各个服务已经完成启动并注册到了注册中心。后续我将以该环境为基础，深入分析Seata的运行机制与代码实现，敬请期待。
