How to add Apache 301 redirect to VirtualHost in Apache

Sunday, September 25th, 2011

I’ve had two domain names which were pointing to the same website content.
As one can read in any SEO guide around this is a really bad practice as search engines things automatically there is a duplicate site content and this has automatically a negative effect on the site pagerank.
To deal with situation where multiple domains are pointing to the same websites its suggested by many SEO specialists that a 301 redirect is created from all the domain websites to a single website domain which will open the actual website.

Making the 301 direct domain from the sample domain my-redirect-domain.com to www.mydomain.com can be done with a virtualhost dfefinition in either httpd.conf or with the respective file containing the domain virtualhost definitions:
Here is the exact VirtualHost code I use to make a 301 redirect.

<VirtualHost *>  ServerAdmin support@mydomain.com  ServerName my-redirected-domain.com
ServerAlias my-redirected-domain.com www.my-redirected-domain.com
RewriteEngine on RewriteRule ^/(.*) http://www.mydomain.com/$1 [L,R=301]
</VirtualHost>

After placing the VirtualHost redirect, an apache redirect is required.
Further on when a Gooogle or Yahoo Bot visits the website and does any request to my-redirect-domain.com or www.my-redirect-domain.com , they will be redirected with a 301 reuturned code to www.mydomain.com

This kind of redirect however can have a negative impact on the Apache CPU use (performance), especially if the my-redirect-domain.com is high traffic domain. This is because the redirect is done with mod_rewrite.

Therefore it might be better on high traffic domains to create the mod_rewrite redirect by using a vhost like:

<VirtualHost *>
ServerAdmin support@mydomain.com
ServerName my-redirected-domain.com
Redirect 301 / http://www.mydomain.com/
</VirtualHost>

The downside of using the Apache 301 redirect capabilities like in the above example is that any passed domain urls like let’s say http://www.my-redirected-domain.com/support/ would not be 301 redirected to http://www.mydomain.com/support/ but instead the redirect will be done straight to http://www.mydomain.com/

Installing the phpbb forum on Debian (Squeeze/Sid) Linux

howto-easily-install-phpbb-on-debian-gnu-linux

I've just installed the phpbb forum on a Debian Linux because we needed a goodquick to install communication media in order to improve our internal communication in a student project in Strategic HR we're developing right now in Arnhem Business School.

Here are the exact steps I followed to have a properly it properly instlled:

1. Install the phpbb3 debian package
This was pretty straight forward:

debian:~# apt-get install phpbb3

At this point of installation I've faced a dpkg-reconfigure phpbb deb package configuration issue:
I was prompted to pass in the credentials for my MySQL password right after I've selected the MySQL as my preferred database back engine.
I've feeded my MySQL root password as well as my preferred forum database name, however the database installation failed because, somehow the configuration procedure tried to connect to my MySQL database with the htcheck user.
I guess this has to be a bug in the package itself or something from my previous installation misconfigured the way the debian database backend configuration was operating.
My assumption is that my previously installed htcheck package or something beforehand I've done right after the htcheck and htcheck-php packages installation.

after the package configuration failed still the package had a status of properly installed when I reviewed it with dpkg
I've thought about trying to manually reconfigure it using the dpkg-reconfigure debian command and I gave it a try like that:

debian:~# dpkg-reconfigure phpbb3

This time along with the other fields I've to fill in the ncurses interface I was prompted for a username before the password prompted appeared.
Logically I tried to fill in the root as it's my global privileges MySQL allowed user.
However that didn't helped at all and again the configuration tried to send the credentials with user htcheck to my MySQL database server.
To deal with the situation I had to approach it in the good old manual way.

2. Manually prepare / create the required phpbb forum database

To completet that connected to the MySQL server with the mysql client and created the proper database like so:

debian:~# mysql -u root -p
mysql>
CREATE database phpbb3forum;

3. Use phpmyadmin or the mysql client command line to create a new user for the phpbb forum

Here since adding up the user using the phpmyadmin was a way easier to do I decided to go that route, anyways using the mysql cli is also an option.

From phpmyadmin It's pretty easy to add a new user and grant privileges to a certain database, to do so navigate to the following database:

Privileges -> -> Add a new user ->

Now type your User name: , Host , Password , Re-type password , also for a Host: you have to choose Local from the drop down menu.

Leave the Database for user field empty as we have already previously created our desired database in step 2 of this article

Now press the "Go" button and the user will get created.

Further after choose the Privileges menu right on the bottom of the page once again, select through the checkbox the username you have just created let's say the previously created user is phpbb3

Go to Action (There is a picture with a man and a pencil on the right side of this button

Scroll down to the page part saying Database-specific privileges and in the field Add privileges on the following database: fill in your previosly created database name in our case it's phpbb3forum

and then press the "Go" button once again.
A page will appear where you will have to select the exact privileges you would like to grant on the specific selected database.
For some simplicity just check all the checkbox to grant as many privilegs to your database as you could.
Then again you will have to press the "Go" button and there you go you should have already configured an username and database ready to go with your new phpbb forum.

4. Create a virtualhost if you would like to have the forum as a subdomain or into a separate domain

If you decide to have the forum on a separate sub-domain or domain as I did you will have to add some kind of Virtualhost into either your Apache configuration /etc/apache2/apache2.conf or into where officially the virutualhosts are laid in Debian Linux in /etc/apache2/sites-available
I've personally created a new file like for instance /etc/apache2/sites-available/mysubdomain.mydomain.com

Here is an example content of the new Virtualhost:

<VirtualHost *>
ServerAdmin admin-email@domain.com
ServerName mysubdomain.domain.com

# Indexes + Directory Root.
DirectoryIndex index.php index.php5 index.htm index.html index.pl index.cgi index.phtml index.jsp index.py index.asp

DocumentRoot /usr/share/phpbb3/www/

# Logfiles
ErrorLog /var/log/apache2/yourdomain/error.log
CustomLog /var/log/apache2/yourdomain/access.log combined
# CustomLog /dev/null combined
<Directory /usr/share/phpbb3/www/>
Options FollowSymLinks MultiViews -Includes ExecCGI
AllowOverride All
Order allow,deny
allow from all </Directory>
</VirtualHost>

In above Virtualhost just change the values for ServerAdmin , ServerName , DocumentRoot , ErrorLog , CustomLog and Directory declaration to adjust it to your situation.

5. Restart the Apache webserver for the new Virtualhost to take affect

debian:~# /etc/init.d/apache2 restart

Now accessing your http://mysubdomain.domain.com should display the installed phpbb3 forum
The default username and password for your forum you can use straight are:

username: admin
password: admin

So far so good you by now have the PHPBB3 forum properly installed and running, however if you try to Register a new user in the forum you will notice that it's impossible because of a terrible ugly message reading:

Sorry but this board is currently unavailable.

I've spend few minutes online to scrape through the forums before I can understand what I have to stop that annoying message from appearing and allow new users to register in the phpbb forum

The solution came natural and was a setting that had to be changed with the forum admin account, thus login as admin and look at the bottom of the page, below the text reading Powered by phpBB © 2000, 2002, 2005, 2007 phpBB Group you will notice a link with Administration Control Panel
just press there a whole bunch of menus will appear on the screen allowing you to do numerous things, however what you will have to do is go to
Board Settings -> Disable Board

and change the radio button there to say No

That's all now your forum will be ready to go and your users can freely register and if the server where the forum is installed has an already running mail server, they will receive an emails with a registration data concerning their new registrations in your new phpbb forum.
Cheers and Enjoy your new shiny phpbb Forum 🙂
