安裝部署rabbitmq報錯——已解決

安裝部署rabbitmq時報錯：

Error: unable to perform an operation on node '[email protected]'. Please see diagnostics information and suggestions below.

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 [email protected]
 * If target node is configured to use long node names, don't forget to use --longnames with CLI tools

原因：rabbitmq主控端無法解析本機的主機名；

解決方式：編輯/etc/hosts檔案，添加主機名映射

編輯後端hosts檔案如下圖所示（主機名為ramq）：
