Mongrel users - Nov 2006 - Setting up Mongrel and Apache , some direction needed

I have a site that is PHP on Apache / RedHat , but will send requests to a
subdomain (running Rails) for database operations.
I believe the set up should be to have ROR using Mongrel, and an Apache
virtual host passing requests from apache to mongrel.
Does this sound correct ?
I believe the Virtual Host is set up in Apache.
One of my problems is I can''t find the httpd.conf file for apache. 
Sounds
strange.
Currently Rails is in a folder under /var/www/html/railsapp

However I see that the Rails app is configured to this path
/home/virtual/site8/fst/var/www/html/railsapp.

Any one know what I should be looking for on the Apache side ?

TIA
Stuart

Sorry but it''s not clear what you need help with.  Do you just need to 
find the httpd.conf file?

if you''re on *nix machine, use the find command: find . -name
httpd.conf

I just ran into one glitch , found out we''re running Apache 2.0.54, so
no
mod_proxy_balance.  Any workarounds for that ?

I assume then that the init.d or rc.d script that starts apache on boot does
not specifiy a config file, but that apache uses the path that is compiled
in.  The only way I know to find that is to use strings(1).  When I run

    strings /usr/sbin/httpd | grep ''^/''

I get
--------
...
/home/buildcentos/rpmbuild/BUILD/httpd-2.0.52/server/config.c
/dev/null
/etc/httpd
/home/buildcentos/rpmbuild/BUILD/httpd-2.0.52/server/vhost.c
...
--------

The line "/etc/httpd" is the only line that even looks like a
candidate, and
it''s correct for me.

HTH,

Right, I found it , each virtual site has it''s own conf file.

Sorry, yes I did find the httpd.conf file and the include statement as to
where the site''s virtualhost file is.
However the problem I''m facing now is Apache is at version 2.0.54. My
understanding is that without
mod_proxy_balancer I''ll be at a loss of concurrent requests.
Wanting to know if there is any workaround without upgrading Apache ?

Sorry Stuart, I''m using 2.2.3 and don''t know of any workaround
for 2.0.x

Hi Stuart,

Since we''re using RHEL 4 (and cannot install things from source, for
various
reasons), I recently setup Apache 2.0.x to use a mongrel cluster just by 
using mod_proxy to randomise requests between the various mongrels.
It''s not
as good as real load balancing (and, we haven''t really tested it
properly
yet - comments very welcome!), but it certainly seems like the best option so 
far if you''re not able to install Pen/Pound/Apache 2.2...

For example, start three mongrels on 8000-8002, then something like this in 
your vhost should sort you out, but definitely read the manual:

  ProxyRequests Off
  ProxyPreserveHost On
  RewriteMap  servers rnd:///path/to/rewrite_map.conf
  RewriteRule ^/(images|stylesheets|javascripts)/?(.*) $0 [L]
  RewriteRule ^/(.*)$ http://localhost:${servers:ports}/$1 [P,L]

rewrite_map.conf:

  ports  8000|8001|8002

how''s this working for you?

have you tried pounding it yet?

you might try the rails_analyzer_tools gem to see how evenly that
distributes requests.

the show numb3rs has taught me that random is not always as even as we
believe. ;)

We haven''t had the need to really hammer it yet. We expect to be doing
that
later on this month, if that''s any use to you.

I hadn''t heard of that - thanks a lot!

Take it easy,
