Form a cluster and install Vertica

Use the install_vertica script to combine two or more individual VMs to form a cluster and install the Vertica database.

Use the install_vertica script to combine two or more individual VMs to form a cluster and install the Vertica database.

Before you start

Before you run the install_vertica script:

  • Check the Virtual Network page for a list of current VMs and their associated private IP addresses.

  • Identify your storage location. The installer assumes that you have mounted your storage to /vertica/data. To specify another location, use the --data-dir argument.

  • Identify your storage location. To create your database's data directory on mounted RAID drive, when you run the install_vertica script, provide /vertica/data as the value of the --data-dir option .

Combine virtual machines (VMs)

The following example shows how to combine VMs using the install_vertica script.

  1. While connected to your primary node, construct the following command to combine your nodes into a cluster.

    $ sudo /opt/vertica/sbin/install_vertica --hosts 10.2.0.164,10.2.0.165,10.2.0.166 --dba-user-password-disabled --point-to-point --data-dir /vertica/data --ssh-identity ~/<name-of-private-key>.pem --license <license.file>

  2. Substitute the IP addresses for your VMs and include your root key file name, if applicable.

  3. Include the --point-to-point parameter to configure spread to use direct point-to-point communication between all Vertica nodes, as required for clusters on Azure when installing or updating Vertica.

  4. If you are using Vertica Community Edition, which limits you to three nodes, specify -L CE with no license file.

  5. After you combine your nodes, to reduce security risks, keep your key file in a secure place—separate from your cluster—and delete your on-cluster key with the shred command:

    $ shred examplekey.pem

  6. Reboot your cluster to complete the cluster formation and Vertica installation.
