RHEL/CentOS/Oracle Linux 6

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

Steps

Log in to your host as root.
Download the Ambari repository file to a directory on your installation host.
```
wget -nv https://archive.cloudera.com/p/ambari/2.x/2.5.0.3/centos6/ambari.repo -O /etc/yum.repos.d/ambari.repo
```
Important
Do not modify the ambari.repo file name. This file is expected to be available on the Ambari Server host during Agent registration.

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

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.

repo id              repo name                               status
ambari-2.5.0.0-1094  ambari Version - ambari-2.5.0.0-1094    12
base                 CentOS-6 - Base                         6,696
extras               CentOS-6 - Extras                       64
updates              CentOS-6 - Updates                      974
 repolist: 7,746

Version values vary, depending on the installation.

Install the Ambari bits. This also installs the default PostgreSQL Ambari database.
```
yum install ambari-server
```

Enter y when prompted to confirm transaction and dependency checks.

A successful installation displays output similar to the following:

	Note
When deploying a cluster having limited or no Internet access, you should provide access to the bits using an alternative method. Ambari Server by default uses an embedded PostgreSQL database. When you install the Ambari Server, the PostgreSQL packages and dependencies must be available for install. These packages are typically available as part of your Operating System repositories. Please confirm you have the appropriate repositories available for the postgresql-server packages.
