PHPPeerServer

PHP Socket.io server for WebRTC signaling.

Client: https://github.com/jsanahuja/peer-client

Demo: https://peer-demo.sowecms.com/

Install

Clone both client and server and install dependencies.

git clone https://github.com/jsanahuja/php-peer-server.git
git clone https://github.com/jsanahuja/peer-client.git
cd php-peer-server 
composer install
cd ../peer-client
npm install
npm run build

Create your server configuration file

cd ../php-peer-server
cp config.example.php config.php

Generate your Keychain private key:

php make_keychain.php

Result example: 1949e2278ea5767099e592ae8dd15677ecf851efd177a1f0fb1d44e8e79231f5

Place the result in the constant KEYCHAIN_PK defined in the config.php file we just created. Set also the absolute path to your CERT_CA and CERT_KEY files. You can play with the other constant values but it should be good to go. Note that if you want to change the PORT you will have to change it in the peer-client too.

Start the server as a daemon

php server.php start -d

Do not forget to open/whitelist the PORT or the server won't be accessible. For example with firewalld you would do:

firewall-cmd --zone=public --permanent --add-port=8999/tcp
firewall-cmd --reload

Note: The HTTP server should be pointing to the peer-client folder.
