database cannot replicated via Elixir 1.9.2 version

[Raymond0331]

Erlang/OTP 22 [erts-10.5.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1]

In this elixir version does not work.
Try to start two nodes in my macbook, by the following steps:
node1 : iex --sname node1@localhost -S mix
node2: iex --erl "-todo port 5555" --sname node2@localhost -S mix
in other terminal test add entries:
curl -d "" "http://localhost:5454/add_entry?list=bob&date=2018-12-19&title=Movies"
curl "http://localhost:5555/entries?list=bob&date=2018-12-19"
the curl command return empty, and the local folder in node2 is empty too.
