Seata ​

Seata是一款开源的分布式事务解决方案，致力于在微服务架构下提供高性能和简单易用的分布式事务服务。

具体安装配置参见官网
Seata

提示

seata官方仅支持MySQL、Oracle、Postgresql，不支持SQL Server，所以导致天源云项目的DATASOURCE模式也不支持SQL Server，column和none模式不受影响。

安装步骤 ​

官网 或 视频软件下载下载 1.4.2 版 ​

提示

seata 版本一定要一致！高版本没有适配过，可能有坑。

创建数据库 ​

sql
CREATE DATABASE `acuity_seata` CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
CREATE DATABASE `acuity_seata` CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

向acuity_seata库 导入 script/server/db/mysql.sql ​

在naocs中新建命名空间 ​

  • 命名空间ID：3cca7d98-3b1c-44d3-90e5-86abaaf0048a
  • 命名空间名: acuity-seata
  • 描述: acuity-cloud 分布式事务

在新建的命名空间中新增配置： seataServer.properties， 将修改后的 config.txt 文件中的内容复制进来。 ​

导入成功后，确认命名空间： 3cca7d98-3b1c-44d3-90e5-86abaaf0048a 下是否有1个配置文件 ​

启动seata-server： ​

参数解释： ​

shell
-p 指定端口
-h 指定ip，  需要修改成`自己的ip ,切记，不能使用127.0.0.1 和localhost ！！！
-m db  存储到数据库
-m file 存储到文件

# linux 或 mac
sh bin/seata-server.sh -p 8091 -h 192.168.1.34 -m db -n 1

# window: 双击或者cmd下面执行：
bin/seata-server.bat -p 8091 -h 192.168.1.34 -m db -n 1
-p 指定端口
-h 指定ip，  需要修改成`自己的ip ,切记，不能使用127.0.0.1 和localhost ！！！
-m db  存储到数据库
-m file 存储到文件

# linux 或 mac
sh bin/seata-server.sh -p 8091 -h 192.168.1.34 -m db -n 1

# window: 双击或者cmd下面执行：
bin/seata-server.bat -p 8091 -h 192.168.1.34 -m db -n 1

验证是否启动成功：打开nacos， 【服务管理】 -> 【服务列表】 ->【acuity-seata】-> 有一个服务名为 server-server 的服务 即表示成功 ​
