1.3seata相关配置的修改

seata-server-1.7.0\seata\conf下的application.yml进行修改

server:
  port: 7091

spring:
  application:
    name: seata-server

logging:
  config: classpath:logback-spring.xml
  file:
    path: F:/2023_wyr_study/logs
  extend:
    logstash-appender:
      destination: 127.0.0.1:4560
    kafka-appender:
      bootstrap-servers: 127.0.0.1:9092
      topic: logback_to_logstash

console:
  user:
    username: seata
    password: seata
    ##此处为修改内容
    ########### 配置中心为nacos
seata:
  config:
    # support: nacos, consul, apollo, zk, etcd3 配置中心
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      group : "SEATA_GROUP"
      namespace: ""
      dataId: "seataServer.properties"
      username: "nacos"
      password: "nacos"
          ########### 注册中心为nacos
  registry:
    # support: nacos, eureka, redis, zk, consul, etcd3, sofa
    type:  nacos
    nacos:
      application: seata-server
      server-addr: 127.0.0.1:8848
      group : "SEATA_GROUP"
      namespace: ""
      username: "nacos"
      password: "nacos"
      ########### 存储模式为数据库且存到mysql 这里根据你自己的mysql连接版本写
      ######## 到seata-server-1.7.0\seata\lib\jdbc看是否支持
  store:
    # support: file 、 db 、 redis
    mode: db
    db:

1.4事务表的创建

数据库名为seata和上述配置文件中的数据库名称一致
sql语句位置seata-server-1.7.0\seata\script\server\db

启动你的nacos再启动你的seata就ok了
