Apache не работает - ошибка «отказано в подключении»

Я использую Mac Yosemite. Apache 2.4.16. Мой localhost и локальные сайты перестали работать. Они работали нормально уже несколько месяцев, пока я не попытался обновить / исправить MySQL. Я получаю следующую ошибку:

This site can’t be reached
localhost refused to connect.
ERR_CONNECTION_REFUSED

Результаты для ps aux | grep "httpd":
3182 0.0 0.0 2432772 652 s002 S+ 8:46AM 0:00.00 grep httpd

Числа в строке выше меняются каждый раз, когда я запускаю ps aux | grep "httpd". Не уверен, ожидается ли это.

Когда я запускаю killall -9 httpd:
No matching processes belonging to you were found

Мой хост-файл:

##

# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.

httpd-vhost.conf:

# Virtual Hosts
#
# Required modules: mod_log_config

# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs/2.4/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#


<VirtualHost *:80>
  DocumentRoot "/Users/<myusername>/projects/test"
  ServerName test.local
  <Directory "/Users/<myusername>/projects/test">
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    Require all granted
  </Directory>
</VirtualHost>

Я изменил свое настоящее имя пользователя на только для этого сообщения.

apachectl configtest возвращает:
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using <myusername>-iMac.local. Set the 'ServerName' directive globally to suppress this message Syntax OK
