Chef server install error, can not access the login web site

Hi, every one.
I just installed chef server x64 in rehl5/6.
But on both the rh servers, I could access the login web site.
I try to use chef-server-ctl to find out what happened.
Here below is the error message.
Do anybody know how to fix it?
Thanks.
