吐槽一下，官方文档是真少，而且更新很不及时。。
官网地址：直接部署 | Apache Seata
上述地址也包含了下载链接，我用的1.8版本，挑一些关键配置说一下

1、服务器上，seata/conf/application.yml，将seata.config和seata.registry都改为nacos相关信息

2、将nacos，seata-server中，新增store相关的配置，必须顶格，无需前缀。相关参数，全部为驼峰格式

3、库里需手动建表
seata/script/server/db目录下有对应库的sql语句，按需执行即可

4、代码附录

seata:
  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: nacos
    nacos:
      server-addr: 192.168.20.100:8848

      password: nacos
      context-path:
