【Seata微服务分布式事务】1. Seata服务端环境搭建

seata-serve安装包

下载seata-server包，我所有的是0.9.0版本

wget https://github.com/seata/seata/releases/download/v0.9.0/seata-server-0.9.0.tar.gz

链接:https://pan.baidu.com/s/1jlBwCEYM3hn7zQiSpwRijg 密码:56vm

官网0.9.0版本以后conf文件已经没有SQL文件

执行SQL脚本

数据库名称：seata

    datacenter = "DefaultDataCenter"
    cluster = "default"
    group = "SEATA_GROUP"
    addressWaitTime = "3000"
  }
  file {
    name = "file.conf"
  }
}

config节点：

config {
  #config修改点3个  其他不要动
  # file、nacos 、apollo、zk、consul、etcd3
  #修改点1
  type = "nacos"
  nacos {
    #修改点2
    serverAddr = "47.112.217.177:8847"

  }
  etcd3 {
    serverAddr = "http://localhost:2379"

初始化seata的nacos配置

conf目录执行：

sh nacos-config.sh 47.112.217.177

注意：如果你的nacos的端口不是默认的8848需要改一下nacos-config.sh

我的nacos是集群所以改了默认端口。nacos集群搭建：https://my.oschina.net/u/1046143/blog/3217779

result=`curl -X POST "http://$nacosIp:8847/nacos/v1/cs/configs?dataId=$key&group=SEATA_GROUP&content=$value"`

执行完登录nacos后台：

启动 seata-server服务

[root@iZwz9e2l6djknfngtgxfbnZ conf]# cd ../bin/
[root@iZwz9e2l6djknfngtgxfbnZ bin]# ls
seata-server.bat  seata-server.sh

执行：./seata-server.sh

如果部署在服务器使用：./seata-server.sh -h 47.112.217.177 启动，指定外网IP

后台启动：nohup ./seata-server.sh -h 47.112.217.177 >log.out 2>1 &

如果服务详情里面的IP是内网IP，但是客服端项目在我们本地启动那边就会访问不到
