Question

I’m playing about with lighttpd on a small virtual private server. I two domains pointing to the server. I am using the latest version of lighttpd and mod_evhost on Ubuntu 8.10.

1. I’m trying to set up a rule such that if anyone requests domain.com or http://www.domain.com they get served from /webroot/domain.com/www/

2. Similarly, if anyone requests sub.domain.com they get served from /webroot/domain.com/sub/

3. If people requests fake.domain.com (where /webroot/domain.com/fake/ does not exist) I would like them served from /webroot/domain.com/www/

The third requirement isn’t quite so important, I can deal with people requesting subdomains that don’t exist being served from the server document root of /webroot/server.com/www/ even if they requested fake.domain.com

I’ve included the relevant parts of my lighttpd.conf file below:

server.document-root = '/webroot/server.com/www/'  // regex to match sub.domain.com $HTTP['host'] =~ '\b[a-zA-Z]\w*\.\b[a-zA-Z]\w*\.\b[a-zA-Z]\w*' {     evhost.path-pattern = '/webroot/%0/%3/'     }  // regex to match domain.com     $HTTP['host'] =~ '\b[a-zA-Z]\w*\.\b[a-zA-Z]\w*' {     evhost.path-pattern = '/webroot/%0/www/'     } 

So where am I going wrong? At the moment, all requests to *.domain.com and domain.com are being served from /webroot/domain.com/www/

I’d appreciate any help you guys could offer and if I’ve left anything relevant out please tell me!

Cheers, Rob

Your regexes seem to be a bit overdone.

Here is what I would use:

// regex to match sub.domain.com $HTTP['host'] =~ '^[^.]+\.[^.]+\.[^.]+$' {     evhost.path-pattern = '/webroot/%0/%3/'     }  // regex to match domain.com     $HTTP['host'] =~ '^[^.]+\.[^.]+$' {     evhost.path-pattern = '/webroot/%0/www/'     } 

where:

[^.]+ matches anything but a dot, 1..n times 

To match only valid sub domains with fall back to ‘www’, you can use this:

// default: route everything to 'www' $HTTP['host'] =~ '([^.]+\.)?domain\.com$' {     evhost.path-pattern = '/webroot/%0/www/' }  // specific regex overwrites 'path-pattern' for valid sub-domains only $HTTP['host'] =~ '^(valid1|valid2|sub)\.domain\.com$' {     evhost.path-pattern = '/webroot/%0/%3/'     }
