前提配置

目录结构

• 创建seata 文件夹

	mkdir seata

• 编写config.txt 内容如下

service.vgroupMapping.${spring.application.name}-group=default
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://${host}:${port}/ry-seata?useUnicode=true
store.db.user=root
store.db.password=${pwd}
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000

• 编写registry.conf 内容如下

registry {
  type = "nacos"
  nacos {
    application = "seata-server"
    serverAddr = "${nacosHost:port}"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = "${nacosLoginName}"
    password = "${pwd}"
  }
}

config {
  type = "nacos"
  nacos {
    serverAddr = "${nacosHost:port}"
    namespace = ""
    group = "SEATA_GROUP"
    username = "${nacosLoginName}"
    password = "${pwd}"
  }
}

• 编写nacos-config.sh 内容如下
