How to configure apache to use ipv6 for subdomains - apache

I have just setup a website using a domain like domain.com. And then setup another website sub.domain.com.
Now both of them can be visited via ipv4. And then I added the ipv6 address[a:b::c:d]. However, when I restarted httpd service, the following message appeared:
[warn] VirtualHost a:b::c:d:80 overlaps with VirtualHost a:b::c:d:80,
the first has precedence, perhaps you need a NameVirtualHost
directive.
I can now only visit domain.com via ipv6, not sub.domain.com. But, somehow, I can visit domain.com/sub via ipv6. I seems that ipv6 address cannot be treated like ipv4 address in apache. I am wondering how could I configure the apache to behave as what I wish.
I have the following lines in my httpd.conf file:
Listen 1.2.3.4:80
Listen [a:b::c:d]:80
<VirtualHost 1.2.3.4:80>
DocumentRoot /var/www/html
ServerName domain.com
ErrorLog "/var/www/logs/error.log"
CustomLog "/var/www/logs/access.log" common
</VirtualHost>
<VirtualHost [a:b::c:d]:80>
DocumentRoot /var/www/html
ServerName domain.com
ErrorLog "/var/www/logs/ipv6_error.log"
CustomLog "/var/www/logs/ipv6_access.log" common
</VirtualHost>
<VirtualHost 1.2.3.4:80>
DocumentRoot /var/www/html/sub
ServerName sub.domain.com
ErrorLog "/var/www/logs/sub_error.log"
CustomLog "/var/www/logs/sub_access.log" common
</VirtualHost>
<VirtualHost [a:b::c:d]:80>
DocumentRoot /var/www/html/sub
ServerName sub.domain.com
ErrorLog "/var/www/logs/sub6_error.log"
CustomLog "/var/www/logs/sub6_access.log" common
</VirtualHost>

Just as Jeremy Visser mentioned, I searched the config file and found the following line:
NameVirtualHost 1.2.3.4:80
It seems that this is the problem. Then I added this line:
NameVirtualHost [a:b::c:d]:80
The problem was settled!

How to set up Apache with 3 sites: Two name based virtual hosts and one via the IP address

I have 2 sites linked to domains already.
For this I have 2 conf files into /etc/apache2/sites-available/:
<domain1>.conf
<domain2>.conf
With DocumentRoot /var/www/domain1 and DocumentRoot /var/www/domain2.
In addition, I need to setup the 3rd site direct linked to server IP.
For this I created conf file:
IP.conf (IP is IP of the server):
<VirtualHost *:80>
ServerAdmin <email>
ServerName <IP>
ServerAlias <IP>
DocumentRoot /var/www/html/wordpress
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Run:
sudo a2ensite <IP>.conf
And:
restart apache service.
But it doesn't help.
Could you advise how to configure routing?
The issue is the default Apache config always uses the IP address of the server. So that IP.conf will never be loaded.
You need to edit the default Apache config — located in sites-available — to make your changes.
Looking at your config, you are indicating the raw IP address for the ServerName and ServerAlias that will — effectively — defeat the purpose of setting up name based virtual hosts:
<VirtualHost *:80>
ServerAdmin <email>
ServerName <IP>
ServerAlias <IP>
DocumentRoot /var/www/html/wordpress
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
What happens in a case like this is the configs will be ignored because the default Apache setup will always defer to the IP address of the machine you are on. Heck, it would even use all network interfaces if your server has multiple IP addresses.
For name based virtual hosting to work, you must use the domain/host name in your config. Something like this for domain1:
<VirtualHost *:80>
ServerAdmin <email>
ServerName <domain1>
ServerAlias <domain1>
DocumentRoot /var/www/domain1
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
And this for domain2
<VirtualHost *:80>
ServerAdmin <email>
ServerName <domain2>
ServerAlias <domain2>
DocumentRoot /var/www/domain2
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Now for the IP address host config, you should go into your Apache config directory — /etc/apache2/ on Debian/Ubuntu or /etc/httpd/ on CentOS/RedHat — and look inside the sites-available directory. There should be a file named 000-default.conf:
/etc/apache2/sites-available/000-default.conf
And make the changes you are showing in your IP.conf in there. At a most basic level just change the DocumentRoot to be this:
DocumentRoot /var/www/html/wordpress
Then restart Apache and it should be working as expected.

