I've installed Erlang and rabbitmq. After that started the service

$ sudo systemctl start rabbitmq-server
$ systemctl status rabbitmq-server
● rabbitmq-server.service - RabbitMQ broker
Loaded: loaded (/usr/lib/systemd/system/rabbitmq-server.service; disabled; vendor preset: disabled)
Active: active (running) since Fri 2018-10-19 10:50:10 CEST; 13s ago
Main PID: 46976 (beam.smp)
CGroup: /system.slice/rabbitmq-server.service
├─46976 /usr/lib64/erlang/erts-5.10.4/bin/beam.smp -W w -K true -A30 -P 1048576 -- -root /usr/li...
├─47073 inet_gethost 4
└─47075 inet_gethost 4

Then I enabled rabbitmq-management, and changed ownership

$ sudo rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management
Plugin configuration has changed. Restart RabbitMQ for changes to take effect.
$ sudo chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/

Than created user, tag him and set permissions

$ sudo rabbitmqctl add_user admin password!
Creating user "admin" ...
...done.
$ sudo rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
...done.
$ sudo rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
Setting permissions for user "admin" in vhost "/" ...
...done.

And bad happend there, I'm not able to restart the rabbitmq anyhow


$ sudo systemctl status rabbitmq-server.service

What should I do to get rabbitmq start again?
Thanks

I foud answer here: https://github.com/rabbitmq/chef-cookbook/issues/182

In logs file i found:

`=INFO REPORT==== 19-Oct-2018::12:19:04 ===

All I had to do is to change permissions to /etc/rabbitmq/enabled_plugins by

chmod 644 /etc/rabbitmq/enabled_plugins

And it started now.
Thanks

I had the same issue with windows. I didn't find a solution by googling.
{error,{cannot_read_enabled_plugins_file,"C:RabbitMQENABLE~1",eisdir}}
I had set my HOMEDRIVE and HOMEPATH configured in environment variables as c: and RabbitMQ. But rabbimq ignore these values.

I had a folder named "enabled_plugins" in C:RabbitMQ folder. RabbitMQ is expecting a file in %HOMEDRIVE%%HOMEPATH% folder.

Solution was to delete enabled_plugins folder at C:RabbitMQ path and create the file named enabled_plugins in %HOMEDRIVE%%HOMEPATH% folder.

Other steps involved:

1) Install erlang. check if environment variables point to correct erlang path
In my case envName:ERLANG_HOME value: C:Program Fileserl10.0.1

2) Install RabbitMQ windows installer

3) Configure fire wall(if necessary). see Advanced Firewall setting(see on left panel of Firewall settings) from Control Panel.

Add new rules based on below.

Rule Type Port
Protocols and Ports TCP
Specified local ports 5672, 15672
Action Allow the connection
Profile Domain, Private, Public
Name RabbitMQ

Rule Type Program
Program path %ProgramFiles%erl7.2.1binerl.exe
Action Allow the connection
Profile Domain, Private, Public
Name Erlang

Rule Type Program
Program path %ProgramFiles%erl10.0.1erts-10.0.1binerl.exe
Action Allow the connection
Profile Domain, Private, Public
Name Erlang RunTime

Rule Type Program
Program path %ProgramFiles%erl10.0.1erts-10.0.1binepmd.exe
Action Allow the connection
Profile Domain, Private, Public
Name Erlang Port

4) Copy RabbitMQ folder from %APPDATA% to C: drive and delete from %APPDATA% folder

(This can be done after signout and re-log-in).

5) Set environment variable (system variables) RABBITMQ_BASE = C:RabbitMQ and RABBITMQ_MNESIA_BASE= C:RabbitMQdb, make sure db folder exist.

6) Run RabbitMQ command prompt (Run As Administrator) (or command prompt path C:Program FilesRabbitMQ Serverrabbitmq_server-3.7.8sbin)

7) SET HOMEDRIVE=C: SET HOMEPATH=RabbitMQ from command prompt

8) rabbitmq-service.bat remove

9) rabbitmq-service.bat install

10) rabbitmq-service.bat start

11) rabbitmq-plugins.bat enable rabbitmq_management (if authentication didn't match check erlang cookie)

12) rabbitmqctl.bat status (to check status)

13) remove readonly attribute from C:WindowsSystem32configsystemprofile.erlang.cookie file.(right click properties)

14) Make sure cookies at C:WindowsSystem32configsystemprofile content is same as
%HOMEDRIVE%%HOMEPATH%.erlang.cookie

15)http://localhost:15672/#/, you should see the login screen.

16) login with guest/guest and create virual host and configure your bus(sender). Start your background service pointing to this virtual host.
