WOW!!!! Long time since I've been to his site. Here is the situation. I personally would not recommend SCADABR anymore. Mainly because they are unresponsive to English users. Unless the new Mango does not have features you are looking for, I would stay away from SCADABR. Having said that, they are very active in their development and may have features that Mango does not have. It's been a while since I looked at either new versions.
I still use SCADABR on a Fedora 13 server. Back then they had a script instead an install file for Ubuntu. I was able to modify the script to get it to work on Fedora. I sent it to SCADABR and as I said, they were very unresponsive and as you can see they moved to Ubuntu support only. This does not mean it will not work on just about any Linux box, becasue all you have to do is create a Tom Cat Server and get the WAR files installed and running on the Tom Cat Server. Make sure you get the Environment variables correct too and you should be good to go. To get the WAR of the latest SCADABR, create a virtual Ubuntu server on your Centos and install SCADABR. Then you should be able to study the install and figure out how to transfer it to Centos. That is the best advice I can give you, the rest will have to be up to you. As I said, I would probably steer away from SCADABR.
The other option would be to install it on Windows. They have an incredible installer for windows. It is a breeze. Although I completely understand if you do not want to deal with Windows and all it's License complications. I know I don't, but it can give you a good idea if you think it is worth your effort to use over Mango. I typically install SCADABR on Windows first just to see the new features, which I have not done in a long while, because my server is set up and working fine, so I haven't installed anything in a year or two.
