问一下，我只有一个主节点，使用kainstall工具搭建的k8s，基本什么都没装，重启后虚机崩掉，拼命重启是什么原因啊 about kainstall

系统CentOS Linux release 7.9.2009 (Core)，安装命令是
bash kainstall-centos.sh
init
--master 192.168.133.180
--user root
--password 123456
--port 22
--version 1.20.6
重启之后 ，100%出现，还什么都没装，只是改了编辑 kube-apiserver.yaml文件
vi /etc/kubernetes/manifests/kube-apiserver.yaml的- --service-node-port-range=1-65535
