開發Spring Cloud Alibaba微服務應用時，mysql、redis和nacos要先搭建好，本文使用docker搭建；html

nacos有多種部署方式，見官方文檔：nacos docker，這裏用的是單機模式mysql模式，因此會與mysql會有關聯；mysql

docker-compose.yaml定義文件以下：nginx

version: "3.6"
services:
  mysql:
    image: mysql:${MYSQL_VERSION}
    container_name: mysql
    ports:
      - "${MYSQL_HOST_PORT}:3306"
    volumes:
      - ${MYSQL_CONF_FILE}:/etc/mysql/conf.d/mysql.cnf:ro
      - ${MYSQL_DATA_DIR}:/var/lib/mysql/:rw
    restart: on-failure
    networks:
      - default
    environment:
      MYSQL_ROOT_PASSWORD: "${MYSQL_ROOT_PASSWORD}"
      TZ: Asia/Shanghai

  redis:
    image: redis:${REDIS_VERSION}
    container_name: redis
    environment:
      TZ: Asia/Shanghai
    volumes:
      - ${REDIS_LOG_DIR}:/var/log/redis/:rw
      - ${REDIS_CONF_FILE}:/usr/local/etc/redis/redis.conf:ro
      - ${REDIS_DIR}:/var/lib/redis/6379/:rw
    command:
      - /usr/local/etc/redis/redis.conf
    restart: on-failure
    networks:
      - default
    ports:
      - "${REDIS_HOST_PORT}:6379"

  nacos:
    image: nacos/nacos-server:${NACOS_VERSION}
    container_name: nacos
    environment:
      - "PREFER_HOST_MODE=${PREFER_HOST_MODE}"
      - "MODE=${MODE}"
      - "SPRING_DATASOURCE_PLATFORM=${SPRING_DATASOURCE_PLATFORM}"
      - "MYSQL_SERVICE_HOST=${MYSQL_SERVICE_HOST}"
      - "MYSQL_SERVICE_DB_NAME=${MYSQL_SERVICE_DB_NAME}"
      - "MYSQL_SERVICE_PORT=${MYSQL_SERVICE_PORT}"
      - "MYSQL_SERVICE_USER=${MYSQL_SERVICE_USER}"
      - "MYSQL_SERVICE_PASSWORD=${MYSQL_SERVICE_PASSWORD}"
    volumes:
      - ${NACOS_LOG_DIR}:/home/nacos/logs:rw
      - ${NACOS_PROPERTIES}:/home/nacos/init.d/custom.properties
    depends_on:
      - mysql
    ports:
      - 8848:8848
    restart: on-failure
    
networks:
  default:

值得注意的是，這裏nacos版本是1.2.1,同時初始化的sql腳本nacos-mysql，能夠從nacos-mysql腳本取得；redis

啓動服務：sql

docker-compose -f docker-compose.yml up -d
Starting redis ... done
Starting mysql ... done
Starting nacos ... done
