Ubuntu – Apache2 list all DNS available and certificate files used by them

Display a list of all available DNS:

/usr/sbin/apache2ctl -S 2>&1 | awk '/namevhost/  {print $4;} '

Or you could use the following command

# apache2ctl -S

And with some awk magic have it in the desired format:

# apachectl -S 2>&1 | perl -ne 'm@.*port\s+([0-9]+)\s+\w+\s+(\S+)\s+\((.+):.*@ && do { print "$2:$1\n\t$3\n"; $root = qx{grep DocumentRoot $3}; $root =~ s/^\s+//; print "\t$root\n" };'

Lista the file path for all vhost certificates:

grep -n “Certificate” /etc/apache2/sites-available/* | grep ‘crt|key’

or you you want only uncommented lines:

grep -vnr '#' /etc/apache2/sites-available/* | grep 'crt\|key\|ServerName'
