Seata 2.0实战

  • 前期准备

    • 已安装 MySQL
    • 已安装 Docker
    • 已安装 Nacos

 

  • 安装Seata

为了方便，采用docker部署。国内的小伙伴可以配置以下镜像源：

  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "experimental": false,
  "features": {
    "buildkit": true
  },
  "registry-mirrors": [
    "https://docker.1ms.run",
    "https://docker.xuanyuan.me",
    "https://hub.rat.dev",
    "https://dockerproxy.com"
  ]
}

 

拉取镜像：

1
docker pull seataio/seata-server:2.0.0

 

拷贝资源文件夹到本机：

# 先运行镜像
docker run -d --name seata-server -p 8091:8091 seataio/seata-server:2.0.0
 
# 拷贝资源文件夹
docker cp seata-server:/seata-server/resources /root/docker/cloud/seata
 
# 删除容器
docker stop seata-server && docker rm seata-server

 

修改配置文件：/root/docker/cloud/seata/application.yml
