Reports

In my case, RabbitMQ version is 4.2.0.
I have already installed RabbitMQ successfully, enabled rabbitmq_management plugin as well.
I found the error: The Erlang cookie used by the RabbitMQ server and your CLI client do not match. Fixing this usually involves editing the .erlang.cookie file.

For the RabbitMQ server, you can find out this file with follow path C:\Windows\System32\config\systemprofile\AppData\Roaming\RabbitMQ.erlang.cookie
In my case, the content of file is HQYDPYUYZQFES******
For your user account (CLI client), you can find out this file with follow path C:\Users<your_username>.erlang.cookie
In my case, the content of file is OGIHLSSKESAFW******
After that, you need synchronize content of these files. You run Windows PowerShell by Administrator with follow script

$serverCookiePaths = @(
    "$env:APPDATA\RabbitMQ\.erlang.cookie",
    "$env:WINDIR\system32\config\systemprofile\AppData\Roaming\RabbitMQ\.erlang.cookie"
)

$userCookiePath = "$env:USERPROFILE\.erlang.cookie"

foreach ($path in $serverCookiePaths) {
    if (Test-Path $path) {
        Copy-Item $path $userCookiePath -Force
        Write-Host "content of these files .erlang.cookie synchronized."
        break
    }
}

You need restart RabbitMQ server by command lines in RabbitMQ Command Prompt (sbin dir) with Administrator permission

rabbitmq-service.bat stop
rabbitmq-service.bat start
rabbitmqctl.bat status
rabbitmq-plugins.bat enable rabbitmq_management
