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
[root@localhost ~]# systemctl status firewalld ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled) Active: active (running) since 六 2019-10-05 22:01:28 CST; 12min ago Docs: man:firewalld(1) Main PID: 9561 (firewalld) Tasks: 2 Memory: 22.0M CGroup: /system.slice/firewalld.service └─9561 /usr/bin/python2 -Es /usr/sbin/firewalld --nofork --nopid 10月 05 22:01:28 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon... 10月 05 22:01:28 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon. 10月 05 22:01:29 localhost.localdomain firewalld[9561]: WARNING: COMMAND_FAILED: '/usr/sbin/iptables -w10 -D FORWARD -i docker0 -o docker0 -j DROP' failed: iptables: Bad rule (does a matching ...that chain?). 10月 05 22:01:29 localhost.localdomain firewalld[9561]: WARNING: COMMAND_FAILED: '/usr/sbin/iptables -w10 -D FORWARD -i br-f43a2f3c90e1 -o br-f43a2f3c90e1 -j DROP' failed: iptables: Bad rule (...that chain?). 10月 05 22:01:29 localhost.localdomain firewalld[9561]: WARNING: COMMAND_FAILED: '/usr/sbin/iptables -w10 -D FORWARD -i docker0 -o docker0 -j DROP' failed: iptables: Bad rule (does a matching ...that chain?). Hint: Some lines were ellipsized, use -l to show in full.
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 ERROR: for nacos Cannot start service nacos: driver failed programming external connectivity on endpoint nacos-standalone-mysql (84f0c6a2500462d6476feef183de51cf348b21000cafd96f0d0f65b5a853e73f): (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 9555 -j DNAT --to-destination 172.18.0.2:9555 ! -i br-f43a2f3c90e1: iptables: No chain/target/match by that name.

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 ?
