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

attempted to contact: [‘rabbit@SC-201607101239‘]

rabbit@SC-201607101239:
  * connected to epmd (port 4369) on SC-201607101239
  * epmd reports node ‘rabbit‘ running on port 25672
  * TCP connection succeeded but Erlang distribution failed
  * suggestion: hostname mismatch?
  * suggestion: is the cookie set correctly?
  * suggestion: is the Erlang distribution using TLS?

current node details:
- node name: ‘rabbitmq-cli-27@SC-201607101239‘
- home dir: C:\Users\Administrator
- cookie hash: +Xg8GwzCRQiqRrJZqqF30A==

解决方法：

Synchronise Erlang Cookies (when running a manually installed Windows Service)

Erlang Security Cookies used by the service account and the user running rabbitmqctl.bat must be synchronised for rabbitmqctl.bat to function.

To ensure Erlang cookie files contain the same string, copy the .erlang.cookie file from the Windows directory (normally C:\WINDOWS\.erlang.cookie) to replace the user .erlang.cookie. The user cookie will be in the user‘s home directory (%HOMEDRIVE%%HOMEPATH%), e.g.C:\Documents and Settings\%USERNAME%\.erlang.cookie orC:\Users\%USERNAME%\.erlang.cookie (Windows Vista and later).

同步Erlang Cookies

具体操作：将 C:\WINDOWS\.erlang.cookie   同步到RabbitMq 启动用户 例如win10:C:\Users\%USERNAME%\.erlang.cookie
