我在Centos7.4上安装了一个简单的两个成员（主，节点）k8s集群 关注https://www.linuxtechi.com/install-kubernetes-1-7-centos7-rhel7/
kubectl.exe get nodes
NAME STATUS ROLES AGE VERSION
x042.x.int.com Ready <none> 36m v1.10.1
x051.x.int.com Ready master 40m v1.10.1
我已安装：
一切看起来都很完美，我为grafana服务设置了NodePort
kubectl.exe get svc,pods
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
svc/graf-grafana NodePort 10.103.172.192 <none> 80:30598/TCP 33m

到目前为止一直很好但存在问题。
当我尝试访问时
$ curl x042.x.int.com:30598 -v
* STATE: INIT => CONNECT handle 0x600057990; line 1423 (connection #-5000)
* Rebuilt URL to: N.N.N.N:30598/
* Added connection 0. The cache now contains 1 members
* Trying N.N.N.N...
* TCP_NODELAY set
* STATE: CONNECT => WAITCONNECT handle 0x600057990; line 1475 (connection #0)
但当我 ssh 到实际节点
时ssh x042.x.int.com or ssh x051.x.int.com
我可以轻松访问
curl x042.x.int.com:30598 -v
我会得到回应我期待
