I'd like to setup a cluster with CouchDB 2.0.0, but first I need a single host running well. I have tried MANY hostname configurations but they always result in: 

** System NOT running to use fully qualified hostnames **

This is what I have tried, a full re-installation and reboot after each try.

-sname couchdb@thiscomputer.local
-sname couchdb@thiscomputer
-sname couchdb@192.168.178.59
-sname thiscomputer

-name couchdb@thiscomputer.local
-name couchdb@thiscomputer
-name couchdb@192.168.178.59
-name thiscomputer

These all fail. So maybe I did something wrong in the server configuration?

hostname

pi@thiscomputer:~ $ sudo cat /etc/hostname 
thiscomputer

hosts

pi@thiscomputer:~ $ sudo cat /etc/hosts
127.0.0.1   thiscomputer    thiscomputer.local
::1         localhost ip6-localhost ip6-loopback
ff02::1     ip6-allnodes
ff02::2     ip6-allrouters

127.0.1.1   localhost

Support on GitHub here: https://github.com/apache/couchdb/issues/729#issuecomment-319202529 helped me solve the issue.

Lessons learned:

  • Never use -sname. We will be removing this suggestion from the sample vm.args file.
  • If this is a single node, not a cluster, always use -name couchdb@127.0.0.1.
  • If DNS isn't configured, use IP addresses only: -name couchdb@192.168.0.1.
  • If DNS is configured, use the FQDN only: -name couchdb@my.host.name.com
  • Tricks with /etc/hosts don't work as Erlang bypasses libresolv.
