Install rabbitmq and environment erlang in windows (the most detailed version, including correspondence and installation error solutions)

Written at the front: I don’t know when to install an mq. I need to read countless articles before installing it. None of them explain it completely. Here is a detailed tutorial.

Delete old version correspondence:

    1.在官方文档中找到RabbitMQ版本对应的Erlang版本重新下载安装包

    文档RabbitMQ Erlang Version Requirements — RabbitMQ

    2.下载完成后停止Erlang和RabbitMQ服务并进入原本Erlang和RabbitMQ的安装目录，运行Uninstall.exe

    3.卸载完成后检查Erlang和RabbitMQ的安装目录是否删干净

    4.删除RabbitMQ和Erlang的所有安装目录。

    5.运行CMD-->sc delete RabbitMQ

    6.删除目录C:\Windows\System32\config\systemprofile中的.erlang.cookie文件（如果有的话）。

    7.删除目录C:\Users\用户名  中的.erlang.cookie文件（如果有的话）。

    8.删除目录C:\Users\用户名\AppData\Roaming目录下的RabbitMQ文件夹。

    9.打开注册表编辑器，删除表,计算机\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Ericsson\Erlang下的子项

    10.以管理员运行分别运行Erlang和RabbitMQ安装包即可

2. Here we take mq-3.10.18 and erlang-24.3.3 as examples (although the official description states that 3.10.18 corresponds to the 24.4 version of erlang, personal testing requires at least 24.3.2 to support mq-3.10.18)
