seata-server启动 ​

4.0 版本开始，DATASOURCE模式的(acuity-cloud-pro-datasource-column项目)某些操作已经无法避免同时操作 acuity_defaults 库 和 acuity_base_{TenantId} ，所以为了保证分布式事务准确性，acuity-cloud-pro-datasource-column项目集成了Seata来保证分布式事务准确性，其他模式无需Seata。

  • 注意：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。

官方文档： https://seata.io/ ​

安装&启动： ​

  1. 官网 下载 1.4.2 版 或者去群文件下载 seata142.zip , 解压到 D:\developer\seata-server-1.4.2（群文件里面的配置已经调整过了） 。

    seata 版本一定要一致！！！

  2. 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;

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

  4. 修改安装包 D:\developer\seata-server-1.4.2\conf/registry.conf 文件内容:

    json
    registry {
  type = "nacos"
  nacos {
    application = "seata-server"
    serverAddr = "localhost:8848"            # nacos 地址
    group = "SEATA_GROUP"
    namespace = "3cca7d98-3b1c-44d3-90e5-86abaaf0048a"    # 命名空间不要和acuity-cloud项目使用的混淆了
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
}
config {
  type = "nacos"
  nacos {
    serverAddr = "localhost:8848"              # nacos 地址
    namespace = "3cca7d98-3b1c-44d3-90e5-86abaaf0048a"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
    dataId = "seataServer.properties"
  }
}
    registry {
  type = "nacos"
  nacos {
    application = "seata-server"
    serverAddr = "localhost:8848"            # nacos 地址
    group = "SEATA_GROUP"
    namespace = "3cca7d98-3b1c-44d3-90e5-86abaaf0048a"    # 命名空间不要和acuity-cloud项目使用的混淆了
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
}
config {
  type = "nacos"
  nacos {
    serverAddr = "localhost:8848"              # nacos 地址
    namespace = "3cca7d98-3b1c-44d3-90e5-86abaaf0048a"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
    dataId = "seataServer.properties"
  }
}

  5. 将 https://github.com/seata/seata/blob/develop/script/config-center/config.txt 文件下载下来，并调整config.txt文件中的参数：

    properties
     # seata service 信息
 service.vgroupMapping.acuity_cloud_seata_tx_group=default
 service.default.grouplist=127.0.0.1:8091

 # 数据库信息

 store.db.driverClassName=com.mysql.cj.jdbc.Driver
 store.db.url=jdbc:mysql://172.26.3.32:3306/acuity_seata?useUnicode=true&rewriteBatchedStatements=true
 store.db.user=root
 store.db.password=root

 # 修改序列化方式， 使seata支持LocalDateTime字段
 client.undo.logSerialization=protostuff
     # seata service 信息
 service.vgroupMapping.acuity_cloud_seata_tx_group=default
 service.default.grouplist=127.0.0.1:8091

 # 数据库信息
 store.db.dbType=mysql
 store.db.driverClassName=com.mysql.cj.jdbc.Driver
 store.db.url=jdbc:mysql://172.26.3.32:3306/acuity_seata?useUnicode=true&rewriteBatchedStatements=true
 store.db.user=root
 store.db.password=root

 # 修改序列化方式， 使seata支持LocalDateTime字段
 client.undo.logSerialization=protostuff

  6. 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

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

    注意正确填写 DataId 和 Group ！

  8. seataServer.properties 全部内容：

  9. 导入成功后，确定下命名空间： 3cca7d98-3b1c-44d3-90e5-86abaaf0048a 下是否有1个配置文件

  10. 启动seata-server：

    shell
    参数解释： 
-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
    参数解释： 
-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

  11. 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
