Site Configuration

Store site content in /home/www

mkdir /home/www
chown www-data:www-data -R /home/www

Path goes with TLD first, and a few other rules. Access and Error logs are stored in the TLD's directory, with the subdomain prefixed. E.g:

Domain / Subdomain		Root Dir
www.attie.co.uk	→	/home/www/attie.co.uk/htdocs
wiki.attie.co.uk	→	/home/www/attie.co.uk/wiki
joke.test.attie.co.uk	→	/home/www/attie.co.uk/test.joke

As the default configuration will deny access to .ht*, we can use .htinfo to store the configuration and logs.

Content	${ROOTDIR}/
Config	${ROOTDIR}/.htinfo/config
Access Log	${ROOTDIR}/.htinfo/access.log
Error Log	${ROOTDIR}/.htinfo/error.log

Start/Restart

service apache2 restart

Setup sites

Add a site file in /etc/apache2/sites-available. Enable the site by symlinking it into /etc/apache2/sites-enabled.

If there is a reason to load one site before another, then use a prefix other than 50.

ln -s /home/www/attie.co.uk/htdocs/.htinfo/config /etc/apache2/sites-enabled/50-www.attie.co.uk

Sample config

<VirtualHost *:80>
  ServerAdmin webmaster@attie.co.uk
  ServerName attie.co.uk
  ServerAlias www.attie.co.uk
  DocumentRoot "/home/www/attie.co.uk/htdocs"
  CustomLog "/home/www/attie.co.uk/htdocs/.htinfo/access.log" combined
  ErrorLog "/home/www/attie.co.uk/htdocs/.htinfo/error.log"
</VirtualHost>
