httpd.conf中更改后本地主机无法正常工作 - apache

OSX Yosemite 10.10
2.4 apache

Error: After localhost in browser, I get below error:

The requested URL / was not found on this server.

Following are the changes I've made:

1 file httpd.conf

changed username to mine, it belongs to groups _www So group is unchanaged.

uncommented

LoadModule php5_module libexec/apache2/libphp5.so

In
etc/apache2/extra/httpd-userdir.conf
Include /private/etc/apache2/users/*.conf

#LoadModule userdir_module libexec/apache2/mod_userdir.so

#Include /private/etc/apache2/extra/httpd-userdir.conf

--

ServerName localhost

File /etc/apache/users/myname.conf has Directory pointing to:

/Users/myname/Sites

With

Options Indexes MultiViews FollowSymlinks
AllowOverride All
Order allow,deny
Allow from all

Points:
- I've not edited Directory or DocumentRoot in httpd.conf - I have info.php in /users/myname/Sites folder - Am I running it incorrectly? Tried in browser as:

localhost, localhost/myname/Sites/info.php, localhost/info.php

Nothing worked.

apachectl configtest
AH00112: Warning: DocumentRoot [/usr/docs/dummy-host.example.com] does not exist
AH00112: Warning: DocumentRoot [/usr/docs/dummy-host2.example.com] does not exist
Syntax OK

Restarted server every time I made changes.

chmod 777 ~/Users/myAccount/Sites

Please guide me here.

PS: I am fresh to apache, webserver, config file settings.
