提问：Nacos部署No DataSource set问题

先跑起mysql数据库主从，并有nacos_config数据库。

有nacos-standalone-mysql.yaml 文件

[root@localhost example]# cat nacos-standalone-mysql.yaml 
version: "2"
services:
  nacos:
    image: nacos/nacos-server:latest
    container_name: nacos-standalone-mysql
    environment:
      - PREFER_HOST_MODE=hostname
      - MODE=standalone
      - SPRING_DATASOURCE_PLATFORM=mysql
      - MYSQL_MASTER_SERVICE_HOST=192.168.0.88
      - MYSQL_MASTER_SERVICE_DB_NAME=nacos_config
      - MYSQL_MASTER_SERVICE_PORT=3306
      - MYSQL_SLAVE_SERVICE_HOST=192.168.0.88
      - MYSQL_SLAVE_SERVICE_PORT=3307
      - MYSQL_MASTER_SERVICE_USER=root
      - MYSQL_MASTER_SERVICE_PASSWORD=root
    volumes:
      - ./standalone-logs/:/home/nacos/logs
      - ./init.d/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8848:8848"
      - "9555:9555"
    restart: on-failure
  prometheus:
    container_name: prometheus
    image: prom/prometheus:latest
    volumes:
      - ./prometheus/prometheus-standalone.yaml:/etc/prometheus/prometheus.yml
    ports:
      - "9090:9090"
    depends_on:
      - nacos
    restart: on-failure
  grafana:
    container_name: grafana
    image: grafana/grafana:latest
    ports:
      - 3000:3000
    restart: on-failure

启动命令 ：docker-compose -f nacos-standalone-mysql.yaml start 

查看日志:nacos.log

此时提示：未设置数据源

当前防火墙是开启状态

当关闭防火墙systemctl stop firewalld

关闭nacos  ： docker-compose -f nacos-standalone-mysql.yaml stop

再启动nacos ：docker-compose -f nacos-standalone-mysql.yaml start

此时的提示信息如下：

[root@localhost example]# docker-compose -f nacos-standalone-mysql.yaml start
Starting nacos ... error
Starting prometheus ... error
Starting grafana ... error

查看日志： tail -f nacos.log  ，没有新增内容。

然后，重启docker  。命令： systemctl restart docker 

从头再来执行一遍。

再启动mysql ，再启动 nacos ，如此可以启动nacos成功。

nacos.log如下：

请问这是为什么。。。如何解决不关闭防火墙也可以部署nacos ?

已解决。

办法：把docker-compose启动配置文件 nacos-standalone-mysql.yaml 中的所有端口，全部开放，就可以了。
