Seata安装部署

目前是用的nacos 配置信息存储在mysql数据库中。

安装

项目docs目录下面的soft文件夹中有seata1.6.1文件夹,上传到服务器，解压target。

配置

1、在mysql数据库中新建 seata_db 数据库，并导入脚本 seata_db.sql(邮件附带)。

2、修改Seata配置文件 application.yml.

在Nacos中配置SeataServer的配置信息 data-id名称要和{seata_home}/conf/application.yml中的一致

在nacos的public命名空间加入 配置 seataServer-dev.properties 文件如下配置 需要修改数据库配置
