安装K8S

参考:

Centos7安装Docker详细步骤(无坑版教程) - 腾讯云开发者社区-腾讯云

CentOS7 安装 k8s_BY&Crystal的博客-CSDN博客_centos7安装k8s

 

废话不多说,直接开始:

 

一,准备

准备2个Centos7的虚拟机。

 

 

二,装docker(master和slave1)

1,更新

yum -y update

2,卸载旧docker

yum remove docker  docker-common docker-selinux docker-engine

3,安装需要的软件包

yum install -y yum-utils device-mapper-persistent-data lvm2

4,设置镜像源(阿里巴巴)

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

5,安装docker

yum -y install docker-ce-18.03.1.ce

或者查找后,自行安装其他版本

yum list docker-ce --showduplicates | sort -r

 查看docker版本

docker version

6,启动

systemctl start docker
systemctl enable docker

 

三,安装k8s

1,安装epel-release源(master和slave1)

yum -y install epel-release

2,关闭防火墙(master和slave1)

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

 

四,安装master机器

1,安装kubernetes-master

yum -y install etcd kubernetes-master

2,编辑 etcd.conf

vi /etc/etcd/etcd.conf

修改如下 

 

 3,修改 apiserver

vi /etc/kubernetes/apiserver

 

 

 

4,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

 

5,在etcd中定义flannel网络

etcdctl mk /atomic.io/network/config ‘{“Network”:“172.17.0.0/16”}’

 

五,安装slave机器

1,安装kubernetes-node

yum -y install flannel kubernetes-node

 

2,为flannel网络指定etcd服务

vi /etc/sysconfig/flanneld

 

 

3,修改config

vi /etc/kubernetes/config

 

 

 

4,kubelet配置文件

vim /etc/kubernetes/kubelet

 

 

5,slave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

 

六,查看

master机器,执行

kubectl get nodes
