一. 为什么是k8s v1.16.0？

最新版的v1.16.2试过了，一直无法安装完成，安装到kubeadm init那一步执行后，报了很多错，如：node xxx not found等。centos7都重装了几次，还是无法解决。用了一天都没安装完，差点放弃。后来在网上搜到的安装教程基本都是v1.16.0的，我不太相信是v1.16.2的坑所以先前没打算降级到v1.16.0。没办法了就试着安装v1.16.0版本，竟然成功了。记录在此，避免后来者踩坑。

本篇文章，安装大步骤如下：
<ul>
<li>
安装docker-ce 18.09.9（所有机器）</li>
<li>
设置k8s环境前置条件（所有机器）</li>
<li>
安装k8s v1.16.0 master管理节点</li>
<li>
安装k8s v1.16.0 node工作节点</li>
<li>
安装flannel（master）</li>
</ul>

这里有重要的一步，请记住自己master和node之间通信的ip，如我的master的ip为192.168.99.104，node的ip为：192.168.99.105. 请确保使用这两个ip在master和node上能互相ping通，这个master的ip 192.168.99.104接下来配置k8s的时候需要用到。

我的环境：
<ul>
<li>
操作系统：win10</li>
<li>
虚拟机：virtual box</li>
<li>
linux发行版：CentOS7</li>
<li>
linux内核(使用uname -r查看)：3.10.0-957.el7.x86_64</li>
<li>
master和node节点通信的ip(master)：192.168.99.104</li>
</ul>

二. 安装docker-ce 18.09.9（所有机器）

所有安装k8s的机器都需要安装docker，命令如下：
<blockquote>

# 安装docker所需的工具 

yum install -y yum-utils device-mapper-persistent-data lvm2 

# 配置阿里云的docker源 

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 

# 指定安装这个版本的docker-ce 

yum install -y docker-ce-18.09.9-3.el7 

# 启动docker 

systemctl enable docker && systemctl start docker 
</blockquote>

三. 设置k8s环境准备条件（所有机器）

安装k8s的机器需要2个CPU和2g内存以上，这个简单，在虚拟机里面配置一下就可以了。然后执行以下脚本做一些准备操作。所有安装k8s的机器都需要这一步操作。
<blockquote>

# 关闭防火墙 

systemctl disable firewalld 

systemctl stop firewalld 

# 关闭selinux 

# 临时禁用selinux 

setenforce 0 

# 永久关闭修改/etc/sysconfig/selinux文件设置 

sed -i 's/SELINUX=permissive/SELINUX=disabled/' /etc/sysconfig/selinux 

sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config 

# 禁用交换分区 

swapoff -a 

# 永久禁用，打开/etc/fstab注释掉swap那一行。 

sed -i 's/.*swap.*/#&/' /etc/fstab 

# 修改内核参数 

cat <<EOF > /etc/sysctl.d/k8s.conf 

net.bridge.bridge-nf-call-ip6tables = 1 

net.bridge.bridge-nf-call-iptables = 1 

EOF 

sysctl --system 
</blockquote>

四. 安装k8s v1.16.0 master管理节点

如果还没安装docker，请参照本文步骤二安装docker-ce 18.09.9（所有机器）安装。如果没设置k8s环境准备条件，请参照本文步骤三设置k8s环境准备条件（所有机器）执行。

以上两个步骤检查完毕之后，继续以下步骤。

1. 安装kubeadm、kubelet、kubectl

由于官方k8s源在google，国内无法访问，这里使用阿里云yum源
<blockquote>

# 执行配置k8s阿里云源 

cat <<EOF > /etc/yum.repos.d/kubernetes.repo 

 

name=Kubernetes 

baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/ 

enabled=1 

gpgcheck=1 

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kubeadm、kubectl、kubelet 

yum install -y kubectl-1.16.0-0 kubeadm-1.16.0-0 kubelet-1.16.0-0 

# 启动kubelet服务 

systemctl enable kubelet && systemctl start kubelet 
</blockquote>

2. 初始化k8s 以下这个命令开始安装k8s需要用到的docker镜像，因为无法访问到国外网站，所以这条命令使用的是国内的阿里云的源(registry.aliyuncs.com/google_containers)。另一个非常重要的是：这里的--apiserver-advertise-address使用的是master和node间能互相ping通的ip，我这里是192.168.99.104，刚开始在这里被坑了一个晚上，你请自己修改下ip执行。这条命令执行时会卡在 You can also perform this action in beforehand using ''kubeadm config images pull，大概需要2分钟，请耐心等待。
<blockquote>

