原创
分布式事务seata的部署与配置
1.下载
2.seata配置文件
进入解压目录下的config目录的application.yml文件，默认注册中心是nacos，所以，需要修改2处nacos的地址。一般默认即可
3.在nacos里配置文件
配置列表 -> 创建配置
Data Id 值与seata配置文件中配置的data-id值保持一致，一般默认seataServer.properties
Group值与seata配置文件中的group值保持一致，一般默认DEFAULT_GROUP
配置内容如下：

4.数据库表创建
在nacos里配置文件url对应的库名，并创建相应的表
MySQL表创建语句如下：
-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`
(
`xid` VARCHAR(128) NOT NULL,

`gmt_create` DATETIME,
`gmt_modified` DATETIME,
PRIMARY KEY (`xid`),

) ENGINE = InnoDB
DEFAULT CHARSET = utf8mb4;
-- the table to store BranchSession data

CREATE TABLE IF NOT EXISTS `distributed_lock`
