raoyitao opened a new issue #2054: [CouchDB 2.3.1] Cluster setup timed out waiting for nodes to connect
URL: https://github.com/apache/couchdb/issues/2054
 
 
   I have 3 hosts, on each there is a CouchDB 2.3.1 running, but I cannot join them as a cluster, I got the error "Cluster setup timed out waiting for nodes to connect", I search through Google but there's not hint why this happen.
   
   ## Description
   
   I have configure **vm.args**, adding following content:
   
   **-name couchdb@<[abc].mydoman.com>
   -setcookie brum_brum
   -kernel inet_dist_listen_min 9100
   -kernel inet_dist_listen_max 9110**
   
   The 3 hosts are **a.mydomain.com**, **b.mydomain.com**, **c.mydomain.com**, they can ping each other smoothly. In local.ini config files, the same **port**, **uuid** and **admin/password** were set.
   
   Then I can run CouchDB on these hosts:
   > **COUCHDB_ARGS_FILE=/path/to/my/vm.args ./bin/couchdb**
   
   I also run this command on another host to test connections:
   
   > **erl -name couchdb@d.mydomain.com -setcookie 'brum_brum' -kernel inet_dist_listen_min 9100 -kernel inet_dist_listen_max 9110**
   (couchdb@d.mydomain.com)> **net_kernel:connect_node('couchdb@a.mydomain.com').**
   **true**
   
   It shows all these nodes can be connected.
   
   ## Steps to Reproduce
   
   I follow the official document to setup a cluster, with the command for each node:
   **curl -X POST -H "Content-Type: application/json" http://admin:pass@<IP-ADDR>:<PORT>/_cluster_setup -d '{"action": "enable_cluster", "bind_address": "0.0.0.0", "username": "admin", "password": "pass", "node_count": "3"}'**
   
   Then choose a coordination node and run these commands for the other two:
   **curl -X POST -H "Content-Type: application/json" http://admin:pass@<COORD-IP>:<PORT>/_cluster_setup -d '{"action": "enable_cluster", "bind_address": "0.0.0.0", "username": "admin", "password": "pass", "port": <PORT>, "node_count": "3", "remote_node": "<REMOTE-IP>", "remote_current_user": "admin", "remote_current_password": "pass"}'**
   **curl -X POST -H "Content-Type: application/json" http://admin:pass@<COORD-IP>:<PORT>/_cluster_setup -d '{"action": "add_node", "host": "<REMOTE-IP>", "port": <PORT>, "username": "admin", "password": "pass"}'**
   
   At last finishe cluster setup:
   **curl -X POST -H "Content-Type: application/json" http://admin:pass@<COORD-IP>:<PORT>/_cluster_setup -d '{"action": "finish_cluster"}'**
   
   But unfortunately I got the error after a few seconds:
   **{"error":"setup_error","reason":"Cluster setup timed out waiting for nodes to connect"}**
   
   The status of CouchDB cluster:
   > **curl http://admin:pass@<COORD-IP>:<PORT>/_cluster_setup**
   **{"state":"cluster_enabled"}**
   
   ## My Environment
   
   * CouchDB Version used: **2.3.1 extracted from el7 RPM package**
   * Operating System and version: **Red Hat Enterprise Linux Server release 6.10**
   
   ## Additional context
   
   I have ever set 3 CouchDB servers as a cluster, but the version I used is 2.3.0. And now I switch to 2.3.1 seems I cannot setup cluster. I don't know why there is a timeout message.
