说明

• 环境准备：安装有docker环境的linux服务器
• 提示：建议docker配置国内加速镜像+nacos服务
• seata版本：2.0.0
• 如果你使用的是seata 2.0.0可以直接跳过 seata容器初步部署进入 seata使用nacos注册中心、db存储部分阅读

seata容器初步部署(可跳过)

• 这里给出seata容器初步部署的教程的目的是：避免不同seata版本的配置文件的差异，导致配置错误，进而seata应用无法正常运行。
• 建议使用和使用的seata兼容的配置文件，运行seta程序。

seata初部署

1. 编写/opt/1panel/apps/seata/docker-compose.yaml配置文件(这里的目录可以自定义，这里由于作者安装有1panel面板，为了方便统一管理容器所以放在此目录下)

version: "3"
services:
  seata-server:
    image: seataio/seata-server:latest
    hostname: seata-server
    container_name: seata
    ports:
      - "8091:8091"
      - "7091:7091"
    environment:
      - SEATA_PORT=8091
      - TZ=Asia/Shanghai

2. 启动seata容器

# 进入compose文件目录
cd /opt/1panel/apps/seata
# 部署seata
docker-compose up -d

获取配置文件

• 存放配置文件目录（可自定义），例如：/opt/1panel/apps/seata/data/conf/，同时获取

# 首先，获取Seata容器的ID或名称
docker ps
# 找到Seata容器的ID或名称后，运行以下命令将文件复制到容器外部
# <container_id>Seata容器的ID或名称
#<container_path> 要复制的文件路径
#<host_path>是要复制到的主机路径
docker cp <container_id>:<container_path> <host_path>
# 例如
docker cp seata:/seata-server/resources/application.yml /opt/1panel/apps/seata/data/conf/application.yml
docker cp seata:/seata-server/resources/application.example.yml /opt/1panel/apps/seata/data/conf/application.example.yml

• 获取到该容器下的配置文件信息后，可以参照example.yaml进行自定义配置

springboot简单集成seata测试

1. 添加maven依赖

   <dependency>
       <groupId>com.alibaba.cloud</groupId>
       <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
   </dependency>
   

2. 修改application.yaml配置事务组信息

# seata事务组配置
seata:
  tx-service-group: x-group # x-group可自定义名称注意和第四行中的组名称一致即可
  service:
    vgroup-mapping:
      x-group: default # 事务组和seata集群做关联
    grouplist:
      default: IP:8091 #seata集群对应的机器 IP使用服务器IP

3. 集成测试结果：启动项目，查看seata容器日志，显示如下

seata使用nacos注册中心、db存储

• 注意：此过程保证nacos全程开启
• seta官网 nacos注册中心，db存储指导

环境准备

准备nacos配置中心配置

• 首先在nacos中创建命名空间seata-server，然后再该命名空间下配置seataServer.yaml文件
  
  
• 设置Data ID为seataServer.yaml Group为SEATA_GROUP 配置格式设置为YAML 配置内容如下：
  

store:
    mode: db
    db:
      datasource: druid
      dbType: mysql
      driverClassName: com.mysql.cj.jdbc.Driver
      maxConn: 20
      maxWait: 5000
      minConn: 1
      user: xxx
      password: xxx
      url: jdbc:mysql://mysql_server_IP:3306/seata?useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false
      queryLimit: 100
      globalTable: global_table
      lockTable: lock_table
      branchTable: branch_table

• 最后，点击保存

准备Mysql数据库

• 创建数据库seata数据库名称可以自定义，注意和上一步的seataServer.yaml中的数据库名称保持一致即可。
• seata 2.0.0 使用nacos注册中心，db存储的数据库sql文件如下：
• seata官网文档 nacos注册中心，db存储说明文档打开**[建表脚本]**即可跳转到sql文件页面

seata配置nacos注册中心

• 在服务器上可以手动创建并编辑application.yml文件。如果你使用1Panel可以尝试将存储路径设置为/opt/1panel/apps/seata/data/conf/application.yml方便容器的管理。
• 配置文件内容如下：

server:
  port: 7091

spring:
  application:
    name: seata-server

logging:
  config: classpath:logback-spring.xml
  file:
    path: ${log.home:${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:
    type: nacos
    nacos:
      server-addr: IP:8848 #请将IP修改为部署nacos服务的服务器IP 默认端口8848
      namespace: seata-server #和nacos命名空间一致
      group: SEATA_GROUP
      username: nacos
      password: nacos
      data-id: seataServer.yaml #定义nacos配置文件名称，此文件配置db信息
  registry:
    type: nacos
    nacos:  
      application: seata-server
      server-addr: IP:8848  #请将IP修改为部署nacos服务的服务器IP 默认端口8848
      group: SEATA_GROUP
      namespace: seata-server
      cluster: default
      username: nacos
      password: nacos
  security:
    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
    tokenValidityInMilliseconds: 1800000
    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.jpeg,/**/*.ico,/api/v1/auth/login,/version.json

准备docker-compose.yaml文件

• 在/opt/1panel/apps/seata/目录下创建docker-compose.yaml文件

version: "3"
services:
  seata-server:
    image: seataio/seata-server:latest
    hostname: seata-server
    container_name: seata
    ports:
      - "8091:8091"
      - "7091:7091"
    environment:
      - SEATA_PORT=8091
      - TZ=Asia/Shanghai
      - SEATA_IP=linuxServer_IP  # linuxServer_IP:注册nacos时使用该地址，保证seata和其他应用正常通信
      - STORE_MODE=db #设置存储模式为database
    volumes:
      - ./data/conf/application.yml:/seata-server/resources/application.yml

启动seata容器

# 进入compose文件目录
cd /opt/1panel/apps/seata
# 部署seata
docker-compose up -d
