     6 PyAMS default installation is based on `Buildout <http://www.buildout.org>`_ utility. It's not mandatory to use a
     6 .. toctree::
     7 virtual environment, but it allows you to have a better control over your Python resources.
     7    :maxdepth: 2
     8

     9 Current PyAMS version is based and validated for Python 3.5; your Python environment must also include a C
     9    zodb
    10 compiler as well as development headers for Python, *libjpeg*, *libpng*, *libfreetype*, *libxml2*, *libxslt* and
    10    appinstall
    11 eventually *libldap*, *libpq*, *libffi*, *libgdal* or *libzmq*. *Cython* compiler can also be useful to optimize
       
    12 several packages.
       
    13 
       
    14 PyAMS default components configuration also pre-suppose that the following external tools are available:
       
    15 
       
    16 - a *Memcached* or *Redis* server, to store sessions and cache (can be changed through Beaker configuration)
       
    17 
       
    18 Optional tools also include:
       
    19 
       
    20 - an *LDAP* server for authentication
       
    21 
       
    22 - an *ElasticSearch* server for full text indexing (see *PyAMS_content_es* package)
       
    23 
       
    24 - a *WebSockets* server using AsyncIO. This is used to manage notifications (see *PyAMS_notify* and *PyAMS_notify_ws*
       
    25   packages). An *out of the box* environment can be built using *pyams_notify* scaffold.
       
    26 
       
    27 
       
    28 PyAMS also needs that you use a ZODB shared server, as several background processes needing a concurrent access to ZODB
       
    29 are started by PyAMS main process. Three ZODB storages are already provided through PyAMS: ZEO, RelStorage or Newt.db.
       
    30 See :ref:`zodb` to know how to initialize database with the help of PyAMS tools.
       
    31

    33 Creating initial buildout
       
    34 -------------------------
       
    35 
       
    36 PyAMS provides a new Pyramid scaffold, called *pyams*, generated via a *cookiecutter* template.
       
    37 
       
    38 A simple option to install PyAMS is to create a buildout environment including *Pyramid* and all *PyAMS* packages:
       
    39 
       
    40 .. code-block:: bash
       
    41 
       
    42     # mkdir /var/local/
       
    43     # pip3 install virtualenv
       
    44     # virtualenv --python=python3.5 env
       
    45     # cd env
       
    46     # . bin/activate
       
    47     (env) # pip3.5 install cookiecutter
       
    48     (env) # cookiecutter hg+http://hg.ztfy.org/pyams/scaffolds/pyams
       
    49

   145   that *libgdal* development files are available; on Debian (and maybe others), you have to specify environment
       
   146   variables (see below).
       
   147 
       
   148 
       
   149 Boolean values accept "true", "yes", "on" or "1" (in any case) as *true* values, and anything else as *false*; setting
       
   150 any option to empty string will keep the default proposed value.
       
   151 
       
   152 You can then check, and eventually update, the proposed Buildout configuration file *buildout.cfg*, to add or remove
       
   153 packages or update settings to your needs. Then finalize Bootstrap initialization:
       
   154 
       
   155 .. code-block:: bash
       
   156 
       
   157     (env) # python3.5 bootstrap.py
       
   158     (env) # ./bin/buildout
       
   159 
       
   160 This last operation can be quite long, as many packages have to downloaded, compiled and installed in the virtual
       
   161 environment. If you encounter any compile error, just install the required dependencies and restart the buildout.
       
   162 
       
   163 Some dependencies can require the definition of custom environment variables before running *buildout*, like:
       
   164 
       
   165 - for *libgdal*, which is required by **PyAMS_gis** package, use:
       
   166 
       
   167 .. code-block:: bash
       
   168 
       
   169     (env) # export C_INCLUDE_PATH=/usr/include/gdal
       
   170     (env) # export CPLUS_INCLUDE_PATH=/usr/include/gdal
       
   171 
       
   172 **WARNING**: you have to check also that your *libgdal* release is matching "GDAL" release given in PyAMS
       
   173 configuration file (actually 2.1.0).
       
