To DIYiotServer παρέχει:

• Network-enabled Arduino, wireless ή ethernet, έχει επίσης λειτουργικά την δυνατότητα σύνδεσης σε δίκτυο 3G/GPRS
• Over-the-air/on-the-fly programming

DIYiotServer provides a REST API and tools for creating network-enabled Arduino projects.

DIYiotServer provides:

• Network-enabled Arduino, wireless or over ethernet, can also connect to 3G/GPRS networks
• Over-the-air/on-the-fly programming
• Online monitoring & real-time data streaming
• REST API for creating UIs for the Web or smartphones

• Apache - The Apache HTTP Server ("httpd") (http://httpd.apache.org)
  - you can use lighttpd or nginx but is not tested yet

• PHP with PDO (http://php.net)

  • PHP is a popular general-purpose scripting language that is especially suited to web development.
  • PDO The PHP Data Objects extension defines a lightweight, consistent interface for accessing databases in PHP.
    PDO provides a data-access abstraction layer, which means that, regardless of which database you're using, you use the same functions to issue queries and fetch data.

• sqlite3 (http://www.sqlite.org)

  • SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.
    Alternative
  • In fact that this project use PDO you can also use any of this databases systems
    See http://php.net/manual/en/pdo.drivers.php

• Ratchet - WebSockets for PHP (http://socketo.me)

• React - Event-driven, non-blocking I/O with PHP (http://reactphp.org/)

• ZeroMQ - Carries messages across inproc, IPC, TCP, TPIC, multicast (http://zeromq.org)

• HAProxy - The Reliable, High Performance TCP/HTTP Load Balancer (http://www.haproxy.org)

• Autobahn|JS - provides an open-source implementation of The Web Application Messaging Protocol (WAMP) (http://autobahn.ws/js)

  • Autobahn is used in https://github.com/diyiot-tools/DIYiotWebClient.
    See https://github.com/diyiot-tools/DIYiotWebClient/blob/master/example-websocket.html

Optional

• Supervisor - A Process Control System (http://supervisord.org)

• API Documentation
  See swagger-ui and swagger-php.

You can use the DIYiotServer code as is, no need to build or recompile. Just clone this repo and use the files in the web folder.

Follow these steps to set up the website in the Apache web server:

Edit the apache configuration file (e.g. /etc/httpd/conf/httpd.conf in CentOS):

DocumentRoot /var/www/html/web
ServerName example.com

<Directory /var/www/html/web>
    Options -Indexes
    AllowOverride All
    Require all granted
</Directory>

Generate SSL keys:

cd ssh/
./create_rsa_key.sh

In tools/insert-testdata_db.php, replace all occurrences of ../ssh/pubkey.pem and ../ssh/privkey.pem, with your file names:

$publicKey  = file_get_contents('../ssh/pubkey.pem');
$privateKey = file_get_contents('../ssh/privkey.pem');

Insert test data and and check the generated tables:

cd tools/
php ./rebuild_db.php
php ./insert-testdata_db.php
cd ../db
sqlite3 oauth.sqlite
.tables
.quit

Edit web/server/system/core.php:

$_dbfile = 'path_to_db_file'; # (by default oauth.sqlite)
$_apihost="https://your_url"; # (your FQDN)
$sshhome="path_to_ssh_dir";   # (dir that contains the devices keys)

More info how to do this:

• http://stackoverflow.com/questions/8021/allow-user-to-set-up-an-ssh-tunnel-but-nothing-else
• http://www.gnu.org/software/bash/manual/html_node/The-Restricted-Shell.html
• https://wiki.archlinux.org/index.php/Secure_Shell

Edit client/myhost.php:

$host="url";            # (your FQDN)
$username="username";   # (set a username)
$password="password";   # (set a password)

Run php client/client-gettoken.php.

If you see something like this, then your application is ready:

array(4) {
  ["access_token"]=>
  string() "token"
  ["expires_in"]=>
  int(3600)
  ["token_type"]=>
  string(6) "bearer"
  ["scope"]=>
  string(15) "test_admin main"
}

See the examples in the client directory.

Edit ws/src/MyApp/Config.php:

$_dbfile = 'path_to_db_file';   # (by default oauth.sqlite)
$_apihost="https://your_url";   # (your FQDN)
$_wssusername='wssusername';    # (same as client/myhost.php)
$_wsspassword='wsspassword';    # (same as client/myhost.php)

Change the 127.0.1.1 line to your new wss/API service, by editing /etc/hosts and appending verifytoken to the localhost entry. For example:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 verifytoken

If the https API is installed on another host, then put here the IP of the host, for example:

192.168.0.10   verifytoken

Run it with:

php ws/ws.php

Happy Coding :-)
