Ejabberd is not running in that node error

Hi, I'm trying to configure ejabberd without success.
Service is running at Debian Sid and when i type: # ejabberdctl register willian 123456
I get the output:

The node 'ejabberd@willian-notebook' is started with status: started
ejabberd is not running in that node
Check for error messages: ejabberd.log
or other files in that directory.

Solution :



    I have encounter same problem many times. after some times i analysis that

 first run this command

ejabberdctl register admin localhost password

then configure ejabberd.cfg file

 ,so i remove the ejabberd from linux. and install again but my problem comes again.

after try 2-3 times i used purge( see what is difference between purge and remove )command for remove ejabberd and insall again and follow these 

tutorial . and it works
