seata除了使用文件作为默认的配置中心和服务发现外，还可以使用nacos，我们学习下如何配置：首先启动mysql、nacos、seata，然后copy默认配置进行修改

# docker run -d --name nacos -p 8848:8848 -e MODE=standalone -e MYSQL_MASTER_SERVICE_HOST=你的mysql所在ip -e MYSQL_MASTER_SERVICE_DB_NAME=nacos -e MYSQL_MASTER_SERVICE_USER=root -e MYSQL_MASTER_SERVICE_PASSWORD=mysql密码 -e MYSQL_SLAVE_SERVICE_HOST=你的mysql所在ip -e SPRING_DATASOURCE_PLATFORM=mysql -e MYSQL_DATABASE_NUM=1 nacos/nacos-server:latest


# docker run -d --name seata -p 8091:8091 -e SEATA_IP=你想指定的ip -e SEATA_PORT=8091 seataio/seata-server:1.4.2




version: "3.1"
services:
  mysql:
    image: mysql:5.7
    container_name: mysql
    environment:
      - MYSQL_ROOT_PASSWORD=123456
    command: --default-authentication-plugin=mysql_native_password --default-time-zone='+08:00'
    volumes:
      - ./mysql:/docker-entrypoint-initdb.d
      - ./mysql/mysqld.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf
    ports:
      - "3306:3306"
    extra_hosts:
     - host.docker.internal:host-gateway


  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=host.docker.internal
      # - 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
      # 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]
      - /Users/xiazemin//resources:/seata-server/resources
      - /Users/xiazemin/logs:/root/logs/seata/
    depends_on:
      - mysql
      - nacos
    extra_hosts:
     - host.docker.internal:host-gateway
  nacos:
    image: nacos/nacos-server:2.0.2
    ports:
     - "8848:8848"
    environment:
     - MODE=standalone
     - MYSQL_MASTER_SERVICE_HOST=host.docker.internal
     - MYSQL_MASTER_SERVICE_DB_NAME=nacos
     - MYSQL_SERVICE_HOST=host.docker.internal
     - MYSQL_SERVICE_DB_NAME=nacos
     - MYSQL_SERVICE_USER=root
     - MYSQL_SERVICE_PASSWORD=123456
     - MYSQL_MASTER_SERVICE_USER=root
     - MYSQL_MASTER_SERVICE_PASSWORD=123456
     - MYSQL_SLAVE_SERVICE_HOST=host.docker.internal
     - SPRING_DATASOURCE_PLATFORM=mysql
     - MYSQL_DATABASE_NUM=1
     - NACOS_AUTH_SYSTEM_TYPE=nacos
    volumes:
     - /Users/xiazemin/nacos/conf:/home/nacos/conf
     - /Users/xiazemin/nacos/data:/home/nacos/data
    depends_on:
      - mysql
    extra_hosts:
     - host.docker.internal:host-gateway

然后，首先修改nacos的配置文件/nacos/conf/application.properties

# spring
server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}
server.contextPath=/nacos
server.port=${NACOS_APPLICATION_PORT:8848}
spring.datasource.platform=${SPRING_DATASOURCE_PLATFORM:""}
nacos.cmdb.dumpTaskInterval=3600
nacos.cmdb.eventTaskInterval=10
nacos.cmdb.labelTaskInterval=300
nacos.cmdb.loadDataAtStart=false
db.num=${MYSQL_DATABASE_NUM:1}
db.url.0=jdbc:mysql://${MYSQL_SERVICE_HOST}:${MYSQL_SERVICE_PORT:3306}/${MYSQL_SERVICE_DB_NAME}?${MYSQL_SERVICE_DB_PARAM:characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false}&serverTimezone=UTC
db.url.1=jdbc:mysql://${MYSQL_SERVICE_HOST}:${MYSQL_SERVICE_PORT:3306}/${MYSQL_SERVICE_DB_NAME}?${MYSQL_SERVICE_DB_PARAM:characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false}&serverTimezone=UTC
db.user=${MYSQL_SERVICE_USER}
db.password=${MYSQL_SERVICE_PASSWORD}
### The auth system to use, currently only 'nacos' is supported:
nacos.core.auth.system.type=${NACOS_AUTH_SYSTEM_TYPE:nacos}




### The token expiration in seconds:
nacos.core.auth.default.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000}


### The default token:
nacos.core.auth.default.token.secret.key=${NACOS_AUTH_TOKEN:SecretKey012345678901234567890123456789012345678901234567890123456789}


### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
nacos.core.auth.caching.enabled=${NACOS_AUTH_CACHE_ENABLE:false}
nacos.core.auth.enable.userAgentAuthWhite=${NACOS_AUTH_USER_AGENT_AUTH_WHITE_ENABLE:false}
nacos.core.auth.server.identity.key=${NACOS_AUTH_IDENTITY_KEY:serverIdentity}
nacos.core.auth.server.identity.value=${NACOS_AUTH_IDENTITY_VALUE:security}
server.tomcat.accesslog.enabled=${TOMCAT_ACCESSLOG_ENABLED:false}
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D
# default current work dir
server.tomcat.basedir=
## spring security config
### turn off security
nacos.security.ignore.urls=${NACOS_SECURITY_IGNORE_URLS:/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**}
# metrics for elastic search
management.metrics.export.elastic.enabled=false
management.metrics.export.influx.enabled=false


nacos.naming.distro.taskDispatchThreadCount=10
nacos.naming.distro.taskDispatchPeriod=200
nacos.naming.distro.batchSyncKeyCount=1000
nacos.naming.distro.initDataRatio=0.9
nacos.naming.distro.syncRetryDelay=5000
nacos.naming.data.warmup=true


service.vgroupMapping.default_tx_group=default
### Security ###
nacos.core.auth.enabled=true
nacos.core.auth.username=nacos
nacos.core.auth.password=nacos

然后修改seata的配置文件/resources/application.yml

server:
  port: 7091


spring:
  application:
    name: seata-server


logging:
  config: classpath:logback-spring.xml
  file:

      destination: 127.0.0.1:4560
    kafka-appender:

      topic: logback_to_logstash


console:
  user:
    username: seata
    password: seata


seata:
  config:

    nacos:

      namespace:
      group: SEATA_GROUP
      username: nacos
      password: nacos
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
      data-id: seataServer.properties
  registry:

    type: nacos #file
    nacos:
      application: seata-server
      server-addr: host.docker.internal:8848
      group: SEATA_GROUP
      namespace:
      cluster: default
      username: nacos
      password: nacos
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
  store:
    # support: file 、 db 、 redis
    mode: db
    db:
      datasource: druid
      dbType: mysql
      # 需要根据mysql的版本调整driverClassName
      # mysql8及以上版本对应的driver：com.mysql.cj.jdbc.Driver
      # mysql8以下版本的driver：com.mysql.jdbc.Driver
      driverClassName: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://host.docker.internal:3306/seata_server?useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false

      max-wait: 5000
      
  #  server:
  #    service-port: 8091 #If not configured, the default is '${server.port} + 1000'
  security:
    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
    tokenValidityInMilliseconds: 1800000
    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

尝试启动

% docker compose -f ./seata/exp4/docker-compose.yaml up

查看效果，首先登录nacos的控制端

http://127.0.0.1:8848/nacos/#/login，输入用户名：nacos，密码：nacos可以看到下面界面

至此配置中心启动成功
