i am the owner of the server

i want to create 1000 domains at time

one by one will be a lengthy task

so i suppose to do this

@MrCoderOct 17.2007 — #Include files in to your httpd.conf file that you have created using php.

Great care should be taken when working on something like this thou.

Please take on board Bokeh's warning.

Lots of packages, mainly back end website hosting software, will allow the server to reconfigure vhost's. It is something that could be dangerous it you allowed any of your scripts to be executed by visitors to your site.

Second, since the webserver runs as "[I]nobody[/I]", if it could edit the config file, so could any other process running on the same machine, (maybe external ones too).

Third, having 1000's of v-hosts is not a very clever idea as far as resources, descriptors, etc are concerned and just to load the server config will consume several hundred megabytes of RAM and take forever.

I recommend a different approach that neither requires modification of the config file nor does it call for a server restart for the changes to take effect. The following code would be the first (and maybe the only) virtual host in your httpd.conf file:

[CODE]<VirtualHost *:80>
 ServerName default
 <IfModule mod_rewrite.c>
 RewriteEngine on
 # grab the hostname, ignore the www
 RewriteCond %{HTTP_HOST} ^(www.)?(.+)$ [NC]
 RewriteRule !^/*(icons|cgi-bin)(/?|/.+)$
 /root/apache2/htdocs/%2/public%{REQUEST_URI} [L,NC]
 </IfModule>
 DocumentRoot /root/apache2/htdocs
 php_admin_value open_basedir /root/apache2/htdocs;/root/php/temp
 php_admin_value upload_tmp_dir /root/php/temp
 php_admin_value auto_prepend_file /root/apache2/htdocs/php-prepend.php
 </VirtualHost>[/CODE]

This points "[I]http://www.domain.com/subdirectory/file.php[/I]" to "[I]/root/apache2/htdocs/domain.com/public/subdirectory/file.php[/I]".

There is a small issue [I]document root[/I] being out of sync with the domain document root and this is corrected with a prepended file placed at "[I]/root/apache2/htdocs/php-prepend.php[/I]". The contents of that file would be:

[code=php]<?php
 
 $_SERVER['DOCUMENT_ROOT'] = substr($_SERVER['SCRIPT_FILENAME'], 0, strlen($_SERVER['SCRIPT_FILENAME'])-strlen($_SERVER['PHP_SELF']));
 
 ?>[/code]

Ok, now you've done that all you need to do (on the webserver front) to add a new domain is add a directory tree for each domain inside your htdocs directory.

@MrCoderOct 17.2007 — #Very nice bokeh!

Would that kind of catch all domain system need declaring after the other real domains in the vhost file?

Is there any kind of security hole when using something like this?

@bokehOct 17.2007 — #Very nice bokeh!

Is there any kind of security hole when using something like this?[/QUOTE]The biggest problem is that it is the directory structure is traversable back to wherever your open base directory boundary is (if you bother with one). This is because it is not possible to make the boundary dynamic from the vhost (except if you do a mod to the PHP source code) meaning the is one boundary is used by all domains. The open base directory restriction is a band-aid measure anyway and ideally this should be handled by your *nix permissions. On a dedicated server though none of that is of much importance because there aren't other users that might try to access each others files.

@MrCoderOct 17.2007 — #A perfect solution to the problem!

Get WebMin. It has a [b]VirtualMin[/b] module which has a batch option to create your 1000 domains, done by importing a file. The basic application is free.

All this hokey-pokey with the config files is a disaster in waiting...
