I am not going to write too much about Cloudera as there is tons of information available in the world of Google.
What I am going to write here is the simple steps to setup Cloudera in Single User Mode on Oracle Linux 7.
You can download Oracle Linux 7 from https://edelivery.oracle.com/osdc/faces/Home.jspx (you need to have metalink access).
Install Oracle Linux with Server with GUI as Base Environment and Compatibility Libraries and Development Tools as Add-Ons.
I have spent couple of long hours to install Cloudera Manager with so many different errors and what not. So, Finally came out with these simple steps and scripts to setup the CDH 5 environment up and running in probably about an hour.
Used laptop configuration:
i5 processor with 16GB RAM (good luck if you have anything less than this)
OS: OL7
Steps:
01] Disable SELinux - edit /etc/selinux/config file and change the value for SELINUX to disabled and reboot and make sure "getenforce" command returns Disabled.
02] Add cloudera-scm user group to SUDO list:
#visudo
and then add the below line
%cloudera-scm ALL=(ALL) NOPASSWD:ALL
Also add below lines - believe me you are going to hit some errors if you dont.
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin
Defaults env_keep +="JAVA_HOME"
comment this line 'Defaults requiretty'
03] Add following line to /etc/pam.d/su file
session required pam_limits.so
04] Disable ipv6:
edit /etc/sysctl.conf and add the below:
# to disable IPv6 on all interfaces system wide
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
# to disable IPv6 on a specific interface (e.g., eth0, lo)
net.ipv6.conf.enp0s25.disable_ipv6 = 1
05] Make sure your /etc/host file has only this line and nothing else (because this is Single User Mode and just 127.0.0.1 is enough)
127.0.0.1 localhost
06] Now is the fun part. This is where I had to spend way too much time figuring out what causing the issue. Even though we added cloudera-scm into SUDOers list, and logged in as root, the installation part was not able to create any directories even after providing root password and password less SSH. So ended up in capturing every single folder that is needed with appropriate mode and listed in the below script. Run this script to create all required folders.

07] Once all the above folders created, Download CDH Installer:
wget https://archive.cloudera.com/cm5/installer/latest/cloudera-manager-installer.bin
08] chmod to execute:
chmod u+x cloudera-manager-installer.bin
09] Execute Installer:
./cloudera-manager-installer.bin
Follow the steps from the GUI. Once all done, you will see a notification stating that localhost:7180 will open in browser. Press the close button and you will see browser open's up with that link - dont panic if you see page not found or no connection error. Wait for couple of minutes and then refresh and continue the installation.
Un-Installing CDH:
In case if you want to wipe out (un-install) and start over CDH installation again then run the following to un-install and remove all the folders and start over from Step#6:
