Mac OS X - Internal WebServer

Mac has his own server, you can start or stop it like this:

sudo apachectl start/stop

 

Its locations :

serve files location : Library/WebServer/
software files location : /usr/libexec/apache2/

 

You can set you own serve location/directory :

1 cd /etc/apache2/users/
2 vim ./{username}.conf

<Directory "/Users/{username}/Sites">
Options Indexes MultiViews
AllowOverride All
Order allow,deny
Allow from all
</Directory>

4 chmod 755 ./{username}.conf

5 sudo mkdir ~/Sites

6 browser

http://localhost/~{username}

Then it works . But do not forget the character '~'

 '~/Sites'  directory will be the user level tomcat server directory , while '/Library/WebServer/Documents' is the directory of system level.
