OT:Mongrel and Apache

On the off chance someone might understand my dilemma I''m posting this:

Trying to set up Apache with a VirtualHost to pass requests to Mongrel with
mod_proxy.  Server is running an earlier version of RedHat 3.x maybe ?  and
Apache v.2.0 (right no mod_proxy_balancer)

I''m not a sys admin so kind of flying by the seat of my pants, though I
do
have the Mongrel deployment book.

The biggest problem right now is knowing where to put the VirtualHost.  My
rails app, while a sub folder under /var/www/html/railsapp
is configured like this:
/home/virtual/site8/fst/var/www/html/railsapp
I''ve seen a number of these virtual/site# locations. (i.e
virtual/site1,
virtual/site2, virtual/site3...................)

Yet I''ve looked in various httpd.conf files and find no configuration
for
these sites
Kind of confusing, and I know my question is just as confusing but if anyone
has any insight I''d appreciate it.

TIA
Stuart

Re: OT:Mongrel and Apache

This configuration, without mod_proxy_balancer, means you''ll only be  
able
to process one concurrent request at a time.

Performance is going to be severely limited.

Sounds like I should get an upgrade.

Re: OT:Mongrel and Apache

Are you hosting this on your own box or a VPS? If you''re using shared
hosting, I''d find someone who will let you proxy to something like
Pound. A
slightly less efficient alternative is to have Apache proxy to Pound and
have Pound do the load balancing among the Mongrel cluster.

I don''t know how well the latter suggestion would work. Anyone else
have any
opinions?

Hi Stuart,

The virtual hosts are probably being loaded via an include statement in
the httpd.conf, this allows you to easily manage all of the sites
individually and in an easy to manage structure so you are not directly
editing the httpd.conf.  We run the same way and it really hasn''t been
a
problem for low traffic sites.

Each site has it''s own conf file, for example site.conf

<VirtualHost 223.555.555.555>
ServerName my.sites.url
DocumentRoot /home/sites/apache/my_site/www
ProxyPass /some/mongrel/process
php_value upload_max_filesize 32M
php_value post_max_size 32M
php_value memory_limit 32M
php_value max_input_time 180
php_value max_execution_time 180
Alias /pic/ /home/sites/some/directory
Alias /javascript/ /home/sites/some/javascript/
Alias /js/ /home/sites/some/javascript/
php_value include_path
''/home/sites/somesite/lib:/home/sites/otherloc/lib:.''
php_flag register_globals off
php_flag allow_call_time_pass_reference on
php_flag magic_quotes_gpc off
php_value error_reporting 2047
<Files "download.php">
AcceptPathInfo On
</Files>
</VirtualHost>
~

and in your httpd.conf have a line like:

Include /home/sites/apache/*.conf


This will load every .conf file in /home/sites/apache and bingo, there
are your vhosts all tidy.

Hope this helps

Own box through a host provider. Multiple sites on server.

Yep, I found them all.  Thank you. I guess now the problem is the Apache
version.

Re: OT:Mongrel and Apache

This is from the Mongrel site for setting up the proxy:

<VirtualHost *:80>
    ServerName myapp.com
    ServerAlias www.myapp.com

    ProxyPass / http://www.myapp.com:8000/
    ProxyPassReverse / http://www.myapp.com:8000
    ProxyPreserveHost on
  </VirtualHost>

The only thing here is I only want requests to be forward when the
subdomain is called.
So do I leave ServerName and ServerAlias alone ?
The subdomain would be data.myapp.com

Do I put that into Proxy Pass and Reverse ?

TIA
Stuart

Hey Stuart,

Yes, leave the hosts alone, you only want to proxypass and
proxypassreverse for the railsapp related stuff, so, for example, if you 
were going to put the rails app at myapp.com/railsapp your lines would 
look like this:

proxypass / http://localhost:8000  #the port that your mongrel is 
running on
proxypassreverse / http://localhost:8000

should do the trick.

Re: OT:Mongrel and Apache

Sorry, disregard the /railsapp related stuff above, my mind was 
elsewhere, but the proxypass directives should accomplish what you want.

Re: OT:Mongrel and Apache

Proxying from Apache without load balancing somewhere in the mix will give
you relatively poor performance. Tom Mornini commented on this. If Apache
proxies to, say, port 8000 and mongrel is listening on 8000, each request
will have to complete before the next one can be served. Contrast this with
a more typical fcgi or Mongrel cluster setup where there are several Rails
processes any of which can serve a page upon request.

This may not seem like a big deal, but put a little Ajax on your pages and
you *will* be making numerous requests per second. One application instance
will feel pokey. Even if you have to proxy Apache to Pound and have Pound
listen on port 8000, you can then use Pound to do the load balancing among N
Mongrels in a Mongrel cluster. That removes the dependency on a complete
request turnaround.

Anyone? Please correct me if this is incorrect. This is, essentially how my
sites are set up.

Spot on, and good idea to put a balancer after Apache and before
mongrel_cluster. Generally speaking, I like simpler -vs- more  
complex, but
installing a new version of Apache may not quality as simpler in this  
case. :-)

No, but I''m not going to be the one doing it :).
Seriously, though I looked at Pound, not even sure if it would run on this
server.  Earlier version of Redhat,
and what else would surprise me.

Re: OT:Mongrel and Apache

Hi Stuart:

Above posts are correct, you will want to create a Mongrel cluster, not 
just one Mongrel server, or you just won''t be getting your 
top-value-per-dollar. Of course you can''t do that without Apache 2.1 or
later so I would definitely recommend an Apache2 upgrade.

Setting up a Mongrel cluster is outlined at the Mongrel home website. 
Once you''ve done that, here is a sample configuration for Apache2 to 
proxy a subdomain over to that cluster, assuming a local machine Mongrel 
cluster on ports 8000-8002.

<Proxy balancer://mongrel_cluster>
  BalancerMember http://127.0.0.1:8000
  BalancerMember http://127.0.0.1:8001
  BalancerMember http://127.0.0.1:8002
</Proxy>

NameVirtualHost *:80

<VirtualHost *:80>
    DocumentRoot /usr/local/apache2/htdocs/test
    ServerName test.server.com
    ServerAlias test.server.com
    ErrorLog logs/test.server.com-error_log
    CustomLog logs/test.server.com-access_log common
    ProxyRequests Off
    ProxyPass / balancer://mongrel_cluster
    ProxyPassReverse / /balancer://mongrel_cluster
</VirtualHost>

If you wanted to put your application in a folder off the root instead 
of in a subdomain, then you would just put the Proxy lines into the 
default VirtualHost definition in your Apache2 configuration, edited for 
the folder you''re working with. For instance, if you had it in a folder
called "test", then you would have  these directives in your default 
VirtualHost section:

    ProxyRequests Off
    ProxyPass /test balancer://mongrel_cluster
    ProxyPassReverse /test /balancer://mongrel_cluster

In this case you will also need the reverse_proxy_fix plugin from: 
http://www.napcsweb.com/blog/2006/05/10/reverse-proxy-fix-plugin/.

woops - typo - remove the second "/" in that line in both places - 
should be:

     ProxyPassReverse / balancer://mongrel_cluster
