作者:电脑系统

第三个节点

KUBE_ALLOW_PRIV="--allow-privileged=false"

yum -y install etcd kubernetes

KUBE_LOG_LEVEL=``"--v=0"

5.在富有Node节点上运营kube-proxy,kubelet,docker,flanneld等劳务,并安装开机运行

KUBELET_API_SERVER="--api_servers="

一.安装配置Kubernetes Master 如下操作在master上实践1.使用yum安装etcd和kubernetes-master

3.编辑/etc/kubernetes/apiserver文件

monion01

ETCD_NAME=default
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"                
ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"             #监听客户地址的端口
ETCD_ADVERTISE_CLIENT_URLS="http://主ip:2379"        #通知客户的地址及端口

192.168.137.148 cmnode1

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

 

开发银行etcd、kube-apiserver、kube-controller-manager、kube-scheduler等劳动,并设置开机运行。

1.在monion01、monion02、monion03上部署

2.编辑/etc/etcd/etcd.conf文件

# systemctl status  kube-controller-manager.service

3.配置kubernetes

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

5.在etcd中定义flannel网络

flannel: 网络布局补助

2.为flannel网络钦定etcd服务,修改/etc/sysconfig/flanneld文件

192.168.137.147   Ready     7m

kube-proxy: kube-proxy是kubernetes 里运维在minion节点上的三个零件, 它起的效劳是二个服务代办的剧中人物

vim /etc/kubernetes/config

KUBELET_ARGS=""

NAME              STATUS    AGE

vi /etc/kubernetes/kubelet

5.在etcd中定义flannel网络

  - kubelet 在Node节点上依照布署文件中定义的器皿标准运维容器

monion03

yum -y install flannel kubernetes-node

4.早先etcd、kube-apiserver、kube-controller-manager、kube-scheduler等劳务,并安装开机运维。

etcd: 高可用存款和储蓄分享配置和劳务意识

 

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

KUBELET_HOSTNAME="--hostname_override=192.168.50.133"

 

设置配备Kubernetes Node

FLANNEL_ETCD=""

到此master端配置完结

三.验证集群是不是安装成功

192.168.137.212 cmnode3

vi /etc/kubernetes/apiserver

  systemctl restart $SERVICES;

# systemctl status  etcd.service

kube-scheduler: Kubernetes scheduler的职能就是基于特定的调解算法将pod调节到钦赐的专业节点(minion)上,这一经过也叫绑定(bind)

cp /etc/kubernetes/config /etc/kubernetes/config.bak

Kubernetes集群组件:

KUBELET_HOSTNAME="--hostname_override=192.168.50.132"

do

3.修改/etc/kubernetes/config文件

#systemctl stop firewalld

for SERVICES in etcd kube-apiserver kube-controller-manager kube-scheduler;

# systemctl status  kube-scheduler.service

  - etcd 叁个高可用的K/V键值对存储和劳动意识系统

KUBE_ETCD_SERVERS="--etcd_servers="

二.设置配备Kubernetes Node

KUBELET_API_SERVER="--api-servers="     #指定Master节点的API Server

KUBELET_ADDRESS="--address=0.0.0.0"

在master上实践如下命令

KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16"

7.启动kube-apiserver  kube-controller-manager  kube-scheduler

# yum -y install etcd kubernetes-master

  - kube-controller-manager 确定保证集群服务

192.168.50.132   kubernetes.io/hostname=192.168.50.132   Ready

4.依照如下内容改换对应node的安排文件/etc/kubernetes/kubelet

192.168.137.199   Ready     7m

kubelet: Kubelet运维在Kubernetes Minion Node上. 它是container agent的逻辑继承者

FLANNEL_ETCD=""                                           #etcd运维在哪个服务器上
FLANNEL_ETCD_KEY="/atomic.io/network"

  - kube-apiserver 提供kubernetes集群的API调用

vi /etc/kubernetes/kubelet

do

4.遵守如下内容改动对应node的配置文件/etc/kubernetes/kubelet

2.禁用selinux

done

KUBELET_HOSTNAME="--hostname-override=192.168.137.148"             #修改成对应Node的IP

systemctl restart $SERVICES

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

  - kube-scheduler 调节容器,分配到Node

KUBELET_ARGS=""

解说:上述2个节点正常呈现,状态为Ready,则证实集群搭建成功。

9.查看节点

  systemctl restart $SERVICES;

2.为flannel互连网钦定etcd服务,修改/etc/sysconfig/flanneld文件

顾客端配置

第多少个节点

ETCD_ADVERTISE_CLIENT_URLS=""

KUBELET_API_SERVER="--api_servers="

  systemctl status $SERVICES;

在master上推行如下命令

ip a | grep flannel | grep inet

一般来说操作在node1、node2上施行

# yum -y install epel-release

monion02

5.在装有Node节点上运行kube-proxy,kubelet,docker,flanneld等劳务,并设置开机运营。

192.168.137.199 cmnode2

systemctl status $SERVICES

for SERVICES in kube-proxy kubelet docker flanneld;

1.使用yum安装etcd和kubernetes-master

setenforce 0
