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 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)

wallabag uses a large number of 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.

Install Composer:

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

You can find specific instructions here:

To install wallabag itself, you must run the following commands:

git clone https://github.com/wallabag/wallabag.git
cd wallabag
git checkout 2.0.5
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

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.

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:

wget http://wllbg.org/latest-v2-package && tar xvf latest-v2-package

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 to our repository on Docker Hub to have more information.

Command to launch container

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 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.

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 php bin/console server:run --env=prod 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 php bin/console server:run --env=prod 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 could be not 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:

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

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:

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
