一、安装前环境准备
# kubesphere官网：https://kubesphere.io/zh/docs/v3.4/introduction/what-is-kubesphere/ # 1.kubenetes版本查看 [root@master kubesphere]# kubectl get nodes NAME STATUS ROLES AGE VERSION master Ready control-plane 106m v1.26.0 node1 Ready work 103m v1.26.0 # 2.kubesphere安装前环境准备 # https://kubesphere.io/zh/docs/v3.4/installing-on-kubernetes/introduction/prerequisites/ Centos 7.9 cpu内存：4核8G 硬盘：50G 依赖项：yum install -y socat、conntrack、ebtables、ipset # 2.集群中创建默认StorageClass # 默认没有，可以自建 创建 StorageClass 设置默认 StorageClass
# 创建storageclass最后
[root@master kubesphere]# cat sc.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer
# 设置为默认StorageClass
ubectl patch storageclass local-storage -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
# 执行查看
[root@master kubesphere]# kubectl get sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
local-storage (default) kubernetes.io/no-provisioner Delete WaitForFirstConsumer false 54m
PS:上面创建的storageclass 确实可以成功安装kubesphere，但是local-storage配合pvc无法动态创建pv。因此，创建storageclass 也可以使用nfs-storageclass
二、安装kubesphere
# 1.如果配置要求达到8核16G，可以把插件都启用安装上，没有的话就最小化安装 # 执行命令安装 kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.4.1/kubesphere-installer.yaml kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.4.1/cluster-configuration.yaml # 2.检查安装日志，上面命令执行完成后，等待10分钟左右可以看到
Start installing monitoring
Start installing multicluster
Start installing openpitrix
Start installing network

# 3.使用 kubectl get pod --all-namespaces 查看所有 Pod 在 KubeSphere 相关的命名空间是否正常运行。如果是正常运行，请通过以下命令来检查控制台的端口（默认为 30880）：
[root@master kubesphere]# kubectl get pod --all-namespaces NAMESPACE NAME READY STATUS RESTARTS AGE kube-system calico-kube-controllers-6d6dc86d84-dfdsv 1/1 Running 0 127m kube-system calico-node-r6zrj 1/1 Running 0 127m kube-system calico-node-xh8dv 1/1 Running 1 (125m ago) 127m kube-system calico-typha-57cbf5b54d-4zc9r 1/1 Running 0 127m kube-system coredns-567c556887-j9jfb 1/1 Running 0 133m kube-system coredns-567c556887-mv57p 1/1 Running 0 133m kube-system etcd-master 1/1 Running 0 133m kube-system kube-apiserver-master 1/1 Running 0 133m kube-system kube-controller-manager-master 1/1 Running 0 133m kube-system kube-proxy-4lrj6 1/1 Running 0 133m kube-system kube-proxy-pdwzp 1/1 Running 0 130m kube-system kube-scheduler-master 1/1 Running 0 133m kube-system snapshot-controller-0 1/1 Running 0 42m kubesphere-controls-system default-http-backend-864f4f5c6b-s6s92 1/1 Running 1 (40m ago) 41m kubesphere-controls-system kubectl-admin-c6988866d-ghstw 1/1 Running 0 34m kubesphere-monitoring-system alertmanager-main-0 2/2 Running 0 38m kubesphere-monitoring-system kube-state-metrics-5f77fc8f6d-7pvbz 3/3 Running 0 38m kubesphere-monitoring-system node-exporter-7nwsc 2/2 Running 0 38m kubesphere-monitoring-system node-exporter-kf5cj 2/2 Running 0 38m kubesphere-monitoring-system notification-manager-deployment-f86fdf45d-m5gj9 2/2 Running 0 37m kubesphere-monitoring-system notification-manager-operator-7b8dcfd75c-bpm6c 2/2 Running 0 37m kubesphere-monitoring-system prometheus-k8s-0 0/2 Pending 0 38m kubesphere-monitoring-system prometheus-operator-845b8fb9df-nxhpd 2/2 Running 0 38m kubesphere-system ks-apiserver-756b474857-47jjd 1/1 Running 0 41m kubesphere-system ks-console-876f69ff4-47rgn 1/1 Running 0 41m kubesphere-system ks-controller-manager-64d7d5dc77-95ln2 1/1 Running 0 41m kubesphere-system ks-installer-7fc5675448-8wphm 1/1 Running 0 43m [root@master kubesphere]# kubectl get svc/ks-console -n kubesphere-system NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE ks-console NodePort 10.96.165.196 <none> 80:30880/TCP 43m
4.确保在安全组中打开了 30880 端口，通过 NodePort (IP:30880) 使用默认帐户和密码 (admin/P@88w0rd) 访问 Web 控制台

三、启动插件
# 插件占用资源 https://kubesphere.io/zh/docs/v3.4/pluggable-components/overview/ # 启动日志插件 [root@master kubesphere]# vim cluster-configuration.yaml logging: enabled: true # false改true [root@master kubesphere]# kubectl apply -f cluster-configuration.yaml clusterconfiguration.installer.kubesphere.io/ks-installer configured [root@master kubesphere]# kubectl get pods --all-namespaces | grep log kubesphere-logging-system fluent-bit-77s4z 0/1 ContainerCreating 0 31s kubesphere-logging-system fluent-bit-b5zlk 0/1 ContainerCreating 0 31s kubesphere-logging-system fluentbit-operator-67898f4dd8-lxnd5 1/1 Running 0 2m14s kubesphere-logging-system opensearch-cluster-data-0 0/1 Pending 0 2m31s kubesphere-logging-system opensearch-cluster-data-1 0/1 Pending 0 2m30s kubesphere-logging-system opensearch-cluster-master-0 0/1 Pending 0 2m32s
