How to config etcd cluster about python-etcd HOT 6 CLOSED

the arguments you have shown above for monitorserver1 contain an error, namely the node name is spelt wrong in the -initial-cluster. monitorserve2= should be monitorserver2=

be aware that, as per the documentation: "The command line parameters starting with -initial-cluster will be ignored on subsequent runs of etcd"

be sure the cluster is clean by removing the data dir before running with new parameters, once this is done, run 'etcdctl member list' and you should see 2 entries with the corresponding IP addresses - not localhost.

Also be sure that the the IP's can reach each other on the required ports (no firewalls, etc..)

from python-etcd.

Hi.
I tried to modify monitorserve2 to monitorserver2, but it still not work.
etcdctrl member list still shows localhost ips:
[idcuser@docker-itm-agent-dal01 etcd-v2.0.9-linux-amd64]$ ./etcdctl member list
145f81b1e050b7c7: name=monitorserver2 peerURLs=http://127.0.0.1:2380 clientURLs=http://localhost:2379,http://localhost:4001
3260c3386e0bf9d8: name=monitorserver1 peerURLs=http://127.0.0.1:7001 clientURLs=http://localhost:2379,http://localhost:4001

I could ping each other successfully on each machine
And the port is working on each machine.

You need to remove the data dir in order to create a new cluster.
