RabbitMQ启动配置中出现(ArgumentError) argument error xxx的错误

1. 最近在安装RabbitMQ中，输入rabbitmqctl status后出现这样的错误

Status of node rabbit@Desktopxxxxx ** (ArgumentError) argument error (stdlib) io_lib.erl:170: :io_lib.format(' * effective user's home directory: sn', [[67, 58, 92, 85, 115, 101, 114, 115, 92, 37329, 20108, 33804]]) src/rabbit_misc.erl:668: :rabbit_misc."-format_many/1-lc

^0/1-0-"/1 src/rabbit_misc.erl:668: :rabbit_misc.format_many/1 (rabbitmqctl) lib/rabbitmqctl.ex:349: RabbitMQCtl.get_node_diagnostics/1 (rabbitmqctl) lib/rabbitmqctl.ex:307: RabbitMQCtl.format_error/3 (rabbitmqctl) lib/rabbitmqctl.ex:43: RabbitMQCtl.main/1 (elixir) lib/kernel/cli.ex:105: anonymous fn/3 in Kernel.CLI.exec_fun/2

网上查阅后发现是win的账户是中文名导致的错误，需要将中文名修改成英文名。参考的是这篇文章的方法修改。

1. 一般情况下1操作后RabbitMQ是不会载出问题的，然鹅，我再输入rabbitmqctl status后又出现了这样的报错

Status of node rabbit@DESKTOP-xxxxxx ... Error: unable to perform an operation on node 'rabbit@DESKTOP-xxxxxx'. 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 http://rabbitmq.com/documentation.html to learn more * Consult server logs on node rabbit@DESKTOP-ECFDCQB DIAGNOSTICS =========== attempted to contact: ['rabbit@DESKTOP-xxxxxx'] rabbit@DESKTOP-xxxxxxxx: * connected to epmd (port 4369) on DESKTOP-xxxxxxx * epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traffic * TCP connection succeeded but Erlang distribution failed * Authentication failed (rejected by the remote node), please check the Erlang cookie Current node details: * node name: 'rabbitmqcli80@DESKTOP-xxxxxx' * effective user's home directory: C:\Users\tracyclock * Erlang cookie hash: Gue+A5xaV3AGwaGPZAEp3A==

解决方法有两种：

• (1) 将 C:\Users\Administrator下的erlang.cookie文件 替换C:\Windows\System32\config\systemprofile下的erlang.cookie 文件，然后再重启服务
• (2) 将RabbitMQ的登录账户由本地账户设为当前登录的用户，然后再重启服务，详情请见这篇博文https://blog.csdn.net/dear_Alice_moon/article/details/79466568

试过上述的方法后，重启服务后还是报第二种错误。于是我又看了一下安装路径，发现我的安装路径是D:\Program Files\RabbitMQ server.....我就想要不试一下换个路径安装，之后直接在D盘根目录D:\RabbitMQ server安装，居然成功了!!!

后面又查了一下，发现报错的原因是安装路径中有空格，但是一般安装RabbitMQ的时候默认是C:\Program Files...神坑，所以安装的时候一定要注意修改安装路径！不要有中文或者空格的目录。。。
