Introduction to Web Stack Review of Current Web Stack Components Demos Summary


3/27


Looking Back to Summer '07 Web Stack project started in July 2007

OpenSolaris had> Apache httpd - outdated version

>MySQL - outdated version> No PHP or other web tier components available from Sun

A heavyweight integration process> I estimated about 2.5 new components per year per full-time engineer

> Making it nearly impossible for OpenSolaris to catch up to otherdistributions in application availability

> A source repository model which cannot scale to present needs sfw consolidation = all general-purpose open source components in a

single source tree built together at the same time


4/27


Web Stack Project

One sentence summary:> The goal of this project is to address the OpenSolaris community needs

for web tier technologies

A project within OpenSolaris

> Pure open source effort, all build trees on opensolaris.org> http://opensolaris.org/os/project/webstack/

Contributors from a wide range of groups within Sun

Package contribution from all of you are welcome!> Sadly external contributions still have excessive overhead> But it is improving and alternatives are emerging!

> Join the list to influence design decisions based on your needs

> Contact Jyri Virkki for guidance if you are interested in owning thedelivery of any new web tier component

Web Stack Project Goals

As first priority, deliver (or update) the AMP components inOpenSolaris> Components are being integrated into the public source tree available

from OpenSolaris.org> Therefore became available in both SXDE/SXCE distributions as well asOpenSolaris distributions

Project started by targeting the inclusion of a fully integratedAMP stack into SXDE 1/08 (done!)

With more components and additional functionalitybecoming available in May'08 OpenSolaris distribution

7/27Sun Confidential: Internal Only 7


Highlights of OpenSolaris integration areas:> smf support- daemon processes (such as Apache, Squid, MySQL) are

enhanced to be manageable via smf

> dtrace probes - dtrace is a key observability advantage in OpenSolaris,therefore Web Stack project seeks to enhance components with dtrace

probes wherever applicable> zones/layout compatibility- components are configured to be compatible

with OpenSolaris layout needs e.g. configuration under /etc, runtime variable files under /var

and so on

> RBAC support- where applicable, components define rights profiles soadministration can be delegated

OpenSolaris performance> We seek to fix bugs and tune configuration for optimal performance on

OpenSolaris (and on scalable hardware)



Dtrace: OpenSolaris killer feature

Comprehensive tracing facility used to examine the behaviorof both user programs and of the OS.

Understand how the system works, track down performance

problems across many layers of software, or locate thecause of aberrant behavior.

Dynamically modify the OS kernel and user processes torecord additional data that you specify at locations of

interest, called probes. Probes are like programmable sensors scattered all over

your OpenSolaris system in interesting places




Another key goal of the project is to help improve thedelivery time and process> Delivering components necessary but not sufficient

> We need to enable distributed, streamlined delivery in order to trulysucceed in the long term

We have been able to drive improvement in the agility of theprocess of making open source components available forOpenSolaris

We are also working hard on making the process moretransparent and more accessible> So that all of you can contribute your favorite components through a

convenient process



Where We Are Today

Full AMP stack (and more) available and integrated> More detail in next section

Integration processes are improving so we can acceleratedelivery> But most improvements are not very visible outside Sun yet so work

remains

Web Stack delivery goals are aligning closely with the riseof IPS package distribution

> Experimental repository already available

Source repository model not quite resolved yet (thoughalternatives appearing)> (Components still going into a single consolidation, will not scale)



A Word on CoolStack

CoolStack is a related project> Also hosted by the Web Stack community

> Also delivers web tier components

> http://opensolaris.org/os/project/webstack/coolstack/> http://cooltools.sunsource.net/coolstack/

Target is currently Solaris 10> For current production systems

> Support pilot program in place> Delivered as unbundled applications (under /opt)

> Not fully integrated into Solaris (no smf/RBAC/etc integration)

> Performance tuned for Solaris



Looking Ahead

More components> lighttpd, applications/frameworks (drupal), administration components and

much more

> As always, suggest/contribute: [email protected]

More features> PHP pear/pecl, 64bit, more modules and extensions

> Performance improvement work across the board

Continue to drive unconsolidation

> Fulfill the need for a scalable (tens of thousands of packages) andmaintainable source and build infrastructure

Most importantly:> Simplify ways for you to participate and contribute



Beyond Web Stack

While this talk concentrates on web tier components> and how to improve content and timeliness of delivery in our area

That's just a start...

Ultimately these delivery improvements are needed in allareas for OpenSolaris, not only Web Stack

Food for thought...> Debian stable currently has O(20000) packages

Let's get there for OpenSolaris First we must make it easy for you to participate...

It's happening!



Agenda

Introduction to Web Stack Review of Current Web Stack Components

Demos Summary


15/27


Apache HTTPD

Current version is 2.2.8> Both worker and prefork MPMs

> Both 32bit and 64bit

> SUNWapch22 and SUNWapch22d (documentation)

mod_dtrace, mod_fcgid, mod_security, mod_jk, mod_php> In addition to a long list of included modules

> SUNWapch22m-* packages

Look for it in

> /usr/apache2/2.2/*, /etc/apache2/2.2/*, /var/apache2/2.2/*> Live configuration goes into /etc/apache2/2.2/conf.d/

(sample configs found in /etc/apache2/2.2/samples-conf.f/)

% svcadm enable apache22

Apache 22 Administration::::auths=solaris.smf.manage.http/apache22,solaris.smf.value.http/apache22


16/27


MySQL

Current version is 5.0.45> SUNWmysql5

dtrace support added in latest version> Not yet in the integrated (5.0.45) version

> ... but soon to be included

Look for it in> /usr/mysql/5.0/*, /etc/mysql/5.0/*, /var/mysql/5.0/*

Profile:> MySQLAdministration::::auths=solaris.smf.manage.mysql/version_50,

solaris.smf.value.mysql/version_50


17/27


PHP

Current version is 5.2.4 (soon to be updated)> SUNWphp524[core|doc|usr|man] (package split to be fixed)

> Many extensions are included

Some extensions packages separately for dependencies> SUNWphp524-mysql, SUNWphp524-pgsql

Look for it in> /usr/php5/5.2.4/*, /etc/php5/5.2.4/*

To enable in Apache, simply install the package> It will install a php5.conf into apache conf.d to enable itself> # pkg install SUNWapch22m-php5

> % cat /etc/apache2/2.2/conf.d/php5.conf


18/27


Beyond Just AMP

There is more to Web Stack than AMP components All web tier applications (and related libraries) are in scope

Available today from pkg.opensolaris.org:

Squid (2.6.STABLE17) [SUNWsquid]> smf support included> svcadm enable svc:/network/http:squid

Ruby (1.8.6) and gems (0.9.4) [SUNWruby18]

> Ruby includes dtrace probes as well http://blogs.sun.com/prashant/entry/dtrace_support2

> gem support included for installing additional components e.g. Rails

memcached (1.2.5) [SUNWmemcached]

19/27


Experimental Components

Web Stack also provides experimental components> These components may or many not work on any given day and they are

updated often...

Some are early access builds

> Projects which are on track to become fully integrated> Still in development but available for early access testing

One example today is lighttpd (SUNWlighttpd) - try it out!

And some are just experiments (for now?)

> No immediate plan to promote to the primary repositories> But if there is interest (or volunteer owners), can be promoted

> Examples today include: varnish (SUNWvarnish), phpMyAdmin (SUNWphp5-myadmin)


20/27


Experimental Web Stack Repository

Today, only Web Stack has experimental repository> Only because Web Stack is the pioneer community

> Desire is to have a home for all experimental packages
