Perform the following steps to deploy DPOD on a Pre-installed CentOS / RHEL :

Red Hat Enterprise Linux Server release 7.7-7.8
CentOS version 7.7-7.8

This video demonstrates how to install DPOD Non-Appliance mode on RHEL 7.8 operating system. Use it just as a demonstration, as it is not kept up-to-date with every change in the process. When installing DPOD, you should follow the procedure provided below.

Prerequisites

Make sure to follow Prepare Pre-Installed Operating System.

Execute the CEF file

Download the CEF (Compressed Executable Format) file and copy it to /tmp directory.
Make sure /tmp is not mounted with noexec flag (e.g.: in /etc/fstab). Otherwise, you will not be able to execute the CEF file, and you need to locate it in another directory.
Make sure there is a minimum of 1GB available free space on /tmp directory after you copied the CEF file.
By default, CEF files are extracted to /tmp directory. To change the destination directory, use the option --dest-dir <directory> when executing the CEF file.
Replace <CEF_FILE> placeholder and execute the following commands:
```
cd /tmp
chmod 755 <CEF_FILE>
./<CEF_FILE>
```

The Installation Process

The CEF installer displays a series of questions, requiring you to verify that your appliance meets the installation prerequisites:
Once you answered Yes to all questions, the installer will verify the system meets all prerequisites
Next, you can change the time and date settings (or leave them as they are)
Choose an environment name for this DPOD installation, each DPOD installation must have a unique 4-character environment name

If you are installing a second DPOD machine that will be used as the standby machine in a DR Active/Standby scenario, the environment name must be identical to the environment name of the active DPOD installation.
Choose whether you use SSD storage
Set Store Service dedicated user
(Optional) If you have 2 NIC than this question may appear :
Accept or Decline the EULA

Choose the installation architecture, Ensure your appliance has enough memory and storage available, or the installation will stop
The Architecture options you see on-screen may differ from the ones in the screenshot below, as they depend on the installation package you obtained.
The installation will commence. The process takes 5-15 minutes, and when it ends the installer displays a message indicating whether the process was successful or not,
alongside the name of the installation log file
Verify your installation
