解决etcd服务--listen-metrics-urls=http://127.0.0.1:2381

 1、查看etcd的2381端口

[root@master-node manifests]# netstat -anp|grep 2381
tcp        0      0 127.0.0.1:2381      0.0.0.0:*               LISTEN      21765/etcd 

2、获取etcd的pod

[root@master-node manifests]# kubectl get pod -A
NAMESPACE       NAME                                    READY   STATUS    RESTARTS   AGE
cattle-system   cattle-cluster-agent-7f9549666f-vmxg4   0/1     Error     316        28h
kube-system     coredns-6d56c8448f-q4z57                1/1     Running   19         2d4h
kube-system     coredns-6d56c8448f-zfkq6                1/1     Running   20         2d4h
kube-system     etcd-master-node                        1/1     Running   0          13m
kube-system     kube-apiserver-master-node              1/1     Running   19         2d4h
kube-system     kube-controller-manager-master-node     1/1     Running   140        2d4h
kube-system     kube-flannel-ds-676v4                   1/1     Running   1          2d4h
kube-system     kube-flannel-ds-7jgt4                   0/1     Error     345        47h
kube-system     kube-proxy-bplzt                        1/1     Running   3          2d4h
kube-system     kube-proxy-dlg4d                        1/1     Running   1          47h
kube-system     kube-scheduler-master-node       

3、查看etcd的​​pod​​详细信息

[root@master-node manifests]# kubectl describe pod etcd-master-node -n kube-system

 4、编辑etcd.yaml

vi /etc/kubernetes/manifests/etcd.yaml 

 5、验证
