MapR Installer

The MapR Installer makes the installation of a MapR cluster easy. After taking you through the process of selecting services and configuring the cluster, the installer installs MapR software

You can use the MapR Installer to install MapR 4.1, 5.0, 5.1, 5.2, and maintenance releases such as 5.2.1. You can also use the MapR Installer to perform upgrades on clusters that have a MapR Installer database. To see the MapR Installer in action, watch this video.

Setting Up and Running the MapR Installer

To set up and run the installer, complete the following steps:
  1. Select a node to run the MapR Installer. The node from which you run the MapR Installer must also be one of the nodes you plan to install the cluster on. Before you begin, you may want to check the prerequisites and known issues.
  2. Download the mapr-setup.sh script. Choose one of the following options:
    • Download the setup script directly from package.mapr.com to the node that will run the MapR Installer:
      $ wget http://package.mapr.com/releases/installer/mapr-setup.sh -P /tmp
    • Download to your local workstation, and copy to the node that will run the MapR Installer:
      1. On the MapR Download Page, click Download, and save the setup script to a location on your workstation.
      2. Use a tool such as SCP to copy the file to the node that will run the MapR Installer:
        $ scp mapr-setup.sh user@server /tmp
  3. Change the file permissions so that you can run the file.
    $ chmod +x /tmp/mapr-setup.sh
  4. Run the mapr-setup.sh script to configure the node to run the MapR Installer. Run the following command as the root user from the directory that contains the script. The script prompts you for some information. If you have not used this script before, consider reviewing How the MapR Installer Works to be prepared.
    $ sudo bash /tmp/mapr-setup.sh
    Note: For examples of options you can use with mapr-setup.sh, see How the MapR Installer Works.
  5. Start the MapR Installer. Open the MapR Installer URL:
    https://<Installer Node hostname/IPaddress>:9443

    You will be prompted to log in as the MapR Administrator user that you configured while running the mapr-setup.sh script.

Other Tasks You Can Perform with the MapR Installer

Once the initial installation completes, you can use the same MapR Installer URL to upgrade the cluster, apply a patch, or add nodes and additional services:
Use this option . . . To
Incremental Install Add nodes, add services, and upgrade services that are already installed on the cluster.
Maintenance Update Update your cluster to a new patch version of MapR Core or apply a patch.
Version Upgrade Upgrade the cluster to a newer MapR version, apply a patch, and upgrade services that are already installed on the cluster.
Uninstall Remove MapR software.
Note: The MapR Installer definitions are updated frequently. Update the MapR Installer to get the latest ecosystem components and MapR versions.
