Installation

We recommend a recent unix/linux-based OS. Please check if your desired OS meets the following requirements. If not, we recommend debian (9.5 aka Stretch or later) or Ubuntu (18.04 LTS aka Bionic Beaver or later). For Giza and later at least PHP 7.1.3 is required. Note: Installation on Windows 10 with PHP 5.6 was also successfully tested, but you will need to adjust the commands in these instructions by yourself to your local Windows version equivalents.

Requirements

The following packages you should be able to install from your package manager:

  • git
  • Apache (or any other web server-software, e.g. nginx)
  • PHP (>= 7.1.3) with the following extensions installed and enabled:
    • Imagick
    • memcached (on Windows this will not work -- see later)
    • mbstring
    • gd
    • xml
    • zip
  • libapache2-mod-php (on Unix systems)
  • composer
  • PostGIS (>= 2.0)
  • PostgreSQL (>= 9.1.0)
  • ImageMagick
  • ufraw
  • memcached (extension DLL not available for Windows at the moment, see later)
  • unzip
  • php-pgsql
  • phpunit
  • nodejs
  • npm

Beside these packages we use a couple of packages you have to install on your own.

  • Laravel (PHP-Framework), currently included in the Spacialist repository, so no need to install.
  • GeoServer for hosting your own geo maps

Migration from < 0.6 (Lumen- and Angular-based releases)

There are no additional database migrations steps required. Laravel's migration command should take care of database changes. But you must update to the latest pre-0.6 release before switching to 0.6+. However, since we switched to a different code base, you have to get the new dependencies (see Download Dependencies in Package Installation). You should also check for changes in Proxy Setup and Configure Laravel. After switching to the new branch/release, you should get rid of the old dependencies. Before downloading the new dependencies, you should do the following steps:

  1. Copy .env file from lumen folder to the root folder (mv lumen/.env .env)
  2. Remove entire lumen folder (rm -rf lumen)
  3. Remove bower_components (if coming from a very old version) and node_modules (rm -rf bower_components node_modules)

Setup

Package Installation

  1. Install all the required packages. For debian-based/apt systems you can use the following command

    sudo apt-get install git apache2 libapache2-mod-php unzip php composer postgresql postgis imagemagick php-pgsql php-imagick php-memcached php-mbstring php-gd php-zip php-xml ufraw memcached phpunit nodejs npm unzip

    If the required php modules are not enabled by default, you can enable them with

    a2enmod mod_proxy
a2enmod mod_rewrite
systemctl restart apache2.service

  2. Clone This Repository

    git clone https://github.com/eScienceCenter/Spacialist

  3. Download Dependencies

    Please note: Before moving on, check your versions of composer (composer -v) and npm (npm -v). Older versions can cause problems (composer < 1.8, npm < 6.x). Update them manually if your OS has outdated versions.

    cd Spacialist
npm install
composer install

Proxy Setup

Since Laravel has a sub-folder as document root Spacialist/public, it won't work to simply copy Laravel to your webserver's root directory. One solution is to setup a proxy on the same machine and re-route all requests from /Spacialist to Laravel's public folder (e.g. /var/www/html/Spacialist/public).

  1. Enable the webserver's proxy packages and the rewrite engine

    sudo a2enmod proxy proxy_http rewrite

  2. Add a new entry to your hosts file, because your proxy needs a (imaginary) domain.

    sudo nano /etc/hosts
# Add an entry to "redirect" a domain to your local machine (localhost)
127.0.0.1 spacialist-laravel.tld # or anything you want

  3. Add a new vHost file to your apache

    cd /etc/apache2/sites-available
sudo nano spacialist-laravel.conf

    Paste the following snippet into the file:

    <VirtualHost *:80>
  ServerName spacialist-laravel.tld
  ServerAdmin webmaster@localhost
  DocumentRoot /var/www/html/Spacialist/public

  DirectoryIndex index.php

  <Directory "/var/www/html/Spacialist/public">
    AllowOverride All
    Require all granted
  </Directory>
</VirtualHost>

  4. Add the proxy route to your default vHost file (e.g. /etc/apache2/sites-available/000-default.conf)

    ProxyPass "/Spacialist" "http://spacialist-laravel.tld"
ProxyPassReverse "/Spacialist" "http://spacialist-laravel.tld"

  5. Enable the new vHost file and restart the webserver

    sudo a2ensite spacialist-laravel.conf
sudo service apache2 restart

Configure Laravel

In your config/app.php you have to adjust the APP_URL key. Replace http://localhost with the URL of your instance. E.g. https://spacialist.mydomain.tld

Laravel should now work, but to test it you need to create a .env file which stores the Laravel configuration. Inside the installation folder, create the .env file:

cd /var/www/html/Spacialist
sudo nano .env

Then paste this configuration (Please edit some of the configuration settings * to match your installation). Note: on Windows, memchached extension DLL seems unavailable. Use CACHE_DRIVER=array instead where indicated:

APP_NAME=Spacialist
APP_ENV=local
APP_DEBUG=true
APP_KEY=base64:<32bit-key> #this needs to be a 32 digit random key. Use 'php artisan key:generate'

