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

 

http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/installation_installati...

 

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 single user mode installation has a number of pre installation requirements, what step are you on within the docs at this point?

What I did:
1. I installed CentOS 6.4 (DESKTOP) on Windows with dual boot. Disabled
Selinux and Iptables.
2. I downloaded Cloudera Manager Latest 5.3.2 from official website
(Express version)
3. Then changed rights to Cloudera installer and started installation .
4. It started the process of downloading and configuring
5. Then dialog box opened "installation success" and I opened
localhost:7180 from browser from where I choose free install of cloudera
manager, then in hosts I typed my host IP address clicked continue, then I
selected parcels and choose to install JDK,

up to here everything was fine

here started the problem:
6. I checked "Single User Mode" checkbox and clicked continue and it gave
me error "/api/v8/cm/config { }";
7. I tried also installing without checking "Single User Mode" Still at the
end of installation it gives me error .

I looked many instructions and tried many things, but with no result.

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.
