Verify the apache webserver is writable and running

Make a file in the DOMS directory:

echo "Hello world" > /var/www/html/DOMS/test.txt

Retrieve http://localhost/DOMS/test.txt

wget -q -O - http://localhost/DOMS/test.txt

It should show "Hello world".

Clean up after you.

rm /var/www/html/DOMS/test.txt
