Rails + Apache2 + Balancer Manager - PHP doesn't work



I have a Debian Server and I managed that Ruby works with Apache2 and
the Balancer Manager that listen to the Mongrel server.

The Problem is that PHP files don’t work anymore.

How do I have to configurate the Balance Manager that PHP is working
again like without the Balance Manager?

Greetings Andi


You are going to have a virtualhost that does not forward all request
to your mongrel… If the request is sent to a mongrel you will ne be
able to render the php file…

SO here are some basics:

DirectoryIndex index.php DocumentRoot "/disk/phpcode"

alias /railscode/javascripts /disk/railscode/public/javascripts
alias /railscode/images /disk/railscode/public/images

<Directory “/disk/phpcode”>
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all

<Directory “/disk/railscode/public”>
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all

<Location “/railscode”>
proxyPass balancer://mongrel/railscode


Hi Freddy

I am operating under ISPConfig, this is my Vhost File:

NameVirtualHost xx.xx.xx.xx:80

RewriteRule .* - [F]

RewriteEngine on
RewriteRule .* - [F]

The ruby projekt is under var/www/web1/
The ruby public is under a symlink var/www/web1/public to
The normal apache is under var/www/web1/web/

Is the error coming from the missing Directory entry?

okay I found an other solution.

I did it the other way around:

ProxyPass /phpBB3 !
ProxyPass / balancer://aekschencluster/ stickysession=JSESSIONID

I set the phpBB3 Forum as an exception.



aaah okay know I know:

<Proxy balancer://aekschencluster>
BalancerMember http://xx.xx.xx.xx:82

<Location /de/>
ProxyPass balancer://aekschencluster/ stickysession=JSESSIONID
#ProxyPassReverse balancer://aekschencluster/de/

With the location tag you define a URL when the proxy should be active.

But my problem is know the link routing from rails because the URL is
now http://www.domain.tdl/de/rubyapplication

But in my Rails application the links route all to the root

What could I do?

Greetings Andi


Depends on the rails backed but if you are using mongrel or thin you
can setup a prefix for the app…

setup a prefix of /app and then in the balancer you use ProxyPass /
