还有user、password。

配置中心

dataId：通过dataId配置

1. 从v1.4.2版本开始，已支持从一个Nacos dataId中获取所有配置信息,你只需要额外添加一个dataId配置项。
2. 首先你需要在nacos新建配置，此处dataId为seataServer.properties,配置内容参考https://github.com/seata/seata/tree/develop/script/config-center 的config.txt并按需修改保存
3. 在client参考如下配置进行修改,

seata:
 config:
   type: nacos
   nacos:
     server-addr: 127.0.0.1:8848
     group : "SEATA_GROUP"
     namespace: ""
     dataId: "seataServer.properties"
     username: "nacos"
     password: "nacos"

通过脚本上传配置到Nacos
参考https://github.com/seata/seata/tree/develop/script/config-center 的config.txt并修改,之后运行仓库中提供的nacos脚本,将信息提交到nacos控制台,如果有需要更改,可直接通过控制台更改.
eg: sh ${SEATAPATH}/script/config-center/nacos/nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP -t 5a3c7d6c-f497-4d68-a71a-2e5e3340b3ca -u username -w password

下载 nacos-config.脚本 和 config.txt，

• nacos-config.脚本：https://github.com/seata/seata/blob/develop/script/config-center/nacos/nacos-config.sh
• config.txt：https://github.com/seata/seata/blob/develop/script/config-center/config.txt

打开 git bash 或 Linux 类命令，执行sh脚本

# -h 主机，你可以使用localhost，-p 端口号 你可以使用8848， -t 命名空间ID， -u 用户名， -p 密码
sh nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP -t .... -u nacos -nacos

配置到nacos。成功！

但是，配置实在太多了，找一个参数，闹大心。
所以用 dataId="seataServer.properties"。

ok了。