Apache IP Virtual Hosts

Server has two IPs, fresh centos min install. Apache is working, both ips load Apache test page. both www.domain.com and domain.com resolve to second IP.
I'd like for the first IP (192.168.0.1) to load Apache test page, this is working fine
I want the second IP (192.168.0.2) to load a website in /home/site/www
Currently when we goto domain.com or www.domain.com or 2nd IP it loads apache test page instead of the site, here's our config. Also I have the IPs listed as 192 instead of the real ips. What am I missing? Why isn't 192.168.0.2 loading /home/site/www instead of the Apache test page?
ServerRoot "/etc/httpd"
Listen 80
ServerName 192.168.0.1:80
DocumentRoot "/var/www/html"
<Directory "/var/www/html">
NameVirtualHost 192.168.0.2:80
<VirtualHost 192.168.0.2:80>
DocumentRoot /home/site/www
ServerName mydomain.com
ServerAlias *.mydomain.com
ErrorLog logs/mydomain.com-error_log
CustomLog logs/mydomain.com-access_log common
</VirtualHost>
Update
The Fix
chcon -R --reference=/var/www /home/site/www
SELinux needed the correct permissions set on it, using the reference it copies the same permissions to my new folder
Try this:
ServerRoot "/etc/httpd"
Listen 80
ServerName 192.168.0.1:80
NameVirtualHost 192.168.0.1:80
NameVirtualHost 192.168.0.2:80
<VirtualHost 192.168.0.1:80>
DocumentRoot /var/www/html
ServerName mydomain.com #change accordingly
ServerAlias *.mydomain.com
ErrorLog logs/mydomain.com-error_log
CustomLog logs/mydomain.com-access_log common
</VirtualHost>
<VirtualHost 192.168.0.2:80>
DocumentRoot /home/site/www
ServerName mydomain2.com
ServerAlias *.mydomain2.com
ErrorLog logs/mydomain2.com-error_log
CustomLog logs/mydomain2.com-access_log common
</VirtualHost>
Don't forget to apply the changes on apache.
service httpd reload or similar command.
Also, make sure the directory /var/www/html has, at least, reading permissions for the apache user.
You are missing the NameVirtualHost directive.
NameVirtualHost 192.168.0.2:80
I would also highly suggest putting in Directory directives in as well.

