Connecting from a non-cluster host

You can use the Vertica vsql executable image on a non-cluster Linux host to connect to a Vertica database.

  • On Red Hat, CentOS, and SUSE systems, you can install the client driver RPM, which includes the vsql executable. See Installing the vsql client for details.

  • If the non-cluster host is running the same version of Linux as the cluster, copy the image file to the remote system. For example:

    $ scp host01:/opt/vertica/bin/vsql .$ ./vsql
  • If the non-cluster host is running a different distribution or version of Linux than your cluster hosts, you must install the Vertica server RPM in order to get vsql:

    1. Download the appropriate RPM package by browsing to Vertica website. On the Support tab, select Customer Downloads.

    2. If the system you used to download the RPM is not the non-cluster host, transfer the file to the non-cluster host.

    3. Log into the non-cluster host as root and install the RPM package using the command:

      # rpm -Uvh filename

      Where filename is the package you downloaded. Note that you do not have to run the install_vertica script on the non-cluster host to use vsql.


  • Use the same Command-line options that you would on a cluster host.

  • You cannot run vsql on a Cygwin bash shell (Windows). Use ssh to connect to a cluster host, then run vsql.
