当看到有这个[提示][Link 1]的时候“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)”，应该就能猜出是配置参数哪里有问题了

参考这个文章，debug测试  
[https://mp.csdn.net/mdeditor/90116634\#][https_mp.csdn.net_mdeditor_90116634]  
挖出命令并补全（参数在这两个文件/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

如图找到了[关键][Link 1]信息。找到配置文件对比一下，原来是字符有问题，将所有参数相关字符修改并检查再次启动正常。
