Guillaume,

I completely feel your pain, the first time I tried to setup Koji was  
a bit of hell due to the lack of documentation and proper 'howtos'.  I  
haven't been using Koji for a while, and have only installed it twice  
so please excuse any ignorance on my part.

That said:

In the HowTo, did you follow the steps about creating the users/ 
passwords in PostGreSQL database directly, and getting PostGreSQL up  
and running?  Last I used Koji the utilities did not handle adding  
users, so those operations have do be done via SQL within PostGres.

Being that it is SSL, shouldn't these url addresses start with  
https:// rather than http://?  Again, forgive me as I haven't setup  
Koji in a long time.

1) I know you mentioned that the w.x.y.z IP Addresses were replaced  
here in your email with dummy ones, same for hostnames.  However,  
being that you are running everything on the same box, you may wish to  
consider using 'localhost'.  For one, if this server is NATd or behind  
a firefall (on private IPs) then using the real IP/Hostname may not  
work for you.  It would be best to use localhost, or the Primary IP  
that is configured on ETH0.  Additionally, if you are using hostnames  
you want to verify that the hostname is resolving to the IP that is  
configured on the NIC (not necessary the IP that the hostname should  
point to publicly).  Meaning if you are on a private network ensure  
that /etc/hosts is configured properly.

Looking at the apache log entries it really looks like the issue is  
with the PostGreSQL server.  Note the last log entry:

Can you verify that PostGreSQL is running on host  
'murrar.mysite.hp.com' (and that the address is resolvable and  
accessible just as stated.... meaning from the box that is running the  
web  frontends, can you ping the server (this goes back to the last  
stuff I was mentioning about 'localhost' etc.


Good luck.
