I had a new VirtualHost configuration file that was not showing when using the apachectl -S command   After much head scratching I realised that my file did not have suffix   conf   Once I renamed the file with that suffix my Vhost started showing and working

Here s a command I think could be of some help    apachectl -t -D DUMP VHOSTS   You ll get a list of all the vhosts  you ll know which one is the default one and you ll make sure that your syntax is correct  same as apachectl configtest suggested by yojimbo87    You ll also know where each vhost is declared  It can be handy if your config files are a mess

First check out config files for syntax errors with apachectl configtest and then look into apache error logs

If you are trying to debug your virtual host configuration  you may find the Apache -S command line switch useful  That is  type the following command   httpd -S   This command will dump out a description of how Apache parsed the configuration file  Careful examination of the IP addresses and server names may help uncover configuration mistakes   See the docs for the httpd program for other command line options

I found my own mistake  I did not add log file name       ErrorLog  var log apache2  And this path        Directory   usr share doc   Did not contain website sources    After I changed these two  all worked   Interestingly  apache did not issue any errors  just did not open my website silently on my Mac OS Sierra

I recently had some issues with a VirtualHost  I used a2ensite to enable a host but before running a restart  which would kill the server on fail  I ran  apache2ctl -S   Which gives you some info about what s going on with your virtual hosts  It s not perfect  but it helps
