1、节点规划

2、系统配置（所有机器）

• 关闭selinux 

• # 临时关闭$ setenforce 0 ?# 永久关闭$ vim /etc/selinux/config SELINUX=disabled

• 关闭且禁用防火墙

• $ systemctl stop firewalld 
  $ systemctl disable firewalld

• 修改hostname

• vi /ect/hostname# 四台机器分别修改为 masternode1node2etcd

• 修改hosts文件

• $ vim /etc/hosts127.0.0.1 ??localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.80.136 master192.168.80.137 node1192.168.80.138 node2192.168.80.139 etcd

• ssh免密登陆

• $ ssh-keygen ?# 一路回车默认即可$ ssh-copy-id ??{其他机器的ip}

• 更新yum

$ yum update

• 安装相关组件

• $ yum install -y etcd kubernetes ntp flannel

3、各节点配置

• etcd服务器

• # 修改配置文件$ vim /etc/etcd/etcd.conf ETCD_NAME=defaultETCD_DATA_DIR="/var/lib/etcd/default.etcd"ETCD_LISTEN_CLIENT_URLS="http://localhost:2379,http://192.168.80.139:2379"ETCD_ADVERTISE_CLIENT_URLS="http://192.168.80.139:2379"# 启动服务$ systemctl start etcd ??$ systemctl enable etcd#检查etcd cluster状态 $ etcdctl cluster-health ?member 8e9e05c52164694d is healthy: got healthy result from http://192.168.80.139:2379cluster is healthy
  
  # 设置一个key，下面会用到
  etcdctl set /k8s/network/config ‘{"Network": "10.255.0.0/16"}‘

• master服务器

• # ?配置kube-apiserver配置文件$ ?vim /etc/kubernetes/config KUBE_LOGTOSTDERR="--logtostderr=true"KUBE_LOG_LEVEL="--v=0"KUBE_ALLOW_PRIV="--allow-privileged=false"KUBE_MASTER="--master=http://192.168.80.136:8080"$ vim /etc/kubernetes/apiserverKUBE_API_ADDRESS="--insecure-bind-address=0.0.0.0"KUBE_ETCD_SERVERS="--etcd-servers=http://192.168.80.139:2379"KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16"KUBE_ADMISSION_CONTROL="--admission-control=AlwaysAdmit"KUBE_API_ARGS=""#配置kube-scheduler配置文件vim /etc/kubernetes/scheduler KUBE_SCHEDULER_ARGS="--address=0.0.0.0"# 启动服务for SERVICES in ?kube-apiserver kube-controller-manager kube-schedulerdo ????systemctl restart $SERVICESdone

• node1节点

• # 配置node1网络$ vim /etc/sysconfig/flanneld FLANNEL_ETCD_ENDPOINTS="http://192.168.80.139:2379"FLANNEL_ETCD_PREFIX="/k8s/network"FLANNEL_OPTIONS="--iface=ens33" ??# ens是当前可用上网的网卡名称# 配置node1 kube-proxy$ vim /etc/kubernetes/config KUBE_LOGTOSTDERR="--logtostderr=true"KUBE_LOG_LEVEL="--v=0"KUBE_ALLOW_PRIV="--allow-privileged=false"KUBE_MASTER="--master=http://192.168.80.136:8080"$ vim /etc/kubernetes/proxy ?????????????????KUBE_PROXY_ARGS="--bind=address=0.0.0.0"# 配置node1 kubelet$ vim /etc/kubernetes/kubelet KUBELET_ADDRESS="--address=127.0.0.1"KUBELET_HOSTNAME="--hostname-override=node1"KUBELET_API_SERVER="--api-servers=http://192.168.80.136:8080"KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=registry.access.redhat.com/rhel7/pod-infrastructure:latest"KUBELET_ARGS=""# 启动node1服务for SERVICES in flanneld kube-proxy kubelet; do ???systemctl restart $SERVICES ???systemctl enable $SERVICES ???systemctl status $SERVICES done

• node2节点

• # 配置node2网络$ vim /etc/sysconfig/flanneld FLANNEL_ETCD_ENDPOINTS="http://192.168.80.139:2379"FLANNEL_ETCD_PREFIX="/k8s/network"FLANNEL_OPTIONS="--iface=ens33" ???????# 配置node2 kube-proxy$ vim /etc/kubernetes/config KUBE_LOGTOSTDERR="--logtostderr=true"KUBE_LOG_LEVEL="--v=0"KUBE_ALLOW_PRIV="--allow-privileged=false"KUBE_MASTER="--master=http://192.168.80.136:8080"$ vim /etc/kubernetes/proxy ?????????????????KUBE_PROXY_ARGS="--bind-address=0.0.0.0"# 配置node2 kubelet$ vim /etc/kubernetes/kubelet KUBELET_ADDRESS="--address=127.0.0.1"KUBELET_HOSTNAME="--hostname-override=node1"KUBELET_API_SERVER="--api-servers=http://192.168.80.136:8080"KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=registry.access.redhat.com/rhel7/pod-infrastructure:latest"KUBELET_ARGS=""# 启动node2服务for SERVICES in flanneld kube-proxy kubelet docker; do ???systemctl restart $SERVICES ???systemctl enable $SERVICES ???systemctl status $SERVICES done

4、测试

[root@master ~]# kubectl get nodesNAME ?????STATUS ???AGEnode1 ????Ready ????55mnode2 ????Ready ????54m
