How to Setup a Subdomain with Apache2

1) I am going to assume that you already have Apache2 installed and running properly. If not drop me an email and ill see if I can come up with a how-to on it.

2) Go to /etc/apache2/conf/vhosts and open the vhosts.conf file in your text editor

3) You will need to know all of the DocumentRoot directories of the sub-domains you want to create.

4) Start of by creating a NamedVirtualHost for *:80.

a) At the end of vhosts.conf add a line that says: NamedVirtualHost *:80 and hit enter to go to the next line.

5) Now we will start creating the VirtualHosts. First you will want to create one for www.yourdomain.com.

a) <VirtualHost *:80>
ServerName yourdomian.com
ServerAlias www.yourdomain.com
DocumentRoot /path/to/your/main/DocumentRoot
</VirtualHost>

6) Now we can setup the sub-domains like this:
a) <VirtualHost *:80>
ServerName sub1.yourdomain.com
DocumentRoot /path/to/DocumentRoot/of/sub1
</VirtualHost>

b) <VirtualHost *:80>
ServerName sub2.yourdomain.com
DocumentRoot /path/to/DocumentRoot/of/sub2
</VirtualHost>

c) <VirtualHost *:80>
ServerName sub3.yourdomain.com
DocumentRoot /path/to/DocumentRoot/of/sub2
</VirtualHost>

d) And so on and so on.

7)Now I will try my best to explain Redirects in a nutshell. Redirects are used to redirect something to another page, hence the name Redirect. There are four kinds of Redirects which are, temp, permanent, seeother, and gone. You can find out the descriptions Here. I will use only permanents for this how-to.

Example: Say one your sub-domains in your main DocumentRoot and you want to set it up so that if someone types in www.yourdomain.com/sub1 it will redirect to sub1.yourdomain.com. You would accomplish this by putting a Redirect permanent directive in your main VirtualHost. For this to work right I am pretty sure sub1 has to be in the main DocumentRoot specified above.

a) <VirtualHost *:80>
ServerName yourdomian.com
ServerAlias www.yourdomain.com
DocumentRoot /path/to/your/main/DocumentRoot
Redirect permanent /sub1 http://sub1.yourdomain.com
</VirtualHost>

b) <VirtualHost *:80>
ServerName yourdomian.com
ServerAlias www.yourdomain.com
DocumentRoot /path/to/your/main/DocumentRoot
Redirect permanent /sub1 http://sub1.yourdomain.com
Redirect permanent /sub2 http://sub2.yourdomain.com
</VirtualHost>

8.) Now you can save and close vhosts.conf

9) Next you will want to restart/reload Apache2.

a) /etc/init.d/apache2 restart
b) /etc/init.d/apache2 reload

10) Now go and test to see if your sub-domains work. If not check back here again or try Here.

I made a bash script a long time ago.

the syntax was like this:

wonder -s latex mydomain.com
that would make a subdomain called latex in mydomain.com

but I cant find the script :S - if I find it, I post it here.

EDIT: Woooho... this is post number 999.

you are missing a d in NameVirtualHost *:80 it should read:

Yes its a subdomein from xs4all.

xs4all is a internet provider. And if your nick would be "luckyou"
than luckyou.xs4all.nl directs to your ipadres.

When I remove the # for the line Include conf/vhosts/vhosts.conf
and restart I get this message in the error log:

you can use the first symbolic link /wwwroot but you need to make sure that /wwwroot or whereever it points is owned by apache. i think thats why you get that message.

any idea why djc.gentoowarp.com/anthony.gentoowarp.com doesn't work and vye.gentoowarp.com does?

make sure all of the vhost have *8:80 in them.

also try moving the

Is this the way you said it should look?

I'm pretty sure the *8:80 was a typo, that should be *:80

Then I'm still in the same position, because as you can see the url's ( http://gentoowarp.com/djc and http://gentoowarp.com/anthony ) do not work. But http://gentoowarp.com/vye does? Here is my vhosts again, I have no idea what is causing vye to work but not the others.

alright....compare the groups that each dir is owned by.....make sure they are all the same as in all are owned by apache2 and are part of the same group.

next look in /etc/apache2/conf/commonapache2.conf and see what is defined for vye and not for the rest...in mine i have something along the lines of:
