在rabbitmq中创建新节点后节点未启动答案

【问题标题】：Node not starting after creating a new node in rabbitmq在rabbitmq中创建新节点后节点未启动
【发布时间】：2019-05-06 05:49:37
【问题描述】：

我想创建一个包含 3 个节点的集群。我用命令创建了两个节点：

RABBITMQ_NODE_PORT=5680 RABBITMQ_NODENAME=rabbit1@localhost rabbitmq-server -detached

现在，当我尝试停止节点以将其加入集群时，它给了我一个错误，指出节点根本没有启动。

到目前为止我所做的是安装rabbitmq并使用rabbitmq-server启动它。

rabbit1@localhost.log

Log file(s) (may contain more information):

终端：

Most common reasons for this are:

 * Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
 * CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
 * Target node is not running

In addition to the diagnostics info below:

 * See the CLI, clustering and networking guides on https://rabbitmq.com/documentation.html to learn more
 * Consult server logs on node rabbit1@localhost
 * If target node is configured to use long node names, don't forget to use --longnames with CLI tools

DIAGNOSTICS
===========

attempted to contact: [rabbit1@localhost]

rabbit1@localhost:
  * connected to epmd (port 4369) on localhost
  * epmd reports: node 'rabbit1' not running at all
                  other nodes on localhost: [rabbit]
  * suggestion: start the node

Current node details:
 * node name: 'rabbitmqcli-9206-rabbit@localhost'
 * effective user's home directory: /Users/yashparekh
 * Erlang cookie hash: +/3SPQl4T2w3zA11j1+o4Q==

我希望 stop_app 命令能够工作，以便能够将其加入集群。请让我知道我哪里出错了。

提前致谢。

{failed_to_start_child,
             {ranch_listener_sup,{acceptor,{0,0,0,0,0,0,0,0},1883}},
             {shutdown,
              {failed_to_start_child,ranch_acceptors_sup,
               {listen_error,
                {acceptor,{0,0,0,0,0,0,0,0},1883},
                eaddrinuse}}}}}}},

表示1883（MQTT 端口）端口已被使用。您还必须动态设置此端口。
