seata部署

docker-compose db nacos 模式

准备数据库表

数据库表: https://github.com/apache/incubator-seata/tree/develop/script/server/db

准备compose.yaml文件

version: "3.1"
services:
  seata-server:
    image: seataio/seata-server:1.5.2
    ports:
      - "7091:7091"
      - "8091:8091"
    environment:
      - STORE_MODE=db
      # 以SEATA_IP作为host注册seata server
      - SEATA_IP=192.168.208.128
      - SEATA_PORT=8091
    volumes:
      - "/usr/share/zoneinfo/Asia/Shanghai:/etc/localtime"        #设置系统时区
      - "/usr/share/zoneinfo/Asia/Shanghai:/etc/timezone"  #设置时区
      # 假设我们通过docker cp命令把资源文件拷贝到相对路径`./seata-server/resources`中
      # docker cp 容器id:/seata-server/resources ./resource 这步不能少
      # 如有问题，请阅读上面的[注意事项]以及[使用自定义配置文件]
      - "./resources:/seata-server/resources"
    networks:
    # 外部db数据库网络，需要先启动mysql容器，可以单独布置，或者放在这里一起布置
      - hm-net
          
networks:
  hm-net:
    external: true # 来自外部

准备application.yaml文件

https://github.com/apache/incubator-seata/blob/develop/server/src/main/resources/application.example.yml

application 例子 注意，将/seata-server/resources拷贝出来后需要将里面的application替换

server:
  port: 7091

spring:
  application:
    name: seata-server
    
console:
  user:
    username: liuyaowen
    password: 123123

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

seata:
  config:
    # support: nacos 、 consul 、 apollo 、 zk  、 etcd3
    type: nacos
    nacos:
      server-addr: 192.168.208.128:8848
      namespace: 9194952e-02a9-4737-89c2-1f3dee3317f0
      group: SEATA_GROUP
      username:

      context-path:
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key:
      #secret-key:
      data-id: seataServer.properties
  registry:
    # support: nacos 、 eureka 、 redis 、 zk  、 consul 、 etcd3 、 sofa
    type: nacos
    preferred-networks: 30.240.*
    nacos:
      application: seata-server
      server-addr: 192.168.208.128:8848
      group: SEATA_GROUP
      namespace: 9194952e-02a9-4737-89c2-1f3dee3317f0
      cluster: default
      username:

      context-path:
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key:

    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
    tokenValidityInMilliseconds: 1800000
    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

  metrics:
    enabled: false
    registry-type: compact
    exporter-list: prometheus
    exporter-prometheus-port: 9898
  transport:
    rpc-tc-request-timeout: 15000
    enable-tc-server-batch-send-response: false
    shutdown:
      wait: 3
    thread-factory:
      boss-thread-prefix: NettyBoss
      worker-thread-prefix: NettyServerNIOWorker
      boss-thread-size: 1

之后还需要在nacos中配置好seata的配置 nacos 配置例子
