Installing a Proof-of-Concept Cluster

In this procedure, Cloudera Manager automates the installation of the Oracle JDK, Cloudera Manager Server, embedded PostgreSQL database, Cloudera Manager Agent, CDH, and managed service software on cluster hosts. Cloudera Manager also configures databases for the Cloudera Manager Server and Hive Metastore and optionally for Cloudera Management Service roles.

Cluster Host Requirements:

The hosts you intend to use must satisfy the following requirements:

• You must be able to log in to the Cloudera Manager Server host using the root user account or an account that has passwordless sudo privileges.
• The Cloudera Manager Server host must have uniform SSH access on the same port to all hosts. For more information, see CDH and Cloudera Manager Networking and Security Requirements.
• All hosts must have access to standard package repositories for the operating system and either archive.cloudera.com or a local repository with the required installation files.
• SELinux must be disabled or set to permissive mode before running the installer. For more information, see Disable SELinux.
