Step 3: Install Cloudera Manager Server

Step 1: Configure a Repository Step 2: Install Java Step 3: Install Cloudera Manager Server Step 4: Install Databases Step 5: Set Up the Cloudera Manager Database Step 6: Install CDH and Other Software Step 7: Set Up a Cluster

In this step you install the Cloudera Manager Server packages on the Cloudera Manager host.

Install the Cloudera Manager Server Packages

  1. Install the Cloudera Manager Server packages either on the host where the database is installed, or on a host that has access to the database. This host need not be a host in the cluster that you want to manage with Cloudera Manager. On the Cloudera Manager Server host, type the following commands to install the Cloudera Manager packages.
    OS Command
    RHEL, if you have a yum repo configured 
    sudo yum install cloudera-manager-daemons cloudera-manager-server
    RHEL,if you're manually transferring RPMs 
    sudo yum --nogpgcheck localinstall cloudera-manager-daemons-*.rpm
sudo yum --nogpgcheck localinstall cloudera-manager-server-*.rpm
    SLES 
    sudo zypper install cloudera-manager-daemons cloudera-manager-server
    Ubuntu or Debian 
    sudo apt-get install cloudera-manager-daemons cloudera-manager-server
  2. If you are using an Oracle database for Cloudera Manager, increase the Java heap size 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 CM_JAVA_OPTS and change the -Xmx2G option to -Xmx4G.
  3. On all hosts, run the following command to install the Cloudera Manager agent:
    OS Command
    RHEL, CentOS, Oracle Linux 
    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
  4. On all hosts, 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.
    For more information on Agent configuration options, see Agent Configuration File.
  5. Start the Agents by running the following command on all hosts:
    RHEL 7, SLES 12, Debian 8, Ubuntu 16.04
    sudo systemctl start cloudera-scm-agent
    If the agent starts without errors, no response displays.
    RHEL 5 or 6, SLES 11, Debian 6 or 7, Ubuntu 12.04, 14.04
    sudo service cloudera-scm-agent start
    You should see the following: 
    Starting cloudera-scm-agent: [ OK ]

Install and Configure Databases

After installing the Cloudera Manager Server packages, continue to Step 4: Install and Configure Databases.
