一、版本说明
二、建立Seata Server数据库（TC-带头大哥的数据库）
三、业务库建表
四、安装Seata-Server
4.1 虚拟机里新建一个/opt/seate/seata-server文件夹，在seate文件夹下新建一个docker-compose.yml 文件
4.2 运行容器
4.3 在nacos里配置seata的相关信息
4.4 启动
一、版本说明
https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E
二、建立Seata Server数据库（TC-带头大哥的数据库）
https://github.com/apache/incubator-seata/tree/v1.6.1/script/server/db
三、业务库建表
在订单业务数据库和库存业务数据库里分别添加下表
https://github.com/apache/incubator-seata/blob/v1.6.1/script/client/at/db/mysql.sql
-- for AT mode you must to init this sql for you business database. the seata server not need it.
CREATE TABLE IF NOT EXISTS `undo_log`
(`branch_id` BIGINT NOT NULL COMMENT 'branch transaction id',`xid` VARCHAR(128) NOT NULL COMMENT 'global transaction id',`context` VARCHAR(128) NOT NULL COMMENT 'undo_log context,such as serialization',`rollback_info` LONGBLOB NOT NULL COMMENT 'rollback info',`log_status` INT(11) NOT NULL COMMENT '0:normal status,1:defense status',`log_created` DATETIME(6) NOT NULL COMMENT 'create datetime',`log_modified` DATETIME(6) NOT NULL COMMENT 'modify datetime',UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
) ENGINE = InnoDBAUTO_INCREMENT = 1DEFAULT CHARSET = utf8mb4 COMMENT ='AT transaction mode undo table';
四、安装Seata-Server
参考https://seata.apache.org/zh-cn/docs/v1.6/ops/deploy-by-docker-compose/#nacos%E6%B3%A8%E5%86%8C%E4%B8%AD%E5%BF%83db%E5%AD%98%E5%82%A8
4.1 虚拟机里新建一个/opt/seate/seata-server文件夹，在seate文件夹下新建一个docker-compose.yml 文件
docker-compose.yml 文件如图所示。
version: "3.1"
services:seata-server:image: seataio/seata-server:1.6.1ports:- "7091:7091"- "8091:8091"environment:- STORE_MODE=db# 以SEATA_IP作为host注册seata server- SEATA_IP=192.168.11.82- SEATA_PORT=8091volumes:- "/usr/share/zoneinfo/Asia/Shanghai:/etc/localtime" #设置系统时区- "/usr/share/zoneinfo/Asia/Shanghai:/etc/timezone" #设置时区# 假设我们通过docker cp命令把资源文件拷贝到相对路径`./seata-server/resources`中# 如有问题，请阅读上面的[注意事项]以及[使用自定义配置文件]- "./seata-server/resources:/seata-server/resources"
4.2 运行容器
版本和配置文件保持一致
目的是找到 id
docker run -d --rm seataio/seata-server:1.6.1
拷贝文件
利用id拷贝文件（将容器里的文件拷贝到宿主机）
docker cp 07d0:/seata-server/resources /opt/seata/seata-server/resources
修改application.yml文件内容
application.yml

4.3 在nacos里配置seata的相关信息
只需修改数据库相关配置即可,数据库名和第二个大标题建的保持一致 seata_tc

1.先cd 到seata文件夹，再执行下面的命令
docker-compose up -d
去nacos里查看服务是否启动
访问 端口为7091
