The following concise guide for installing SEP 12.1.6 on Red Hat linux. In this case, the RHEL version was 7.2 but it applies to all linux platforms.
I prefer the RPM version of the JDK because it will run immediately and automatically after the download completes. Alternatively, the command line to manually install the rpm version is: rpm -i <filename.rpm>
/usr/java/<java build #>/jre/lib/security/
The installation should complete, barring any other issues.
