3. Configure the Remote Repository

The standard HDP install fetches the software from a remote yum repository over the Internet. To use this option, you must set up access to the remote repository and have an available Internet connection for each of your hosts.

	Note
	If your cluster does not have access to the Internet, or you are creating a large cluster and you want to conserve bandwidth, you can instead provide a local copy of the HDP repository that your hosts can access. For more information, see Deployment Strategies for Data Centers with Firewalls., a separate document in this set.

For each node in your cluster, download the repo configuration file hdp.repo and ambari.repo. From a terminal window, type:

For RHEL and CentOS 5

wget -nv //public-repo-1.hortonworks.com/HDP/centos5/1.x/updates/1.2.1/hdp.repo  -O /etc/yum.repos.d/hdp.repo
 wget -nv //public-repo-1.hortonworks.com/ambari/centos5/1.x/updates/1.2.2.4/ambari.repo -O /etc/yum.repos.d/ambari.repo

For RHEL and CentOS 6

wget -nv //public-repo-1.hortonworks.com/HDP/centos6/1.x/updates/1.2.1/hdp.repo -O /etc/yum.repos.d/hdp.repo
 wget -nv //public-repo-1.hortonworks.com/ambari/centos5/1.x/updates/1.2.2.4/ambari.repo -O /etc/yum.repos.d/ambari.repo

For SLES

wget -nv //public-repo-1.hortonworks.com/HDP/centos5/1.x/updates/1.2.1/hdp.repo -O /etc/zypp/repos.d/hdp.repo
 wget http://public-repo-1.hortonworks.com/ambari/centos5/1.x/updates/1.2.2.4/ambari.repo -O /etc/zypp/repos.d/ambari.repo

Confirm the HDP repository is configured by checking the repo list.
- For RHEL/CentOS
```
yum repolist
```
- For SLES
```
zypper repos 
```

You should see something like this. Ensure you have HDP-1.2.1, HDP-UTILS-1.1.0.15, and AMBARI-1.2.2.4:
