Get the Ambari Repository

Fetch the new Ambari repo and replace the old repository file with the new repository file on all hosts in your cluster.

	Important
	Check your current directory before you download the new repository file to make sure that there are no previous versions of the `ambari.repo` file. If you do not, and a previous version exists, the new download will be saved with a numeric extension, such as `ambari.repo.1`. Make sure that the version you copy is the new version.

Select the repository appropriate for your environment:

For RHEL/CENTOS/Oracle Linux 7 running on IBM Power Systems:

wget -nv http://public-repo-1.hortonworks.com/ambari/centos7-ppc/2.x/updates/2.6.2.0/ambari.repo -O /etc/yum.repos.d/ambari.repo

	Note
	If your cluster does not have access to the Internet, set up a local repository with this data before you continue.

	Note
	Ambari Server does not automatically turn off `iptables`. Check that your installation setup does not depend on `iptables` being disabled. After upgrading the server, you must either disable `iptables` manually or make sure that you have appropriate ports available on all cluster hosts.
