linux 上 seata1.5.2 安装（nacos作为注册以及配置中心，mysql作为存储中心）

seata 分布式事务  下载地址： seata1.5.2

进入 cd /usr/local

执行 mkdir project

进入 cd project 目录

将下载下来的zip 放到 服务器 /usr/local/project 下

执行 unzip seata-server-1.5.2.zip

如果提示 找不到unzip      执行 npm install unzip

进入 cd seata

进入 cd conf

修改 application.yml：   vim application.yml    注意替换自己的 nacos 地址
