集群删除与重建

1.删除集群

删除所有 node
删除所有 master

[root@master30 ~]# kubectl drain worker31.laoma.cloud --ignore-daemonsets --force
[root@master30 ~]# kubectl drain worker32.laoma.cloud --ignore-daemonsets --force
[root@master30 ~]# kubectl delete node worker31.laoma.cloud worker32.laoma.cloud

# 重置节点，注意执行位置
[root@worker31 ~]# kubeadm reset -f
[root@worker32 ~]# kubeadm reset -f

# 删除集群前获取集群配置
[root@master30 ~]# kubectl get cm kubeadm-config -n kube-system -o yaml > kubeadm.yml

# 修改kubeadm.yml内容如下：
[root@master30 ~]# vim kubeadm.yml
# 删除1-3和22-28行，效果如下
apiServer:
  timeoutForControlPlane: 4m0s
apiVersion: kubeadm.k8s.io/v1beta3
certificatesDir: /etc/kubernetes/pki
clusterName: kubernetes
controllerManager: {}
dns: {}
etcd:
  local:
    dataDir: /var/lib/etcd

scheduler: {}

[root@master30 ~]# kubectl delete node master30.laoma.cloud
[root@master30 ~]# kubeadm reset -f
[root@master30 ~]# rm -fr .kube/

2.重建集群

# 初始化集群
[root@master30 ~]# kubeadm init --config kubeadm.yml

# 也可以使用之前的命令
[root@master30 ~]# kubeadm init --kubernetes-version=v1.30.2 --pod-network-cidr=10.224.0.0/16

# 配置凭据
[root@master30 ~]# mkdir -p $HOME/.kube
[root@master30 ~]# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
[root@master30 ~]# sudo chown $(id -u):$(id -g) $HOME/.kube/config

# 配置网络
[root@master30 ~]# kubectl apply -f calico.yaml

# 加入集群
[root@worker31 ~]# kubeadm join 10.1.8.30:6443 --token ky95b9.sjg0fn21pdi1m0xz    --discovery-token-ca-cert-hash sha256xxxxxxx
[root@worker32 ~]# kubeadm join 10.1.8.30:6443 --token ky95b9.sjg0fn21pdi1m0xz    --discovery-token-ca-cert-hash sha256xxxxxxx

3.多集群配置

#查看配置文件里
certificate-authority-data 
client-certificate-data 
client-key-data

[root@master30 - 04:02:39]# cat .kube/config

将多集群配置模版multi-cluster-config.yaml里的证书和密钥修改成上面查到的，windows里改好再上传到master

【SpringBoot集成Redis】Spring Boot 集成 Redis 完整指南：从自动配置原理到序列化乱码彻底剖析

本文深入解析了SpringBoot集成Redis的核心机制，主要包含五个关键点：1）SpringBoot通过类路径扫描和条件注解实现Redis自动配置；2）生产环境应避免使用默认JDK序列化（存在可读性差、存储膨胀等问题），推荐JSON序列化方案；3）Redis默认序列化的"乱码"实质是Java序列化协议头；4）Redis基于TCP文本协议（RESP）通信，支持telnet等工
