这里使用的是seata-server-0.9.0

官网：http://seata.io/zh-cn/

首先分别将file.conf  、 registry.conf备份

接下来修改file.conf的部分内容

service部分

service {
    ##fsp_tx_group是自定义的
    vgroup_mapping.my.test.tx_group="fsp_tx_group" 
    default.grouplist = "127.0.0.1:8091"
    enableDegrade = false
    disable = false
    max.commitretry.timeout= "-1"
    max.ollbackretry.timeout= "-1"
}

store部分

## transaction log store
store {
	## store mode: file, db
	## 改成db
	mode = "db"
	
	## file store
	file {
		dir = "sessionStore"
		
		# branch session size, if exceeded first try compress lockkey, still exceeded throws exceptions
		max-branch-session-size = 16384
		# globe session size, if exceeded throws exceptions
		max-global-session-size = 512
		# file buffer size, if exceeded allocate new buffer
		file-write-buffer-cache-size = 16384
		# when recover batch read size
		session.reload.read_size= 100
		# async, sync
		flush-disk-mode = async
	}

	# database store
	db {
		## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc.
		datasource = "dbcp"
		## mysql/oracle/h2/oceanbase etc.
		## 配置数据源
		db-type = "mysql"
		driver-class-name = "com.mysql.jdbc.Driver"
		url = "jdbc:mysql://127.0.0.1:3306/seata"
		user = "root"
		password = "你自己密码"
		min-conn= 1
		max-conn = 3
		global.table = "global_table"
		branch.table = "branch_table"
		lock-table = "lock_table"
		query-limit = 100
	}
}

此处注意：！！！！

我使用的mysql版本是5.5，8.0以上版本驱动写法不一样

接着在mysql里新建一个seata库，导入sql脚本！！脚本在

然后修改 registry.conf

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  # 改用为nacos
  type = "nacos"

  nacos {
  	## 加端口号
    serverAddr = "localhost:8848"
    namespace = ""
    cluster = "default"
  }
  ...
}

在这里我们就配置完成了。

接着要先启动nacos！！！！再启动seata

 

还有一个小插曲，在启动seata的时候闪退了

原因是这里填写的nacos后面手多点了个空格

会出现这样的报错
