Installation Workflow
--------------------------------------

.. note :: In the following lines you will find ``as administrator user`` note,
           on Ubuntu you have to add ``sudo`` at the beginning of line, on Debian
           you can use ``su -c COMMAND``)

::

  svn checkout http://svn.zoo-project.org/svn/trunk zoo-project

- install cgic from packages

::

  cd zoo-project/thirds/cgic206/

- compile

::

  make

- if you want use Mapserver (optional) for WMS, WFS and WCS output read :ref:`mapserver`

- go to kernel path

::

  cd ../../zoo-project/zoo-kernel/

- create configure file

::

  autoconf

- run configure

::

  ./configure --with-js --with-python

.. note:: For PHP, you must make sure to compile PHP with `--enable-embed <http://www.zoo-project.org/trac/wiki/ZooKernel/Embed/PHP#ConfigureandInstallPHPEmbedlibrary>`__.

.. note:: To use MapServer add the option ``--with-mapserver=/path/to/mapserver/source`` 

- compile

::

  make

- copy necessary files into your cgi-bin (as administrator user)


::

  cp main.cfg /usr/lib/cgi-bin
  cp zoo_loader.cgi /usr/lib/cgi-bin

- install ZOO ServiceProvider, in this case we try Python service (as administrator user)

::

  cp ../zoo-services/hello-py/cgi-env/*.zcfg /usr/lib/cgi-bin
  cp ../zoo-services/hello-py/*.py /usr/lib/cgi-bin/

- change some information in the main.cfg (as administrator user)

::

  nano /usr/lib/cgi-bin/main.cfg
  - serverAddress = http://127.0.0.1


- try the installation

  - http://127.0.0.1/cgi-bin/zoo_loader.cgi?ServiceProvider=&metapath=&Service=WPS&Request=GetCapabilities&Version=1.0.0
  - http://127.0.0.1/cgi-bin/zoo_loader.cgi?ServiceProvider=&metapath=&Service=WPS&Request=DescribeProcess&Version=1.0.0&Identifier=HelloPy
  - http://127.0.0.1/cgi-bin/zoo_loader.cgi?ServiceProvider=&metapath=&Service=WPS&Request=Execute&Version=1.0.0&Identifier=HelloPy&DataInputs=a=myname

.. note::
   If you have some problem in the execute request using Python service, add the following to ``main.cfg``: 

   ::
   
     [env]
     PYTHONPATH=<YOUR_PYTHONPATH>


Rewrite rule configuration
-----------------------------

- for better readability and fully functional ZOO Kernel, you have to modify the default
  Apache configuration in order to be able to use the http://localhost/zoo/ url directly.
  Run (as administrator user)

::

    nano /usr/lib/cgi-bin/main.cfg
    - serverAddress = http://localhost/zoo

- first, please create a ``zoo`` directory in ``/var/www/`` which is used by Apache as the
  DocumentRoot (as administrator user)

::

  mkdir /var/www/zoo

- Then, please edit the ``/etc/apache2/sites-available/default`` configuration file and add the following
  lines after the Directory block related to /var/www directory (as administrator user)

::

  <Directory /var/www/zoo/>
      Options Indexes FollowSymLinks MultiViews
      AllowOverride All
      Order allow,deny
      allow from all
  </Directory>

- now create a small .htaccess file in the ``/var/www/zoo`` containing the following lines (as administrator user)

::

  RewriteEngine on
  RewriteRule call/(.*)/(.*) /cgi-bin/zoo_loader.cgi?request=Execute&service=WPS&version=1.0.0&Identifier=$1&DataInputs=sid=$2&RawDataOutput=Result [L,QSA]
  RewriteRule (.*)/(.*) /cgi-bin/zoo_loader.cgi?metapath=$1 [L,QSA]
  RewriteRule (.*) /cgi-bin/zoo_loader.cgi [L,QSA]


- for this last file to be taken into account by Apache, you must activate the
  rewrite Apache module by copying a load file as bellow (as administrator user)

::

  cp /etc/apache2/mods-available/rewrite.load /etc/apache2/mods-enabled/

- or using the a2enmod tool this way (as administrator user)

::

  a2enmod rewrite

- now you should be able to access the ZOO Kernel using a simplified by restarting
  your Apache Web server (as administrator user)

::
  /etc/init.d/apache2 restart

- now you can try:

  - http://localhost/zoo/?Service=WPS&Request=GetCapabilities&Version=1.0.0
  - http://localhost/zoo/?Service=WPS&Request=DescribeProcess&Version=1.0.0&Identifier=HelloPy
  - http://localhost/zoo/?Service=WPS&Request=Execute&Version=1.0.0&Identifier=HelloPy&DataInputs=a=myname

.. _mapserver:

Compile MapServer
------------------

- install MapServer dependencies (as administrator user)

::

  apt-get install git libfreetype6-dev libproj-dev libkml-dev libcairo-dev libxml2-dev libgd2-xpm-dev libxslt1-dev

- extract MapServer from git repository

::

  git clone https://github.com/mapserver/mapserver.git
  cd mapserver
  git checkout branch-6-2
  git pull

- now compile MapServer

::

  ./configure --with-ogr --with-gdal --with-wfsclient --with-wmsclient --with-tiff --with-jpeg --with-gd --with-wcs --with-sos --with-xml2-config --with-wfs --with-fastcgi --with-proj --with-cairo --with-kml=yes --with-xslt --with-threads --with-geos
  make

- now install MapServer (as administrator user)

::

  make install

- now add path to libraries path (as administrator user)

::

  nano /etc/ld.so.conf.d/mapserver.conf
  - /usr/local/lib/

- run as administrator

::

  ldconfig
