1.环境准备

所有节点做好host解析

[root@localhost ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.64.129  k8s-master
192.168.64.130  k8s-node1
192.168.64.131  k8s-node2
[root@localhost ~]# 

2. MASTER 节点安装etcd

yum install etcd -y
vim /etc/etcd/etcd.conf 
6行：ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"
21行：ETCD_ADVERTISE_CLIENT_URLS="http://192.168.64.129:2379"    # etcd的节点及占用端口

systemctl restart etcd.service 
systemctl enable etcd.service

3.安装kubernetes-master

[root@localhost ~]# yum install -y kubernetes-master.x86_64
#修改apiserver配置文件
[root@k8s-master ~]# vim /etc/kubernetes/apiserver 
KUBE_API_ADDRESS="--insecure-bind-address=0.0.0.0"
KUBE_API_PORT="--port=8080"
KUBE_ETCD_SERVERS="--etcd-servers=http://192.168.64.129:2379"     # etcd  地址及端口
KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,
SecurityContextDeny,ResourceQuota"

[root@k8s-master ~]# vim /etc/kubernetes/config
KUBE_MASTER="--master=http://192.168.64.128:8080"    #k8s 主节点


#重启服务
systemctl restart kube-apiserver.service 
systemctl enable kube-apiserver.service 
systemctl restart kube-controller-manager.service 
systemctl enable kube-controller-manager.service 
systemctl restart kube-scheduler.service 
systemctl enable kube-scheduler.service 

## 查看服务是否安装正常
[root@k8s-master ~]# kubectl get componentstatus 
NAME                 STATUS    MESSAGE             ERROR
scheduler            Healthy   ok                  
controller-manager   Healthy   ok                  
etcd-0               Healthy   {"health":"true"}   

node 节点安装kubernets

yum install kubernetes-node.x86_64 -y

vim /etc/kubernetes/config 
22行：KUBE_MASTER="--master=http://192.168.64.129:8080"
​
vim /etc/kubernetes/kubelet
5行：KUBELET_ADDRESS="--address=0.0.0.0"
8行：KUBELET_PORT="--port=10250"
11行：KUBELET_HOSTNAME="--hostname-override=192.168.64.130"
14行：KUBELET_API_SERVER="--api-servers=http://192.168.64.129:8080"

#重启服务
systemctl enable kubelet.service
systemctl restart kubelet.service
systemctl enable kube-proxy.service
systemctl restart kube-proxy.service

#docker也启动了
systemctl status docker

在k8s-master节点上检查

[root@k8s-master ~]# kubectl get node
NAME             STATUS    AGE
192.168.64.130   Ready     13h
192.168.64.131   Ready     13h

所有节点配置flanne 网络

yum install -y flannel 
[root@ ~]#: vi /etc/sysconfig/flanneld
FLANNEL_ETCD_ENDPOINTS="http://192.168.64.129:2379"    #etcd的端口及地址
