Taking advantage of the Amazon EC2 free year long trial, I installed RapidAnalytics in their Cloud on a micro instance running Ubuntu 10.10 with MySQL. Port 8080 needs to be opened in the instance firewall to allow incoming requests to the RapidAnalytics web page.
Installation of the Ubuntu desktop, a VNC server and Java was the time consuming part. Note that installing Java does not work on a micro instance; there is a known error. The workround is to run on a small instance and then install Java in that environment. Having done that, the image can be saved and re-run on a micro instance.
The memory available in the micro instance is insufficient for the default JBoss settings. Reducing this to 512M allows everything to start but after 30 minutes it does not run properly with many timeout like errors.
Sad conclusion: the micro instance is too small - this is a shame since it means free Cloud practice is not possible.
Changing to a small instance allow things to start and after about 5 minutes, RapidAnalytics starts OK and is usable. This costs money - not a lot - but enough for my mean streak to kick in. A medium instance would presumably start more quickly - it would cost a bit more so I didn't try it.
The IP connectivity to allow the server to be found so that a local RapidMiner client can use it is the next step although money is likely to be required to assign an IP address that can be seen on the Internet.
Conclusion: RapidAnalytics will work in the Cloud but some cost conscious people will choose to install and play on local machines.
Installation on a laptop running XP SP3 and SQL Server is also OK as is installation on a 64 bit laptop running Windows 7 enterprise with MySQL. Note that some SQL Server components steal port 8080 necessitating a change to the JBoss port to something like 8081 in the server.xml file contained in the folder rapidAnalytics\rapidanalytics\server\default\deploy\jbossweb.sar.
Next steps will be to find a way to backup a RapidAnalytics installation and restore on a different machine.

Hello Andrew,
ReplyDeleteI had RapidAnalytics running on my local Machine for almost three months and now I would like to install it in the Amazon cloud, on a small instance running Amazon linux AMI.
I read your instructions and I followed the RapidAnalytics manual to install RapidAnalytics on Amazon ec2 server with no success until now.
What I've done so far:
- I installed RapidAnalytics from command line with the no-gui mode using the installer .xml file.
I left blank the "server_service_linux_variant" and "server_service_id" since I don't know what to use for Amazon linux AMI.
- The installation goes well and it is successful.
- Starting RapidAnalytics (./run.sh -b 0.0.0.0) I get many errors but at the end I get "JBossAS [6.0.0.Final "Neo"] Started"
- I tried installing on different ports in case port 8080 was occupied by another application.
Do you have any suggestions?
I would really appreciate any help.
Thanks
Nikos
Hello Nikos
ReplyDeletePort 8080: is that open
If so then this post is helpful
http://rapid-i.com/rapidforum/index.php/topic,3737.0.html
in particular look for the property
webServiceHost and change its value to jbossws.undefined.host
it might help (although it might not)
regards,
Andrew
Hi Andrew,
ReplyDeleteYes, port 8080 is open.
I will read and try what you suggested.
Thanks for the quick reply.