# 下载管理节点中用到的6个docker镜像，你可以使用docker images查看到 

# 这里需要大概两分钟等待，会卡在 You can also perform this action in beforehand using ''kubeadm config images pull 

kubeadm init --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.16.0 --apiserver-advertise-address 192.168.99.104 --pod-network-cidr=10.244.0.0/16 --token-ttl 0 
</blockquote>

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。
<blockquote>

# 上面安装完成后，k8s会提示你输入如下命令，执行 

mkdir -p $HOME/.kube 

sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config 

sudo chown $(id -u):$(id -g) $HOME/.kube/config 
</blockquote>

3. 记住node加入集群的命令上面kubeadm init执行成功后会返回给你node节点加入集群的命令，等会要在node节点上执行，需要保存下来，如果忘记了，可以使用如下命令获取。
<blockquote>

kubeadm token create --print-join-command 
</blockquote>

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。

五. 安装k8s v1.16.0 node工作节点

如果还没安装docker，请参照本文步骤二安装docker-ce 18.09.9（所有机器）安装。如果没设置k8s环境准备条件，请参照本文步骤三设置k8s环境准备条件（所有机器）执行。

以上两个步骤检查完毕之后，继续以下步骤。

1. 安装kubeadm、kubelet
<blockquote>

# 执行配置k8s阿里云源 

cat <<EOF > /etc/yum.repos.d/kubernetes.repo 

 

name=Kubernetes 

baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/ 

enabled=1 

gpgcheck=1 

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kubeadm、kubectl、kubelet 

yum install -y kubeadm-1.16.0-0 kubelet-1.16.0-0 

# 启动kubelet服务 

systemctl enable kubelet && systemctl start kubelet 
</blockquote>

2. 加入集群这里加入集群的命令每个人都不一样，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。
<blockquote>

# 加入集群，如果这里不知道加入集群的命令，可以登录master节点，使用kubeadm token create --print-join-command 来获取 

kubeadm join 192.168.99.104:6443 --token ncfrid.7ap0xiseuf97gikl \ 

 --discovery-token-ca-cert-hash sha256:47783e9851a1a517647f1986225f104e81dbfd8fb256ae55ef6d68ce9334c6a2 
</blockquote>

加入成功后，可以在master节点上使用kubectl get nodes命令查看到加入的节点。

六. 安装flannel（master机器）

以上步骤安装完后，机器搭建起来了，但状态还是NotReady状态，如下图，master机器需要安装flanneld。 

<img style="max-width:100%!important;height:auto!important;"title="CentOS安装K8S图文教程(一次性成功)" alt="CentOS安装K8S图文教程(一次性成功)" src="https://zhuji.jb51.net/uploads/img/202305/2e0fc7e5b30f8f3455658f08e060c12a.jpg">

1. 下载官方fannel配置文件使用wget命令，地址为：(https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml)，这个地址国内访问不了，所以我把内容复制下来，为了避免前面文章过长，我把它粘贴到文章末尾第八个步骤附录了。这个yml配置文件中配置了一个国内无法访问的地址(quay.io)，我已经将其改为国内可以访问的地址(quay-mirror.qiniu.com)。我们新建一个kube-flannel.yml文件，复制粘贴该内容即可。

2. 安装fannel
<blockquote>

kubectl apply -f kube-flannel.yml 
</blockquote>

七. 大功告成

至此，k8s集群搭建完成，如下图节点已为Ready状态，大功告成，完结撒花。

<img style="max-width:100%!important;height:auto!important;"title="CentOS安装K8S图文教程(一次性成功)" alt="CentOS安装K8S图文教程(一次性成功)" src="https://zhuji.jb51.net/uploads/img/202305/371cd3dcf874c70f6eb44c512c2b9fbe.jpg">

八. 附录

这是kube-flannel.yml文件的内容，已经将无法访问的地址(quay.io)全部改为国内可以访问的地址(quay-mirror.qiniu.com)。我们新建一个kube-flannel.yml文件，复制粘贴该内容即可。
