Instructions

Step 1: Use a workstation with access to the Internet and download the tarball image of the appropriate Hortonworks yum repository.

Table 1.3. Deploying HDP - Option I
Cluster OS	HDP Repository Tarballs
RHEL/ CentOS 5.x	//public-repo-1.hortonworks.com/HDP-1.1.1.16/repos/centos5/HDP-1.1.1.16-centos5.tar.gz //public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.15/repos/centos5/HDP-UTILS-1.1.0.15-centos5.tar.gz
RHEL/ CentOS 6.x	//public-repo-1.hortonworks.com/HDP-1.1.1.16/repos/centos6/HDP-1.1.1.16-centos6.tar.gz //public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.15/repos/centos6/HDP-UTILS-1.1.0.15-centos6.tar.gz
SLES 11	//public-repo-1.hortonworks.com/HDP-1.1.1.16/repos/suse11/HDP-1.1.1.16-suse11.tar.gz //public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.15/repos/suse11/HDP-UTILS-1.1.0.15-suse11.tar.gz

	Note
	The EPEL repository is not available as a tarball currently. Use one of Options II through IV to provide access to the EPEL repository.

Step 2: Create an HTTP server.

On the mirror server, install an HTTP server (such as Apache httpd) using the instructions provided here.
Activate this web server.
Ensure that the firewall settings (if any) allow inbound HTTP access from your cluster nodes to your mirror server.
Note
If you are using EC2, make sure that SELinux is disabled.

Step 3: On your mirror server, create a directory for your web server.

For example, from a shell window, type: mkdir –p /var/www/html/hdp/
If you are using a symlink, enable the followsymlinks on your web server.

Step 4: Copy the HDP Repository Tarball to the directory created in step 3, and untar it.

Step 5: Verify the configuration.

The configuration is successful, if you can access the above directory through your web browser. To test this out, browse to the following location: http://yourwebserver/hdp/HDP-1.1.1.16/
You should see directory listing for all the HDP components along with the RPMs at the following location: HDP-1.1.1.16/repos/os.

Step 6: Configure the yum or zypper clients on all the nodes in your cluster.

For RHEL and CentOS:
1. Fetch the yum configuration file from your mirror server.
```
http://yourwebserver>/hdp/HDP-1.1.1.16/repos/os/hdp.repo 
```
  where os is either centos5 or centos6.
2. Store the hdp.repo file in a temporary location and edit it, changing the value of the baseurl property to the local mirror URL. For example, http://yourwebserver/hdp/HDP-1.1.1.16/repos/os
3. Use scp or pdsh to copy the client yum configuration file to /etc/yum.repos.d/ directory on every node in the cluster.
For SLES:
1. Fetch the yum configuration file from your mirror server.
```
http://yourwebserver>/hdp/HDP-1.1.1.16/repos/suse11/hdp.repo 
```
2. Store the hdp.repo file in a temporary location and edit it, changing the value of the baseurl property to the local mirror URL. For example, http://yourwebserver/hdp/HDP-1.1.1.16/repos/suse11.
3. Store the hdp.repo file back into the repository location in the web server.
```
cp /tmp/hdp.repo /var/www/html/hdp/HDP-1.1.1.16/suse11/ 
```
4. On every node, invoke the following command:
```
zypper addrepo -r http://yourwebserver/hdp/HDP-1.1.1.16/repos/suse11/hdp.repo
```

Step 7 [Conditional]: If your cluster runs CentOS or RHEL, and if you have multiple repositories configured in your environment, deploy the following plugin on all the nodes in your cluster.

Install the plugin.
- For RHEL and CentOs v5.x
```
yum install yum-priorities
```
- For RHEL and CentOs v6.x
```
yum install yum-plugin-priorities
```
Edit the /etc/yum/pluginconf.d/priorities.conf file to add the following:
```
[main]
enabled=1
gpgcheck=0
```
