After installing Erlang OTP and RabbitMQ, you need to verify the integrity of the Erlang OTP cookie.
Erlang nodes use a cookie to determine whether or not they are allowed to communicate with each other. For two nodes to communicate, they must have the same cookie.
The cookie is just a randomly generated string of alphanumeric characters. Erlang automatically creates this cookie when the RabbitMQ server starts.
During installation of RabbitMQ, two cookie files are created. The default locations for these files are:
- %SystemRoot%\.erlang.cookie (for example: C:\Windows\.erlang.cookie)
- %HOMEDRIVE%%HOMEPATH%\.erlang.cookie (for example: C:\Users\[username]\.erlang.cookie)
Sometimes (due to permissions or other reasons) these files are not the same.
If they are different, then you need to copy the file .erlang.cookie manually from %SystemRoot% to %HOMEDRIVE%%HOMEPATH%.
