====== Facebook Accelerators Knowledge Base ======

<note warning>**Warning:** This knowledge base applies to **Facebook Accelerators** only (those with **%%.fb.joyent.us%%** in their hostnames). </note>

If you are hosted on a standard Joyent Accelerator (e.g., if you have an Accelerator ID of '**z12345AA**'), many of the features described here will be missing or will look different. You should refer to the [[accelerators:kb:start|Joyent Accelerators Knowledge Base]] instead. 

Similarly, this knowledge base does not apply to Joyent Shared Accelerators (one of [[shared:directory|these hosts]] you want to refer to the [[shared:kb:start|Shared Accelerator Knowledge Base]].

===== Managing your Accelerator =====

You have root access so you are able to install almost anything (providing you do not violate the [[http://joyent.com/about/legal/accelerator-acceptable-use-policy|AUP]]).  

The baseline deployment options on these accelerators are:

  * Apache with PHP via mod_php or FastCGI
  * Apache with Python via mod_python or via FastCGI
  * Apache in front of Mongrel for Ruby / Rails

==== Software Installed ====

  - [[swphp]]
  - [[swpython]]
  - [[swgems]]
  - [[memcache]]

  - [[rsync]]
  - [[scponly]] (used for restricted SFTP-only users)


==== Domains ====
<note important>Your xxxxxxxx.fb.joyent.us is already mapped to your IP.  If you wish to have any other Domain names served from the accelerator, you will need to use a third party Name service </note>
  - [[domains]]
  - [[domain-alias]]
  - [[default-site]]


===== Mail =====

You can send email from your Accelerator using sendmail (/opt/local/bin/sendmail) or by connecting to the SMTP server on 127.0.0.1:25. You are restricted to sending email to 500 recipients per hour.  You are not able to receive any email with the out-of-box configuration, though all of the parts are there (postfix, courier) for you to configure on your own if you so desire.  

<note tip> Upgraded facebook Accelerators do not have the sending restrictions.</note>

===== Databases =====
<note tip>We recommend that you create another database login to use for your application.  In your welcome email the password for MySQL root is listed.</note>
The two databases which are preinstalled on your Facebook Accelerator are MySQL and PostgreSQL.  You have root access to the machine if you prefer another database, install it.



==== Managing databases ====
=== MySQL ===
MySQL is up and running on your delivered Facebook Accelerator.  Your welcome email contains the root password for your database.
