15.linux上安装kubectl和Minikube

1.安装kubectl

kubectl是负责与k8s集群talk的工具,就像docker cli对话docker集群一样

地址:

https://kubernetes.io/docs/tasks/tools/install-kubectl/

Linux环境

步骤:

  • 下载kubectl文件(因为涉及到翻墙的问题,此下载方式可能不成功)
curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl

 可以查询一下kubectl文件最新版本号

https://storage.googleapis.com/kubernetes-release/release/stable.txt

比如v1.19.3,然后复制地址去迅雷下载kubectl文件,下载好的kubectl文件是一个二进制文件

https://storage.googleapis.com/kubernetes-release/release/v1.19.3/bin/linux/amd64/kubectl

然后通过ftp工具,将下载好的kubectl文件上传到   “/”目录下,再执行下面的操作。

  • 授予权限
chmod +x ./kubectl
  • 移动到自己指定的目录
sudo mv ./kubectl /usr/local/bin/kubectl
  • 测试是否安装成功
[root@localhost ~]# kubectl version

Client Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.0", GitCommit:"e19964183377d0ec2052d1f1fa930c4d7575bd50", GitTreeState:"clean", BuildDate:"2020-08-26T14:30:33Z", GoVersion:"go1.15", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server localhost:8080 was refused - did you specify the right host or port?

2.安装Docker

  • 安装依赖包
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
  • 设置阿里云镜像源
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
  • 安装 Docker-CE
sudo yum install docker-ce
  • 启动docker
# 开机自启
sudo systemctl enable docker 
# 启动docker服务  
sudo systemctl start docker
  • 重启服务docker
systemctl daemon-reload
systemctl restart docker.service

3.安装Minikube

依赖virtualbox,会在virtualbox里面安装虚拟机,虚拟机会安装好k8s单节点的集群。

  • 下载
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

 下载不了就用迅雷下载,再用ftp上传到服务器

如果是迅雷自己下载的文件,则执行下面命令

mv minikube-linux-amd64 minikube
chmod +x minikube
sudo mv minikube /usr/local/bin/
  •   启动
minikube start

报异常:

[root@localhost ~]# minikube start
* Centos 7.8.2003 上的 minikube v1.14.2
* Automatically selected the docker driver
* The "docker" driver should not be used with root privileges.
* If you are running minikube within a VM, consider using --driver=none:
*   https://minikube.sigs.k8s.io/docs/reference/drivers/none/

X Exiting due to DRV_AS_ROOT: The "docker" driver should not be used with root privileges.

如出现:The "docker" driver should not be used with root privileges.
不允许以root用户运行minikube,请创建一个新用户,然后与该用户一起运行,并确保将该用户添加到docker组。

  • 创建用户
useradd taizhuyj
passwd taizhuyj
su taizhuyj
  • 将新用户添加到docker组
sudo usermod -aG docker $USER && newgrp docker

执行命令出错

用户名 不在 sudoers文件中,此事将被报告

su root

visudo

root    ALL=(ALL:ALL) ALL
linc    ALL=(ALL:ALL) ALL   // 添加此行保存


su taizhuyj
  • 再执行即可
sudo usermod -aG docker $USER && newgrp docker
  •  启动Minikube
