How to Configure NFS File Sharing Server on CentOS 7




NFS (Network File System) is a distributed network file sharing system protocol. It is provides to share files and folders between Linux distributions over the network.

This article describes How to Configure NFS Server on CentOS7.

NFS Server Configuration:

Step 1. Package installation: NFS Server package is available in CentOS7 base repository. Run the following command to install NFS Server packages:

[root@lc-nfsserver ~]# yum install nfs-utils
Loaded plugins: fastestmirror
………………..
Installed:
  nfs-utils.x86_64 1:1.3.0-0.65.el7

Dependency Installed:
  gssproxy.x86_64 0:0.7.0-26.el7          keyutils.x86_64 0:1.5.8-3.el7
………………..
  quota-nls.noarch 1:4.01-19.el7          rpcbind.x86_64 0:0.2.0-48.el7            tcp_wrappers.x86_64 0:7.6-77.el7

Complete!
[root@lc-nfsserver ~]#

Step 2. Start Services: Once the packages are installed start the services and enable to start on boot up:

[root@lc-nfsserver ~]# systemctl enable nfs-server rpcbind
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.
[root@lc-nfsserver ~]# systemctl start nfs-server rpcbind
[root@lc-nfsserver ~]#

Step 3. Configure NFS Share Directory: Create a new directory and allow full access to the NFS clients for NFS share configuration:

[root@lc-nfsserver ~]# mkdir /nfsshare
[root@lc-nfsserver ~]# chmod 777 /nfsshare/
[root@lc-nfsserver ~]# ls -ld /nfsshare/
drwxrwxrwx. 2 root root 6 Oct 21 05:19 /nfsshare/
[root@lc-nfsserver ~]#

Modify /etc/export configuration and put the following parameters. Change the address 192.168.43.24 according to environment and access restrictions:

[root@lc-nfsserver ~]# vi /etc/exports
/nfsshare       192.168.43.24(rw,sync,no_root_squash)

Save the file and export the shared directory for clients using following command:

[root@lc-nfsserver ~]# exportfs -r
[root@lc-nfsserver ~]#

Step 4. Firewall Configuration: Configure firewall to allow clients to access NFS Share:

[root@lc-nfsserver ~]# firewall-cmd --permanent --add-service={mountd,nfs,rpc-bind}
success
[root@lc-nfsserver ~]# firewall-cmd --reload
success
[root@lc-nfsserver ~]#

Done!!! NFS File Sharing Server is installed and configured successfully on CentOS7.
