When attempting to start Nexus 2.11.3 i.e. ./bin/nexus console it attempts 5 times and fails. The error log set at debug level output is not intuitive as to where to even start with trouble-shooting. Perhaps others are familiar with some of the output. BTW. I run JAVA JDK 1.7u1.

You need to upgrade to a newer version of Java 7 or even better Java 8. Update 1 of Java 7 had numerous issues and among other things does not work with Nexus.
Also note that only Oracle JVM is officially supported.
Btw here are the full Nexus sytem requirements in detail:
