Current Stable Release

Latest stable builds of ccHost are available in several common archiving formats (.zip, .gzip, etc.)

ccHost download page

To install: Unpack the contents of the archive on your local machine and see the README.

Experimental Thrice-Daily Builds

Currently, ccHost packages are being made three-times a day and are available here:

ccHost 3x daily builds

Our experience has been very good however these are minimally tested builds so download, install and use these packages at your own risk.

Only 30 days worth of builds are saved currently.

Install

As stated above, all the information you need for installation is in the distribution package you downloaded. Treat these notes as addendums, hints and other possibly useful information.

Simple

The easiest way to get going is to start with a web hosting server. Common web hosting services like Dreamhost and WebsiteSource provide an administration interface for setting up a mysql database. Hosting services also provide some FTP or SFTP mechanism to upload the ccHost installation files as well. 99% of all services provide support for PHP as well. If you have questions about support in this area, check the server requirements below and with your hosting service.

1. Unzip the ccHost ZIP archive on your local system and copy the files to your server retaining the the directory structure.
2. Browse to http://where_you_installed/ccadmin and follow all the instructions from then on.

Advanced

If you have basic knowledge of using FTP and you are comfortable at a terminal command line you can use these steps to before, during and after installation. Many of these can be filed under "you'll be glad you did" by the time you get to the browser-based installation steps later on.

Enabling 'Pretty URLs'

All ccHost commands and URLs based on query strings:

http://your_install_root/index.php?ccm=/media/people/victor

That same URL can be made 'pretty' on Apache installations so that it looks more like:

http://your_install_root/media/people/victor

Here is the block of code in your .htaccess file setting the rewrite rules to get pretty urls:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /index.php?ccm=/$1 [L,QSA]

If you installed to a directory below the site's root make sure to specify that in the RewriteBase directive.

For perfomance reasons (and if you are given access) you should put those directives into an Apache virtual host block in the .conf file for your server:

<VirtualHost *:80>
ServerName ccmixter.localhost
ServerPath /ccmixter
#DocumentRoot /var/www/localhost/htdocs/cchost 
DocumentRoot /home/rejon/Documents/freelance/creativecommons/src/ccmixter

<Directory "/home/rejon/Documents/freelance/creativecommons/src/ccmixter">
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /index.php?ccm=/$1 [L,QSA]
</Directory>
</VirtualHost>

getID3

ccHost depends on the getID3 library for verifying uploads. Install getID3 (at least 1.7.3) here: http://www.getid3.org/#download before you install ccHost. (It's a simple download-unpack operation.)

For example (on Linux):

tar xzf getid3.tar.gz
cp -a getid3/getid3 /var/www/localhost/htdocs/getid3/

The ccHost installer will 'find' your getID3 installation if it's roughly in the same area of the server, however it is not required that your getID3 be visible on the web and in fact, it's probably more secure if it isn't.

ccHost Terminal Installtion

• Unzip the ccHost ZIP or tar. bz2 archive on your local system and copy the files (retaining the directory structure) to your web-server directory.
• On Linux change the group and permissions of the files so they may be written by the web server (e.g., in the following lines, the web-server account is "apache").

For example:

cp -a cchost-1.0.3 /var/www/localhost/htdocs/cchost
chgrp -R apache /var/www/localhost/htdocs/cchost
chmod g+w /var/www/localhost/htdocs/cchost/
chmod -R g+w /var/www/localhost/htdocs/cchost/cclib/phptal/phptal_cache/

• Create a new database for ccHost (e.g., named "cchost") and create an administrative user to access it (e.g., "cchostadmin"). For example:

mysql -p -u root
mysql> CREATE DATABASE cchost;
mysql> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE ON cchost.* TO 'cchostadmin'@'localhost' IDENTIFIED BY 'YOUR_PASSWORD_HERE';

Make sure to change 'YOUR_PASSWORD_HERE' (and maybe 'cchostadmin') to something unique to your site. (Many systems provide phpMyAdmin to take care of these tasks.

• Create directory /var/log/cchost or other location to store log files. Must be writable by the web-server account (e.g., "apache"). For example:

mkdir /var/log/cchost
chown apache:apache /var/log/cchost

Finish with Install

Browse to http://where_you_installed_cchost/ccadmin

Everything else you need to know will be on the screen from that point on, including suggested php.ini and .htaccess settings, access permissions requirements, etc.

