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

• Red Hat Enterprise Linux Server release 7.47-7.89
• CentOS version 7.47-7.89

Prerequisites

• Make sure to follow Prepare Pre-Installed Operating System.

Execute the CEF

...

Download the CEF (Compressed Executable Format) file and copy it to /tmp directory.

...

File

• The CEF file may be executed from any directory that meets the following requirements (e.g. /tmp):
  • The directory has at least 1GB of free space after the CEF file is copied.
  • The directory 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
  • The directory is NOT one of the following: /app, /logs, /data, /shared, /installs.

• Download the CEF (Compressed Executable Format) file and copy it to the chosen directory.

• By default, CEF files are file content is extracted to /tmp directory directory. To change the destination directory, use the option --dest-dir <directory> when executing the CEF file.

• Replace <CEF_FILE> placeholder and execute Execute the following commands:

  Code Block
  language bash theme RDark
  cd /tmp<CEF_DIRECTORY> chmod 755 <CEF_FILE> ./<CEF_FILE>

  
  

The Installation Process

1. The CEF installer displays a series of questions, requiring you to verify that your appliance meets machine and operating system meet the installation prerequisites:.Image Removed
   
2. Once you answered answer Yes to all questions, the installer will verify the system meets all prerequisites.
   Critical compatibility checks must be satisfied in order to install the system, while other informational compatibility checks will make sure the operating system is optimized and will notify if changes are recommended to be made.
   Please take time to review the results of these checks after installation, and perform all applicable optimizations. The compatibility checks report can be found in /installs/logs/appliance_checks-<date time>.log.

3. Next, you can change the time and date settings

   (or leave them as they are)

4. Choose an environment name for this DPOD installation, each DPOD installation must have a unique 4-character environment name.

   Info
   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. If you are installing DPOD as part of a Cell environment, the environment name must be identical between the Cell Manager and all Cell Members.

   Please review the script before executing it and make sure the OS parameters values match your organization's policy.

   Code Block
   language bash theme RDark
   /app/scripts/tune-os-parameters.sh
