Installing Resin 4 on Amazon Linux 2012.03
From Resin 4.0 Wiki
Fire up an Amazon Instance
Fire up an Amazon Instance using Amazon Linux 2012.03 (CentOS forked at 5.4 probably closest to CentOS 6 these days). Then install Resin as follows using RPM:
$ sudo rpm --import http://caucho.com/download/rpm/RPM-GPG-KEY-caucho
$ sudo yum install http://caucho.com/download/rpm/4.0.27/x86_64/resin-pro-4.0.27-1.x86_64.rpm
If the above steps confuses you, make sure you go through the Amazon EC2 tutorial and then return to this step (tutorial from Amazon WS).
If everything went well, then Resin should be installed. You can test this as follows:
$ resinctl status
Output