More .htaccess file settings

Put the following into a file named '.htaccess' in your root directory of a ccHost setup if you can't set your php.ini settings for your hosting setup. These settings should work, but should be tested first. They correct many memory problems people have with ccHost.

# php configs http://www.php.net/manual/en/ini.core.php#ini.memory-limit

Upgrading

Always make a backup of your mySQL ccHost database and the files you changes (probably all of the ccfiles directory) before you start the upgrade process. Things go wrong. You have been warned.

General

In general, small updates and patches come in a few files and only require that you copy over cclib and ccextras. Once you've copied the new system files

1. Log in as administrator to your current install (make sure to check 'Remember Me')
2. Browse to: http://where_you_installed/?update=1

Upgrading from 2.x to 3.0

This specific upgrade requires a few extra steps

1. Make a BACKUP of your mySQL database (can be done via phpMyAdmin or from the command line using mysqldump)
2. Make a BACKUP of your cchost directory onto your local machine (skip the /people and /contests directories). If you skip this step and you made changes (to say ccfiles/home.xml) then ALL YOUR CHANGES WILL BE LOST FOREVER
3. Login to ccHost as your admin account and make sure to check 'Remember me'
4. Unzip the cchost 3.0 package on your local machine
5. Copy everything under the cchost directory EXCEPT ccadmin over your server's ccHost directory
6. Delete the file ccextras/cc-language.php
7. Delete ALL files under cclib/phptal/phptal_cache
8. If you made changes to files in ccfiles (like home.xml), copy your local version over the ones on your server now.
9. Browse to: http://where_you_installed/?update=1

Zeitgeist

Goal

The goal of this project is to spread media content that is licensed under Creative Commons throughout the web in much the same way that weblogs spread CC licensed text.

Short Description

"Web-based System Supporting Remixing and Collaboration on Media"

Slightly Longer Description

ccHost is an open source (GPL licensed) project that provides web-based infrastructure to support collaboration, sharing, and storage of multi-media using the Creative Commons licenses and metadata. It is the codebase used by ccMixter and other sites.

Besides its focus on sharing content, ccHost differniates itself from other multi-media hosting programs by emphasizing the reuse (a.k.a. remixing) of content between artists, not only between artists on any given installation of ccHost, but between all installations across the web and any web site that implements the Creative Commons Sample Pool API, including non-ccHost sites such as the freesound project.

Appendix A: Compatibility

Browsers

Tested on: Firefox 1.0+ Mac/PC/Linux, IE 6+ PC, Safari Mac

Cookies must be enabled.

Most skins (the ones people will want to use) require Javascript enabled.

Servers

Primary development is done on Windows XP and up-to-date Linux development systems using Apache, mySQL, and PHP.

Linux

ccHost on Apache (2.0.49 up to at least apache-2.0.55-r1) on Linux,

One should be able to easily install mySQL, PHP, and Apache (if they are not already available) through their distributions packaging system.

Windows IIS Server

Windows users with their installation disks may install optionally the Windows IIS Web Server. This option has been tested. However, there might still be issues with it, and if so, please file a bug.

Even if you using Apache on Windows you may need to have IIS installed if you plan to use mail contact functions.

XAMPP

Windows installations without Apache, mySQL and PHP already installed may want to considering using XAMPP for Windows, which provides an easy install of Apache web server, MySQL database server, and PHP and perl programming languages. This is an easy way to get up and running, with the underlying technology necessary to use ccHost.

Follow the instructions for installation of XAMPP to know where to put the uncompressed ccHost package to properly work with your local setup.

Mac OS X

NOTE: This setup is similar to Linux.

Verified:

• OS X 10.4.6
• default OS X MySQL build, 4.0.26
• GetID3 1.7.7
• default Apache/PHP

Appendix B: Redistribution

HOWTO Tag a Release

Really, each major release needs to be tagged, but this 2.0.1 is the first SVN release, and we did it post CVS -> SVN migration. In the future, this is the proper way to tag and branch.

svn copy https://svn.sourceforge.net/svnroot/cctools/cchost/trunk \
https://svn.sourceforge.net/svnroot/cctools/cchost/tags/2_0_1 \
-m "Tagging 2.0.1 bugfix release"

Here is more about SVN merging/branching.

Packaging

Sign Package

You should do this for all packages (RPM, tar.gz, zip, tar.bz2, etc)

gpg --detach-sign --armor cchost-VERSION.tar.gz

Verify Package

gpg --verify cchost-VERSION.tar.gz.asc
