How do I upgrade to a new version of quasardb?

If upgrading to a new patch version (e.g. 1.1.0 to 1.1.1):

For each node in the cluster:

  1. Shut down the qdb_httpd web server on the node, if applicable.
  2. Shut down the qdbd daemon on the node.
  3. Read the qdbd daemon log file to verify the daemon closed properly and no error occurred.
  4. Verify the operating system shows the qdbd daemon is no longer running.
  5. Uninstall the old version of quasardb.
  6. Install the new version of quasardb.
  7. Copy the new license file and configuration file to the new installation location, if applicable.
  8. Start the qdbd daemon on the node.
  9. Start the qdb_httpd web server on the node, if applicable.
  10. Verify the operating system shows the qdbd daemon is running.
  11. Read the qdbd daemon log file to verify the daemon started properly and has stabilized.
  12. The node upgrade is complete!

Once all nodes are upgraded:

  1. Test your ring with quasardb shell to verify it is responding to requests properly.
