前置環境配置-部署默認存儲類型
這里使用nfs
#所有節點安裝
yum install -y nfs-utils
# 在master節點執行以下命令
echo "/nfs/data/ *(insecure,rw,sync,no_root_squash)" > /etc/exports
# 執行以下命令，啟動 nfs 服務;創建共享目錄
mkdir -p /nfs/data
# 在master執行
systemctl enable rpcbind
systemctl enable nfs-server
systemctl start rpcbind
systemctl start nfs-server
# 使配置生效
exportfs -r
#檢查配置是否生效
exportfs
#在從節點執行(選做)
showmount -e 192.168.8.11
mkdir -p /nfs/data
mount -t nfs 192.168.8.11:/nfs/data /nfs/data
配置存儲，注意修改nfs服務的IP
#創建sc.yaml，
kubectl apply -f sc.yaml##確認配置是否生效
kubectl get sc
sc.yaml
## 創建了一個存儲類

部署kubesphere
#下載安裝配置文件
wget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/kubesphere-installer.yaml
wget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/cluster-configuration.yaml
#無需修改，直接apply
kubectl apply -f kubesphere-installer.yaml#需要修改一些配置 啟用所需插件，修改網絡策略等
kubectl apply -f cluster-configuration.yaml#查看kubesphere安裝狀態
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f#等待安裝完成即可，過程有點漫長
#查看一下，是否有pod非running狀態
kubectl get pod -A
#查看一下pod，未running的原因
kubectl describe pod -n kubesphere-monitoring-system prometheus-k8s-0
kubectl describe pod -n kubesphere-monitoring-system prometheus-k8s-1
kubectl describe pod -n kubesphere-system openpitrix-import-job-8qczq
#解決上面的問題
kubectl -n kubesphere-monitoring-system create secret generic kube-etcd-client-certs --from-file=etcd-client-ca.crt=/etc/kubernetes/pki/etcd/ca.crt --from-file=etcd-client.crt=/etc/kubernetes/pki/apiserver-etcd-client.crt --from-file=etcd-client.key=/etc/kubernetes/pki/apiserver-etcd-client.key
等會再看看pod狀態。
