Pem files are not created in chef-server

Chef Infra (archive)
1

Hi,

 I am using open source chef server,in which pem files are not

created in /etc/chef-server only two files are there
1)chef-server-running.json2)chef-server-secrets.json

 I ve extract a pkg using
        1)dpkg -i pkg name  then
         2)use sudo chef-server-ctl reconfigure

but its not creating pem files why?

Thanks,
Indra
