nfs server安装&&k8s中部署nfs provisionernfs server安装&&

1.nfs server安装

1.1节点信息

192.168.0.203  

1.2.nfs server端

安装nfs服务
[root@MES-203 home]#yum -y install rpcbind nfs-utils

创建共享目录
[root@MES-203 home]# mkdir -p /home/nfsShare
[root@MES-203 home]#chmod 755 /home/nfsShare

配置nfs
[root@MES-203 home]# cat /etc/exports
/home/nfsShare/ 192.168.0.0/16(rw,no_root_squash)

使配置立即生效
  [root@MES-203 home]#exportfs -r

启动
 [root@MES-203 home]#systemctl start rpcbind
[root@MES-203 home]# systemctl start nfs
[root@MES-203 home]# systemctl enable nfs
[root@MES-203 home]# systemctl enable rpcbind

查看挂载点
showmount -e

1.3nfs client端测试

在192.168.0.204上测试

安装工具
[root@MES-204 ~]# yum -y install nfs-utils rpcbind

查看下服务端挂载点
[root@MES-204 ~]# showmount -e 192.168.0.203
Export list for 192.168.0.203:
/home/nfsShare 192.168.0.0/16

挂载
[root@MES-204 ~]# mkdir /root/nfstest
[root@MES-204 ~]# mount -t nfs 192.168.0.203:/home/nfsShare/ /root/nfstest

查看

取消挂载
[root@MES-204 ~]# umount /root/nfstest

2.k8s中部署nfs provisioner-用于storageClass

修改了NFS_SERVER 和path处

也修改了namespace为middleware

nfs server: 192.168.0.203
 path: /home/nfsShare

直接kubectl apply -f nfs.yaml
