根据这里的版本说明我们选择seata1.6.1版本
https://github.com/seata/seata/tree/master/script
服务器
我们装备一个seata数据库
https://github.com/seata/seata/blob/master/script/server/db/mysql.sql
客户端
https://github.com/seata/seata/blob/master/script/client/at/db/mysql.sql
【修改配置】
复制application.example.yaml的部分内容到application.yaml
我们使用的是nacos，所以复制这块过来

【启动server】
windows：
seata-server.bat启动后nacos就能看到一个seata-server的服务
https://github.com/seata/seata/blob/master/script/config-center/config.txt
复制这里的内容，写入到nacos，名为seataServer.properties
