Error: unable to perform an operation on node
'rabbit@Xcm-PC'. Please see diagno
stics information and suggestions below.
Most common reasons for this are:
* Target node is unreachable (e.g. due to hostname resolution, TCP connection o
r 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
http://rabbitmq.com/document
ation.html to learn more
* Consult server logs on node rabbit@Xcm-PC
DIAGNOSTICS
===========
attempted to contact: ['rabbit@Xcm-PC']
rabbit@Xcm-PC:
* connected to epmd (port 4369) on Xcm-PC
* epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traff
ic
* TCP connection succeeded but Erlang distribution failed
* Authentication failed (rejected by the remote node), please check the Erlang
cookie
Current node details:
* node name: 'rabbitmqcli20@Xcm-PC'
* effective user's home directory: C:\Users\Xcm
* Erlang cookie hash: RmzKErjVZUcsMU8wSgBGbA==
根據提示顯示應該是Cookie出現問題。
1. 解決方式：修改Cookie信息，搜索.erlang.cookie文件，保證兩個Cookie文件一致。
兩個文件不一致，將兩個文件內容保持一致。重新操作，OK.
