二：部署etcd 服务
2.1 设置关于签名证书
下载：
wget https://github.com/cloudflare/cfssl/releases/download/v1.6.1/cfssl_1.6.2_linux_amd64
wget https://github.com/cloudflare/cfssl/releases/download/v1.6.1/cfssljson_1.6.2_linux_amd64
wget https://github.com/cloudflare/cfssl/releases/download/v1.6.1/cfssl-certinfo_1.6.1_linux_amd64
mv cfssl_1.6.1_linux_amd64 /usr/bin/cfssl
mv cfssljson_1.6.1_linux_amd64 /usr/bin/cfssljson
mv cfssl-certinfo_1.6.1_linux_amd64 /usr/bin/cfssl-certinfo
chmod +x /usr/bin/cfssl*
mkdir -p ~/TLS/etcd,k8s
cd ~/TLS/etcd
自签CA：
cat > ca-config.json << EOF
"signing":
"default":
"expiry": "87600h"
,
"profiles":
"www":
"expiry": "87600h",

"key":
"algo": "rsa",

]
EOF
生成证书：
cfssl gencert -initca ca-csr.json | cfssljson -bare ca -
会生成ca.pem和ca-key.pem文件
#使用自签CA签发Etcd HTTPS证书
#创建证书申请文件：
cat > server-csr.json << EOF

#注：上述文件hosts字段中IP为所有etcd节点的集群内部通信IP，一个都不能少！为了方便后期扩容可以多写几个预留的IP。
#生成证书：
cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=www server-csr.json | cfssljson -bare server
#会生成server.pem和server-key.pem文件。
1. Etcd 的概念：
Etcd 是一个分布式键值存储系统，Kubernetes使用Etcd进行数据存储，所以先准备一个Etcd数据库，为解决Etcd单点故障，应采用集群方式部署，这里使用3台组建集群，可容忍1台机器故障，当然，你也可以使用5台组建集群，可容忍2台机器故障。
下载地址： https://github.com/etcd-io/etcd/releases
以下在节点flyfish81上操作，为简化操作，待会将节点flyfish81生成的所有
文件拷贝到节点flyfish82和节点flyfish83.
2. 安装配置etcd
mkdir /opt/etcd/bin,cfg,ssl -p
tar zxvf etcd-v3.5.5-linux-amd64.tar.gz
mv etcd-v3.5.5-linux-amd64/etcd,etcdctl /opt/etcd/bin/
#flyfish81 etcd 配置文件

2.2 安装etcd
#拷贝刚才生成的证书

5. 同步所有主机
scp -r /opt/etcd/ root@172.16.10.82:/opt/

scp /usr/lib/systemd/system/etcd.service root@172.16.10.82:/usr/lib/systemd/system/

#拷贝刚才生成的证书
#把刚才生成的证书拷贝到配置文件中的路径：
cp ~/TLS/k8s/ca*pem ~/TLS/k8s/server*pem /opt/kubernetes/ssl/
#启用 TLS Bootstrapping 机制
TLS Bootstraping：Master apiserver启用TLS认证后，Node节点kubelet和
kube-proxy要与kube-apiserver进行通信，必须使用CA签发的有效证书才可以，
当Node节点很多时，这种客户端证书颁发需要大量工作，同样也会增加集群扩展复杂度。
为了简化流程，Kubernetes引入了TLS bootstraping机制来自动颁发客户端证书，
kubelet会以一个低权限用户自动向apiserver申请证书，
kubelet的证书由apiserver动态签署。
所以强烈建议在Node上使用这种方式，目前主要用于kubelet，kube-proxy
还是由我们统一颁发一个证书。
创建上述配置文件中token文件：

cp kubelet kube-proxy /opt/kubernetes/bin # 本地拷贝

五：部署calico网络
网络组件有很多种，只需要部署其中一个即可，推荐Calico。
Calico是一个纯三层的数据中心网络方案，Calico支持广泛的平台，包括Kubernetes、OpenStack等。
Calico 在每一个计算节点利用 Linux Kernel 实现了一个高效的虚拟路由器（ vRouter） 来负责数据转发，而每个 vRouter 通过 BGP 协议负责把自己上运行的 workload 的路由信息向整个 Calico 网络内传播。
此外，Calico 项目还实现了 Kubernetes 网络策略，提供ACL功能。
1.下载Calico
wget https://docs.projectcalico.org/manifests/calico.yaml --no-check-certificate
vim calico.yaml
...
- name: CALICO_IPV4POOL_CIDR
value: "10.244.0.0/16"
...
cat calico.yaml |grep image
docker pull docker.io/calico/cni:v3.24.5
docker pull docker.io/calico/node:v3.24.5
docker pull docker.io/calico/kube-controllers:v3.24.5
kubectl apply -f calico.yaml
kubectl get pod -n kube-system
kubectl get node
授权apiserver访问kubelet
应用场景：例如kubectl logs
cat > apiserver-to-kubelet-rbac.yaml << EOF
apiVersion: rbac.authorization.k8s.io/v1

- apiGroup: rbac.authorization.k8s.io
kind: User
name: kubernetes
EOF
kubectl apply -f apiserver-to-kubelet-rbac.yaml
六：新增加一个worker node
6.1 同步配置文件
1. 拷贝已部署好的Node相关文件到新节点
在Master节点将Worker Node涉及文件拷贝到新节点172.16.10.82/83
scp -r /opt/kubernetes root@172.16.10.82:/opt/
scp /opt/kubernetes/ssl/ca.pem root@172.16.10.82:/opt/kubernetes/ssl
scp -r /usr/lib/systemd/system/kubelet,kube-proxy.service root@172.16.10.82:/usr/lib/systemd/system
scp -r /opt/kubernetes root@172.16.10.83:/opt/
scp /opt/kubernetes/ssl/ca.pem root@172.16.10.83:/opt/kubernetes/ssl
scp -r /usr/lib/systemd/system/kubelet,kube-proxy.service root@172.16.10.83:/usr/lib/systemd/system
删除kubelet证书和kubeconfig文件
rm -rf /opt/kubernetes/cfg/kubelet.kubeconfig
rm -rf /opt/kubernetes/ssl/kubelet*
rm -rf /opt/kubernetes/logs/*
注：这几个文件是证书申请审批后自动生成的，每个Node不同，必须删除
修改主机名 [改节点的主机名]
flyfish82:
vi /opt/kubernetes/cfg/kubelet.conf
--hostname-override=flyfish82
vi /opt/kubernetes/cfg/kube-proxy-config.yml
hostnameOverride: flyfish82
修改主机名 [改节点的主机名]
flyfish83:
vi /opt/kubernetes/cfg/kubelet.conf
--hostname-override=flyfish83
vi /opt/kubernetes/cfg/kube-proxy-config.yml
hostnameOverride: flyfish83
启动并设置开机启动
systemctl daemon-reload
systemctl start kubelet kube-proxy
systemctl enable kubelet kube-proxy
在Master上批准新Node kubelet证书申请
kubectl get csr
# 授权请求
kubectl certificate approve node-csr-95-n0_MYOJSE4w1LVdyytVBuqaJ90mccZJArob1wlnU
kubectl certificate approve node-csr-LRzjATYqgofqoo6rGoCk_3X4OEYSjdunOvzpninfLLg
