1.使用vsCode打開需要創(chuàng)建的文件，直觀表示

2.數(shù)據(jù)庫連接配置 nacos-server.env

#nacos dev env
MODE=cluster
PREFER_HOST_MODE=hostname
NACOS_SERVERS=nacos1:8848 nacos2:8848 nacos3:8848
MYSQL_SERVICE_HOST=127.0.0.1
MYSQL_SERVICE_DB_NAME=nacos_config
MYSQL_SERVICE_PORT=3306
MYSQL_SERVICE_USER=**
MYSQL_SERVICE_PASSWORD=**

3.init.d目錄下創(chuàng)建自定義配置文件custom.properties

#spring.security.enabled=false
#management.security=false
#security.basic.enabled=false
#nacos.security.ignore.urls=/**
#management.metrics.export.elastic.host=http://localhost:9200
# metrics for prometheus
management.endpoints.web.exposure.include=*
# metrics for elastic search
#management.metrics.export.elastic.enabled=false
#management.metrics.export.elastic.host=http://localhost:9200
# metrics for influx
#management.metrics.export.influx.enabled=false
#management.metrics.export.influx.db=springboot
#management.metrics.export.influx.uri=http://localhost:8086
#management.metrics.export.influx.auto-create-db=true
#management.metrics.export.influx.consistency=one
#management.metrics.export.influx.compressed=true

4.Docker-compose的yml文件：cluster-nacos-server.yml

version: "3"
services:
  nacos1:
    hostname: nacos1
    container_name: nacos1
    image: nacos/nacos-server:latest
    volumes:
      - ./cluster-logs/nacos1:/home/nacos/logs
      - ./init.d/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8845:8848"
      - "9555:9555"
    env_file:
      - ../env/nacos-server.env
    restart: always
  nacos2:
    hostname: nacos2
    image: nacos/nacos-server:latest
    container_name: nacos2
    volumes:
      - ./cluster-logs/nacos2:/home/nacos/logs
      - ./init.d/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8846:8848"
    env_file:
      - ../env/nacos-server.env
    restart: always
  nacos3:
    hostname: nacos3
    image: nacos/nacos-server:latest
    container_name: nacos3
    volumes:
      - ./cluster-logs/nacos3:/home/nacos/logs
      - ./init.d/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8847:8848"
    env_file:
      - ../env/nacos-server.env
    restart: always

啟動

docker-compose -f cluster-nacos-server.yml up -d
