21行：ETCD_ADVERTISE_CLIENT_URLS="http://10.0. 0.11:2379" 

启动

[root@k8s-master ~]# systemctl start etcd.service 

查看

etcdctl -C http://10.0.0.11:2379 cluster-health

 

二、安装k8s

[root@k8s-master ~]# yum install kubernetes-master.x86_64 -y
 

配置k8s

vim /etc/kubernetes/apiserver 

8行:  KUBE_API_ADDRESS="--insecure-bind-address=0.0.0.0"

systemctl enable kube-apiserver.service

systemctl restart kube-apiserver.service

systemctl enable kube-controller-manager.service

systemctl restart kube-controller-manager.service

systemctl enable kube-scheduler.service

systemctl restart kube-scheduler.service
