Manually Install Cloudera Software Packages
This topic shows how to manually install Cloudera software packages, namely Cloudera Manager and CDH. This is useful for environments where it is not possible to use Cloudera Manager to install the required packages, such as organizations where password-less sudo is not permitted.
Although you can install the software packages manually, Cloudera does not support clusters that are not deployed and managed by Cloudera Manager.
Install Cloudera Manager Packages
- On the Cloudera Manager Server host, type the following commands to install the Cloudera Manager packages.
OS Command RHEL, CentOS, Oracle Linux
sudo yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server
sudo zypper install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server
sudo apt-get install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server
- If you are using an Oracle database for Cloudera Manager Server, edit the /etc/default/cloudera-scm-server file on the Cloudera Manager server host. Locate the line that begins with export CMF_JAVA_OPTS and change the -Xmx2G option to -Xmx4G.
Manually Install Cloudera Manager Agent Packages
The Cloudera Manager Agent is responsible for starting and stopping processes, unpacking configurations, triggering installations, and monitoring all hosts in a cluster. You can install the Cloudera Manager agent manually on all hosts, or Cloudera Manager can install the Agents in a later step. To use Cloudera Manager to install the agents, skip this section.
- Use one of the following commands to install the Cloudera Manager Agent packages:
OS Command RHEL, if you have a yum repo configured:
$ sudo yum install cloudera-manager-agent cloudera-manager-daemons
RHEL, if you're manually transferring RPMs:
$ sudo yum --nogpgcheck localinstall cloudera-manager-agent-package.*.x86_64.rpm cloudera-manager-daemons
$ sudo zypper install cloudera-manager-agent cloudera-manager-daemons
Ubuntu or Debian
$ sudo apt-get install cloudera-manager-agent cloudera-manager-daemons
- On every cluster host, configure the Cloudera Manager Agent to point to the Cloudera Manager Server by setting the following properties in the /etc/cloudera-scm-agent/config.ini configuration file:
Property Description server_host Name of the host where Cloudera Manager Server is running. server_port Port on the host where Cloudera Manager Server is running.
- Start the Agents by running the following command on all hosts:
- RHEL 7, SLES 12, Debian 8, Ubuntu 16.04 and higher
sudo systemctl start cloudera-scm-agentIf the agent starts without errors, no response displays.
- RHEL 5 or 6, SLES 11, Debian 6 or 7, Ubuntu 12.04 or 14.04
sudo service cloudera-scm-agent startYou should see the following:
Starting cloudera-scm-agent: [ OK ]
When the Agent starts, it contacts the Cloudera Manager Server. If communication fails between a Cloudera Manager Agent and Cloudera Manager Server, see Troubleshooting Installation Problems. When the Agent hosts reboot, cloudera-scm-agent starts automatically.
