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

Steps

Before installing Ambari, you must update username and password in the ambari.repo file. Run the following command:   vi /etc/yum.repos.d/ambari.repo

For example, the output displays the following:

#VERSION_NUMBER=2.7.5.0-72
[ambari-2.7.5.0]
#json.url = http://public-repo-1.hortonworks.com/HDP/hdp_urlinfo.json
name=ambari Version - ambari-2.7.5.0
baseurl=https://username:password@archive.cloudera.com/p/ambari/centos7/2.x/updates/2.7.5.0
gpgcheck=1
gpgkey=https://username:password@archive.cloudera.com/p/ambari/centos7/2.x/updates/2.7.5.0/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1

Next, 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.
