Answer 1

Quoting José Valim :

This is likely happening because hostname -f is not returning a value, i.e. your machine doesn't know how it should be named in the network. You can use --sname, give the fullname, like --name foo@IP_ADDRESS or something that makes sense between machines (so they can find each other).

另一个解决方案是 set the hostname directly ( sudo hostname <FQDN> )，或更新主机文件(例如，Linux 中的 /etc/hosts)。
