一.k8s环境搭建

部署k8s

二.部署nfs

1.master节点安装nfs服务端

 yum -y install rpcbind nfs-utils
 systemctl start rpcbind.service
 systemctl start nfs.service

2.创建需要挂载的目录

mkdir -pv /data/volumes

chown -R nfsnobody.nfsnobody /data/volumes

3.配置/etc/exports文件

vim /etc/exports

/data/volumes 192.168.22.45(insecure,rw,async,no_root_squash)

#使配置生效
exportfs -rv
# 查看配置
exportfs

4.node节点安装nfs客户端

yum -y install nfs-utils rpcbind
systemctl start rpcbind.service

三.helm部署storageclass(动态存储)

1.安装helm

wget https://get.helm.sh/helm-v3.2.4-linux-amd64.tar.gz

tar -zxvf helm-v3.2.4-linux-amd64.tar.gz

mv linux-amd64/helm /usr/local/bin/helm

2.helm安装nfs-provisioner

helm repo add azure http://mirror.azure.cn/kubernetes/charts/

helm install nfs-client azure/nfs-client-provisioner \
--set nfs.server=192.168.1.33 \
--set nfs.path=/data/volumes \
--set storageClass.name=glusterfs \
--set storageClass.defaultClass=true

3.查看

kubectl get sc

kubectl get pod 

4.创建测试文件测试

# 配置
cat <<EOF >  pvc-test.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-test
spec:
  storageClassName: "nfs-storage"
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Mi
EOF

kubectl apply -f pvc-test.yaml

# 查看
kubectl get pvc

状态是Bound为成功，Pending则为异常

如果异常，编辑yaml文件，加入 - --feature-gates=RemoveSelfLink=false

vim /etc/kubernetes/manifests/kube-apiserver.yaml

四.安装kubesphere

1.打开github中kubesphere项目，下载yaml文件到master节点

kubectl apply -f kubesphere-installer.yaml

2.编辑cluster-configuration.yaml文件，将里面devops等组件开启(将false改成true)

vim cluster-configuration.yaml

kubectl apply -f cluster-configuration.yaml

3.查看日志，看安装任务是否成功

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f

五.登陆kubesphere(http://192.168.1.33:30880)
