Instantiating a Cloudera Manager Image

Complete the following steps to create a new Cloudera Manager instance from a virtual machine image.

  1. Instantiate the Cloudera Manager image.
  2. If the Cloudera Manager database will be hosted on a remote host, also instantiate the database host image.
  3. Ensure that the cloudera-scm-server service is not running by running the following command on the Cloudera Manager host:
    service cloudera-scm-server status
    If it is running, stop it using the following command:
    service cloudera-scm-server stop
  4. On the Cloudera Manager host, create a file named uuid in the /etc/cloudera-scm-server directory. Add a globally unique identifier to this file using the following command:
    cat /proc/sys/kernel/random/uuid > /etc/cloudera-scm-server/uuid
    The existence of this file informs Cloudera Manager to reinitialize its own unique identifier when it starts.
  5. Run the following command to start the Cloudera Manager service:
    service cloudera-scm-server start
  6. Run the following command to enable automatic restart for the cloudera-scm-server:
    • SLES:
      chkconfig cloudera-scm-server on
    • RHEL 7.x /CentOS 7.x.x:
      systemctl enable cloudera-scm-server.service
    • Ubuntu:
      update-rc.d -f cloudera-scm-server defaults
