手把手教你，docker安装seata

docker安装seata教程

都知道分布式事务n种处理方案，但是比较好用的属于seata这块，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。

• 对业务无侵入：即减少技术架构上的微服务化所带来的分布式事务问题对业务的侵入
• 高性能：减少分布式事务解决方案所带来的性能消耗

seata的几种术语：

• TC（Transaction Coordinator）：事务协调者。管理全局的分支事务的状态，用于全局性事务的提交和回滚。
• TM（Transaction Manager）：事务管理者。用于开启、提交或回滚事务。
• RM（Resource Manager）：资源管理器。用于分支事务上的资源管理，向 TC 注册分支事务，上报分支事务的状态，接收 TC 的命令来提交或者回滚分支事务。

1. 下载seata docker镜像

docker pull seataio/seata-server

2.启动docker镜像

docker run -d --name seata-server -p 8091:8091 seataio/seata-server

1. 拷贝docker seata启动后的镜像文件文件至/config/docker-data/seata下

cd ..

mkdir config/docker-data/seata

docker cp seata-server:/seata-server /docker-data/seata

4.修改配置文件application.yml 参考application.example.yml

5.停掉并清除旧容器

docker stop xxxx

docker rm xxxx

6.重新启动新容器

docker run -d --restart always --name seata-server -p 8091:8091 -v /config/docker-data/seata/seata-server -e SEATA_IP=[公网ip] -e SEATA_PORT=8091 seataio/seata-server

接下来就可以在项目中进行相关操作了，爽不爽
