How to Install Gorg
Gorg is no longer maintained and its use on gentoo.org websites is
being phased out. Once gorg is no longer used on gentoo.org the
package will be masked and removed.
Gorg is a back-end XSLT processor for an XML-based web site. XML source files
are transformed and served on-the-fly. Output files and their dependencies are
cached. Its main features are:
- Works with apache, lighttpd or webrick (ruby's own web server)
- Uses efficient caching
Generates consistent HTTP headers when several web nodes serve the same
Implements its own compression (aka mod_gzip), i.e. it does not rely on the
web server to compress its output
- Supports client-side caching
- Your XSL can accept and write cookies
Provides its own search engine (site indexing will be substantially updated
in a later version)
Gorg allows you to serve your own local copy of
http://www.gentoo.org. It can use either a cgi or a fastcgi script
with apache or lighttpd, or even use its own stand-alone web server. Its name is
short for Gentoo.org because it was created with Gentoo's site in
mind when it was felt that a replacement for AxKit was required.
Gorg has been tested on x86, amd64, alpha, sparc, ppc, mips & hppa with the
Code Listing 1.1: Test environment
Define your USE flags to allow apache with or without mod_fcgi, or not depending
on how you want to use it. The mysql USE flag is only required for the
integrated search engine.
You might have to keyword some dependencies for your architecture. You can
keyword the required packages or accept a foreign architecture. gorg has been
installed and tested on x86, amd64, alpha, sparc, ppc, mips & hppa.
Code Listing 2.1: Emerging gorg
# emerge -pv gorg
# emerge gorg
You may skip this section if you are not going to use apache at all.
If you want to use fastcgi, which you should anyway, you'll need to add -D
FCGID to the APACHE2_OPTS variable in
Then, integrate the apache configuration directives from the provided sample
file /etc/gorg/vhost.sample into your own vhost configs, e.g.:
/etc/apache2/vhosts.d/10_gorg.conf. Comments in the sample config
file will guide you.
Finally, copy or symlink the (c)cgi scripts from
into your web site (f)cgi directories and check they are executable. You
should copy search.cgi only if you are going to use the integrated
Create a copy of the sample config file /etc/gorg/gorg.conf.sample
named /etc/gorg/gorg.conf and edit it. Comments will help
you define your own parameters. You need to define at least your web document
If you do not want to use the default /etc/gorg/gorg.conf config
file, you'll need to define an environment variable called GORG_CONF that
points to the config file.
If you use caching, and it is recommended that you do so, do make sure that the
cache directory defined in your config file has proper permissions. If you use
apache, the apache user needs full access to that directory.
Getting the missing files
Assuming you'll serve your local copy of CVS, or a copy if, or symlinks to it,
you need to download some files from the dyn directory.
Code Listing 3.1: Get the missing files
$ cd /path/to/your/document/root
/htdocs $ cd dyn
/htdocs $ wget -O news-index.xml http://www.gentoo.org/dyn/news-index.xml?passthru=1
/htdocs $ cd ..
You also need to make the pictures available to your browser. The
images directory is one level above htdocs. Just
define a symlink to it and you're set.
Code Listing 3.2: Make a symlink to the pictures
/htdocs $ ln -si ../images images
/htdocs $ ls -l
drwxr-xr-x 3 neysx users 128 Sep 14 17:45 css
drwxr-xr-x 31 neysx users 744 Oct 26 00:03 doc
drwxr-xr-x 3 neysx users 544 Nov 2 16:53 dtd

lrwxrwxrwx 1 neysx users 10 Oct 21 22:29 images -> ../images/

drwxr-xr-x 3 neysx users 736 Nov 2 16:40 xsl
Your local CVS probably shows a few more entries, but at least those mentioned
above should be available and kept up-to-date. Also remember to keep your
images directory current.
The stand-alone web server
The easiest way to try it out is to run gorg. It should display something
Code Listing 4.1: Run gorg
Starting the Gorg web server on port 8008
Hit Ctrl-C or type "kill 31479" to stop it
Point your browser to http://localhost:8008 and you should see your
Restart apache (/etc/init.d/apache2 restart) and visit
http://localhost assuming you're installing on your own
If you used static fastcgi servers, you should see them with top -u
If it doesn't work, try the stand-alone web server (type gorg). If this
doesn't work either, check your /etc/gorg/gorg.conf config file. If
it does work, please check your apache config files and your logs.
