In your original command, you listed the same port twice. That may have
been at least part of the difficulty.
It's probably fine to just use one zk node - as the zookeeper instances
should be aware of each other.
I also assume that if your solr.in.sh (or windows equavalent) has the
properly form
I issue '-z localhost:2181 -z localhost:2182 -z localhost:2183' for each
node's start command and later when I create collection, all 3 zk nodes has
registered my configset.
Never try but I think maybe only use -z localhost:2181, then all 3 nodes in zk
ensemble will synchronize themselves.
