Deep inside the ClearOS developer documents, there's a short walkthrough on how to "convert" a CentOS system to a ClearOS system.  In essence, it's a walkthrough that shows what's needed to get a barebones ClearOS web-management tool running on top of a CentOS system.  As stated in the doc, it's not recommended for a real world deployment and intended for tinkerers.

http://www.clearfoundation.com/docs/developer/architecture/core_system/clearos-release

Below is a summary for those who don't have the time/interest to break out a VM and perform a walkthrough:

1) A sandboxed Apache/PHP engine is packaged to avoid interfering with the default OS Apache/PHP engine.  Source RPMS required:

- webconfig-httpd (upstream "httpd', but tweaked to run out of /usr/clearos/sandbox)
- webconfig-php (upstream "php", ditto)

2) A slightly modified CodeIgniter PHP framework is used by the web-management interface.   Source RPM:

- clearos-framework


3) A set of barebones "app" packages are required - these are the PHP API/REST/web front-end RPMs.  We can strip out the "must register" type of workflow for a CentOS variant of course, but those are implementation details.  Source RPMs:

- app-language
- app-network
- app-register
- app-suva-core / suva-client (needed for registering)
- app-clearcenter
- app-registration
- app-marketplace


Not all the features listed on the on the following page would be available in a CentOS variant since some require EPEL or ClearOS-maintained packages (e.g. ClamAV, DansGuardian, Snort):

http://www.clearcenter.com/marketplace/

So something like "OpenVPN" would require the "app-openvpn" RPM in addition to the upstream openvpn package.  Most, if not all, of the packages listed in the above URL listed as "free as in beer" are also "free as in speech".

We have 3 types of packages.

1) Modified upstream and ClearOS-maintained packages

CentOS development veterans will recognize this :-)  It's a CVS repository used by plague build system:
http://buildsys.clearfoundation.com/plague/success.psp .  Source code:

cvs -z3 -d:pserver:anonymous@cvs.clearfoundation.com:/var/clearos/cvs/repositories/clearos co rpms

Here's a list of upstream packages that we modify with reasons why we modify (warning: doc is not 100% up-to-speed):  http://www.clearfoundation.com/docs/developer/packaging/clearos_6.x/start

None of the upstream modifications would be required for a CentOS variant but some apps would not be available without the modifications.


2) Internal code used a helpers for some ClearOS features

We have a dozen-ish packages that we have developed to support some apps.  Those are found on Github:
https://github.com/clearos-packages

For example, the "csplugin-routewatch" watches for route modifications from external packages (OpenVPN, IPsec, PPTP) and notifies the multi-WAN app when something changes.

3) PHP API, REST, and web frontend

The "meat and potatoes" -- these are the PHP API/REST/web RPMs.  These will be migrated to Github in the next week or so (https://github.com/clearos), but can be found on svn.clearfoundation.com/clearos right now (web frontend @ http://code.clearfoundation.com/svn/). 

Cheers,

Peter Baldwin
