第一章 KubeSphere + seata 1.5.2 + Nacos 2.1.0 （集群模式）

前言

Seata是一款开源的分布式事务解决方案组件，致力于提供高性能和简单易用的分布式事务服务。
Seata 将为用户提供了 AT、TCC、SAGA 和 XA 事务模式，为用户打造一站式的分布式解决方案（官方原话）。官方文档地址：https://seata.io/zh-cn/docs/overview/what-is-seata.html。本节内容我使用kubesphere 3.3.0 平台构建 seata 1.5.2 注册到nacos 2.1.0（集群模式）配置中心，数据库采用mysql8+。

---

一、创建Seata服务相关的数据库及相关表

提示：1.5.1不支持mysql8 从1.5.2开始支持mysql8
Seata服务数据存储的数据库和相关表脚本如下
seata参考地址：https://github.com/seata/seata/blob/develop/script/server/db/mysql.sql
nacos sql 地址：https://github.com/alibaba/nacos/blob/develop/distribution/conf/nacos-mysql.sql

-- -------------------------------- The script used when storeMode is 'db' --------------------------------

二、配置文件准备

2.1、application.yml 配置文件

server:
  port: 7091

spring:
  application:
    name: seata-server
  cloud:
    nacos:
      discovery:
        # 服务注册地址
        server-addr: jzb-nacos.jianzhubao:8848
      config:
        server-addr: jzb-nacos.jianzhubao:8848

logging:
  config: classpath:logback-spring.xml
  file:
    path: ${user.home}/logs/seata
#  extend:
#    logstash-appender:
#      destination: 127.0.0.1:4560
#    kafka-appender:
#      bootstrap-servers: 127.0.0.1:9092
#      topic: logback_to_logstash

console:
  user:
    username: seata
    password: seata

seata:
  config:
    # support: nacos 、 consul 、 apollo 、 zk  、 etcd3
    type: nacos
    nacos:
      # nacos ip地址
      server-addr: jzb-nacos.jianzhubao:8848
      group: DEFAULT_GROUP
      namespace: 
      username: "nacos"
      password: "nacos"
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
      # 读取nacos上的配置文件
      data-id: seata-server.properties
  registry:
    # support: nacos 、 eureka 、 redis 、 zk  、 consul 、 etcd3 、 sofa
    type: nacos
    nacos:
      application: seata-server
      # nacos ip地址
      server-addr: jzb-nacos.jianzhubao:8848
      group: DEFAULT_GROUP
      namespace: 
      cluster: default
      username: "nacos"
      password: "nacos"
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
  security:
    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
    tokenValidityInMilliseconds: 1800000
    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

提示：nacos集群，seata高版本注册失败：提示：以下是本篇文章正文内容，下面案例可供参考，加上以下配置解决问题：

spring:
  cloud:
    nacos:
      discovery:
        # 服务注册地址
        server-addr: jzb-nacos.jianzhubao:8848
      config:
        server-addr: jzb-nacos.jianzhubao:8848

2.2、 在kubesphere上创建seata-conf 配置文件

2.3、在naocs配置中心配置seata-server.properties文件

2.3.1、 seata-server.properties文件

2.3.2、 nacos配置

1、

2、创建后保存即可

3、

三、kubesphere 创建seata服务

3.1、创建服务

3.1.1 创建有状态服务器

3.1.2 基本信息

3.1.3 此处可以选择多个副本

提示：seata版本采用的是1.5.2（seataio/seata-server:1.5.2）
点击下一步继续

3.1.4 挂载我们提前准备好的配置文件

提示：挂载路径为 /seata-server/resources

3.1.5 创建

3.1.6 Seata启动成功

3.1.7 Seata注册成功

将nacos版本 从2.0.3升级到了2.1.0，spring-cloud-alibaba版本详情可参考：

https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E

四 总结

至此，关于使用KubeSphere管理平台搭建一个高可用的分布式事务服务组件Seata到这里就结束了（本文nacos为集群模式）。作者制作不易，别忘了点赞、关注、加收藏哦，我们下期见。。。
