docker管理神器—kubernetes—安裝篇

標籤：docker管理神器—kubernetes—安裝篇

2.1、環境

master與minion都是使用centos 7的系統

修改hostname與hosts檔案：

centos-master：192.168.137.102

centos-minion1：192.168.137.100

centos-minion2:192.168.137.101

2.2、關閉防火牆：

#systemctl disable firewalld

#systemctl stop firewalld

2.3、修改iptables

把icmp-host-prohibited兩條注釋掉

vi /etc/sysconfig/iptables

650) this.width=650;" src="http://s4.51cto.com/wyfs02/M02/88/89/wKioL1f7SVbjyyVMAAA43BD1Jfw435.png-wh_500x0-wm_3-wmp_4-s_3759298428.png" title="d10aa19d-63ea-4474-b2a9-c828ed782f7b.png" alt="wKioL1f7SVbjyyVMAAA43BD1Jfw435.png-wh_50" />

重啟iptables

#systemctl restart iptables

2.2、安裝

centos 7 的源都有，可以使用yum安裝

這裡使用阿里的鏡像：

#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

master端：

yum -y install etcd kubernetes-master

2.3、修改docker設定檔

vi /etc/sysconfig/docker

添加： 

OPTIONS=‘--selinux-enabled=false --insecure-registry gcr.io‘

2.4、修改apiserve設定檔

vi /etc/kubernetes/apiserver

刪除代碼中的ServiceAccount

KUBE_ADMISSION_CONTROL="--admission_control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota"

650) this.width=650;" src="http://s5.51cto.com/wyfs02/M02/88/8C/wKiom1f7SufilDbdAABHUuCPT2Y510.png" title="q.png" alt="wKiom1f7SufilDbdAABHUuCPT2Y510.png" />

2.5、修改config檔案

 vi /etc/kubernetes/config

650) this.width=650;" src="http://s2.51cto.com/wyfs02/M02/88/8C/wKiom1f7SdqzKDwHAAAonmfsf9w282.png-wh_500x0-wm_3-wmp_4-s_4213309626.png" title="14553575-c514-413a-be11-b17490f2419b.png" alt="wKiom1f7SdqzKDwHAAAonmfsf9w282.png-wh_50" />

2.6、啟動服務

使用指令碼

vi master_start.sh

#!/bin/bash

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

    systemctl restart $SERVICES

    systemctl enable $SERVICES

    systemctl status $SERVICES

done

設定許可權：

chmod +x master_start.sh

啟動：

./master_start.sh

2.7、停止服務腳本

vi master_stop.sh

#!/bin/bash

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

    systemctl stop $SERVICES

done

設定許可權：

chmod +x master_stop.sh

minion端安裝：（這裡只用centos-minion1）

2.8、yum安裝

yum install kubernetes-node

2.9、修改設定檔

vi /etc/kubernetes/config

650) this.width=650;" src="http://s5.51cto.com/wyfs02/M01/88/89/wKioL1f7Sj3Cw7EyAAApbpd6qWQ081.png" title="13c44ccb-6fea-4db7-a6db-ed6189ff59f3.png" alt="wKioL1f7Sj3Cw7EyAAApbpd6qWQ081.png" />

 2.10、配置kubelet檔案

vi /etc/kubernetes/kubelet

650) this.width=650;" src="http://s2.51cto.com/wyfs02/M01/88/89/wKioL1f7Sn_gkYZPAABB9OapyCk905.png" title="9f01ec62-f498-4707-9218-cbcfa9366f94.png" alt="wKioL1f7Sn_gkYZPAABB9OapyCk905.png" />

2.11、啟動服務

vi minion_start.sh

#!/bin/bash

for SERVICES in kube-proxy kubelet docker; do

    systemctl restart $SERVICES

    systemctl enable $SERVICES

    systemctl status $SERVICES

done

設定許可權：

chmod +x minion_start.sh

啟動：

./minion_start.sh

2.12、停止指令碼

vi minion_stop.sh

#!/bin/bash

for SERVICES in kube-proxy kubelet docker; do

    systemctl stop $SERVICES

done

設定許可權：

chmod +x minion_stop.sh

2.13、檢查狀態

在master端使用命令檢查

#kubectl get nodes

#kubectl cluster-info
