Feel free to use path A as well! It is by far the simplest approach to setup and configuration so that you can get into using the platform quickly.
The path B approach lets you manage the installation manually using packages, and would be what you want to do for a production deployment that you intend to run long term.
If you have previously attempted install, search for "uninstall" in the installation guide in the docs (top left of docs pages to search) and it will give you the cleanup steps to apply to your previous installation attempts.
RHEL 6.4 is fine to use 6.5 is supported as well, the actual OS, database, and JDK requirements are listed in the sections around the link I gave for the single user mode discussion as well.
Keep us posted on your progress, feel free to start a new topic to address the specific issue you see.

I can document the process for CentOS if you like. It's pretty much the same with RedHat as well. Only difference is the repo and versions.
Let me know if you want it documented then I'll post it somewhere for you.

Requirements for installation:
http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/installation_reqts.html
Step by step instructions for install based on linux distro
Path A uses our simple binary installer, which is OK for lab/POC type setup. Path B is the preferred method when planning installation for a production or production release testing environment. The simple path A installer installs and configures embedded database instances that may not be appropriate for the long term management of a production environment.

Also question - are you saying "single user mode" or "single node cluster", as they are different things related to the install.
If you are doing a single node cluster the one additional step would be to set the block replication factor for HDFS to 1 during setup of CDH services.

the prolem is that when I choose "Single User Mode" checkbox while installing CDH I get following error "/api/v8/cm/config { }" I don't know what is this.

This page runs through the requirements for a system and what needs to be done to prepare for single user mode install. If you dont have specific security requirements to install as a user other that root, I would suggest simplifying your approach ot the install. If you must use a non-root user to install, then you must prepare things based on these steps.
