Optimized Open Source Software Stack (Cool Stack)
for the Sun Solaris Operating System(TM)
Important Information
Cool Stack for Solaris 10 has been replaced by the cross-platform GlassFish Web Stack as of
the initial 1.4 release in December 2008. The optimization work introduced with Cool Stack
has been retained in the GlassFish Web Stack. GlassFish Web Stack, like Cool Stack, is
also free to use and supported on a best effort basis via Sun forums
(Web Servers / Infrastructure - Sun Web Stack) however, unlike Cool Stack a support subscription is available for GlassFish Web Stack
for those customers who deploy it in mission critical environments. For more information,
see the GlassFish Portfolio site for more information.
"The Cool Stack site and download images are retained for the near future to aid those
Solaris 10 customers who have already deployed it. We strongly recommend making plans to
migrate to the GlassFish Web Stack at your earliest convenience, as there will be no future
security or other fixes released for Cool Stack.
The upcoming GlassFish Web Stack 1.5 release will bring important upgrades to many of the
open source packages for current Cool Stack 1.3.1 and GlassFish Web Stack 1.4 users.
Overview
Cool Stack is a collection of some of the most commonly used open
source applications optimized for the Sun Solaris OS
platform. By using these binaries you will enjoy the best levels of
performance from your system, while also reducing your time-to-service.
Cool Stack features
Cool Stack includes several packages in the SVR4 package format,
so you can install just the ones you need. Some of the applications
in Cool Stack already ship with Solaris, but these are either older
versions and/or not built with full optimization. Further, Cool Stack
has been pre-configured to have the most popular applications
(Apache, PHP, MySQL) to work seamlessly out of the box.
Cool Stack contents
The following sections lists all of the packages available. For details
on version numbers, modules/extensions included etc. please read the
documentation available on the download site.
- CSKamp.
This package is comprised of 3 packages: CSKapache2, CSKphp5 and CSKmysql32
for a more flexible installation. The 3 components are pre-configured to work
together.
The MySQL included in this package is a 32-bit version with client-side
support to work with PHP. For the database server, we recommend the
CSKmysql package which is a 64-bit version, allowing the use of larger
caches to deliver improved performance for large databases. However,
on smaller systems you can use the 32-bit MySQL in this (CSKamp) package
for the database server.
- CSKruntime.
This package containes core libraries used by many of the other packages and should be installed first.
- CSKmysql.
This package includes a 64bit version of MySQL and is built with
innodb. See the README file in the mysql install directory for details.
- CSKperl.
This package includes Perl 5. In addition to being better optimized, CSKperl
includes several perl extensions used by popular applications.
- CSKlibsbundle
This package consists of libraries required by various PHP extensions and is made up of 3 packages: CSKtds, CSKncurses, CSKlibs
- CSKmemcached.
This package includes memcached, a distributed object cache system.
- CSKruby.
This package includes ruby, rubygems and rails.
- CSKsquid.
This package includes Squid Web Proxy Cache.
- CSKtomcat.
This package includes two packages CSKtomcat5 and CSKtomcat6. Apache Tomcat is a
pure Java application. It is provided for convenience as it is no different
from the one on tomcat.apache.org.
- CSKlighttpd.
This package includes lighttpd, the increasingly popular, light-weight http server.
- CSKpython.
New! This package includes python and mod_python.
- CSKnginx.
New! This package includes nginx, another light-weight http server.

Cool Stack Installation on Solaris 10
You must be 'root' to install the packages. Download the packages you
are interested in into any directory. For each of the downloaded
packages, run the following bunzip2 and pkgadd
commands:
bunzip2 [package.pkg.bz2]
For example: bunzip2 CSKmysql_1.3.1_sparc.pkg.bz2
pkgadd -d [package.pkg]
For example: pkgadd -d CSKmysql_1.3.1_sparc.pkg
This process will install the package in /opt/coolstack, along
with all dependent libraries.
After installation, please refer to the README file included in each
of the application's directories. The README includes detailed
information on the following:
- how the application was built
- Solaris-specific configuration and tuning notes.
- Pointers to other relevant documentation.
- Instructions for setting up SMF service (if applicable).
Cool Stack Installation on OpenSolaris/Solaris Express Developer Edition (SXDE)
Due to some incompatibility in package processing, the data stream format of the packages do not work on some OpenSolaris and older SXDE releases. The solution is to convert the streams to filesystem format. Here is an example :
# pkgtrans CSKamp_1.3.1_i386.pkg /var/tmp
# pkgadd -d /var/tmp
pkgadd will display all the packages available in /var/tmp and you can
now choose to install whichever packages you want.
Upgrading from Cool Stack 1.2/1.3x
If you already have packages from Cool Stack 1.2 or 1.3x installed, please be aware that these will be over-written with the new version. You should back up whatever files you have changed (e.g. apache2/conf directory, php5/lib/php.ini etc.) A safe way to do this is to first rename the current /opt/coolstack directory and then remove the currently installed Cool Stack packages using pkgrm CSKpkgname. Note that pkgrm will not remove files that you added as for e.g. In apache2/htdocs or elsewhere. You can save these files before installing the new packages, then re-copy your saved files back. This process is illustrated below assuming you had only CSKamp installed :
# Save entire coolstack (temporarily)
bash-3.00# mv /opt/coolstack /opt/coolstack1.2
# Delete old Cool Stack 1.2 package
bash-3.00# pkgrm CSKapache2
# Save any files you added after installation
bash-3.00# cd /opt/coolstack
bash-3.00# mkdir /var/tmp/CS_save; cp -rp . /var/tmp/CS_save
bash-3.00# cd /var/tmp/CS_save
# delete all files in /var/tmp/save you don't care about e.g. apache2/logs/*
# Add new Cool Stack 1.3.1 package from wherever you downloaded it to
bash-3.00# bunzip2 CSKamp_1.3.1_sparc.pkg.bz2; pkgadd -d CSKamp_1.3.1_sparc.pkg
# Copy back the saved files. Be cautious and ensure that you're copying back ONLY required files or otherwise you could mess up your package
bash-3.00# cp -rp /var/tmp/CS_save/selected_files /opt/coolstack
# Copy your original config files back from /opt/coolstack1.2. For example:
bash-3.00# cd /opt/coolstack; cp ../coolstack1.2/apache2/conf/httpd.conf apache2/conf
