Automating virtual host creation

After having created the template, we can now use this to create virtual host configurations. In the simplest terms, we need to replace the dummy-host.example.com URL with the sales.example.com or marketing.example.com URL. Of course, we have to also create the DocumentRoot directory, the directory where the web pages will be, and also add some basic content. When we use a script to run through the process, nothing will be forgotten and the edits will be accurate every time. The basics of the script will be as follows:

#!/bin/bash 
WEBDIR=/www/docs 
CONFDIR=/etc/httpd/conf.d 
TEMPLATE=$HOME/template.txt 
[ -d $CONFDIR ] || mkdir -p $CONFDIR 
sed s/dummy-host.example.com/$1/ $TEMPLATE > $CONFDIR/$1.conf 
mkdir -p $WEBDIR/$1 
echo "New site for $1" > $WEBDIR/$1/index.html 

We can ignore the shebang in the first line; we should know...
