下载

source：源文件
binary：编译后的文件，用以配置、启动
注：这两个文件都要下载，后面会用到源文件里的一些配置

serve端用到的sql

https://github.com/seata/seata/blob/master/script/server/db/mysql.sql

client用到的sql

https://github.com/seata/seata/blob/master/script/client/at/db/mysql.sql

快速入门（AT模式）

https://seata.io/zh-cn/docs/overview/what-is-seata.html

stata-server

seata/seata-server-1.4.2/bin目录下

file.conf

修改mode = “db” 然后再修改db模块的配置信息(记得在seata库里初始化server端用到的sql)

registry.conf

根据自己nacos的配置进行修改

启动

nacos配置

https://seata.io/zh-cn/docs/user/configuration/nacos.html

配置seata-server端配置

创建命名空间seata_config

在命名空间seata_config中创建配置seataServer.properties的配置，类型为properties
配置内容参考
seata-1.4.2/script/config-center/config.txt（下载源文件里）记得修改
client.undo.logSerialization = "kryo"以及数据库配置

全局事务测试

nacos-client-server 调用 nacos-provider-server进行数据库写操作，发生异常然然后数据回滚
