From ArchWiki

wallabag is a self hostable application for saving web pages.

## Installation

Install the wallabag package.

## Configuration

### PHP

Configure php to allow wallabag in `/usr/share/wallabag` to work and configure wallabag using `/etc/wallabag/parameters.yml`.

Give the wallabag user write permissions to `/usr/share/wallabag/var/cache/prod/`

A list of required php modules can be found here. The following snippet is provided for brevity.

    /etc/php/conf.d/wallabag.ini

    extension=bcmath
    extension=gd
    extension=gettext
    extension=iconv
    extension=intl
    extension=tidy

    ; database - sqlite
    ;extension=pdo_sqlite
    ;extension=sqlite3

    ; database - pgsql
    ;extension=pdo_pgsql
    ;extension=pgsql

### Wallabag

Once wallabag has been properly configured, commands must be run as the wallabag user in order to initialise the database and application state.

Tip: Ensure the desired environment is set by appending `--env=prod` to the commands.

    [wallabag]$ cd /usr/share/wallabag
    [wallabag]$ php bin/console cache:clear
    [wallabag]$ php bin/console wallabag:install

Note: When changes are made to `/etc/wallabag/parameters.yml`, the cache must be cleared.

## Database

Supported databases are:

- PostgreSQL
- MariaDB

The setup and configuration are not covered here.

## Application Server

### php-fpm

It is recommended to make a copy of `/etc/php/php-fpm.d/www.conf` and modify that. If you want to use it, you must change listen to the one which is different from `/run/php-fpm/php-fpm.sock`

    /etc/php/php-fpm.d/wallabag.conf

    [wallabag]

    user = wallabag
    group = wallabag
    listen = /run/php-fpm/php-fpm-wallabag.sock

## Web Server

### nginx

The below configuration is sourced from upstream documentation and slightly amended and modified based on custom php-fpm configure:

    /etc/nginx/example.conf

    server {
        server_name domain.tld www.domain.tld;
        root /usr/share/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:/run/php-fpm/php-fpm-wallabag.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;
        }

        # return 404 for all other php files not matching the front controller
        # this prevents access to other php files you don't want to be accessible.
        location ~ \.php$ {
            return 404;
        }

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

Generic configuration for other web servers can be found upstream.

## Troubleshooting

### Upgrading between versions

There are upgrade instructions available, dependent on the old and new versions. Generally, cache must be cleaned and database migrations performed by the wallabag user, as shown below.

Tip: Ensure the desired environment is set by appending `--env=prod` to the commands.

    [wallabag]$ cd /usr/share/wallabag
    [wallabag]$ php bin/console cache:clear
    [wallabag]$ php bin/console doctrine:migrations:migrate
