seata2.0 下载安装部署，使用nacos为配置中心、注册中心

目录

1、nacos新建配置

2、下载seata安装包​​​​​​​

3、修改seata配置文件

4、启动seata server

1、nacos新建配置

请确保后台已经启动 Nacos 服务。

首先你需要在nacos新建配置，此处dataId为seataServer.properties

​​​​​​​配置内容参考（主要是中文备注的部分修改）

2、​​​​​​​​​​​​​​下载seata安装包

3、修改seata配置文件

配置文件seata/conf/application.yml，加入对应的配置中心

(主要是seata部分，用中文备注的配置）

4、启动seata server

切换到seata的bin目录，输入命令：./seata-server.sh

 可以看到提示已经启动成功，也可以到提示的日志目录查看日志文件，也可以输入http://localhost:7091

另外在nacos也可以看到seata-server注册成功