Strange problem with Apache Virtual Hosts

I have recently installed Apache 1.3.41 on a Windows Vista machine. I have not changed the default settings in httpd.conf aprart from trying to setup virtual hosts, as follows:
Added some host names in the hosts file:
127.0.0.1 localhost
#::1 localhost
127.0.0.1 mysite
127.0.0.1 mydomain
I made the following folders in C:/Users/Moukasp/
C:/Users/Moukasp/Apache
C:/Users/Moukasp/django/mysite
Then added some simple html pages in each of those folder and the c:/Users/Moukasp/pictures folder and, finally, I added the following settings at the end of httpd.conf:
NameVirtualHost 127.0.0.1
<VirtualHost localhost>
# ServerAdmin webmaster#dummy-host.example.com
DocumentRoot "C:/Users/Moukasp/Apache"
ServerName localhost
Alias "/pics" "c:/users/moukasp/pictures"
Alias "/ap" "C:/Program Files/Apache Group/Apache/htdocs"
Alias "/dj" "C:/Users/Moukasp/django/mysite"
# ErrorLog logs/dummy-host.example.com-error_log
# CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost mysite>
# ServerAdmin webmaster#dummy-host.example.com
DocumentRoot "C:/Users/Moukasp/django/mysite"
ServerName mysite
# ErrorLog logs/dummy-host.example.com-error_log
# CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost mydomain>
# ServerAdmin webmaster#dummy-host.example.com
DocumentRoot "C:/Users/Moukasp/django/mysite"
ServerName mydomain
# ErrorLog logs/dummy-host.example.com-error_log
# CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
So, urls
http://localhost
http://localhost/pics
http://localhost/ap
http://localhost/dj
http://mydomain
work fine. But I there's no response from http://mysite which, as can be seen from the settings, serves from the same folder as http://mydomain. I have tried various names but no response. The hosts file is being read every time I start the Apache server. I even removed the mydomain server from the hosts file and the httpd.conf lest there's a limitation in the number of virtual hosts, but no luck.
Any help would be greatly appreciated, els I go mad! It is true, I have being trying this after complete failure to make Apache work with mod_python for django! I just hoped that a step at a time would lead to some success!
Try:
NameVirtualHost 127.0.0.1:80
In your httpd.conf. My config file includes a comment stating a port-specifier should be used.
The VirtualHost and NameVirtualHost directives should have IP addresses and ports:
NameVirtualHost 127.0.0.1:80
<VirtualHost 127.0.0.1:80>
# ServerAdmin webmaster#dummy-host.example.com
DocumentRoot "C:/Users/Moukasp/django/mysite"
ServerName mysite
# ErrorLog logs/dummy-host.example.com-error_log
# CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
Tried NameVirtualHost 127.0.0.1:80 but it doesn't make any difference! The only servers that work are localhost and mydomain.
I wonder whether I need to do something more than just declare the server name of each virtual host in the hosts file.
Try adding a port declaration to the hosts. For example:
<VirtualHost mydomain:80>
DocumentRoot "C:/Users/Moukasp/django/mysite"
ServerName mydomain
</VirtualHost>

htaccess Domain Simulation

I have a server that hosts stuff automatically from /var/www. I copied a directory like domain.com inside /var/www. I then added domain.com into my /etc/hosts for 127.0.0.1 (localhost/loopback). What's the .htaccess trick with Apache so that I can hit my site with: http://domain.com/ and it automatically knows to look in /var/www/domain.com/ (without redirection of the URL)?
You need a virtual host like this:
NameVirtualHost *:80
<VirtualHost *:80>
DocumentRoot /var/www/domain.com/
ServerName domain.com
</VirtualHost>
More information on the Apache documentation: http://httpd.apache.org/docs/2.0/vhosts/examples.html
I think you are looking for:
<VirtualHost *:80>
ServerAdmin mail#domain.com
DocumentRoot /var/www/htdocs/domain.com/
ServerName *.domain.com
ErrorLog logs/domain-error_log
CustomLog logs/domain-access_log common
</VirtualHost>
this will look for anything comming in on *:80 and if it's domain.com its DocRoot becomes /var/www/htdocs/domain.com

Why does http://localhost redirect to my default virtual host once I setup virtual hosts in Apache?

