1. 解压安装包到指定目录
$ tar xvf seata-server-1.4.2.tar.gz -C /data/seata/
#创建数据库跟seata需要的用户，导入seata自带的sql文件
数据库Sql文件在/seata-1.4.2/script/server/db/mysql.sql
#修改seata注册文件registry.conf，注册到nacos
vim registry.conf

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos "  #修改为nacos
 
  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
 
    #如果nacos开启了权限控制，请配置用户名密码
    username = "nacos"
    password = "****"
  }
}
 
config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"  #修改为nacos
 
  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = ""
    group = "SEATA_GROUP"
 
    #如果nacos开启了权限控制，请配置用户名密码
    username = "nacos"
    password = "****"
  }
}
#新建config.txt文件，修改数据库信息
$ vim /data/seata/config.txt

#执行nacos-config.sh脚本注册到nacos里面
sh nacos-config.sh

2. 启动seata
sh /data/seata/bin/seata-server.sh > seata.log &

#检查Nacos里面的服务列表是否有seata-server这个服务，有的话则注册成功
