在nacos新建配置文件seataServer.properties
官方供参考的配置文件: config.txt 以下为我修改后的配置文件

进入文件夹
/etc/systemd/system创建seata.service文件
#固定写法换一下路径即可
#!/bin/sh

WantedBymulti-user.target【注意】此处-h 后接当前主机IP如不接在nacos上注册的会显示为172开头的虚拟IP
设置开机自启并刷新配置
systemctl enable seata
systemctl daemon-reload # 刷新配置启动seata
systemctl start seata
systemctl status seata # 查看服务状态完成 打开浏览器ip:7091即可看到控制台。账号密码为前面修改配置文件设置的密码即seata。
微服务接入seata
pom中引入seata依赖

#Transaction routing rules configuration, only for the client
service.vgroupMapping.default_tx_groupdefault使用
主接口增加注解 GlobalTransactional远程调用服务增加注解 Transactional。项目接入多数据源新建两方法分别插入数据到不同库看回滚效果。
TIPS本项目使用的是mybatis-plus
