Installation
============

In this section you will be able to install AgenDAV.

Prerequisites
-------------

AgenDAV |release| requires the following software to be installed:

* A CalDAV server (developed mainly with `DAViCal <http://www.davical.org/>`_
* A web server
* PHP >= 5.3.0
* PHP mbstring extension
* PHP cURL extension
* MySQL > 5.1 or PostgreSQL >= 8.1

Downloading AgenDAV and uncompressing
-------------------------------------

AgenDAV |release| can be obtained at `AgenDAV official webpage
<http://agendav.org>`_, but you can use GitHub to download latest version.
Have a look at `<http://github.com/adobo/agendav>`_.

Uncompress it using ``tar``::

 $ tar xzf adobo-agendav-...tar.gz
 $ cd adobo-agendav-.../

Database and tables
-------------------

AgenDAV requires a database to store some information. Supported RDBMs are
MySQL and PostgreSQL.

First of all you have to create a user and a database for that user.

Second, you'll have to create initial AgenDAV tables using provided SQL
files inside ``sql/`` directory.

Last step is applying database upgrades to initial database tables.

Steps 1&2: MySQL
****************
Create an user in MySQL like this::

 $ mysql --default-character-set=utf8 -uroot -p
 Enter password: 
 [...]
 mysql> GRANT ALL PRIVILEGES ON agendav.* TO agendav@localhost IDENTIFIED BY 'yourpassword'
 mysql> CREATE DATABASE agendav CHARACTER SET utf8 COLLATE utf8_general_ci;
 mysql> FLUSH PRIVILEGES;
 mysql> ^D

And then run the initial schema creation file::

 $ mysql --default-character-set=utf8 -uagendav \
   -p agendav < sql/mysql.schema.sql
 Enter password:
 $

Note the UTF8 parts on the previous commands. If you don't specify them you
will have some issues with special characters.

Steps 1&2: PostgreSQL
*********************

Use the special ``postgres`` system user to manage your installation. You
can add a new user and a new database the following way::

 # su postgres
 $ psql
 postgres=# CREATE USER agendav WITH PASSWORD 'somepassword';
 postgres=# CREATE DATABASE agendav ENCODING 'UTF8';
 postgres=# GRANT ALL PRIVILEGES ON DATABASE agendav TO agendav;
 postgres=# \q
 $ exit

Then you have to edit the file ``pg_hba.conf``, which is usually located at
``/var/lib/pgsql/``. Add the following line before other definitions::

 # TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD
 local   agendav     agendav     trust

After that just restart PostgreSQL and load the initial schema::

 $ psql -U agendav agendav < sql/pgsql.schema.sql


Step 3: Apply latest database schema
************************************

Initial database structure created with `*.sql` files provides only a base
structure for AgenDAV. It has to be modified to apply latest release
changes. To do this, follow instructions on :ref:`dbupgrade`.


Configuring Apache web server
-----------------------------

Apache has to be configured to point to ``web/public`` directory, using its
own VirtualHost or just an Alias.

Example using a dedicated virtualhost::

 <VirtualHost 1.2.3.4:443>
  ServerAdmin admin@email.host
  DocumentRoot /path/to/agendav/web/public
  ServerName agendav.host
  ErrorLog logs/agendav_error_log
  CustomLog logs/agendav_access_log common
 </VirtualHost>

Example using the Alias directive::

 Alias /agendav /path/to/agendav/web/public

.. note::
   Make sure that you have the following PHP settings *disabled*:

   * ``magic_quotes_gpc``
   * ``magic_quotes_runtime``

Other web servers
*****************

AgenDAV should work on all other web server software if they support PHP
scripts, but this is untested.

Configure AgenDAV
-----------------

Now you can proceed to configure AgenDAV following the :doc:`configuration`
section.
