Chef-server-ctl reconfigure command does not working


I am trying to install Chef 12 version into Red Hat 7.2. I have followed up the chef installation document. When I try to run the second steps in the document

  1. chef-server-ctl reconfigure . I was getting below the error

]$ sudo chef-server-ctl reconfigure
[sudo] password for ababa01010:

Please let me know if there is any command to execute before this reconfigure
