Centos7部署Seata分布式事务系统并以nacos为配置中心

简介

Seata 是阿里巴巴开源的分布式事务中间件，一种分布式事务解决方案，具有高性能和易于使用的微服务架构

安装

下载安装包：https://github.com/seata/seata/releases

根据系统运行环境下载不同的压缩文件：

Mac/Linux下载seata-server-xxx.tar.gz；

Windows下载seata-server-xxx.zip。

通过工具（winSCP）将下载的的压缩包放到服务器指定目录下。

通过命令（tar -xvf ）解压压缩包：

Centos7部署Seata分布式事务系统并以nacos为配置中心

解压后会生成一个 seata目录，进入可以看到如下目录

然后进入 conf 目录

修改 registry.config文件：

将type 改为 nacos ，并配置nacos地址。

如下：

registry {
  type = "nacos"
  nacos {
    serverAddr = "111.231.111.150:8848"
    namespace = "public"
    cluster = "default"
  }
}
config {
  type = "nacos"
  nacos {
    serverAddr = "111.231.111.150:8848"
    namespace = "public"
  }
}

修改 nacos-config.txt 文件：

修改store.mode 存储模式为 db，默认file；

修改数据库链接信息：store.db.url、store.db.user、store.db.password；

其他默认即可。
