服务端安装

创建挂载目录

mkdir -p /data/volumes/develop
mkdir -p /data/volumes/product
chmod -R 777 /data/volumes

#安装软件

yum install nfs-utils
yum install rpcbind

#配置开机启动

chkconfig nfs on
chkconfig rpcbind on

#启动相关服务

service rpcbind start
service nfs start

开放防火墙端口

firewall-cmd --add-port=2049/tcp --permanent
firewall-cmd --reload
firewall-cmd --list-ports

添加系统设置

vim /etc/exports
# 添加系统配置，添加内容如下：
# 设置输出目录只读：ro，设置输出目录读写：rw
# 客户端是指网络中可以访问这个NFS输出目录的计算机：
#    指定ip地址的主机：192.168.0.200
#    指定子网中的所有主机：192.168.0.0/24 192.168.0.0/255.255.255.0
#    指定域名的主机：david.bsmart.cn
#    指定域中的所有主机：*.bsmart.cn
#    所有主机：*
##########
/data/volumes *(rw,async,no_root_squash,no_subtree_check)
##########

刷新配置

exportfs -a

验证配置内容

exportfs -rv

#重启服务

systemctl restart nfs & systemctl restart rpcbind

#设置开机自启动

systemctl enable nfs & systemctl enable rpcbind

增加NFS存储类，以方便动态扩展PV

创建 rbac.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: nfs-client-provisioner
  namespace: default        #根据实际环境设定namespace,下面类同
---
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: nfs-client-provisioner-runner
rules:
  - apiGroups: [""]
    resources: ["persistentvolumes"]
    verbs: ["get", "list", "watch", "create", "delete"]
  - apiGroups: [""]
    resources: ["persistentvolumeclaims"]
    verbs: ["get", "list", "watch", "update"]
  - apiGroups: ["storage.k8s.io"]
    resources: ["storageclasses"]
    verbs: ["get", "list", "watch"]
  - apiGroups: [""]
    resources: ["events"]
    verbs: ["create", "update", "patch"]
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: run-nfs-client-provisioner
subjects:
  - kind: ServiceAccount
    name: nfs-client-provisioner
    namespace: default
roleRef:
  kind: ClusterRole
  name: nfs-client-provisioner-runner
  apiGroup: rbac.authorization.k8s.io
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: leader-locking-nfs-client-provisioner
  namespace: default
rules:
  - apiGroups: [""]
    resources: ["endpoints"]
    verbs: ["get", "list", "watch", "create", "update", "patch"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: leader-locking-nfs-client-provisioner
subjects:
  - kind: ServiceAccount
    name: nfs-client-provisioner
    namespace: default
roleRef:
  kind: Role
  name: leader-locking-nfs-client-provisioner
  apiGroup: rbac.authorization.k8s.io

创建NFS资源的StorageClass，nfs-storage.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: managed-nfs-storage
provisioner: qgg-nfs-storage #这里的名称要和provisioner配置文件中的环境变量PROVISIONER_NAME保持一致parameters:  archiveOnDelete: "false"

创建NFS provisioner，nfs-provisioner.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nfs-client-provisioner
  labels:
    app: nfs-client-provisioner
  namespace: default  #与RBAC文件中的namespace保持一致
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nfs-client-provisioner
  strategy:
    type: Recreate
  selector:
    matchLabels:
      app: nfs-client-provisioner
  template:
    metadata:
      labels:
        app: nfs-client-provisioner
    spec:
      serviceAccountName: nfs-client-provisioner
      containers:
        - name: nfs-client-provisioner
          image: quay.io/external_storage/nfs-client-provisioner:latest
          volumeMounts:
            - name: nfs-client-root
              mountPath: /persistentvolumes
          env:
            - name: PROVISIONER_NAME
              value: qgg-nfs-storage  #provisioner名称,请确保该名称与 nfs-StorageClass.yaml文件中的provisioner名称保持一致
            - name: NFS_SERVER
              value: 172.16.20.58   #NFS Server IP地址
            - name: NFS_PATH  
              value: /data/volumes    #NFS挂载卷
      volumes:
        - name: nfs-client-root
          nfs:
            server: 172.16.20.58  #NFS Server IP地址
            path: /data/volumes     #NFS 挂载卷

依次创建yaml

kubectl create -f rbac.yaml
kubectl create -f nfs-storage.yaml
kubectl create -f nfs-provisioner.yaml

查看存储类

kubectl get sc
[root@master ~]# kubectl get pods
NAME                                      READY   STATUS    RESTARTS   AGE
nfs-client-provisioner-74489dc4d4-z2dmm   1/1     Running   0          43m

创建pvc一直pending问题解决

如果是通过yaml文件部署kube-apiserver的,在kube-apiserver.yaml中添加- --feature-gates=RemoveSelfLink=false参数。通过命令可以查找kube-apiserver.yaml文件位置

find / -name kube-apiserver.yaml 
vi /etc/kubernetes/manifests/kube-apiserver.yaml 
# 添加- --feature-gates=RemoveSelfLink=false参数
systemctl daemon-reload
