Install wallabag
================

Requirements
------------

wallabag is compatible with PHP >= 5.5, including PHP 7.

You'll need the following extensions for wallabag to work. Some of these may already activated in your version of PHP, so you may not have to install all corresponding packages.

- php-session
- php-ctype
- php-dom
- php-hash
- php-simplexml
- php-json
- php-gd
- php-mbstring
- php-xml
- php-tidy
- php-iconv
- php-curl
- php-gettext
- php-tokenizer

wallabag uses PDO to connect to database, so you'll need one of:

- pdo_mysql
- pdo_sqlite
- pdo_pgsql

and it's corresponding database server.

Installation
------------

wallabag uses a big number of libraries in order to function. These libraries must be installed with a tool called Composer. You need to install it if you don't already have.

Install Composer:

::

    curl -s http://getcomposer.org/installer | php

You can find specific instructions `here <https://getcomposer.org/doc/00-intro.md>`__:

To install wallabag itself, you must run these two commands:

::

    git clone https://github.com/wallabag/wallabag.git
    cd wallabag
    git checkout 2.0.1
    SYMFONY_ENV=prod composer install --no-dev -o --prefer-dist
    php bin/console wallabag:install --env=prod

To start php's build-in server and test if everything did install correctly, you can do:

::

    php bin/console server:run --env=prod

And access wallabag at http://yourserverip:8000

.. note::

    To define parameters with environment variables, you have to set these variables with ``SYMFONY__`` prefix. For example, ``SYMFONY__DATABASE_DRIVER``. You can have a look to the `Symfony documentation <http://symfony.com/doc/current/cookbook/configuration/external_parameters.html>`__.

Installing on Apache
--------------------

Assuming you install wallabag in the /var/www/wallabag folder and that you want to use php as an Apache module, here's a vhost for wallabag:

::

    <VirtualHost *:80>
        ServerName domain.tld
        ServerAlias www.domain.tld

        DocumentRoot /var/www/wallabag/web
        <Directory /var/www/wallabag/web>
            AllowOverride None
            Order Allow,Deny
            Allow from All

            <IfModule mod_rewrite.c>
                Options -MultiViews
                RewriteEngine On
                RewriteCond %{REQUEST_FILENAME} !-f
                RewriteRule ^(.*)$ app.php [QSA,L]
            </IfModule>
        </Directory>

        # uncomment the following lines if you install assets as symlinks
        # or run into problems when compiling LESS/Sass/CoffeScript assets
        # <Directory /var/www/wallabag>
        #     Options FollowSymlinks
        # </Directory>

        # optionally disable the RewriteEngine for the asset directories
        # which will allow apache to simply reply with a 404 when files are
        # not found instead of passing the request into the full symfony stack
        <Directory /var/www/wallabag/web/bundles>
            <IfModule mod_rewrite.c>
                RewriteEngine Off
            </IfModule>
        </Directory>
        ErrorLog /var/log/apache2/wallabag_error.log
        CustomLog /var/log/apache2/wallabag_access.log combined
    </VirtualHost>

After reloading or restarting Apache, you should now be able to access wallabag at http://domain.tld.

Installing on Nginx
-------------------

Assuming you install wallabag in the /var/www/wallabag folder, here's the recipe for wallabag :

::

    server {
        server_name domain.tld www.domain.tld;
        root /var/www/wallabag/web;

        location / {
            # try to serve file directly, fallback to app.php
            try_files $uri /app.php$is_args$args;
        }
        location ~ ^/app\.php(/|$) {
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_split_path_info ^(.+\.php)(/.*)$;
            include fastcgi_params;
            # When you are using symlinks to link the document root to the
            # current version of your application, you should pass the real
            # application path instead of the path to the symlink to PHP
            # FPM.
            # Otherwise, PHP's OPcache may not properly detect changes to
            # your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
            # for more information).
            fastcgi_param  SCRIPT_FILENAME  $realpath_root$fastcgi_script_name;
            fastcgi_param DOCUMENT_ROOT $realpath_root;
            # Prevents URIs that include the front controller. This will 404:
            # http://domain.tld/app.php/some-path
            # Remove the internal directive to allow URIs like this
            internal;
        }

        error_log /var/log/nginx/wallabag_error.log;
        access_log /var/log/nginx/wallabag_access.log;
    }

After reloading or restarting nginx, you should now be able to access wallabag at http://domain.tld.

.. note::

    When you want to import large file into wallabag, you need to add this line in your nginx configuration ``client_max_body_size XM; # allows file uploads up to X megabytes``.
