Start Apache
1. Go to System Preferences
2. Select "sharing"
3. Check the box "Web Sharing" -- for starting the apache

2. Edit the Host file

For editing you can use nano or mate text editor for command line

sudo nano /etc/hosts

or

sudo nano /private/etc/hosts

You can see the following codes:

#
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0     localhost

add new host local.mysite.dev at end of line

#
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0     localhost
127.0.0.1       local.mysite.dev

3. Switch in the httpd.conf file

sudo nano /etc/apache2/httpd.conf

find the "# Virtual hosts" string using ctl + w and type "# Virtual hosts" without (")

# Virtual hosts 
#Include /private/etc/apache2/extra/httpd-vhosts.conf

un comment the code to enable the VHost

# Virtual hosts 
Include /private/etc/apache2/extra/httpd-vhosts.conf

4. Add virtual host in apache

sudo nano /private/etc/apache2/extra/httpd-vhosts.conf

add these codes:

#
# Use name-based virtual hosting.
#
NameVirtualHost *:80

#
# 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  block.
#
                                                                                                   
< VirtualHost *:80>
  ServerName localhost
  DocumentRoot "/Library/WebServer/Documents"
< /VirtualHost>

< VirtualHost *:80>
  ServerAdmin local@mysite.dev
  DocumentRoot "/Library/WebServer/Documents/mysite/webroot/"
  ServerName local.mysite.dev
    < directory "/Library/WebServer/Documents/mysite/webroot/">
      Options Indexes FollowSymLinks MultiViews
      AllowOverride All
      Order allow,deny
