Seata 是一款开源的分布式事务解决方案，致力于提供高性能和简单易用的分布式事务服务。Seata 将为用户提供了 AT、TCC、SAGA 和 XA 事务模式，为用户打造一站式的分布式解决方案。

安装

1. 运行镜像

docker run --name seata1.3.0 -p 8091:8091 -d  seataio/seata-server:1.3.0

2. 复制配置文件到主机

mkdir -p /home/dockerdata/seata1.3.0
docker cp seata1.3.0:/seata-server  /home/dockerdata/seata1.3.0

4. 停止服务

docker stop seata1.3.0

5. 删除docker容器

docker rm seata1.3.0

6. 重新运行服务，至此服务已经启动完成，接下来就是在/home/dockerdata/seata1.3.0/seata-server目录中修改对应的配置（设置开机自启和关键配置挂载到本地目录方便修改配置）

docker run -d --restart always  --name  seata1.3.0 -p 8091:8091  -v /home/dockerdata/seata1.3.0/seata-server:/seata-server -e SEATA_IP=10.176.11.128 -e SEATA_PORT=8091 seataio/seata-server:1.3.0

7.修改registry.conf文件，修为nacos启用方式,绿色字体为修改的关键地方

cd /home/dockerdata/seata1.3.0/seata-server/resources/
修改vi registry.conf
把type = "file"改为type = "nacos"
nacos注册修改

  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = ""
    password = ""
  }

改为

nacos {
    application = "seata-server"
    serverAddr = "10.176.11.128:8848"
    namespace = "00163087-1658-4298-93a9-5ba3112eb227"
    cluster = "default"
    username = ""
    password = ""
  }

nacos配置修改
type = "file"改为type = "nacos"

  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = ""
    group = "SEATA_GROUP"
    username = ""
    password = ""
  }

改为

nacos {
    serverAddr = "10.176.11.128:8848"
    namespace = "00163087-1658-4298-93a9-5ba3112eb227"
    group = "DEFAULT_GROUP"
    username = ""
    password = ""
  }

项目中的库需要执行，sql文件路径：https://github.com/seata/seata/tree/develop/script/client

seata服务需要sql https://github.com/seata/seata/tree/develop/script/server

不用的模式执行不同的脚本

具体的注意点查看/home/dockerdata/seata1.3.0/resources/README-zh.md

8. 创建数据库

新建Seata数据库

9. 修改file.conf存储方式为mysql

vi file.conf 把mode = "file"改为mode = "db"
数据库配置修改

    url = "jdbc:mysql://127.0.0.1:3306/seata"
    user = "mysql"
    password = "mysql"

改为

    url = "jdbc:mysql://10.176.11.128:3306/seata?useUnicode=true&characterEncoding=utf8&autoReconnect=true&useSSL=false&serverTimezone=Asia/Shanghai"
    user = "root"
    password = "root"

10.重启服务

docker restart seata1.3.0
docker logs seata1.3.0  #查看启动日志
