开源项目之seata部署配置 seata1.5.2版本 我使用的nacos的

今天大哥给我一个任务是把seata部署到测试服务器上，1.5.2版本,踩了一些坑记录一下

一下是一些注意事项，最好提前完成

1.首先确保防火墙开启了seata的端口,两个端口号 一个是seata的web控制页面端口7091(默认),一个是seata-server监听的服务端口8091(默认),不使用控制台可以不开放7091，但是一定开放seata服务端口

2.确认能够连接上服务器，我使用的是nacos作为注册和配置中心 

3.如果是在云服务器上搭建记得配置安全组规则

正式部署

seata github下载地址

下载有两种 一种是启动器，直接命令启动 一种是源码 这里是启动器的部署

目录结构为

script > config-center 下的都是一些初始化配置命令 这里不建议初始化 我使用nacos初始化配置 给我在配置中心新建许多 ，一条一个 这里放置一个总配置文件 粘贴可用

主要配置

seata:
  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: nacos
    nacos:
      server-addr: nacos-ip
      #命名空间 不写则默认
      namespace: 
      #分组 不写则默认
      group: 
      username: nacos
      password: nacos
      # nacos 的配置文件名 需要和本身服务在一个分组（上面已经配过）
      data-id: seataServer.properties 
    registry:
    # support: nacos, eureka, redis, zk, consul, etcd3, sofa
    type: nacos
    nacos:
      application: seata-server
      server-addr: nacos-ip
      group: SEATA_GROUP
      namespace: 62be3490-1c58-4ba6-ad02-cee35574497b
      cluster: default
      username: nacos
      password: nacos
  store:
    # support: file 、 db 、 redis
    mode: db
    db:
      datasource: druid
      db-type: mysql
      driver-class-name: com.mysql.jdbc.Driver
      url: jdbc:mysql://mysql:3306/seata?rewriteBatchedStatements=true
      user: root
      password: root

script > server > db

中有相应的数据库文件 需要导入到一个数据库或单独的数据库中 

需要注意的是 （微服务所涉及的数据库如果用到分布式事务，需要在涉及的数据库中添加undo_log表来支持seata）

到这里基本就完成了

只需要在bin目录下启动一下

sh seata-server.sh -h 你的ip -p 8091 -m db

就可以了

剩下在微服务中进行seata的配置来连接默认是at模式
