Openfire Cluster behind EC2 Load Balancer


#1

Hello There,

I have a two node cluster setup of Openfire using same database on two EC2 nodes (say App Server A and App Server B).

UI application instances are running on two EC2 Nodes (say Web Server A and Web Server B), chat clients are using BOSH for HTTP-Binding to connect to Openfire.

I have two load balancers, say LB1 and LB2, below picture depicts the setup:

I have enabled all the required ports/traffic from security groups, but the HTTP-Bind requests get blocked, displaying “blocked:mixed-content” in network section.

Can someone suggest what else do I need check, implement?


#2

You might be trying to access both HTTPS as well as HTTP endpoints. Try using just one of those.

As an aside: make sure that your LB2 uses some kind of stick sessions! You want the same client to end up with the same instance of Openfire for every request.


#3

I have enable SSL on openfire, configured sticky session on EC2 Load balancers.

Now from UI application for http-bind requests, it is able to connect to openfire server but for a request which fetches messages it gives 404 ‘invalid SID’.

Any specific area which I need to explore?


#4

I tried turning down one openfire cluster node, so that the bind requests propagate to the same openfire server.

User shows online status when checked from openfire, but then one of the bind request fails with 504 ‘Bad Gateway’ error.

Can some one suggest a way out of it? Or any suggestions?
