WebSocket Connection Configuration

To configure websockets for Oro applications, perform the following tasks with Oro application configuration and environment:

  1. Configure a Web Server to ensure messages interaction between the WebSocket server and the clients

  2. Configure WebSocket-Related Application Parameters to provide interaction URLs for clients

  3. Run the WebSocket Server and make sure that it is always running

Configure a Web Server

Web server configuration for WebSockets connections depends on whether a site uses secure (HTTPS) or non-secure (HTTP) mode. The type of mode used will determine whether WebSocket connections use a secure (WSS) or a non-secure (WS) protocol.

Configure a Regular (WS) Connection

For non-secure connections, there is no need to adjust the Oro application web server configuration to make WebSockets work. However, using a secure connection is strongly recommended for sites in production mode.

Configure a Secure (SSL/WSS) Connection

You have to make some adjustments for a secure (WSS) connection in the web server configuration because direct backend WebSocket SSL/WSS connections are currently not supported. Also, to achieve WSS connection for your WebSocket communication on frontend, you should configure additional reverse proxy before WebSocket server.

Below you can find an example of this kind of configuration adjustment for Nginx (the recommended web server):

server {
    # This is your regular configuration for SSL connections to website
    listen 443 ssl;

    ssl_certificate_key /etc/ssl/private/;
    ssl_certificate /etc/ssl/private/;
    ssl_protocols TLSv1.2;

    # ...
    # ... Other website instructions here ...
    # ...

    # You need to add additional "location" section for Websockets requests handling
    location /ws {
        # redirect all traffic to localhost:8080;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;
        proxy_set_header X-Forwarded-Proto $scheme;

        proxy_redirect off;
        proxy_read_timeout 86400;

        # enables WS support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        # prevents 502 bad gateway error
        proxy_buffers 8 32k;
        proxy_buffer_size 64k;

        reset_timedout_connection on;

        error_log /var/log/nginx/oro_wss_error.log;
        access_log /var/log/nginx/oro_wss_access.log;

    # ...

    error_log /var/log/nginx/oro_https_error.log;
    access_log /var/log/nginx/oro_https_access.log;

In this configuration example you should replace the following values:

  • with your configured domain name.

  • ssl_certificate_key and ssl_certificate with the actual values of your active SSL certificate.

  • The ws value in the location /ws string with the value of the frontend_path option from your parameters.yml file.

  • URL and port in the proxy_pass string with the actual values of the backend_host and backend_port parameters from your parameters.yml file.

Run the WebSocket Server

OroSyncBundle provides the gos:websocket:server console command that runs the WebSocket server:

php bin/console gos:websocket:server

Since the WebSocket server must be guaranteed to run all the time for the WebSockets functionality to work, it is strongly recommended to configure a supervisor to run the WebSocket server and ensure its availability.

For example, you can install Supervisord and configure it to run the WebSocket server with following configuration instructions:

# Supervisord configuration file, e.g. /etc/supervisord.conf
command=php ./bin/console gos:websocket:server --env=prod

Logging Levels

The logging level for the websocket server can be specified with the -v|vv|vvv option of the gos:websocket:server console command.

Please note that logging levels are different in dev and prod modes by default.

Prod Mode Log Levels

  • Normal: WARNING and higher

  • Verbose (-v): NOTICE and higher

  • Very verbose (-vv): INFO and higher

  • Debug (-vvv): DEBUG and higher

Dev Mode Log Levels

  • Normal: INFO and higher

  • Verbose (-v): DEBUG and higher

The default output of log records is stdout.