This is probably an easy question, but I want to understand better how Apache works with virtual hosts. I am setting up virtual hosts because I work on multiple websites at once and I don't want to use subdirectories. I was pretty much using the default Apache httpd.conf file with the DocumentRoot pointing to something like "/www". I uncommented the virtual hosts include and added the following:
NameVirtualHost *:80
<VirtualHost *:80>
ServerName site1.dev
DocumentRoot /www/site1
</VirtualHost>
<VirtualHost *:80>
ServerName site2.dev
DocumentRoot /www/site2
</VirtualHost>
Now when I go to http://localhost I get the default page for site1.
I'm sure there is a reason why this makes sense, but I don't quite understand it. I would've thought that only requests that were explicitly to http://site1.test would get routed through that directive and it wouldn't just become the default. Can someone explain why it becomes the default.
http://httpd.apache.org/docs/1.3/vhosts/name-based.html
(Should be true for 2.x also)
"If no matching virtual host is found, then the first listed virtual host that matches the IP address will be used.
As a consequence, the first listed virtual host is the default virtual host. The DocumentRoot from the main server will never be used when an IP address matches the NameVirtualHost directive. If you would like to have a special configuration for requests that do not match any particular virtual host, simply put that configuration in a container and list it first in the configuration file."
answer 1 is correct
and i'd add with namevirtualhosts as the first entry
essentially matches any not-named elsewhere virtualhost
it should ONLY be used to catch unintentional mal-formed and broken traffic
ie a machene with one ip called john.domain.com running www.domain.com and www.domain2.com as valid webservers on ip www.xxx.yyy.zzz might have an optimal config like thus
<VirtualHost *:80>
DocumentRoot /var/webserver/static-sites/unknown/
# a directory readable by apache with only a robots.txt denying everything
ServerName bogus
ErrorDocument 404 "/errordocuments/unknown-name.html"
#custom 404 describing how/what they might have done wrong try pointing a browser {with a hosts file at http://bogus/ on 193.120.238.109 to see mine#
ErrorLog /var/log/httpd/unknown-error.log
CustomLog /var/log/httpd/unknown-access.log combined
</VirtualHost>
<VirtualHost *:80>
DocumentRoot /var/webserver/static-sites/unknown/
# a possibly different directory readable by apache with only a robots.txt denying everything
ServerName www.xxx.yyy.zzz
ServerAlias john.domain.com
ErrorDocument 404 "/errordocuments/ip-name.html"
ErrorDocument 403 "/errordocuments/ip-name.html"
#custom 404 telling them as a likely hacker/bot you wish to have nothing to do with them see mine at http://193.120.238.109/
ErrorLog /var/log/httpd/ip-error.log
CustomLog /var/log/httpd/ip-access.log combined
</VirtualHost>
<VirtualHost *:80>
ServerName domain.com
RedirectPermanent / http://www.domain.com/
ErrorLog logs/www.domain.com-error.log
CustomLog logs/www.domain.com-access.log combined
</VirtualHost>
<VirtualHost *:80>
DocumentRoot /var/webserver/ftpusers/domain
ServerName www.domain.com
ServerPath /domain
ErrorLog logs/www.domain.com-error.log
CustomLog logs/www.domain.com-access.log combined
</VirtualHost>
<VirtualHost *:80>
ServerName domain2.com
RedirectPermanent / http://www.domain2.com/
ErrorLog logs/www.domain2.com-error.log
CustomLog logs/www.domain2.com-access.log combined
</VirtualHost>
<VirtualHost *:80>
DocumentRoot /var/webserver/ftpusers/domain2
ServerName www.domain2.com
ServerPath /domain2
ErrorLog logs/www.domain2.com-error.log
CustomLog logs/www.domain2.com-access.log combined
</VirtualHost>
Confirming that for Apache 2.x, the first virtual host (with the same port number) will be used if a matching virtual host is not found.
http://httpd.apache.org/docs/2.2/vhosts/details.html
"If no matching vhost could be found the request is served from the first vhost with a matching port number that is on the list for the IP to which the client connected"
You can always add this code below, put it right below NameVirtualHost *:80 so that your default document root is served by default if no other virtual hosts found.
<VirtualHost *:80>
ServerName localhost
DocumentRoot /my/default/document/root
</VirtualHost>
Simply put this code at top in httpd-vhosts.conf
<VirtualHost localhost:80>
ServerName localhost
DocumentRoot d:/xampp/htdocs
<Directory "d:/xampp/htdocs/">
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Require local
</Directory>
</VirtualHost>
One way to do this is:
In your VirtualHosts configuration, enter the specific local site name you want to enable instead of using a wildcard:
<VirtualHost site1.dev:80> instead of <VirtualHost *:80>
Switch off NameVirtualHost *:80 which can be done by commenting it out in your vhosts.conf file
In your /etc/hosts file mention both aliases for the loopback IP:
127.0.0.1 localhost site1.dev
That's it. You should see that localhost goes to the default DocumentRoot as usual and the site1.dev goes to the site you've setup as virtual host.
