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
$ 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
Name of the host where Cloudera Manager Server is running.
Port on the host where Cloudera Manager Server is running.
- Start the Agents by running the following command on all
sudo systemctl start cloudera-scm-agent
If the agent starts without errors, no response displays.
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,
