On a server host that has Internet access, use a command line editor to perform the following steps:

  1. Log in to your host as root.

  2. Download the Ambari repository file to a directory on your installation host.

    wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.1.0/ambari.repo -O /etc/yum.repos.d/ambari.repo


    Do not modify the ambari.repo file name. This file is expected to be available on the Ambari Server host during Agent registration.

  3. Confirm that the repository is configured by checking the repo list.

    yum repolist You should see values similar to the following for Ambari repositories in the list.

    Version values vary, depending on the installation.
