一、问题描述

安装完mq之后启动报错，查看状态也是一直是什么cooki，

[root@syld36 mnesia]# /etc/init.d/rabbitmq statusStatus of node rabbit@syld36 ...
Error: unable to perform an operation on node 'rabbit@syld36'. 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 runningIn 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 rabbit@syld36* If target node is configured to use long node names, don't forget to use --longnames with CLI toolsDIAGNOSTICS
===========attempted to contact: [rabbit@syld36]rabbit@syld36:* connected to epmd (port 4369) on syld36* epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traffic * can't establish TCP connection to the target node, reason: timeout (timed out)* suggestion: check if host 'syld36' resolves, is reachable and ports 25672, 4369 are not blocked by firewallCurrent node details:* node name: 'rabbitmqcli-255314-rabbit@syld36'* effective user's home directory: /root* Erlang cookie hash: GoBfPtMOwQFWNwGIjvTJJA==

二、解决方法

我先说解决办法：

在/etc/hosts 中增加一条：127.0.0.1 syld36 syld36 这是机器的主机名就解决了

解决思路：再错错误日志中，有一段“检查主机syld36是否解析”!!! 我就试着解析一下，还真成功了。哎。。。。遇到问题还是要看报错提示呀！！！！

查看服务器主机名 hostname

三、查看mq状态

/etc/init.d/rabbitmq status

这是安装mq的文章，/etc/init.d/rabbitmq 的启动脚本在下面这个文章中。
