    I do not know how useful it is, but just to establish:

    $ sudo apt-get install -y php5-tidy
    $ sudo a2enmod expires
    $ sudo a2enmod headers
    $ sudo service apache2 restart

To enable mod_expires and mod_headers just run:

sudo a2enmod expires headers
sudo service apache2 restart

To enable HTML Tidy, run:

sudo apt-get install php5-tidy

    thanks man.
    but on both operation i get this msg.. 

    root@mrcmanager:~# sudo service apache2 restart
 * Restarting web server apache2
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
                                                                         [ OK ]

    is there anything i need to worry about?

    also how to activate these options?? i believe these are also important

    cURL extension: Not installed (required for Amazon S3, Amazon CloudFront, Rackspace CloudFiles support)
Opcode cache: Not installed
HTML Tidy extension: Not installed (required for HTML Tidy minifier suppport)

    The first thing is just an information message. It's safe to ignore it. Apache is restarting successfully.

    For the cURL extension, install it with sudo apt-get install php5-curl

    Opcode cache: Not installed seems to be a bug in W3 Total Cache's detection script. It is enabled and running by default on Ubuntu 14.04. You can verify this by running php -v

    You should see something like:

    PHP 5.5.9-1ubuntu4.5 (cli) (built: Oct 29 2014 11:59:10)
