In my /etc/sudoers.d/myAppCommand file I set some command like this.
Cmnd_Alias APP_CMD = /opt/myApp/lib/app-start, \
/opt/myApp/lib/app-stop, \
/opt/myApp/lib/app-restart
#Rules section
#
my-app ALL = NOPASSWD: APP_CMD
But at the time of installation this command giving the below error:
2015-01-12 08:22:27 SecurityEvent sudo Rack1 alert sudo: my-app : no tty present and no askpass program specified ; TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/opt/myApp/lib/app-start
