centos7 搭建k8s

$ master：172.31.142.129
$ node：172.31.142.130

$ yum -y install epel-release
$ systemctl stop firewalld
$ systemctl disable firewalld
$ setenforce 0
# 查看防火墙状态
$ firewall-cmd --state

一、master主机

$ yum -y install etcd kubernetes-master

$ vim /etc/etcd/etcd.conf

$ vim /etc/kubernetes/apiserver
# 删除了ServiceAccout参数

# 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"}'

二、node主机

$ yum -y install flannel kubernetes-node

$ vim /etc/sysconfig/flanneld

image.png

$ vim /etc/kubernetes/config

image.png

$ vim /etc/kubernetes/kubelet

image.png

# 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

三、 查看节点 ，在master上执行

$ kubectl get nodes