# Your database setup. pgsql is PostgreSQL. Host, port, database, username and password need to be configured first (e.g. using your database server's commands).
DB_CONNECTION=pgsql
DB_HOST=localhost
DB_PORT=5432
DB_DATABASE=*
DB_USERNAME=*
DB_PASSWORD=*

BROADCAST_DRIVER=log
CACHE_DRIVER=memcached # on Windows memcached extension unavailable, but it seems to work with "array"
SESSION_DRIVER=file
QUEUE_DRIVER=sync

MAIL_DRIVER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
MAIL_FROM_ADDRESS=webmaster@localhost
MAIL_FROM_NAME=Webmaster

PUSHER_APP_ID=
PUSHER_APP_KEY=
PUSHER_APP_SECRET=

JWT_SECRET=ase64:<32bit-key> #this needs to be a 32 digit random key. Use 'php artisan jwt:secret'
JWT_BLACKLIST_GRACE_PERIOD=0

MIX_APP_PATH=

Send Mails

If you want to send mails to your users (e.g. password reset), you have to adjust the MAIL_* settings to match a smtp server from where you can send mails.

Configure JavaScript

Spacialist is based on several JavaScript libraries, which are bundled using Webpack (configuration is done using Laravel Mix, a webpack-wrapper for Laravel). Only the zipped releases contain the already bundled JavaScript libraries. All other users have to run webpack to bundle these libraries.

Before running webpack, you have to adjust the public path in the mix config file webpack.mix.js. To do so, set your path using the MIX_APP_PATH variable in .env file.

MIX_APP_PATH=Spacialist/subfolder/instance/

Now you can run webpack using

npm run dev
# or
npm run prod

depending on whether you want a debugging-friendly development build or an optimized production-ready build.

Migrations

After the .env file has been configured you should run the migrations to setup your database.

php artisan migrate

After your tables are set up, you need to create a new user to login and set the necessary permissions for this account. Luckily, Spacialist comes with a pre-defined account and permissions. Only thing you have to do is run

php artisan db:seed

We also have some demo data to play around with or get familiar with Spacialist. To add the demo data, run this command instead of php artisan db:seed:

php artisan db:seed --class=DemoSeeder

Now you can login with:

  • Email: admin@admin.com
  • Password: admin

Important: Since this is the same default password for all instances, we strongly recommend to change your password to something more secure. Even better is to create a new admin account with your actual email address and delete this default account.

External storage

Laravel supports different filesystems. Some of the most popular adapters:

  • AWS S3
  • Dropbox
  • Rackspace
  • SFTP
  • WebDAV

To enable one of these adapters you need to add the driver to your composer.json. For a list of available adapters, see here. To use one of the drivers add it to the config => filesystems => disks array in bootstrap/app.php. The local driver is already configured and set as default. To switch to another default adapter simply add the configuration to the disks array and set the default to the key of your added driver.

For further informations regarding the cotent of config => filesystems => disks see these documentations:

Example:
// bootstrap/app.php
<?php
....
config([
    "filesystems" => [
        'default' => 'ftp',
        'disks' => [
            'local' => [
                'driver' => 'local',
                'root' => storage_path('app'),
            ],
            'ftp' => [
                'driver'   => 'ftp',
                'host'     => 'ftp.example.com',
                'username' => 'your-username',
                'password' => 'your-password',
                // Optional FTP Settings...
                // 'port'     => 21,
                // 'root'     => '',
                // 'passive'  => true,
                // 'ssl'      => true,
                // 'timeout'  => 30,
            ]
        ],
    ],
]);
....
?>

GeoServer Installation

Additional geographical data are included through a GeoServer (see installation/linux.html).

  1. Download the GeoServer software: http://geoserver.org/release/stable/ (for Unix/Linux-based OS use the platform independent binary)
  2. Install Java Runtime sudo apt-get install openjdk-8-jre
  3. Create a new directory for GeoServer sudo mkdir /usr/share/geoserver
  4. Unpack the binary into the newly created folder unzip geoserver-2.9.1-bin.zip -d /usr/share/geoserver
  5. Set the correct folder permissions sudo chown -R www-data: /usr/share/geoserver/ and sudo chmod -R g+w /usr/share/geoserver (Please note: Your current user has to be in your webserver's group (on Ubuntu it is the group www-data), otherwise you'll get errors on startup due to missing permissions. Alternatively you can use your own username in the chown command to fix this)
  6. Change directory to /usr/share/geoserver/geoserver-2.9.1/bin
  7. Run ./startup.sh

Your server should now be ready. To check if it's running visit http://localhost:8080/geoserver Use the following credentials to login:

  • User: admin
  • Password: geoserver

Install the Importer Extension

  1. Download extension from http://geoserver.org/release/2.9.1/ (Extensions > Miscellaneous > Importer)
  2. Unzip the extension to the GeoServer's webapps lib folder unzip ~/Downloads/geoserver-2.9.1-importer-plugin.zip -d /usr/share/geoserver/geoserver-2.9.1/webapps/geoserver/WEB-INF/lib (Overwrite the commons-fileupload-1.2.1.jar file)
