K8s环境搭建

一、基础环境准备

VMware虚拟机，安装三台CentOS，网络环境选择NAT模式，推荐配置如下（具体安装步骤省略，网上很多虚拟机安装CentOS7的教程）

二、网络环境说明

使用NAT模式，我的IP分别是：

master: 192.168.19.58

node1: 192.168.19.59

node2: 192.168.19.60

三、修改hostname

master主机：

hostnamectl set-hostname master

同理修改node1、node2节点主机名

设置hostname解析，注意，此时IP与主机名必须一一对应，三台主机都要执行下面命令

  1. cat <<EOF >>/etc/hosts
  2. 192.168.19.58 master
  3. 192.168.19.59 node1
  4. 192.168.19.60 node2
  5. EOF

四、k8s安装基础环境准备

4.1 安装docker-ce (所有机器都要安装)

  1. # 安装docker所需的工具
  2. yum install -y yum-utils device-mapper-persistent-data lvm2

  1. # 配置阿里云的docker源
  2. yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

  1. # 指定安装这个版本的docker-ce
  2. yum install -y docker-ce-18.09.9-3.el7

  1. # 启动docker
  2. systemctl enable docker && systemctl start docker

4.2 防火墙及内核设置（所有机器）

  1. # 关闭防火墙
  2. systemctl disable firewalld
  3. systemctl stop firewalld

  1. # 关闭selinux
  2. # 永久关闭 修改/etc/sysconfig/selinux文件设置
  3. sed -i 's/SELINUX=permissive/SELINUX=disabled/' /etc/sysconfig/selinux
  4. sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

  1. # 禁用交换分区
  2. swapoff -a
  3. # 永久禁用，打开/etc/fstab注释掉swap那一行。
  4. sed -i 's/.*swap.*/#&/' /etc/fstab

  1. # 修改内核参数
  2. cat <<EOF >  /etc/sysctl.d/k8s.conf
  3. net.bridge.bridge-nf-call-ip6tables = 1
  4. net.bridge.bridge-nf-call-iptables = 1
  5. EOF
  6. sysctl --system

五、K8s安装

5.1.1 master管理节点安装 kubeadm、kubelet、kubectl

  1. # 执行配置k8s阿里云源
  2. cat <<EOF > /etc/yum.repos.d/kubernetes.repo
  3. [kubernetes]
  4. name=Kubernetes
  5. baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
  6. enabled=1
  7. gpgcheck=1
  8. repo_gpgcheck=1
  9. gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
  10. EOF

  1. # 安装kubeadm、kubectl、kubelet
  2. yum install -y kubectl-1.16.0-0 kubeadm-1.16.0-0 kubelet-1.16.0-0

  1. # 启动kubelet服务
  2. systemctl enable kubelet && systemctl start kubelet

5.1.2 初始化K8s

执行以下命令初始化k8s，注意--apiserver-advertise-address 后面的IP为master的主机ip，这条命令执行慢，需要等待两三分钟

 kubeadm init --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.16.0 --apiserver-advertise-address 192.168.19.58 --pod-network-cidr=10.244.0.0/16 --token-ttl 0

上面安装完后，会提示你输入如下命令，复制粘贴过来，执行即可。

  1. mkdir -p $HOME/.kube
  2. sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  3. sudo chown $(id -u):$(id -g) $HOME/.kube/config
  4.  
  5. #node节点加入集群命令 
  6. kubeadm join 192.168.19.58:6443 --token zldsi8.6sicvcn5m7ztbowk \
  7.     --discovery-token-ca-cert-hash sha256:00f4508573d5a303dc6aa075cb5d96e68d509522e5a5c93e9940b79ea9bb7b0d

以上，安装master节点完毕。可以使用kubectl get nodes查看一下，此时master处于NotReady状态，暂时不用管。

5.2 node节点配置

5.2.1 node节点安装 kubeadm、kubelet

安装步骤和上面master节点安装一样

  1. # 执行配置k8s阿里云源
  2. cat <<EOF > /etc/yum.repos.d/kubernetes.repo
  3. [kubernetes]
  4. name=Kubernetes
  5. baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
  6. enabled=1
  7. gpgcheck=1
  8. repo_gpgcheck=1
  9. gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
  10. EOF
  11.  
  12. # 安装kubeadm、kubectl、kubelet
  13. yum install -y  kubeadm-1.16.0-0 kubelet-1.16.0-0
  14.  
  15. # 启动kubelet服务
  16. systemctl enable kubelet && systemctl start kubelet

5.2.2 node节点加入集群

这里加入集群的命令每个人都不一样，master节点安装配置好后，会返回加入集群的命令，如果忘记，可以登录master节点，使用kubeadm token create --print-join-command 来获取。获取后执行如下。

节点配置完成后，在master主机上，执行kubectl get nodes 可查勘节点

六、插件安装

6.1 安装calico （master机器）

  1. yum install wget
  2. wget https://kuboard.cn/install-script/calico/calico-3.9.2.yaml
  3. export POD_SUBNET=10.244.0.0/16
  4. sed -i "s#192\.168\.0\.0/16#${POD_SUBNET}#" calico-3.9.2.yaml
  5. kubectl apply -f calico-3.9.2.yaml

6.2 安装flannel（master机器）

  1. mkdir -p ~/k8s/
  2. cd ~/k8s
  3. curl -O https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yaml
  4. kubectl apply -f kube-flannel.yml

由于kube-flannel.yml 文件为国外地址，而且国内访问不了，所以将配置文件内容放在文末，可以直接创建文件，将内容复制粘贴进去。

执行完成后，在master主机上执行 kubectl get node 如果状态为Ready状态即表示安装成功。

kube-flannel.yml
