  • Install Python Cartographic Library

    2006/12/07 by Nicolas Chauvat

    This is how we setup PCL <http://trac.gispython.org/projects/PCL> under debian. Of course having a package would be better...

    Install dependencies

    apt-get install mapserver-bin python-mapscript mapserver-cgi
gdal-bin python-gdal python-dev libgeos-dev libgdal-dev
libgd2-xpm-dev python-setuptools zope-interface
python-elementtree

    Now link libgdal.a to libgdal1.3.2.a

    Install PCL from sources

    svn co  http://svn.gispython.org/svn/gispy/PCL/trunk

cd PCL/

cd externals/OWSLib
python setup.py install --prefix=my_python_library

cd externals/QuadTree
python setup.py install --prefix=my_python_library

cd PCL-Core
python setup.py install --prefix=my_python_library

cd PCL-GDAL
python setup.py install --prefix=my_python_library

cd PCL-MapServer

    Put in a directory the source code of mapserver corresponding to the package version installed above. Get it from http://mapserver.gis.umn.edu/download or with dpkg-src.

    Edit setup.py to set ms_home to the path of the above mapserver sources.

    python setup.py install --prefix=my_python_library

    my_python_library now contains Python eggs and directories with Python and C libraries.

  • Profiter pleinement des CPUs avec Zope/Zeo/Debian

    2008/05/27 by Arthur Lutz

    Voici vite fait comment on profite du quad-core bi-proc multicoeurs avec zope/zeo/pound ... le tout en commandes debian.

    Inspiré de : http://plone.org/documentation/how-to/simple-zope-clustering-with-squid-and-pound

    http://plone.org/documentation/tutorial/introduction-to-the-zodb/zeo%20diagram.png

    • apt-get -uVf install plone-site pound

    • dzhandle -z 2.10 make-zeoinstance sgel_zeo

    • dzhandle -z 2.10 make-instance sgel2 --zeo-server=localhost:8100 -m all

    • dzhandle -z 2.10 make-instance sgel3 --zeo-server=localhost:8100 -m all

    • dzhandle -z 2.10 make-instance sgel1 --zeo-server=localhost:8100 -m all

    • dzhandle -z 2.10 make-instance sgel4 --zeo-server=localhost:8100 -m all

    • modifiez les ports de chaque instance (par exemple 9673, 9674, 9675, 9676)

    • vim ~/zope/instances/sgel*/etc/zope.conf

    • dzhandle add-product sgel1 CMFPlone

    • dzhandle add-product sgel2 CMFPlone

    • dzhandle add-product sgel3 CMFPlone

    • dzhandle add-product sgel4 CMFPlone

    • dzhandle zeoctl sgel_zeo start

    • dzhandle zopectl sgel1 start

    • dzhandle zopectl sgel2 start

    • dzhandle zopectl sgel3 start

    • dzhandle zopectl sgel4 start

    • vim /etc/pound/pound.cfg pour remplacer

      BackEnd
        Address 127.0.0.1
        Port    8080
End

      par

      Service
        BackEnd
                Address 127.0.0.1
                Port    9673
        End
        BackEnd
                Address 127.0.0.1
                Port    9674
        End
        BackEnd
                Address 127.0.0.1
                Port    9675
        End
        BackEnd
                Address 127.0.0.1
                Port    9676
        End
End

    • /etc/init.d/pound restart

    • tapez sur http://localhost:8080

    • ajoutez un site plone

    pour tester, lancez htop pour voir l'activité et regardez la différence entre :

    • apt-get -uVf install apache2-utils
    • /usr/sbin/ab -n 100 -c 100 localhost:8080/plone

    et

    • /usr/sbin/ab -n 100 -c 100 localhost:9673/plone

    nice!
