2.上传至云服务器，使用unar工具解压

3.配置application.yml，主要配置如下参数

  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: nacos
    nacos:
      server-addr: 
      namespace:

      max-wait: 5000

4.为seata执行mysql脚本

5.配置nacos配置中心

*6.启动seata服务器

../bin/seata-server.sh -h <真实ip>

问题：“cause:can not register RM,err:can not connect to services-server”

这个问题是因为在nacos里注册的网段是内网，而外部服务无法访问

*7.SpringBoot整合Seata

配置 yml：

seata:
  enabled: true
  #Seata 事务组编号，用于TC集群
  #要和 service.vgroupMapping.my_tx_group=default 中配置的相同
  tx-service-group: my_tx_group
  service:
    vgroup-mapping:
      my_tx_group: default
  ## 关闭自动代理
  enable-auto-data-source-proxy: false
  config: #配置中心，从nacos获取配置
    type: nacos
    nacos:

      username: 
      password: 

  registry: #TC服务注册中心的配置，微服务根据这些信息去注册中心获取tc服务地址

      group: SEATA_GROUP #seata组，与seata所在组保持一致
      username: 
      password:
  application-id: ${spring.application.name}

配置数据源代理：

@Configuration
public class DataSourceConfig {

    @Bean
    @Primary
    public DataSource dataSource(DataSourceProperties properties) {
        DataSource dataSource = properties.initializeDataSourceBuilder().build();
        return new DataSourceProxy(dataSource);
    }
}
