Urchin Installation for Unix
(version 2.1 and higher)

 

Urchin Dedicated is a fast web server log file analysis program for one or more sites running on one web server. It produces usage reports in HTML format for viewing with a standard web browser. Urchin Dedicated is meant to be installed directly on the web server. Because its process overhead is minimal, this does not represent a significant performance issue. In the most basic terms, Urchin Dedicated reads the server's log file(s), put the information in the VIDA(tm) database, and then deliver HTML-based reports as requested. The log-processing engine is called from 'cron' (UNIX) or the Windows scheduler.

IMPORTANT NOTES:
- Urchin3 and Urchin4 are independent and non-interchangeable resources. Make sure you don't confuse them.
- Urchin Lisence Manager is to be used only for Urchin3. New Urchin4 is managed without it.
- H-Sphere has no migration tool to move statistics between Urchin3 and Urchin4. For migration use standard utilities provided by Urchin.


1) Download Urchin archive from:
http://www.urchin.com/download/ or ftp://ftp.urchin.com/pub/ to the /hsphere/local/ directory.
* You should have root permissions to do it.

2) Unpack the downloaded archive. The archive will automatically create the urchin directory. You'll get something similar to the following:
/hsphere/local/urchin3400d_redhat7x.tar.gz

Then execute the following:
cd/hsphere/local/
gunzip urchin3400d_redhat7x.tar.gz
tar -xvf urchin3400d_redhat7x.tar

Finally you'll get:
/hsphere/local/urchin3400d/*.*

3) Rename new directory urchin3400d to urchin

4) Edit the Urchin config file:

Go to /hsphere/local/urchin/config file:
Open it and set the following variables to these values:

LogDestiny [leave the default value for this variable, do not change anything]
RestartCommand: /hsphere/shared/scripts/apache-reconfig
Symlinks: linknone

5) Enter your control panel as admin and go to Plans->Resources->UnixResources->RLimitMEM->Edit. Experiment with the Max value to see which is best for Urchin or set it to unlimited.

Now you can go to Adding Urchin Licenses.
