Install wallabag
|
|
================
|
|
|
|
Requirements
|
|
------------
|
|
|
|
wallabag is compatible with PHP >= 5.5, including PHP 7.
|
|
|
|
.. note::
|
|
|
|
To install wallabag easily, we provide a ``Makefile``, so you need to have the ``make`` tool.
|
|
|
|
wallabag uses a large number of PHP libraries in order to function. These libraries must be installed with a tool called Composer. You need to install it if you have not already done so and be sure to use the 1.2 version (if you already have Composer, run a ``composer selfupdate``).
|
|
|
|
Install Composer:
|
|
|
|
::
|
|
|
|
curl -s http://getcomposer.org/installer | php
|
|
|
|
You can find specific instructions `here <https://getcomposer.org/doc/00-intro.md>`__.
|
|
|
|
You'll also 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
|
|
- php-bcmath
|
|
|
|
wallabag uses PDO to connect to the database, so you'll need one of the following:
|
|
|
|
- pdo_mysql
|
|
- pdo_sqlite
|
|
- pdo_pgsql
|
|
|
|
and its corresponding database server.
|
|
|
|
Installation
|
|
------------
|
|
|
|
On a dedicated web server (recommended way)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To install wallabag itself, you must run the following commands:
|
|
|
|
::
|
|
|
|
git clone https://github.com/wallabag/wallabag.git
|
|
cd wallabag && make install
|
|
|
|
To start PHP's build-in server and test if everything did install correctly, you can do:
|
|
|
|
::
|
|
|
|
make run
|
|
|
|
And access wallabag at http://yourserverip:8000
|
|
|
|
.. tip::
|
|
|
|
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 at `Symfony documentation <http://symfony.com/doc/current/cookbook/configuration/external_parameters.html>`__.
|
|
|
|
On a shared hosting
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
We provide a package with all dependencies inside.
|
|
The default configuration uses SQLite for the database. If you want to change these settings, please edit ``app/config/parameters.yml``.
|
|
|
|
We already created a user: login and password are ``wallabag``.
|
|
|
|
.. caution:: With this package, wallabag doesn't check for mandatory extensions used in the application (theses checks are made during ``composer install`` when you have a dedicated web server, see above).
|
|
|
|
Execute this command to download and extract the latest package:
|
|
|
|
.. code-block:: bash
|
|
|
|
wget http://wllbg.org/latest-v2-package && tar xvf latest-v2-package
|
|
|
|
You will find the `md5 hash of the latest package on our website <https://www.wallabag.org/pages/download-wallabag.html>`_.
|
|
|
|
Now, read the following documentation to create your virtual host, then access your wallabag.
|
|
If you changed the database configuration to use MySQL or PostgreSQL, you need to create a user via this command ``php bin/console wallabag:install --env=prod``.
|
|
|
|
Installation with Docker
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
We provide you a Docker image to install wallabag easily. Have a look at our repository on `Docker Hub <https://hub.docker.com/r/wallabag/wallabag/>`__ for more information.
|
|
|
|
Command to launch container
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. code-block:: bash
|
|
|
|
docker pull wallabag/wallabag
|
|
|
|
Virtual hosts
|
|
-------------
|
|
|
|
Configuration 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.
|
|
|
|
Configuration on Nginx
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Assuming you installed 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.
|
|
|
|
.. tip::
|
|
|
|
When you want to import large files into wallabag, you need to add this line in your nginx configuration ``client_max_body_size XM; # allows file uploads up to X megabytes``.
|
|
|
|
Configuration on lighttpd
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Assuming you install wallabag in the ``/var/www/wallabag`` folder, here's the recipe for wallabag (edit your ``lighttpd.conf`` file and paste this configuration into it):
|
|
|
|
::
|
|
|
|
server.modules = (
|
|
"mod_fastcgi",
|
|
"mod_access",
|
|
"mod_alias",
|
|
"mod_compress",
|
|
"mod_redirect",
|
|
"mod_rewrite",
|
|
)
|
|
server.document-root = "/var/www/wallabag/web"
|
|
server.upload-dirs = ( "/var/cache/lighttpd/uploads" )
|
|
server.errorlog = "/var/log/lighttpd/error.log"
|
|
server.pid-file = "/var/run/lighttpd.pid"
|
|
server.username = "www-data"
|
|
server.groupname = "www-data"
|
|
server.port = 80
|
|
server.follow-symlink = "enable"
|
|
index-file.names = ( "index.php", "index.html", "index.lighttpd.html")
|
|
url.access-deny = ( "~", ".inc" )
|
|
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )
|
|
compress.cache-dir = "/var/cache/lighttpd/compress/"
|
|
compress.filetype = ( "application/javascript", "text/css", "text/html", "text/plain" )
|
|
include_shell "/usr/share/lighttpd/use-ipv6.pl " + server.port
|
|
include_shell "/usr/share/lighttpd/create-mime.assign.pl"
|
|
include_shell "/usr/share/lighttpd/include-conf-enabled.pl"
|
|
dir-listing.activate = "disable"
|
|
|
|
url.rewrite-if-not-file = (
|
|
"^/([^?]*)(?:\?(.*))?" => "/app.php?$1&$2",
|
|
"^/([^?]*)" => "/app.php?=$1",
|
|
)
|
|
|
|
Rights access to the folders of the project
|
|
-------------------------------------------
|
|
|
|
Test environment
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
When we just want to test wallabag, we just run the command ``make run`` to start our wallabag instance and everything will go smoothly because the user who started the project can access to the current folder naturally, without any problem.
