當看到有這個提示的時候“ExecStart=/usr/bin/kube-apiserver $KUBE_LOGTOSTDERR $KUBE_LOG_LEVEL $KUBE_ETCD_SERVERS $KUBE_API_ADDRESS $KUBE_API_PORT $KUBELET_PORT $KUBE_ALLOW_PRIV $KUBE_SERVICE_ADDRESSES $KUBE_ADMISSION_CONTROL $KUBE_API_ARGS (code=exited, status=2)”，應該就能猜出是配置參數哪裏有問題了

參考這個文章，debug測試
https://mp.csdn.net/mdeditor/90116634#
挖出命令並補全（參數在這兩個文件/etc/kubernetes/config和/etc/kubernetes/apiserver）：

/usr/bin/kube-apiserver --logtostderr=true --v=0 --etcd-servers=http://127.0.0.1:2379 --address=0.0.0.0 -–port=8080 –kubelet_port=10250 allow-privileged=false -–service-cluster-ip-range=10.254.0.0/16 --admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResouceQuota

如圖找到了關鍵信息。找到配置文件對比一下，原來是字符有問題，將所有參數相關字符修改並檢查再次啓動正常。
