master: 10.6.2.170 #master节点兼做仓库

node-1: 10.6.2.171

node-2: 10.6.2.172

1、添加host解析

# cat <
     
      >/etc/hosts10.6.2.170  master workstation10.6.2.171  node-110.6.2.172  node-2EOF

2、安装master节点

第1步：配置安装并配置kubenetes-master相关的配置文件

# yum install etcd  kubernetes-master  flannel -y # vim /etc/etcd/etcd.conf      #第1步:修改etcd的配置文件，要修改2处，IP地址指向自己 ETCD_LISTEN_CLIENT_URLS="http://10.6.2.170:2379" ETCD_ADVERTISE_CLIENT_URLS="http://10.6.2.170:2379"

# vim /etc/kubernetes/config    #是一个共同的配置文件所有的服务共用这个配置，主要配置日志、API Server、root权限等，指向master KUBE_MASTER="--master=http://10.6.2.170:8080"

# vim /etc/kubernetes/apiserver     #修改以下配置，注释红色部份 KUBE_API_ADDRESS="--insecure-bind-address=10.6.2.170" KUBE_ETCD_SERVERS="--etcd-servers=http://10.6.2.170:2379" KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16" #KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota"

# vim /etc/kubernetes/controller-manager   #不需要修改# vim /etc/kubernetes/scheduler   #不需要修改

第2步：配置flannel网络

# vim /etc/sysconfig/flanneld     #修改flannel的配置文件 FLANNEL_ETCD_ENDPOINTS="HTTP://10.6.2.170:2379" FLANNEL_ETCD_PREFIX="/coreos.com/network"

# etcdctl -C http://10.6.2.170:2379 set /coreos.com/network/config '{"network":"192.168.0.0/16"}'   #修改flannel网络的网段# systemctl enable flanneld.service # systemctl start flanneld.service # systemctl restart docker

第3步：配置启动服务和测试

# systemctl enable etcd.service # systemctl start etcd# systemctl enable kube-apiserver.service # systemctl start kube-apiserver.service # systemctl enable kube-controller-manager.service # systemctl start kube-controller-manager.service # systemctl enable kube-scheduler.service # systemctl start kube-scheduler.service # kubectl get node -s 10.6.2.170:8080NAME      STATUS    AGEnode-1    Ready     34mnode-2    Ready     32m

3、安装node节点（2个节点配置一致）

# yum install kubernetes-node flannel -y# vim /etc/kubernetes/config KUBE_MASTER="--master=http://10.6.2.170:8080"# vim /etc/kubernetes/kubelet KUBELET_ADDRESS="--address=10.6.2.171"KUBELET_HOSTNAME="--hostname-override=node-1"KUBELET_API_SERVER="--api-servers=http://10.6.2.170:8080"#KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=registry.access.redhat.com/rhel7/pod-infrastructure:latest"  #注释这一行# vim /etc/sysconfig/flanneld FLANNEL_ETCD_ENDPOINTS="http://10.6.2.170:2379"FLANNEL_ETCD_PREFIX="/coreos.com/network"# systemctl enable flanneld.service # systemctl start flanneld.service # systemctl restart docker# systemctl enable kubelet# systemctl start kubelet# systemctl enable kube-proxy.service # systemctl restart kube-proxy.service
