CF file not found with Apache virtual hosts - apache

Question

I have Apache 2.2 configured to run with Coldfusion 9.2, both on the same Centos 6.2. The general config of DocumentRoot in Apache is
DocumentRoot "/var/www/html"
Up until now Apache handed all calls to cfcs and cfms over to Coldfusion. I then created a virtual host
<VirtualHost 192.168.123.207:80>
ServerName myserver.server.private
ServerAlias www.myserver.server.private
ServerAlias webmail.myserver.server.private
ServerAlias admin.myserver.server.private
DocumentRoot /home/myserver/public_html
ErrorLog /var/log/virtualmin/myserver.server.private_error_log
CustomLog /var/log/virtualmin/myserver.server.private_access_log combined
ScriptAlias /cgi-bin/ /home/myserver/cgi-bin/
DirectoryIndex index.html index.htm index.php index.php4 index.php5
<Directory /home/myserver/public_html>
Options +Indexes +IncludesNOEXEC +SymLinksIfOwnerMatch

</Directory>
<Directory /home/myserver/cgi-bin>
allow from all
AllowOverride All
Options=ExecCGI,Includes,IncludesNOEXEC,Indexes,MultiViews,SymLinksIfOwnerMatch
</Directory>
RewriteEngine on
RewriteCond %{HTTP_HOST} =webmail.myserver.server.private
RewriteRule ^(.*) http://myserver.server.private:20000/ [R]
RewriteCond %{HTTP_HOST} =admin.myserver.server.private
RewriteRule ^(.*) http://myserver.server.private:10000/ [R]
</VirtualHost>
When I open a html file on http://myserver.server.private/hello.html, the correct file within the virtual host document root (/home/myserver/public_html) gets served.
Calling a cfm fails though. Apache passes the request on correctly but then a Coldfusion error message shows up:
File not found: /hello.cfm
It seems that Coldfusion is getting the file name, prefixes a wrong directory path to it and fails loading it from the disk.
I scanned all Coldfusion files for a wrong document root but could not find anything.
EDIT
It turns out that Coldfusion looks into it's own webroot directory at
/opt/coldfusion/wwwroot
I placed a file with the same name but different content there and that one gets served, although there is a) a virtual host and b) the general DocumentRoot is set to /var/www/html.

Answer 1

It turns out that the coldfusion user (cfusion in my case) needs to be in the group of the virtual host user.
usermod -a -G newuser cfusion
After a restart of coldfusion, all works.
