对应主机名 写入 hosts

centos-master = 192.168.121.9
centos-minion-1 = 192.168.121.65
centos-minion-2 = 192.168.121.66
centos-minion-3 = 192.168.121.67

关闭所有主机防火墙

setenforce 0
systemctl disable iptables-services firewalld
systemctl stop iptables-services firewalld

对应所有主机 建立 repo 源

[virt7-docker-common-release]
name=virt7-docker-common-release
baseurl=http://cbs.centos.org/repos/v…
gpgcheck=0

对应所有主机安装修改
yum -y install –enablerepo=virt7-docker-common-release kubernetes etcd flannel

vi /etc /kubernetes/config
KUBE_LOGTOSTDERR=”–logtostderr=true”

KUBE_LOG_LEVEL=”–v=0″

KUBE_ALLOW_PRIV=”–allow-privileged=false”

KUBE_MASTER=”–master=http://centos-master:8080″

对master主机
vi /etc/etcd/etcd.conf
ETCD_NAME=default
ETCD_DATA_DIR=”/var/lib/etcd/default.etcd”
ETCD_LISTEN_CLIENT_URLS=”http://0.0.0.0:2379″
ETCD_ADVERTISE_CLIENT_URLS=”http://0.0.0.0:2379″

vi /etc/kubernetes/apiserver

KUBE_API_ADDRESS=”–address=0.0.0.0″

KUBE_API_PORT=”–port=8080″

KUBELET_PORT=”–kubelet-port=10250″

KUBE_ETCD_SERVERS=”–etcd-servers=http://centos-master:2379″

KUBE_SERVICE_ADDRESSES=”–service-cluster-ip-range=10.254.0.0/16″

KUBE_API_ARGS=””

启动ETCD并将其配置为在主机上保持网络覆盖配置： 警告此网络必须在您的网络基础架构中未使用！172.30.0.0/16在我们的网络中是免费的。
systemctl start etcd
etcdctl mkdir /kube-centos/network
etcdctl mk /kube-centos/network/config “{ “Network”: “172.30.0.0/16”, “SubnetLen”: 24, “Backend”: { “Type”: “vxlan” } }”

vi /etc/sysconfig/flanneld
FLANNEL_ETCD_ENDPOINTS=”http://centos-master:2379″

FLANNEL_ETCD_PREFIX=”/kube-centos/network” 这个是上面创建的 kube-centos

最后
for SERVICES in etcd kube-apiserver kube-controller-manager kube-scheduler flanneld; do

systemctl restart $SERVICES
systemctl enable $SERVICES
systemctl status $SERVICES

done

Node
在节点上配置Kubernetes服务。
我们需要配置kubelet并启动kubelet和代理
vi /etc/kubernetes/kubelet
KUBELET_ADDRESS=”–address=0.0.0.0″

KUBELET_PORT=”–port=10250″

KUBELET_HOSTNAME=”–hostname-override=centos-minion-n” 写各自的IP

KUBELET_API_SERVER=”–api-servers=http://centos-master:8080″ 写master的ip

KUBELET_ARGS=””

vi /etc/sysconfig/flanneld
FLANNEL_ETCD_ENDPOINTS=”http://centos-master:2379″

FLANNEL_ETCD_PREFIX=”/kube-centos/network”

Start the appropriate services on node 开启服务
for SERVICES in kube-proxy kubelet flanneld docker; do

systemctl restart $SERVICES
systemctl enable $SERVICES
systemctl status $SERVICES

done

Configure kubectl
kubectl config set-cluster default-cluster –server=http://centos-master:8080 写 master ip
kubectl config set-context default-context –cluster=default-cluster –user=default-admin
kubectl config use-context default-context

最后 在 master 主机
kubectl get nodes

得到相应的主机信息
