问题
I removed MAMP recently.
When I try to start apache from Terminal using:
sudo apachectl -k restart
I am getting the message
Warning: DocumentRoot [usr/docs/dummy-host.example.com] does not exist.

First, make sure you're actually trying to execute the proper version of apachectl by issuing the following command:
which apachectl
(You don't want to see any MAMP references there).
Next, find your virtual hosts config (which is likely here if your MAMP references are gone)
/etc/apache2/extra/httpd-vhosts.conf
Make sure your virtual host definitions are good. (Sounds like you're referencing a bad one).
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot "/Users/yourusername/Sites/mysite"
ServerName mysite.local
ErrorLog "/private/var/log/apache2/mysite-error_log"
CustomLog "/private/var/log/apache2/mysite-access_log" common
</VirtualHost>
(If you're using a custom server name other than 'localhost' like I've defined above, just be sure your /etc/hosts file is up to date with that entry like this:
127.0.0.1 mysite.local
Don't forget to restart apache!
sudo apachectl restart

You probably need to go to apache config file (something like etc/apache2/apache2.conf) and set it an existing document root directory. That is usually done with DocumentRoot directive in this file, or one of the included virtual host config definitions.

Make sure you comment out all the lines inside the /etc/apache2/extra/httpd-vhosts.conf file otherwise you will get the errors.
