Installing Vertica with the Installation Script

Run the installation script after you install the Vertica package. The installation script runs on a single node, using a Bash shell. It copies the Vertica package to all other hosts (identified by the --hosts argument) in your planned cluster.

The installation script runs several tests on each of the target hosts to verify that the hosts meet system and performance requirements for a Vertica node. The installation script modifies some operating system configuration settings to meet these requirements. Other settings cannot be modified by the installation script and must be manually reconfigured.

The installation script sets up passwordless ssh for the admin user across all hosts. If passwordless ssh is already set up, the installation script verifies that it functions correctly.
