erlang - ejabberdctl not found in bash Ubuntu(installing ejabberd)

i trying install ejabberd applying tutorials in many site vm ubuntu stuck in beginning. after wrote

sudo  apt-get update sudo apt-get -y install ejabberd

it installs ejabberd. when try write following

ejabberdctl register admin localhost mypassword

it says ejabberdctl not found. tried restart still same.

sudo service ejabberd restart

ejabberdctl owned root 550 permissions installed in /usr/sbin meaning non-root users can not execute binary. try:

sudo ejabberdctl register admin localhost mypassword

sudo elevates privileges root in terminal (after entering password) giving access binary.
