I'm trying to do something slightly different than is described in the Apache
documentation that I've read. We have an internal Linux server that uses
Apache as a load-balancer + URL redirector to a Redmine instance running a Thin
web server on localhost ports 3000-3002. We have a "redmine" alias that we are
load balancing among these 3 ports with the following VirtualHost entry:
<VirtualHost *>
ServerAdmin [email protected]
ServerName sdlcdevbal832
ServerAlias redmine
RewriteEngine On
# Redirect all non-static requests to cluster
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ balancer://redminecluster%{REQUEST_URI} [P,QSA,L]
</VirtualHost>
<Proxy balancer://redminecluster>
BalancerMember http://127.0.0.1:3000
BalancerMember http://127.0.0.1:3001
BalancerMember http://127.0.0.1:3002
</Proxy>
However, we also have a separate test Redmine instance running on port 4000.
We created a "redminetest" alias and we want all URLs that start with
"http://redminetest"; to be redirected to port 4000 (no load balancing) while
URLs that start with "http://redmine"; to continue to be load-balanced on ports
3000-3002. We created the following additional VirtualHost entry:
<VirtualHost *>
ServerAdmin [email protected]
ServerName sdlcdevbal832
ServerAlias redminetest
RewriteEngine On
# Redirect all non-static requests to cluster
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ balancer://redminetestcluster%{REQUEST_URI}
[P,QSA,L]
</VirtualHost>
<Proxy balancer://redminetestcluster>
BalancerMember http://127.0.0.1:4000
</Proxy>
Unfortunately, this did not work. It resulted in URLs with both the "redmine"
and "redminetest" aliases being sent to the load-balanced production instance.
Can somebody explain what we are doing wrong ? The Apache documentation isn't
clear about how the server matches VirtualHost entries and we've obviously done
something wrong. Any help would be greatly appreciated. Thanks.
