Is it possible to change IP addresses of Tableau cluster without reinstalling?

Glauber Ribeiro Aug 12, 2016 12:04 PM

I manage a Tableau Server 9.2 HA cluster (management server + 2 workers, total 3 servers) which is being relocated, so all the servers are going to change IP addresses. The cluster is configured using server names (not IPs), and the IPs are defined in each server's host file (long sad story, lack of DNS support in production).

This can't be the first time this is being done! I would love to hear your experiences. Will I be able to change the IPs, edit the host files, and bring the cluster up without problem? Should I plan to reinstall and restore from backup? (Another option would be to make it into a single-server system, do the move, then re-establish the HA, but restoring from backup would probably take less time than that.)

Thanks,

glauber

If I were in this pickle, I would probably opt for a re-install. I forget where I see stuff at, but I know there is a trusted relationship between the primary and workers which is stored in memory at the IP address There may be a way to hack this via restarting the tabadmsvc via the services panel, but I forget the specifics.

In fact, I am in this pickle but not exactly. We are moving our cluster to a new windows domain and I will most likely end up having to do a re-install for this.

There are ways around, but then there is the "safe" option...

Well, the answer is, yes. As long as you use server names (and not ip addresses) throughout, it "just works". Some configuration items (tabadmin set) which include IP addresses (load balancer configuration, for example) can be safely redone after the IP change.

For the record, this was version 9.2.3.
