When I execute etcdctl cluster-health, it always fail with below error.

# etcdctl cluster-health
cluster may be unhealthy: failed to list members
Error:  client: etcd cluster is unavailable or misconfigured; error #0: dial tcp 192.168.2.4:2379: getsockopt: connection refused

Resolution

You need to specify --peers or (-C) and certs. Please use following command.

  # export `cat /etc/etcd/etcd.conf |grep ETCD_LISTEN_CLIENT_URLS`
  # etcdctl -C ${ETCD_LISTEN_CLIENT_URLS} --ca-file=/etc/etcd/ca.crt \
    --cert-file=/etc/etcd/peer.crt     \
    --key-file=/etc/etcd/peer.key cluster-health
