First of all, let’s distinguish between error logs and access logs.
In this guide you can see how:
But, I noticed that there was not info in the apache /var/log/apache2.access log
The trick is to add one line to the virtualhost that you would like to control:
CustomLog /var/log/apache/www.foo.com-access.log combined
This instructions will be useful for you if you have a webserver with Ubuntu 12.04 (I have not tested this solution with other versions) running Apache 2.2.
You have a domain configured as a virtualhost. For example: example1.com
You want to change it to example2.com
These are the steps you have to follow:
1. Modify /etc/hosts
should be changed to
2. Rename the file /etc/apache2/sites-available/example1.com to example2.com
mv /etc/apache2/sites-available/example1.com /etc/apache2/sites-available/example2.com
3. Rename the folder where you have the public content, that is the DocumentRoot Apache configuration.
E.g. in my case, this is /var/www/example1.com
mv /var/www/example1.com /var/www/example2.com
4. Disable the former site and enable the new one:
On one hand, this will remove the symlink in /etc/apache2/sites-enabled that refers to /etc/apache2/sites-available.
And on the other this will create a new symlink for the new site.

5. When you are done, restart Apache
service apache2 restart
