[root@master wordpress]# kubectl describe pods -l app=mysql
MountVolume.SetUp failed for volume "kubernetes.io/nfs/690bf99f-ba01-11ea-bdcf-000c298e5202-pv0001" (spec.Name: "pv0001") pod "690bf99f-ba01-11ea-bdcf-000c298e5202" (UID: "690bf99f-ba01-11ea-bdcf-000c298e5202") with: mountfailed: exit status 32
Mounting command: mount            显示挂载失败

解决方法：

在node1和node2执行下面命令：
yum install -y nfs-utils-*
mkdir /data /code
vim /etc/exports
/data 10.0.0.0/24(rw,async,no_root_squash,no_all_squash)
/code 10.0.0.0/24(rw,async,no_root_squash,no_all_squash)

systemctl restart rpcbind
systemctl restart nfs
systemctl enable rpcbind
systemctl enable nfs
