Operating System pre-requisites to install Couchbase at Linux Red Hat

Browising the doc about OS prereq at : http://developer.couchbase.com/documentation/server/4.1/install/pre-install.html.

I don’t see any list of packages required to install successfully CouchBase.
Which is the necesary OS base , by example using Oracle Enterprise Linux?
I’d like to install only the minimum necesarys packages to install Couchbase.

Another question:
Is there pdf version of Couchbase doc to use offline?

Many thanKS
Best regards
