How to change the IP and port of etcd listening

Question

my vm(virtual machine) have Multiple virtual network cards，so it has multiple ip，When I installed kubernetes, etcd was automatically installed and configured,and it automatically selected a default IP. but This IP is not what I want it to listen for. where and how can I configure the etcd to listen the right ip I wanted?

I installed kubernetes and the first control panel(master01) is work(ready). but when i join the second control panel(master02),I get the error like this: "error execution phase check-etcd: error syncing endpoints with etc: dial tcp 10.0.2.15:2379: connect: connection refused". so I checked etcd process found that one of it configuration is"--advertise-client-urls=10.0.2.15:2379",the ip is not what I want it to listen for. my realy ip is 192.168.56.101. And I want it listen for this ip. what should I do?

my kubernetes cluster version is v1.14.1

I hope the etcd can listen for the correct IP. And the second kubernetes master node can join the cluster successfully.

How are you installing Kubernetes and where are you installing it to? — Andy Shinn

Judging by the error message it looks like you're using kubeadm. You need to add extraArgs to your etcd in ClusterConfiguration, something like (untested):

apiVersion: kubeadm.k8s.io/v1beta1
kind: ClusterConfiguration
etcd:
  local:
   ...
    extraArgs:
      advertise-client-urls: "https://192.168.56.101:2379"
      listen-client-urls: "https://192.168.56.101:2379,https://127.0.0.1:2379"
   ...

Also see the ClusterConfiguration documentation: https://godoc.org/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta1#LocalEtcd
