seata1.8，2.0 linux 安装和配置 + nacos + springboot（已踩坑版）

1.下载包 https://github.com/apache/incubator-seata/releases/download/v1.8.0/seata-server-1.8.0.tar.gz
2.下载seata需要的mysql表文件  https://github.com/apache/incubator-seata/tree/1.8.0/script/server/db
3.在数据库创建名为seata的库，UTF8  ，执行下载的mysql.sql
4.linux解压seata-server-1.8.0.tar.gz
tar -zxvf  seata-server-1.8.0.tar.gz
5.编辑/seata/conf/application.yml配置文件

6.刚刚的yaml配置去nacos获取配置文件，所以我们需要在nacos创建一个配置文件
7.注意data-id和 namespace 要一致

8.到这里就可以启动linux的seata了
cd /aaa/seata/bin
./seata-server.sh -h xx.xx.xx.89 -p 8091
启动带ip地址,不然注册到nacos的时候是内网的ip, 我们的springboot服务在外网注册到seata，所以默认不写ip注册不上

9.启动时内存低于4G可能会报错内存不足，我的是2核2G 所以需要配置一下 /aaa/seata/bin/seata-setup.sh

 

10。再重新启动，启动成功后在nacos注册中心会显示当前的seata的服务



 

11.最后在springboot项目引入依赖
        <!-- https://mvnrepository.com/artifact/io.seata/seata-spring-boot-starter -->
        <dependency>
            <groupId>io.seata</groupId>
            <artifactId>seata-spring-boot-starter</artifactId>
            <version>1.8.0</version>
        </dependency>

12.在yml里配置请求的路径

seata:
  enabled: true
  application-id: seata-server
  enable-auto-data-source-proxy: false
  # 事务组的名称，对应service.vgroupMapping.default_tx_group=xxx中配置的default_tx_group
  tx-service-group: default_tx_group
  service:
    vgroup-mapping:
      default_tx_group: default
    group-list:
      default: xx.xx.xx.89:8091  # 你的 Seata TC 服务器地址
    disable-global-transaction: false
  config:
    type: nacos
    nacos:
      namespace: xxxxxx-f4e7-442f-b100-a23c12cbc6bb
      server-addr: xx.xx.xx.90:8848
      username: nacos
      password: ^e9*
      group: SEATA_GROUP
      data-id: seataServer.properties
  registry:
    type: nacos
    nacos:
      application: seata-server # tc服务在nacos中的服务名称
      cluster: default
      server-addr: xx.xx.xx.90:8848
      group: SEATA_GROUP
      namespace: xxxxx-f4e7-442f-b100-a23c12cbc6bb
      username: nacos
      password: ^e9*
