How to use it¶ ↑
Requirements¶ ↑
-
Ruby 2.1.2 or greater
-
Redis
Server setup¶ ↑
Most linux distributions have by defualt a very low open files limit. In order to sustain more than 1024 ( default ) connections, you need to apply the following changes to your system: Add to /etc/sysctl.conf
:
fs.file-max = 50000
Add to /etc/security/limits.conf
:
* hard nofile 50000 * soft nofile 50000 * hard nproc 50000 * soft nproc 50000
$ kalerbr-pusher --app_key 765ec374ae0a69f4ce44 --secret your-pusher-secret
If all went to plan you should see the following output to STDOUT
kalebr-pusher API server listening on port 4567 kalebr-pusher WebSocket server listening on port 8080
Modifying your application code to use the Kalebr service¶ ↑
... Pusher.host = 'kalebr.example.com' Pusher.port = 4567
You will also need to do the same to the Pusher JavaScript client in your client side JavaScript, e.g
<script type="text/javascript"> var pusher = new Pusher('#{Pusher.key}', { wsHost: "0.0.0.0", wsPort: "8080", wssPort: "8080", enabledTransports: ['ws', 'flash'] }); </script>
Of course you could proxy all requests to ws.example.com
to port 8080 of your kalerbr-pusher node and api.example.com
to port 4567 of your kalerbr-pusher node for example, that way you would only need to set the host property of the Pusher client.
