phpmyadmin “Not Found” after install on Apache, Ubuntu

After installing phpmyadmin, it seems I should be able to access it at http://localhost/phpmyadmin but apache returns a Not Found error. Did this guide leave out a configuration step somewhere? I have already tried restarting the apache service. 

Run the following command in terminal:

sudo ln -s /usr/share/phpmyadmin /var/www/html/

when I try to connect using TNS within Excel I get the error:
Message=ORA-12154
"could not resolve the connect identifier"

how to solve it??

To clarify Hambone's response, to connect Excel to Oracle via Oracle client driver without using TNS Names:

    1.Go to Control Panel > Administrative Tools > ODBC Data Sources
    2.Go to File DSN tab
    3.Choose Oracle driver (e.g. Oracle11gr1)
    4.Provide a name for the new data source (any name)
    5.When prompted for Service Name, enter host:port/servicename e.g. db123:1521/service123
