1,安装docker
64 位版本的 CentOS 7
CentOS 系统的内核版本高于 3.10（uname -r命令可查看系统内核版本）
安装 Docker CE
设置 Docker 的镜像仓库并从中进行安装
下载 RPM 软件包并手动进行安装（例如，在不能访问互联网的隔离系统中安装 Docker）
1.从镜像仓库安装
确保 yum 包更新到最新:
sudo yum update
安装一些必要的系统工具：
yum-utils 提供了 yum-config-manager 实用程序，用于设置yum源
devicemapper 存储驱动需要 device-mapper-persistent-data 和 lvm2
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
设置镜像仓库：
阿里云仓库地址（推荐）
sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker- ce.repo
官方仓库地址
sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
更新 yum 软件包索引。
sudo yum makecache fast
查看仓库中所有docker版本
sudo yum list docker-ce --showduplicates | sort -r
安装 Docker CE 最新版本：sudo yum install docker-ce
sudo yum install docker-ce
安装 Docker-ce 指定版本：sudo yum install docker-ce-版本号
sudo yum -y install docker-ce-18.03.1.ce-1.el7.centos
启动 Docker
sudo systemctl start docker 启动
sudo systemctl restart docker 重启
sudo systemctl enable docker 加入开机启动
Docker 版本信息查看
sudo docker version
测试运行 hello-world
sudo docker run hello-world
docekr拉取hello-world镜像并启动，后打印出Hello from Docker!
查看安装的docker
yum list installed | grep docker
卸载 Docker CE
sudo yum remove docker-ce
删除所有镜像、容器和存储卷
sudo rm -rf /var/lib/docker
2.0 安装golang：
下载安装包，国内地址：https://studygolang.com/dl/golang/go1.14.4.linux-amd64.tar.gz
$ sudo tar -C /usr/local -xzf go1.12.5.linux-amd64.tar.gz //解压
添加环境变量，修改/etc/profile 或$HOME/.profile或/etc/profile.d/目录的文件
$ sudo vi /etc/profile.d/brianconfig.sh //添加以下内容
export GOROOT=/usr/local/go //定义GOROOT
export PATH=$PATH:/usr/local/go/bin // 添加go/bin到系统环境变量PATH中
export GOPATH=/home/gopath //添加GOPATH变量
查看golang版本：
$ go version
go version go1.12.5 linux/amd64
查看GOROOT
$ go env GOROOT
/usr/local/go
查看GOPATH
$ echo $GOPATH
/
/home/gopath
3.0 安装node：
1、从官网下下载最新的nodejs，https://nodejs.org/dist/v12.18.2/node-v12.18.2-linux-x64.tar.xz
image
历史版本可从https://nodejs.org/dist/下载
2、解压安装包
tar -xvf node-v10.16.0-linux-x64.tar.xz
sudo tar -C /usr/local -xzf go1.14.4.linux-amd64.tar.gz
3、移动并改名文件夹（不改名也行）
cd /usr/local/
mv node-v12.18.2-linux-x64 /usr/local/
mv node-v10.16.0.0-linux-64/ nodejs
image
4、让npm和node命令全局生效
软链接方式（推荐）
ln -s /usr/local/nodejs/bin/npm /usr/local/bin/
ln -s /usr/local/nodejs/bin/node /usr/local/bin/
5、查看nodejs是否安装成功
node -v
npm -v
image
4.0. 安装k8s
1 系统准备
查看系统版本
[root@localhost]# cat /etc/centos-release

添加阿里源
[root@localhost ~]# rm -rfv /etc/yum.repos.d/*
[root@localhost ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo
配置主机名
[root@master01 ~]# cat /etc/hosts

192.168.122.21 master01.paas.com master01
关闭swap，注释swap分区
[root@master01 ~]# swapoff -a
[root@master01 ~]# cat /etc/fstab
#
# /etc/fstab

EOF
sysctl --system
2 安装常用包
[root@master01 ~]# yum install vim bash-completion net-tools gcc -y
4 安装kubectl、kubelet、kubeadm
添加阿里kubernetes源
[root@master01 ~]# cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/

repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
安装
[root@master01 ~]# yum install kubectl kubelet kubeadm
[root@master01 ~]# systemctl enable kubelet
5 初始化k8s集群
image.png
[root@master01 ~]# kubeadm init --kubernetes-version=1.18.0 \
--apiserver-advertise-address=192.168.122.21 \
--image-repository registry.aliyuncs.com/google_containers \
--service-cidr=10.10.0.0/16 --pod-network-cidr=10.122.0.0/16
POD的网段为: 10.122.0.0/16， api server地址就是master本机IP。
这一步很关键，由于kubeadm 默认从官网k8s.grc.io下载所需镜像，国内无法访问，因此需要通过–image-repository指定阿里云镜像仓库地址。
集群初始化成功后返回如下信息：

Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.122.21:6443 --token v2r5a4.veazy2xhzetpktfz \
--discovery-token-ca-cert-hash sha256:daded8514c8350f7c238204979039ff9884d5b595ca950ba8bbce80724fd65d4
[root@master01 ~]#
记录生成的最后部分内容，此内容需要在其它节点加入Kubernetes集群时执行。
根据提示创建kubectl
[root@master01 ~]# mkdir -p $HOME/.kube
[root@master01 ~]# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
[root@master01 ~]# sudo chown $(id -u):$(id -g) $HOME/.kube/config
执行下面命令，使kubectl可以自动补充
[root@master01 ~]# source <(kubectl completion bash)
查看节点，pod
