Deploy NFS Server

Open ports TCP:111, UDP: 111, TCP:2049, UDP:2049

yum install nfs-utils -y

Now we will share the NFS directory over the network "the private subnet of kubernetes"

#you need to change "172.31.32.0/24" to your private subnet of the cluster or use *

vim /etc/exports

/ 172.31.32.0/24(rw,sync,no_root_squash)

#Create a backup directory for mysql & wordpress files "for volumes"

mkdir /{mysql,html}

chmod -R 755 /{mysql,html}

chown nfsnobody:nfsnobody /{mysql,html}

systemctl enable rpcbind

systemctl enable nfs-server

systemctl enable nfs-lock

systemctl enable nfs-idmap

systemctl start rpcbind

systemctl start nfs-server

systemctl start nfs-lock

systemctl start nfs-idmap
