Installing Vertica with the Installation Script
Run the installation script after you have installed the Vertica package. The installation script runs on a single node, using a Bash shell, and 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 the 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 takes the following basic parameters:
- A list of hosts on which to install.
- Optionally, the Vertica RPM/DEB path and package file name if you have not pre-installed the server package on other potential hosts in the cluster.
- Optionally, a system user name. If you do not provide a user name, then the installation script creates a new system user named
dbadmin. If you do provide a username and the username does not exist on the system, then the installation script creates that user.
# /opt/vertica/sbin/install_vertica --hosts node0001,node0002,node0003 \ --rpm /tmp/vertica-9.1.1-0.x86_64.RHEL6.rpm \ --dba-user mydba
The installation script sets up passwordless ssh for the administrator user across all the hosts. If passwordless ssh is already set up, the installation script verifies that it is functioning correctly.
