Step 4: Deploy Cloudera Manager Server and Cloudera Manager Agents

Cloudera Manager packages are installed on the Cloudera Manager Server host (for the server packages) and on all the cluster nodes (the agent packages for the rest of the cluster).

On the Cloudera Manager Server host, type the following commands to install the Cloudera Manager packages:

OS Command

OS	Command
RHEL	`sudo yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server`
SLES	`sudo zypper install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server`
Ubuntu	`sudo apt-get install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server`

RHEL

sudo yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server

SLES

sudo zypper install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server

Ubuntu

sudo apt-get install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server

On all the cluster nodes (apart from the server which you already installed in Step 1), run the following command to install the Cloudera Manager agent packages:

OS Command

OS	Command
RHEL	`sudo yum install cloudera-manager-daemons cloudera-manager-agent`
SLES	`sudo zypper install cloudera-manager-daemons cloudera-manager-agent`
Ubuntu	`sudo apt-get install cloudera-manager-daemons cloudera-manager-agent`

RHEL

sudo yum install cloudera-manager-daemons cloudera-manager-agent

SLES

sudo zypper install cloudera-manager-daemons cloudera-manager-agent

Ubuntu

sudo apt-get install cloudera-manager-daemons cloudera-manager-agent

tip

You can execute this command using either ansible-playbook by running yml script from an ansible server that has access with sudo permissions to all the cluster nodes.

Alternatively, you can install (using sudo) the EPEL clustershell package on a node that has access and permission to run sudo on all the cluster nodes (preferably the server node).

The EPEL clustershell package is available on RHEL/SLES/Ubuntu, run the following command to install the EPEL clustershell package:

RHEL

sudo yum install clustershell python3-clustershell

SLES

sudo zypper install clustershell python3-clustershell

Ubuntu

sudo apt-get install clustershell python3-clustershell

Then, for example, if the customer grants you a local user called CDP with local sudo permission to root, then create your own customization file called /etc/clustershell/groups and change its ownership to CDP user (for easy updates in future). Then, add to it a line to represent all the cluster nodes. See the following example for a cluster with 10 nodes:

###
all: server[1-10].example.com
###

Note that in the same manner, you can set any alias for a subset of the cluster nodes (Nifi/Ozone etc.) and run a command only on that subset of nodes.

Now, you can run the following command from that node:

# clush -Bg all “sudo yum install cloudera-manager-daemons cloudera-manager-agent -y”

This command will run on all the servers in “all” in parallel and will install the packages, and once done, the output of all the executions is shown on the CLI.

Note that the command includes the “-y” option as the yum command should be executed here without user interaction.

If you are installing on Ubuntu, and are planning to add the Kudu service to the cluster and are planning to enable Apache Ranger, run the following command on all cluster hosts:
```
sudo apt-get install gettext-base
```
note
If you know in advance which hosts will be running the Kudu service roles, you only need to run this command on those hosts.
