基于github安装
选择对应的版本
这里选择 https://github.com/prometheus-operator/kube-prometheus/tree/release-0.11
下载修改为国内镜像源
image: quay.io 改为 quay.mirrors.ustc.edu.cn
image: k8s.gcr.io 改为 lank8s.cn

host文件修改
根据自己的情况配置
# Mac 下
sudo vim /etc/hosts

192.168.10.102 prometheus.wolfcode.cn
192.168.10.102 alertmanager.wolfcode.cn
# 先创建 setup 由于一些大资源，用apply会报错
kubectl create -f ./manifests/setup/
# 创建 其他
kubectl apply -f ./manifests/
# 查看
kubectl get all -n monitoring
# 成功的结果

具体操作
接下来访问我们定义的ingress
访问不了，由于我重新安装了 所以导致我的ingress-nginx没有部署---导致无法访问
ingress安装
最后的最后！！！！还是无法访问，但但但但是在终端通过
curl -H "host: alertmanager.wolfcode.cn" 192.168.10.102
又能打印出网页内容地址--问了一下 ai ，我把代理一关，困扰了我几天的问题终于解决啦
差一个grafana
kubectl edit networkPolicy -n monitoring grafana
内存不够 升级虚拟机内存重启 master报错了
重新安装
kubectl 查看命令是否正常
cd ~ 进入根目录
ll -a 查看是否存在.kube文件
rm -rf .kube/ 删除
systemctl restart docker 重启docker
systemctl restart kubelet 重启kubelet
kubeadm reset 重置
rm -rf /etc/cni/ 删除
# Step 2: 安装 kubeadm、kubelet、kubectl
yum install -y kubelet-1.23.6 kubeadm-1.23.6 kubectl-1.23.6
# 开启自启动
systemctl enable kubelet
#================在k8s-master上执行==============
# Step 1: 初始化master节点
kubeadm init \
--apiserver-advertise-address=192.168.10.100 \
--image-repository registry.aliyuncs.com/google_containers \
--kubernetes-version v1.23.6 \
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=10.244.0.0/16
# Step 2: 安装成功后，复制如下配置并执行
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
# Step 3: 查看是否初始化成功
kubectl get nodes
# 其他的参考 https://blog.csdn.net/weixin_41104307/article/details/137704714?spm=1001.2014.3001.5501
# ============分别在 k8s-node1 和 k8s-node2 执行================
# 下方命令可以在 k8s master 控制台初始化成功后复制 join 命令
# Step 1: 将node节点加入master
kubeadm join 192.168.10.100:6443 --token ce9w0v.48oku10ufudimvy3 \
--discovery-token-ca-cert-hash sha256:9ef74dbe219fb48ad72d776be94149b77616b8d9e52911c94fe689b01e47621c
其他节点的处理
kubeadm reset
sudo rm /etc/kubernetes/kubelet.conf
sudo rm /etc/kubernetes/pki/ca.crt
sudo netstat -tuln | grep 10250
reboot
kubeadm join 192.168.10.100:6443 --token 3prl7s.pplcxwsvql7i1s1d \
--discovery-token-ca-cert-hash sha256:9ef74dbe219fb48ad72d776be94149b77616b8d9e52911c94fe689b01e47621c
token过期解决方案【里面包含重新生成token】
主要是这个镜像
