问题描述

我有两个节点，每个节点上都安装了带有 Mesos、marathon 和 zookeeper 的 docker.这是我在主节点上的 docker compose 文件:

这是从节点的docker compose:

我在zoo.cfg"上配置了 Zookeeper 并为每个节点制作了myid"文件.我还配置了 Mesos 和 Marathon.但是当我在主节点 (150.20.11.133) 上运行 docker compose 时，出现了这个错误:

我不知道发生了什么.我尝试使用 ufw 打开每个端口，或者我禁用了防火墙，但错误并没有消失.你能告诉我 docker compose 文件有什么问题吗?

任何帮助将不胜感激.

谢谢.

解决方案

我刚刚重新启动了zookeeper"，一切都很顺利.

./ZOOKEEPER_HOME/bin/zkServer.sh 重启

I have two nodes that each one has docker with Mesos,marathon,and zookeeper have been installed on it. This is my docker compose file on master node:

version: '3.7'
 services:
  zookeeper:

This is docker compose for slave node:

      - 2190
    ports:

      - 2190:2190

I configured Zookeeper on "zoo.cfg" and made "myid" file for every node. Also I configured Mesos and Marathon. But when I ran docker compose on master node (150.20.11.133), I got this error:

marathon_1 | java.net.ConnectException: Connection refused marathon_1 | at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method)

I don't know what happen. I tried to open every port with ufw or I disabled firewall, but error did not go away. Would you please tell me what is wrong with docker compose file?

Any help would be appreciated.

Thanks.

解决方案

I just restarted "zookeeper" and everything went fine.

./ZOOKEEPER_HOME/bin/zkServer.sh restart
