--------------------------------------------
Hi [~mike.jumper],
Well, I'm hoping to first attach a remote debugger to my tomcat server to try
and help fix a bug that I reported related to a balancing connection group.
Once, I'm a bit more familiar with the code base I was thinking about trying to
help with this feature request.
I'm interested in the memcached option that Nick was talking about "Use some
sort of shared/distributed caching mechanism (Hazelcast, memcached come to
mind) where multiple systems could access the data, without actually writing it
to a database."
I'm rather new to the idea and structure of your project and memcached, so I'm
sure there would be a large learning curve on my end. However, I see this
feature request is 2 years+ out so maybe it is something I can accomplish with
a bit of work.
I have access to some code examples of using memcached using spymemcached as a
dependency inside maven from "Getting Started with Memcached" on packtpub.
Their examples look like you'd need to run some type of controller container.
So, that is the route I was initially planning to utilize, but I'm open to
directions and trying to help form what you're looking to accomplish.
> HA in Guacamole
> ---------------
>
> Key: GUACAMOLE-283
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-283
> Project: Guacamole
> Issue Type: New Feature
> Components: guacamole-client, guacamole-server
> Reporter: Thiago dos Santos Nunes
> Priority: Minor
>
> A great feature for guacamole would be high availability both on the client
> (mainly) and on the server.
> In the client the ideal would be to be able to at least be able to block by
> the number of simultaneous connections even having an environment with
> several vms or containers.
> I currently have an environment with 3 guacamole servers with Tomcat 8
> running behind a HAPROXY. But I lose the block by simultaneous connection (I
> charge my clients for simultaneous connection) and I can not give up having
> more than one vm, because if one falls I lose all. It would also be great if
> the user does not need to log in again if they go to another server (session
> permanence). Today I work with hundreds of simultaneous users from different
> places.
> It would also be very good to be able to separate the client from the server
> and be able to work on HA on the server as well.
> My Environment:
> 3x Guacamole server and client: 0.9.12
> Database and Authentication: MySQL (another vm)
> File Server: SFTP (another vm)
> I alread commented this on:
