Mongrel users - Aug 2006 - Mongrel loading wrong database environment (& a couple other bugs?)

Hi There,

I''ve got a mongrel cluster running on redhat 9 proxied behind an  
Apache 2.2 installation.  I have run into a real stumbling block in  
that, while the rails app runs in production mode (you get a  
production.log file, for example, and I see this in the mongrel log:  
** Starting Rails with production environment ... ), it always loads  
the development database configuration no matter what. I can re- 
config the file, move things around, with no effect.  Has anyone else  
noticed this?

I''m starting up mongrel using the mongrel_cluster_ctl script from /et/ 
init.d/mongrel_cluster as suggested in the docs. You can see my  
config file below.


I''ve also noticed a couple other issues.

1. When specifying a pid file that''s not in the default, you can  
start up mongrel fine and it writes the pid(s, this is clustered) to  
the correct location, say /tmp/mongrel.*.pid, but the stop command  
always tries to find the pid in /path/to/docroot/log/tmp/ 
mongrel.*.pid, basically appending the absolute path to the default  
location.

This is handy if you want to move symlinks around and still have the  
ctl script find the pids.

2. the -r (--root) option and the :docroot yml pair don''t seem to  
have any effect whatsoever.


Thanks for any help you can offer,

John Clayton




My mongrel versions:

mongrel (0.3.13.3)
     A small fast HTTP library and server that runs Rails, Camping, and
     Nitro apps.

mongrel_cluster (0.2.0)
     Mongrel plugin that provides commands and Capistrano tasks for
     managing multiple Mongrel processes.



My config file:

---
user: mongrel
cwd: /var/www/example.com/app/current/
port: "8000"
environment: production
debug: false
group: instrument
address: 127.0.0.1
pid_file: log/mongrel.pid
servers: 3

Not sure what Mongrel would do to cause this, and since many other
people are running in production with Mongrel you should double check
your database.yml config and your database config.  Best thing to do is
remove *everything* from database.yml except your production setup, and
remove all databases except your production database.  But, uh don''t do
this on real production, do it some test environment.

If you do this then you''ll quickly find out why it''s wrong and
can go
fix your configuration.

This is fixed in the 0.3.13.4 pre-release.  If you have a chance, double
confirm it by installing the pre-release on your development or staging
system:

  gem install mongrel --source=http://mongrel.rubyforge.org/releases/

Can you describe this a bit better?  Also tell me if you see this stil
with the pre-release.

Oh, one more thing, also make sure that your setup runs in production
*without* mongrel_cluster and with webrick.  If it works in plain
mongrel then it might be a mongrel_cluster bug.  If it works with
webrick then it might be a mongrel bug.
