RedHat Enterprise Linux

Tags: Flow on-prem

Flow Enterprise only supports RedHat Enterprise Linux (RHEL) 7 and above.  We require this to insure that customers have the latest OS compatibility and security updates. 

To prepare RHEL 7 for installation of Docker, Replicated, and Flow Enterprise, it is recommended that you follow the steps outlined in this document.

Install All Updates

Bring RHEL up to the latest set of updates before beginning.  This can be done with the command:

sudo yum update -y

After installing updates, reboot the system, as there may have been kernel-level updates installed.

Install Dependencies

For the installation script to go smoothly, install the following packages:

  • yum-utils
  • device-mapper-persistent-data
  • lvm2

This can be done by running this command:

sudo yum install -y \
   yum-utils \
   device-mapper-persistent-data \

Enable Extras Repository

For things to work smoothly, it is expected that you will also enable the "extras" repository for RHEL.  This can be done by executing the following command:

sudo yum-config-manager --enable rhel-7-server-extras-rpms

If you are in AWS, you will also need to execute:

sudo yum-config-manager --enable rhui-REGION-rhel-server-extras

Once you have enabled these repositories, you will need to update the yum cache appropriately:

sudo yum makecache fast

Remove Older Docker Installations

If you have previously installed docker on the server, it is recommended that you remove it.  This can be done by running the commands:

sudo yum remove \
   docker \
   docker-common \
   docker-selinux \
   docker-engine-selinux \
