win7安裝rabbitMQ后，執行命令
rabbitmqctl status
驗證是否成功，結果報錯如下
Status of node rabbit@liuchang ... Error: unable to perform an operation on node 'rabbit@liuchang'. Please see diag nostics 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@liuchang DIAGNOSTICS =========== attempted to contact: [rabbit@liuchang] rabbit@liuchang: * connected to epmd (port 4369) on liuchang * 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: rabbitmqcli35@liuchang * effective user's home directory: C:\Users\lc * Erlang cookie hash: sFQBZ2zBEp1D7xPVYArzwA==
解決辦法：
1、將C:\Users\username\.erlang.cookie 文件復制到 C:\Windows\System32\config\systemprofile 下，替換掉.erlang.cookie。
2、重啟rabbitMQ服務
net stop RabbitMQ net start RabbitMQ