   174 
       
   175 - for *cx_Oracle*, which is required if you use Oracle database connections, use:
       
   176 
       
   177 .. code-block:: bash
       
   178 
       
   179     (env) # export ORACLE_HOME=/usr/lib/oracle/12.1/client64
       
   180 
       
   181 These examples are given for Debian GNU/Linux. You may have to adapt configuration based on your own Linux
       
   182 distribution and packages versions.
       
   183 
       
   184 
       
   185 Environment settings
       
   186 --------------------
       
   187 
       
   188 The project generated from *pyams* scaffold is based on default Pyramid's *zodb* scaffold, but it adds:
       
   189 
       
   190 - a custom application factory, in the *webapp* directory (see :ref:`site`)
       
   191 
       
   192 - a set of directories to store runtime data, in the *var* directory; each directory contains a *README.txt* file
       
   193   which should be self-explanatory to indicate what this directory should contain, including a ZEO cache
       
   194 
       
   195 - a set of configuration files, in the *etc* directory; here are standard *development.ini* and *production.ini*
       
   196   configuration files, a ZODB configuration files (*zodb-zeo.conf*) for a ZEO client storage and two Apache
       
   197   configurations (for Apache 2.2 and 2.4) using *mod_wsgi*.
       
   198 
       
   199 Once the project have been created from the scaffold, you are free to update all the configuration files.
       
   200 
       
   201 If you need to add packages to the environment, you have to add them to the *buildout.cfg* file **AND** to the INI
       
   202 file (in the *pyramid.includes* section) before running the *buildout* another time; don't forget to add the
       
   203 requested version at the end of *buildout.cfg* file, as Buildout is not configured by default to automatically
       
   204 download the last release of a given unknown package.
       
   205 
       
   206 *development.ini* and *production.ini* files contain many commented directives related to PyAMS components. Read and
       
   207 update them carefully before initializing your application database!
       
   208 
       
   209 
       
   210 Initializing the database
       
   211 -------------------------
       
   212 
       
   213 When you have downloaded and installed all required packages, you have to initialize the database so that all
       
   214 required components are available.
       
   215 
       
   216 From a shell, just type:
       
   217 
       
   218 .. code-block:: bash
       
   219 
       
   220     (env) # ./bin/pyams_upgrade etc/development.ini
       
   221 
       
   222 This process requires that every package is correctly included into *pyramid.includes* directive from selected
       
   223 configuration file.
       
   224 
       
   225 
       
   226 Initializing Elasticsearch index
       
   227 --------------------------------
       
   228 
       
   229 If you want to use an Elasticsearch index, you have to initialize index settings and mappings; the Ingest attachment
       
   230 plug-in is also required to handle attachments correctly.
       
   231 
       
   232 Elasticsearch integration is defined through the *PyAMS_content_es* package. Configuration files are available in this
       
   233 package, for attachment pipeline, index settings and mappings:
       
   234 
       
   235 .. code-block:: bash
       
   236 
       
   237     (env) # cd /var/local/src/pyams/pyams_content_es
       
   238     (env) # curl --noproxy localhost -XDELETE http://localhost:9200/pyams (1)
       
   239     (env) # curl --noproxy localhost -XPUT    http://localhost:9200/pyams -d @index-settings.json
       
   240 
       
   241     (env) # curl --noproxy localhost -XPUT    http://localhost:9200/pyams/WfNewsEvent/_mapping -d @mappings/WfNewsEvent.json
       
   242     (env) # curl --noproxy localhost -XPUT    http://localhost:9200/pyams/WfTopic/_mapping -d @mappings/WfTopic.json
       
   243     (env) # curl --noproxy localhost -XPUT    http://localhost:9200/pyams/WfBlogPost/_mapping -d @mappings/WfBlogPost.json
       
   244 
       
   245 (1) If 'pyams' is defined as Elasticsearch index name.
       
   246 
       
   247 
       
   248 NLTK initialization
       
   249 -------------------
       
   250 
       
   251 Some NLTK (Natural Language Toolkit) tokenizers and stopwords utilities are used to index fulltext contents elements. 
       
   252 This package requires downloading and configuration of several elements which are done as follow:
       
   253 
       
   254 .. code-block:: bash
       
   255 
       
   256     (end) # ./bin/py
       
   257     >>> import nltk
       
   258     >>> nltk.download()
