Network file system (NFS) set up in Linux (CentOS/Red Hat)

You are most welcome to this post.

Really thanks to you for your interest in this topics. :)

Now in this post, we’ll discuss and enjoy the NFS. NFS stands for Network File System. It is a server client protocol and it is used for sharing files between UNIX/LINUX to UNIX/LINUM system. Also you can mount a remote share locally through the NFS. After doing so, you can be able to access files which is located in the remote.

Network file system (NFS) set up in Linux (CentOS/Red Hat)

 

At first just have a look at the Reference Table:

We’ll use this Packages: nfs-utils, nfs-utils-lib

Daemon: nfs-server, rpcbind,

 

IP of NFS Server: 172.25.11.200+X (Virtual Machine)

IP of NFS Client: 172.25.11.100+X (Desktop Machine)

 

Step 01: Query and Package Install

[root@serverX ~]# rpm -qa | grep nfs-utils

[root@serverX ~]# yum install nfs-utils nfs-utils-lib -y

 

Step 02: Service Restart and enable

[root@serverX ~]# systemctl enable rpcbind.service

[root@serverX ~]# systemctl enable nfs-server.service

 

(Optional) systemctl enable nfs-idmap.service

 

[root@serverX ~]# systemctl start rpcbind.service

[root@serverX ~]# systemctl start nfs-server.service

 

(Optional)systemctl start nfs-idmap.service

 

SELinux Disable:

[root@serverX ~]# setenforce 0

 

Allow NFS Service in Firewall:

 

[root@serverX ~]# systemctl restart firewalld.service

[root@serverX ~]# systemctl enable firewalld.service

[root@serverX ~]# firewall-cmd –permanent –add-service=nfs

[root@serverX ~]# firewall-cmd –reload

 

Step 03: Create a shared directory

[root@serverX ~]# mkdir /nfsshare -p

[root@serverX ~]# cd /nfsshare

[root@serverX nfsshare]# ls

[root@serverX nfsshare]# mkdir download documents software project office

[root@serverX nfsshare]# ls

documents download office project software

[root@serverX nfsshare]# cd documents/

[root@serverX documents]# ls

[root@serverX documents]# touch doc{1..10}

[root@serverX documents]# cd ..

[root@serverX nfsshare]# cd download/

[root@serverX download]# touch file1 file2 file3

[root@serverX download]# cd ..

[root@serverX nfsshare]# cd office

[root@serverX office]# touch job cv profile

[root@serverX office]# cd ..

[root@serverX nfsshare]# cd project/

[root@serverX project]# touch project{1..5}

[root@serverX project]# cd ..

[root@serverX nfsshare]# cd software/

[root@serverX software]# touch office.exe vlc.exe skype.exe

[root@serverX software]# cd ..

[root@serverX nfsshare]#

 

Step 04: Export shared directory on NFS Server:

[root@serverX ~]# vim /etc/exports

 

/nfsshare/software     172.25.11.0/24(rw,sync,no_root_squash)

/nfsshare/project       172.25.11.0/24(ro,sync,no_root_squash)

/nfsshare/download     *(ro,sync,no_root_squash)

/nfsshare/documents     172.25.11.100+X(rw,sync,no_root_squash)

/nfsshare/office       *.example.com(rw,sync,no_root_squash)

 

Note:

=> /var/nfshare – shared directory

=> 172.25.11.0/24 – IP address range of clients

=> rw – Writable permission to shared folder

=> sync – Synchronize shared directory

=> no_root_squash – Enable root privilege

=> no_all_squash – Enable user’s authority

 

Step 05: Restart the NFS service and verify:

[root@serverX ~]# systemctl restart nfs-server

[root@serverX ~]# exportfs -ra

[root@serverX ~]# showmount -e localhost

 

Client Side Confiugration:

Step 06: Install NFS packages in your client system

[root@desktopX ~]# yum install nfs-utils nfs-utils-lib

 

Step 07: Service Restart and enable

[root@desktopX ~]# systemctl enable rpcbind.service

[root@desktopX ~]# systemctl enable nfs-server.service

 

(Optional)

systemctl enable nfs-idmap.service

 

[root@desktopX ~]# systemctl start rpcbind.service

[root@desktopX ~]# systemctl start nfs-server.service

 

(Optional) systemctl start nfs-idmap.service

 

Step 08: View NFS Share on NFS Server

[root@desktopX ~]# showmount -e 172.25.11.200+X     ; X is your NFS Server IP

 

Export list for 172.25.11.X:

/nfsshare/download *

/nfsshare/office   *.example.com

/nfsshare/project   172.25.11.0/24

/nfsshare/software 172.25.11.0/24

/nfsshare/documents 172.25.11.100+X       ; X = Specific an IP address

 

Step 09: Mount NFS shares On clients

[root@desktopX ~]# mkdir /nfsdataY       ; Y is your batch no

[root@desktopX ~]# mount -t nfs 172.25.11.200+X:/nfsshare/project /nfsdataY

[root@desktopX ~]# cd /nfsdataY

[root@desktopX nfsdataY]# ls

[root@desktopX nfsdataY]# df -HT

[root@desktopX nfsdataY]# touch newproject

[root@desktopX nfsdataY]# cd

[root@desktopX ~]# umount /nfsdataY

 

[root@desktopX ~]# mount -t nfs 172.25.11.200+X:/nfsshare/software /nfsdataY

[root@desktopX ~]# cd /nfsdataY

[root@desktopX nfsdataY]# ls

[root@desktopX nfsdataY]# df -HT

[root@desktopX nfsdataY]# touch newsoft

[root@desktopX nfsdataY]# cd

[root@desktopX ~]# umount /nfsdata

 

Step 10: Mount NFS shares On clients

[root@desktopX ~]# vim /etc/fstab

 

172.25.11.200+X:/nfsshare/project /nfsdata nfs defaults 0 0

 

[root@desktopX ~]# mount -a

[root@desktopX ~]# mount
