In my server i have to different domains running successfully.
Now I want to define a new subdomain under one of theses domains.

Running apache2ctl –S in order to see Virtual host defined, we get:

apache2: Could not reliably determine the server's fully qualified domain name, using 10.70.220.1 for ServerName
VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:443 www.domain1.org (/etc/apache2/sites-enabled/000-default:59)
*:80 is a NameVirtualHost
default server www.domain1.org (/etc/apache2/sites-enabled/000-default:2)
port 80 namevhost www.domain1.org (/etc/apache2/sites-enabled/000-default:2)
port 80 namevhost subx.domain1.org (/etc/apache2/sites-enabled/000-default:48)
port 80 namevhost www.domain2.org (/etc/apache2/sites-enabled/000-default:54)
Syntax OK

It looks like virtual host are ok. When I try to browse to domain1.org or domain2.org everything is ok. The problem is when I try to brose to subdomain subx.domain1.org. This subdomain is not working properly.

I´m sure something is missing but I don’t know what.

Server version: Apache/2.2.3
Server built: Sep 8 2008 09:03:05

Thanks

Please define what you mean by "is not working properly".
Apache config looks good, so it could be a dns issue, but without further details it's difficult to guess

The error is in any browser: Page Not Found or IE cant show the page.

So you get a 404 (not found) error. What's in apache error_log?

Error logs contains the folowing:

Huh, I don't see any reference to subx.domain1.org in these logs. You should post the logs related to the not working subdomain.
Or add:
inside the subx.domain1.org vhost container, so it creates its own logs, restart apache and test. And post here the subx-error.log.

I did the change suggested by you. Then restarted apache & try to browse to this subdomain. Result: the subx-error.log was created but is empty.

<VirtualHost *:80>
ServerName subx.domain.org
DocumentRoot /var/www/subx
ErrorLog /var/log/apache2/error_esc.log

# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
ServerSignature Off
</VirtualHost>

So you say that you visit http://subx.domain.org, you get a 404 error and you get nothing logged!
Are you sure you're visiting the right vhost? What gives
And what happens if you visit http://www.domain1.org/subx

nslookup subx.domain.org

Server: 190.9.128.11
Address: 190.9.128.11#53

** server can't find subx.domain.org: NXDOMAIN

If I visit http://www.domain1.org/subx the browser redirect to http://www.domain1.org

So your dns knows nothing about your new subdomain. You need to add an A record pointing to the IP address of your apache server


That shouldn't happen according to your apache config, but anyway if your new vhost works after the dns changing, I guess it will stop.

Do you know how can i add an A record pointing to the IP address?

Thanks

Yeah I know. The admin of the nameserver that is authoritative for domain.org must add
(x.x.x.x is the IP of your apache), in the domain.org zone file, increase the serial number and reload the dns server.
