Redmine

Hi !

I'm trying to run redmine 0.9.2 (release from sourceforge) with nginx proxying to a mongrel_cluster and a Postgresql db. It does not work (yet) !
We can omit nginx for now, since I'm just trying with my mongrel cluster at the time.

If I run ruby script/server webrick -e production -p 3000, everything is ok, redmine runs, db is ok etc.
But if I try with mongrel with this conf (mongrel_cluster.yml is a link to /etc/mongrel_cluster/redmine.yml), I run into some problems :

$cat /etc/mongrel_cluster/redmine.yml
---
group: nginx
user: mongrel
log_file: /var/log/mongrel.log
address: 127.0.0.1
port: "8000"

pid_file: /home/mongrel/pids/mongrel.pid

$mongrel_cluster_ctl start -c /etc/mongrel_cluster -v
Starting all mongrel_clusters...
mongrel_rails cluster::start -C redmine.yml -v

mongrel_rails start -d -e production -a 127.0.0.1 -c /var/www/redmine --user mongrel --group nginx -p 8000 -P /home/mongrel/pids/mongrel.8000.pid -l /var/log/mongrel.8000.log

$mongrel_cluster_ctl status

mongrel_rails cluster::status -C redmine.yml

• Daemonized, any open files are closed. Look at /home/mongrel/pids/mongrel.8000.pid and /var/log/mongrel.8000.log for info.
• Starting Mongrel listening at 127.0.0.1:8000
• Initiating groups for "mongrel":"nginx".
• Changing group to "nginx".
• Changing user to "mongrel".
• Starting Rails with production environment...

if I try http://127.0.0.1:8000, I get an 'unable to connect' and if I start nginx (with an nginx conf proxying to mongrel_cluster that seems ok) I get a '502 bad gateway'. I don't know if mongrel_cluster is running ok, from what the logs says, I think it's not because it requires rack 1.0.0 and redmine require 1.0.1 ?
is that the problem ? and how can I fix this ?
