Apache is not serving up the correct page for a sub domain.

twisteguy22 · 08-12-2010, 04:52 PM

hello all.
I have a domain, dns hosted, and apache serving up pages. this all works fine, so far. i even have a cms running.

my confusion starts when i try to host a different site under a subdomain, ie. sub.mydomain.com.

i have two vhosts in apache. one is mydomain.com and the directory is /var/www/mydomain. my domain is a symlink to ~/www

this has worked.

but, when i try to add another vhost like webmail.mydomain.com, and i try to put the root directory in /var/www/webmail, it doesn't work. when i try to access webmail.mydomain.com, i just get the site on mydomain.com.

I feel like i am just missing something really simple here, but i have tried searching around for solutions to no avail.

here are the relevant parts of apache2.conf:

Code:

<VirtualHost *>
DocumentRoot "/var/www/mydomain"
ServerName mydomain.com
<Directory "/var/www/mydomain">
allow from all
Options +Indexes
</Directory>
</VirtualHost>
<VirtualHost *>
DocumentRoot "/var/www/webmail"
ServerName webmail.mydomain.com
<Directory "/var/www/webmail">
allow from all
Options +Indexes
</Directory>
</VirtualHost>

<directory> should have a trailing slash :

Code:

DocumentRoot "/var/www/mydomain"
ServerName mydomain.com
<Directory "/var/www/mydomain/">

and

Code:

DocumentRoot "/var/www/webmail"
ServerName webmail.mydomain.com
<Directory "/var/www/webmail/">

You could also try adding this for each virtual host :

Code:

SetEnv SITE_ROOT /var/www/webmail
SetEnv SITE_HTMLROOT /var/www/webmail

Thanks for the sugestions. I tried what you said, but it didn't seem to make any difference.

Is there anyway that this could be a dns problem?
I have an A record that points mydomain.com to 71.my.ip.7
and I have a cname record that points *.mydomain.com to mydomain.com

anyway the my apache2.conf file looks like this now:

Code:

<VirtualHost *>
DocumentRoot "/var/www/tempest"
ServerName tempesthostingservices.com
<Directory "/var/www/tempest/">
allow from all
Options +Indexes
</Directory>
SetEnv SITE_ROOT /var/www/tempest
SetEnv SITE_HTMLROOT /var/www/tempest
</VirtualHost>

<VirtualHost *>
DocumentRoot "/var/www/webmail"
ServerName webmail.tempesthostingservices.com
<Directory "/var/www/webmail/">
allow from all
Options +Indexes
</Directory>
SetEnv SITE_ROOT /var/www/webmail
SetEnv SITE_HTMLROOT /var/www/webmail
</VirtualHost>

What does the main httpd.conf Document root point to ? It should be pointing to the same place as the first virtual host. This may cause problems if it's pointing to /var/www

Also, all my virtual servers specify the port as in :

Code:

<VirtualHost *:80>

And also, the server name comes before the DocumentRoot directive (in my httpd.conf)
And I have the line :

Code:

RewriteEngine on

just after the DocumentRoot directive.

As for the DNS, it might be worth adding the webmail.domain.com as a separate A record instead of a cname. Point it at the ip address properly. Without that, all you are doing is aliasing webmail.domain.com to domain.com. It needs to be a separate entity. Unless you want to use apache rewriting to send anything with webmail in the address to the correct place.

hmm. switching the order of the name and document root seemed to do something.

when I access the webmail.mydomain.com page i get the mydomain.com page sans the style sheet, not the index.html for the subdomain.

I am using the drupal cms. could this be screwing things up?

I did add an A record.

my http.conf file is completely empty.

here is my apache2 file in full. vhosts are at the bottom.

Code:

#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/apache2/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
ServerRoot "/etc/apache2"

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
#<IfModule !mpm_winnt.c>
#<IfModule !mpm_netware.c>
LockFile /var/lock/apache2/accept.lock
#</IfModule>
#</IfModule>

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.

KeepAliveTimeout 15
