三台机器 1台master ip地址为192.168.91.133 2台node ip地址为192.168.91.134和192.168.91.135

1.公共部分

所有机器安装epel-release源

yum -y install epel-release

安装vim

yum -y install vim*

所有机器关闭防火墙

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
#查看防火墙状态
firewall-cmd --state

2.Master节点

使用yum安装etcd、kubernetes-master

yum -y install etcd kubernetes-master

编辑/etc/etcd/etcd.confetcd.conf文件

vim /etc/etcd/etcd.conf

ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"
ETCD_NAME="default"
ETCD_ADVERTISE_CLIENT_URLS="http://localhost:2379"

编辑/etc/kubernetes/apiserver文件

vim /etc/kubernetes/apiserver

KUBE_API_ADDRESS="--insecure-bind-address=0.0.0.0"
KUBE_API_PORT="--port=8080"
KUBELET_PORT="--kubelet-port=10250"
KUBE_ETCD_SERVERS="--etcd-servers=http://127.0.0.1:2379"
KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16"
KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ResourceQuota"

启动etcd、kube-apiserver、kube-controller-manager、kube-scheduler等服务，并设置开机启动

for SERVICES in etcd kube-apiserver kube-controller-manager kube-scheduler; do systemctl restart $SERVICES;systemctl enable $SERVICES;systemctl status $SERVICES ; done;

在etcd中定义flannel网络

etcdctl mk /atomic.io/network/config '{"Network":"172.17.0.0/16"}'

3.Node节点

在node机上安装kubernetes Node和flannel组件应用

yum -y install flannel kubernetes-node

为flannel网络指定etcd服务，修改/etc/sysconfig/flanneld文件

// 修改为Master机IP
FLANNEL_ETCD_ENDPOINTS="http://192.168.91.133:2379"

修改/etc/kubernetes/config文件

// 修改为Master机IP
KUBE_MASTER="--master=http://192.168.91.133:8080"

修改node机的kubelet配置文件/etc/kubernetes/kubelet

KUBELET_ADDRESS="--address=0.0.0.0"
KUBELET_PORT="--port=10250"
// 本机IP
KUBELET_HOSTNAME="--hostname-override=192.168.91.134"
// 主机IP
KUBELET_API_SERVER="--api-servers=http://192.168.91.133:8080"

node节点机上启动kube-proxy,kubelet,docker,flanneld等服务，并设置开机启动

for SERVICES in kube-proxy kubelet docker flanneld;do systemctl restart $SERVICES;systemctl enable $SERVICES;systemctl status $SERVICES; done;

在master主机上192.168.26.227执行如下命令，查看运行的node节点机器：

kubectl get nodes
