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.
- 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.
Preconfigure the databases for:
- Cloudera Manager Server
- Cloudera Management Service roles - Reports Manager
- Data Analytics Studio (DAS) Supported with PostgreSQL only.
- Each Hive metastore
- Data Analytics Studio
- Schema Registry
- Streams Messaging Manager
- 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 )
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
- The AM2CM tool migrates service principal names from the service user names in the HDP cluster. If the HDP cluster has default service usernames then Cloudera Manager is configured with default principal names. For example hdfs, yarn, and hive. If the HDP cluster contains user names like cstm-hdfs and cstm-hive then Cloudera Manager is configured the principal names with same names. For more information, see Hadoop Users (user:group) and Kerberos Principals.
