开发Spring Cloud Alibaba微服务利用时，mysql、redis和nacos要先搭建好，本文应用docker搭建；
nacos有多种部署形式，见官网文档：nacos docker，这里用的是单机模式mysql模式，所以会与mysql会有关联；
docker-compose.yaml定义文件如下：
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: 环境变量.env:

启动服务：
docker-compose -f docker-compose.yml up -dStarting redis ... doneStarting mysql ... doneStarting nacos ... done查看服务和端口状况：