|
|
|
|
Production environment
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
As soon as we use Apache or Nginx to access to our wallabag instance, and not from the command ``make run`` to start it, we should take care to grant the good rights on the good folders to keep safe all the folders of the project.
|
|
|
|
To do so, the folder name, known as ``DocumentRoot`` (for apache) or ``root`` (for Nginx), has to be absolutely accessible by the Apache/Nginx user. Its name is generally ``www-data``, ``apache`` or ``nobody`` (depending on linux system used).
|
|
|
|
So the folder ``/var/www/wallabag/web`` has to be accessible by this last one. But this may not be enough if we just care about this folder, because we could meet a blank page or get an error 500 when trying to access to the homepage of the project.
|
|
|
|
This is due to the fact that we will need to grant the same rights access on the folder ``/var/www/wallabag/var`` like those we gave on the folder ``/var/www/wallabag/web``. Thus, we fix this problem with the following command:
|
|
|
|
.. code-block:: bash
|
|
|
|
chown -R www-data:www-data /var/www/wallabag/var
|
|
|
|
It has to be the same for the following folders
|
|
|
|
* /var/www/wallabag/bin/
|
|
* /var/www/wallabag/app/config/
|
|
* /var/www/wallabag/vendor/
|
|
* /var/www/wallabag/data/
|
|
|
|
by entering
|
|
|
|
.. code-block:: bash
|
|
|
|
chown -R www-data:www-data /var/www/wallabag/bin
|
|
chown -R www-data:www-data /var/www/wallabag/app/config
|
|
chown -R www-data:www-data /var/www/wallabag/vendor
|
|
chown -R www-data:www-data /var/www/wallabag/data/
|
|
|
|
otherwise, sooner or later you will see these error messages:
|
|
|
|
.. code-block:: bash
|
|
|
|
Unable to write to the "bin" directory.
|
|
file_put_contents(app/config/parameters.yml): failed to open stream: Permission denied
|
|
file_put_contents(/.../wallabag/vendor/autoload.php): failed to open stream: Permission denied
|
|
|
|
Additional rules for SELinux
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
If SELinux is enabled on your system, you will need to configure additional contexts in order for wallabag to function properly. To check if SELinux is enabled, simply enter the following:
|
|
|
|
``getenforce``
|
|
|
|
This will return ``Enforcing`` if SELinux is enabled. Creating a new context involves the following syntax:
|
|
|
|
``semanage fcontext -a -t <context type> <full path>``
|
|
|
|
For example:
|
|
|
|
``semanage fcontext -a -t httpd_sys_content_t "/var/www/wallabag(/.*)?"``
|
|
|
|
This will recursively apply the httpd_sys_content_t context to the wallabag directory and all underlying files and folders. The following rules are needed:
|
|
|
|
+-----------------------------------+----------------------------+
|
|
| Full path | Context |
|
|
+===================================+============================+
|
|
| /var/www/wallabag(/.*)? | ``httpd_sys_content_t`` |
|
|
+-----------------------------------+----------------------------+
|
|
| /var/www/wallabag/data(/.*)? | ``httpd_sys_rw_content_t`` |
|
|
+-----------------------------------+----------------------------+
|
|
| /var/www/wallabag/var/logs(/.*)? | ``httpd_log_t`` |
|
|
+-----------------------------------+----------------------------+
|
|
| /var/www/wallabag/var/cache(/.*)? | ``httpd_cache_t`` |
|
|
+-----------------------------------+----------------------------+
|
|
|
|
After creating these contexts, enter the following in order to apply your rules:
|
|
|
|
``restorecon -R -v /var/www/wallabag``
|
|
|
|
You can check contexts in a directory by typing ``ls -lZ`` and you can see all of your current rules with ``semanage fcontext -l -C``.
|
|
|
|
If you're installing the preconfigured latest-v2-package, then an additional rule is needed during the initial setup:
|
|
|
|
``semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/wallabag/var"``
|
|
|
|
After you successfully access your wallabag and complete the initial setup, this context can be removed:
|
|
|
|
::
|
|
|
|
semanage fcontext -d -t httpd_sys_rw_content_t "/var/www/wallabag/var"
|
|
retorecon -R -v /var/www/wallabag/var
|
