PHP Ratchet Websocket: Establishing Secure SSL Connections

Problem Scenario

In a PHP Ratchet chat server, attempts to connect via SSL using a WebSocket have been unsuccessful. The existing code connects seamlessly via ws, but upgrading to wss results in connection issues.

Solution

To establish secure SSL connections with PHP Ratchet websockets, the following steps are necessary:

1. Enable Required Apache Modules: If using Apache web server, ensure that the following modules are enabled in the httpd.conf file:

   • mod_proxy.so
   • mod_proxy_wstunnel.so

2. Configure httpd.conf: Add the following setting to the httpd.conf file:

   ProxyPass /wss2/ ws://ratchet.mydomain.org:8888/

   Copy after login

3. Updated JavaScript Call: In the JavaScript code, replace the original connection URL with the following format:

   var ws = new WebSocket("wss://ratchet.mydomain.org/wss2/NNN");

   Copy after login
4. Restart Apache Web Server: Restart Apache to apply the new settings. Ensure that the Ratchet worker is running before making these changes.
