AWS amazon, I was able to make this guide working in 2020.
anyway, for apache2/php7 you have to change this:
000-default-ssl is now default-ssl
also pay attention to symlink creation. if red, something bad. if its blue, good 4 you.
also, depending on the distribution, to check apache you may apachectl -V
cercatore @ github.com
or httpdctl -V
