创建库导入SQL

在/script/server/db下的dm.sql下导入即可。具体的SQL如下

-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data

在Nacos中创建seata的命名空间

这里不做演示

将配置修改导入Nacos

在/script/config-center下的config.txt

主要修改以下几个信息：

store.mode=db
store.lock.mode=db
store.session.mode=db

store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://127.0.0.1:3306/seata?useUnicode=true&rewriteBatchedStatements=true
store.db.user=mysql
store.db.password=mysql

在/script/config-center/nacos下终端输入就会插入到Nacos中

sh nacos-config.sh -h 127.0.0.1 -p 8848 -g SEATA_GROUP -t seata命名空间id -u nacos -w nacos

修改yml

在/conf下的application.yml

启动Seata

启动/bin里边的seata-server.bat即可

修改yml

在涉及到的多个服务方法的服务中修改yml
