问题一：电脑打开某软件报错： “当前服务进程已退出关闭，请尝试重新启动SecoClientService服务或重新安装客户端！”

原因：后台服务未运行

解决方法：Win+R打开运行框-->输入services.msc后回车-->在服务列表中找到软件名+Service这个服务（显示被禁用了）-->右键选择“属性”-->将启动类型改为“自动”-->确定

问题二：kubectl初始化失败

报错：pod43195cb4486390800518511f0ab05660.slice: unknown” pod=“kube-system/kube-scheduler-master”
May 23 10:44:00 master kubelet[106272]: E0523 10:44:00.235720 106272 kuberuntime_manager.go:782] “CreatePodSandbox for pod failed” err=“rpc error: code = Unknown desc = failed to start sandbox container for pod "kube-scheduler-master": Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: invalid slice name: /kubepods.slice/kubepods-burstable.slice/kubepods-burstable-pod43195cb4486390800518511f0ab05660.slice: unknown” pod=“kube-system/kube-scheduler-master”

原因：使用不兼容的 cgroup 造成的

解决方法：

在/etc/docker/daemon.json文件中加入"exec-opts": ["native.cgroupdriver=systemd"]这行

然后执行：

mv /etc/docker/daemon.json /etc/docker/daemon.bak

systemctl stop docker

systemctl start docker

systemctl restart kubelet

问题三：k8s kubelet 服务无法启动报 code=exited, status=1/FAILURE错误

原因：通过 journalctl -f -u kubelet 查看日志发现没有禁用swap分区导致kubectl启动失败

解决方法：

执行：swapoff -a

然后重启kubectl：systemctl restart kubelet

问题四：Couldn’t get current server API group list: Get “http://localhost:8080/api?timeout=32s”: dial tcp 127.0.0.1:8080: connect: connection refused

原因：需要配置kubectl

解决方法，在master执行如下命令修复错误：

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

问题五：某次运行kubectl get pods，报错connection refuse

原因： 通过 journalctl -f -u kubelet 查看日志发现找不到/etc/kubenetes/kube-config文件

解决方法：手动重新生成了一个

问题六：kubectl无法与apiserver服务器通信

原因：这个错误原因比较低级，k8s没有安装api-server插件

解决方法：安装api-server插件

PS：这些问题有的解决方法并不详细，本人明天补充（有些资料在另一个电脑上）
