Introduction to Cloudera Manager Installation

Cloudera Manager automates the installation and configuration of CDH and managed services on a cluster, requiring only that you have root SSH access to your cluster's hosts, and access to the internet or a local repository with installation files for all these hosts. Cloudera Manager installation software consists of:
  • A small self-executing Cloudera Manager installation program to install the Cloudera Manager Server and other packages in preparation for host installation.
  • Cloudera Manager wizard for automating CDH and managed service installation and configuration on the cluster hosts. Cloudera Manager provides two methods for installing CDH and managed services: traditional packages (RPMs or Debian packages) or parcels. Parcels simplify the installation process, and more importantly allows you to download, distribute, and activate new minor versions of CDH and managed services from within Cloudera Manager.

About the Cloudera Manager Installation Program

The Cloudera Manager installation program, which you install on the host where you want the Cloudera Manager Server to run:

  • Installs the package repositories for Cloudera Manager and the Oracle Java Development Kit (JDK) 1.7
  • Installs the Cloudera Manager Server
  • Installs and configures an embedded PostgreSQL database for use by the Cloudera Manager Server and some Cloudera Management Service roles, Hive Metastore, and Cloudera Navigator Audit Server

Installing Cloudera Manager for the First Time

To install Cloudera Manager, you:
  • Optionally install a database application on the Cloudera Manager Server host or on a host that the Cloudera Manager Server can access, and (depending on the configuration you decide on) on other hosts as well.
  • Run the Cloudera Manager installer on one host.
  • Install CDH, managed services, and Cloudera Manager Agents on the other hosts.
The following illustrates a sample installation:

About the Cloudera Manager "First Run" Wizard

After you install Cloudera Manager and you connect to the Cloudera Manager Admin Console for the first time, you use the Cloudera Manager "first run" wizard to do the following:
  • Discover cluster hosts
  • Optionally install the Oracle JDK
  • Optionally install CDH, managed service, and Cloudera Manager Agent software on the hosts
  • Select which services to run
  • Specify the mapping of service roles to hosts
  • Confirm service configurations and start the services
You can choose to abort the software installation process and the Cloudera Manager wizard automatically reverts and completely rolls back the installation process for any uninstalled components. (Installation that has completed successfully on a given host is not rolled back on that host.)

Installation Phases and Paths for Cloudera Manager, CDH, and Managed Services

The following diagram illustrates the phases required to install Cloudera Manager, CDH, and managed services. Every phase is required, but there are multiple ways to accomplish each phase, depending on your organization's policies and requirements.

The six phases are grouped into three installation paths based on how the Cloudera Manager Server and database software is installed on the Cloudera Manager Server and cluster hosts. For each path you can choose to use the embedded PostgreSQL database or an external database. To review the criteria for choosing a path, see Installing Cloudera Manager, CDH, and Managed Services.
