Cloudera Manager Installation and Setup

Install Cloudera Manager, install Cloudera Manager agents and daemons, add Cloudera Management service, enable TLS, and finally configure clusters to use Kerberos, if you are transitioning from Ambari 7.1.x.x to Cloudera Manager 7.3.1 using the AM2CM tool.

Prepare to install and configure the Cloudera Manager packages. For more information, see Configuring Repository. Do this if you have not done it already. Confirm that the repo is set up.
Install Cloudera Manager Server. For more information on installing Cloudera Manager Server, see Installing Cloudera Manager.

note
During the upgrade process, you can place Cloudera Manager and its related Cloudera Manager Services components on the same node as Ambari. Ensure that the node has sufficient capacity to temporarily run Cloudera Manager and Ambari in parallel. If you do not wish to colocate these services, you can place them on separate management nodes in the cluster.
Preconfigure the databases for:
- Cloudera Manager Server
- Cloudera Management Service roles - Reports Manager
- Data Analytics Studio (DAS) Supported with PostgreSQL only.
- Hue
- Each Hive metastore
- Oozie
- Data Analytics Studio
- Schema Registry
- Streams Messaging Manager
  For more information, see Setup Cloudera Manager database and Install and Configure Databases.
Start Cloudera Manager Server and Cloudera Manager agents on all hosts. For more information, see Cloudera Manager Agents .

Install Agents on all hosts in the cluster. It is possible to add hosts to Cloudera Manager using the Installation Wizard.

It is easier to install the Cloudera Manager agents (daemons and agent packages) on all cluster hosts:

Operating System	Command
RHEL	sudo yum install
	cloudera-manager-daemons
	cloudera-manager-agents
SLES	sudo zypper install
	cloudera-manager-daemons
	cloudera-manager-agents
Ubuntu	sudo apt-get install
	cloudera-manager-daemons
	cloudera-manager-agents

After the installation is complete, update the server_host=localhost line in the /etc/cloudera-scm-agent/config.ini the Cloudera Manager agent configuration file on each host to %server_host=<cloudera manager server>;.

Install Cloudera Manager User licence. For more information, see Installation Wizard. (Upload the license file and exit the cluster setup by clicking the Cloudera Manager icon )
caution
- Do not set up a cluster using the Wizard (Step 7) .
- Do not proceed to Welcome (Add Cluster - Installation).
Add Cloudera Manager management service to the cluster. To add services to the cluster, see Select Services.
Set up Kerberos. If you have a Kerberos cluster, then you must add the KDC details in the Administration>Security>Kerberos Credentials>Setup KDC for Cloudera Manager page using Cloudera Manager. For more information on Kerberos and Active Directory, see Enabling Kerberos authentication for CDP
note
- You must set the value of Maximum Renewable Life for Principals to 0 or to the value that was provided for Ambari KDC. If Maximum Renewable Life for Principal and Ambari KDC do not match, keytabs generation fails in Cloudera Manager.
- If you are not upgrading from CDH or HDP to CDP Private Cloud Base, you can follow the Production Installation instructions to perform a fresh installation in your production environment.
