seata1.5.1安装（nacos作为注册以及配置中心，mysql8作为存储中心）
前面文章讲过SpringCloudAlibaba之Seata之文章，好多配置出现问题
seata下载地址： seata1.5.1
解压
安装到D盘，随便你辣

springcloudalibaba里配置
#分布式事务配置
seata:
application-id: ${spring.application.name}
enabled: true
enable-auto-data-source-proxy: true
#分组名称
tx-service-group: default_tx_group
#服务配置
service:
disable-global-transaction: false
vgroup-mapping:

grouplist:

#配置中心配置
config:
type: nacos
nacos:
application: seata-server
namespace: cloud-demo
serverAddr: localhost:8848
group: SEATA_GROUP
#注册中心配置
registry:
type: nacos
nacos:
application: seata-server
namespace: cloud-demo
server-addr: localhost:8848
group: SEATA_GROUP
service.vgroupMapping.default_tx_group，值为default。default_tx_group名称要与分布式事务配置tx-service-group的分组名称一致，其余如namespace，group也要一致，如果不新建这个文件，客户端启动，控制台会报错can not get cluster name in registry config ‘service.vgroupMapping.default_tx_group’, please make sure registry config correct
初始化数据库
新建数据库seata，字符集为utf8mb4
增加distributed_lock表用于seata-server异步任务调度 升级1.5.0前，请注意表结构变更，表结构详情请点击此处

更换mysql依赖包
由于seata1.5.1的mysql连接包是5.x版本的，连接mysql8时，会报错，所以依赖包需要替换为mysql-connector-java-8.0.27.jar
进入D:/seata-1.5.1/conf/target/seata-server.jar包，到BOOT-INF/lib目录下更换即可
启动
启动nacos后，再启动D:\seata-1.5.1\bin\seata-server.bat即可
