1、目录(一)环境准备工作31.服务器要求32.安装网络组件33.配置网络信息3(二)安装docker服务41.docker安装包下载42.安装docker服务53.修改docker启动文件54.启动docker服务5(三)部署私有仓库51.镜像下载52.验证registry6(四)部署etcd服务61.防火墙策略修改62.node1上执行63.node2上执行74.node3上执行75.验证部署7(五)部署kube-apiserver服务81.先打开防火墙:82.node1运行以下命令83.node2运行以下命令84.node3运行以下命令95.验证运行情况9(六)部署kube-controll
2、er-manager, kube-scheduler, kube-kubelet, kube-proxy服务101.导入镜像到docker中102.上传docker私有仓库113.编辑kublelet脚本114.编辑kube-proxy.sh脚本125.创建程序目录136.复制kubernetes执行程序到程序/bin目录147.编辑kube-controller-manager启动模版文件148.编辑kube-scheduler.yaml启动模版文件159.执行kubelet.sh脚本1610.执行kube-proxy.sh脚本1611.集群配置16(七)验证集群完成情况17(一) 环境准备
3、工作1. 服务器要求server1: 10.10.23.1 centos7 server2: 10.10.24.1 centos7 server3: 10.10.25.1 centos7 需要部署以下服务docker、registry、etcd、pause-amd64、kube-apiserver、kube-controller-manager, kube-scheduler, kube-kubelet, kube-proxy2. 安装网络组件yum install net-tools yyum install bridge-utils y1. 关闭自带firewalld防火墙，安装iptab
4、les防火墙并启动systemctl stop firewalld.servicesystemctl disable firewalld.serviceyum install iptables-services -ysystemctl start iptables.servicesystemctl enable iptables.service3. 配置网络信息 使用Openstack虚拟机需要修改mtu为1454，默认为1500，宿主机不用设置mtu值，并创建kbr0桥接网卡增加bridge网卡配置，并修改为混杂模式重启网卡/etc/init.d/network restart(二) 安装d
5、ocker服务1. docker安装包下载https:/yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-1.12.1-1.el7.centos.x86_64.rpmhttps:/yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-selinux-1.12.1-1.el7.centos.noarch.rpm2. 安装docker服务yum localinstall -y docker-engine-selinux-1.12.1-1.el7.c
6、entos.noarch.rpmyum localinstall -y docker-engine-1.12.1-1.el7.centos.x86_64.rpm3. 修改docker启动文件4. 启动docker服务systemctl start docker.servicesystemctl enable docker.service(三) 部署私有仓库1. 镜像下载docker pull registry:2.5.1docker run d -v /work/docker/registry:/work/data/registry -privileged=true -e STORAGE_PA
