3.2.1. Prerequisites

To configure local repositories for HDP deployment, your system must meet the following minimum requirements:

Your mirror server host must run on one of the following operating systems:
- 64-bit Red Hat Enterprise Linux (RHEL) v5.x, v6.x
- 64-bit CentOS v5.x, v6.x
- 64-bit SUSE Linux Enterprise Server (SLES) 11 SP1
- 64-bit Oracle Linux v5.x, v6.x
Ensure that this server and the cluster nodes are all running the same OS.
Note
Repository mirroring for heterogeneous clusters requires a more complex procedure than the one documented here.
The mirror server host must have several GB of storage available.
The firewall lets all cluster nodes (the servers where you want to install HDP) access this server.
Ensure that the mirror server has yum installed.
Add the yum-utils and createrepo packages on the mirror server.
```
yum install yum-utils createrepo
```

	Note
Repository mirroring for heterogeneous clusters requires a more complex procedure than the one documented here.

If your mirror host uses SLES, execute the following command to install the required packages:

zypper -n --no-gpg-checks install apache2 apache2-prefork apache2-utils python-curl python-gobject2 python-gpgme python-urlgrabber python-iniparse wget curl yum-metadata-parser yum yum-updatesd yum-utils createrepo
