Sometimes I need to install directadmin on our vds servers, as we don’t use templates for this I was looking for an easy and faster way to install new servers.
A couple of weeks ago I found the solution and i thought I’d share it.

apt-get install gcc g++ debianutils binutils make autoconf automake vim pwgen
wget http://www.directadmin.com/setup.sh
chmod +x setup.sh
mkdir -p /usr/local/directadmin/custombuild
wget http://bugoff.be/wp-content/uploads/2010/04/options.conf -O /usr/local/directadmin/custombuild/options.conf
echo 1.2 > /root/.custombuild
./setup.sh <User ID> <License id> <servername> <eth>

This will install your directadmin server with my options.conf file, correct the options to what you want. I always install my servers using php-cgi.
