I have recently been looking around at peoples problems with Apache, and the most common problem I notice is multiple virtual hosts on one single server.
I will give a very simple, and thorough tutorial below, which I hope should enlighten simple problems which nobody has addressed.
Before we start i am assuming the following:
* You are running Ubuntu 11.04.
* You are installing Apache2.
* You have two domain names pointed to your DNS/IP addresses.
Now let's start off by installing Apache2.
This will install apache2 on the server inside the /etc/apache2 directory.
sudo apt-get install apache2
And now all you want to do is have the following:
* and so on?
Well first of all i suggest the following:
* /var/www/domain1.com/dev/ -> Development site!
* /var/www/domain1.com/stage/ -> Staging / UAT
* /var/www/domain1.com/logs/ -> Logs from apache/php etc.
* /var/www/domain1.com/prod/ -> Live/Production site (doc root)
* /var/www/domain1.com/prod/cgi-bin/ -> CGI Dir for live site!
Now when you enter "www.domain.com" this will goto the /var/www/domain1.com/prod/ directory! you can then set-up sub-domains and HTTP authenticate them to restrict access to your development and staging environments.
Anyway, let's create our site directories.
After the directories are created, create 2 index files (for testing purposes).
sudo mkdir /var/www/domain1.com /var/www/domain1.com/dev /var/www/domain1.com/stage /var/www/domain1.com/prod /var/www/domain1.com/logs
Entire some text, and save this (so you know it website 1).
sudo vi /var/www/domain1.com/prod/index.htm
Repeat this step replacing domain1.com to your second domain name.
Right, now we just need to get Apache to work, first I will explain the common error people are faced with,
normally an error something along the lines of "NameVirtualHost *:80 has no Virtual Hosts" this is a quick fix.
And you see this line:
sudo vi /etc/apache2/ports.conf
Make this look like...
Simply removing the ":80" from the end of that one line.
And now you need to set-up your apache config per site, using the site-availabled and sites-enabled.
first goto your sites-available and...
delete the contents and replace with the following...
sudo cp default domain1.co.uk
And save this file. Then copy this file for domain2.com/.co.uk
# Indexes + Directory Root.
DirectoryIndex index.html index.php
# CGI Directory
ScriptAlias /cgi-bin/ /var/www/domain1.com/prod/cgi-bin
CustomLog /var/www/domain1.co/logs/access.log combined
After this, you need to enable them, using symlinks, despite apache having features for this,
allow me to show you the correct way of sym linking.
sudo ln -s domain1.com ../sites-enabled/domain1.com
sudo ln -s domain2.com ../sites-enabled/domain2.com
And your websites should be working correctly .
sudo /etc/init.d/apache2 restart
I understand the tutorial isn't 100% perfect, and may not thoroughly explain certain areas, however I feel the above is enough for you to understand and get multiple virtual hosts on one single server. If you have any questions or suggestions i'll be happy to answer/elaborate on them.
I hope this helps!
