Some commands I use on my Linode VPS to make life easier.

server-commands.sh

www=/srv/www
conf=/etc/apache2/sites-enabled
alias ra='/etc/init.d/apache2 restart'
alias ownit='chown -R www-data:www-data .'

function makeconf {
primary=${1}
conffile="${conf}/${primary}.conf"
site_path="/srv/www/${primary}"
mkdir -p ${site_path}

echo "<VirtualHost *:80>" >> "${conffile}"
echo "  Servername ${primary}" >> "${conffile}"
echo "  ServerAlias www.${primary}" >> "${conffile}"
shift
for i; do
cat >> "${conffile}" <<EOL
        ServerAlias ${i}
        ServerAlias www.${i}
EOL
done
echo "  DocumentRoot ${site_path}" >> "${conffile}"
echo "</VirtualHost>" >> "${conffile}"
}

function wordpressitup {
wget http://wordpress.org/latest.tar.gz
tar xfz latest.tar.gz
cd wordpress
cp -R * ..
cd ..
rm -r wordpress
echo "Wordpress installed"
}
