My son was asking me to help him set up a server so that he can play with his friends – and i found this , easy to do.

I turns out that this version does not work well with latest minecraft , i download the version from Minecraft official website, it works pretty well

After you download the server, just run this command:

LD_LIBRARY_PATH=. ./bedrock_server
