NFS: ==== Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, allowing a user on a client computer to access files over a computer network much like local storage. NFS4 Configuration in RHEL 8 (CentOS 8): ================================== An acronym for Network File Share, NFS is a cross-platform client/server protocol that allows clients machines to access files shared by the NFS server over a network. Client systems can locally mount the filesystems from the NFS server and access files and directories as though they were locally mounted. In this guide, we will walk you through the installation and configuration of NFS Server on CentOS 8 / RHEL 8. Note: In CentOS 8 or RHEL 8 NFSv3 & v4 both are supported. NFSv3 allows safe asynchronous write and supports 64-bit file sizes & offset. Whereas NFSv4 works through OS firewall and support ACL (Access Control List) and doesn’t require rpcbind service dnf install nfs-utils -y systemctl start nfs-server.service systemctl enable nfs-server.service systemctl status nfs-server.service rpcinfo -p | grep nfs mkdir -p /mnt/nfs_shares/docs chown -R nobody: /mnt/nfs_shares/docs chmod -R 777 /mnt/nfs_shares/docs systemctl restart nfs-utils.service vim /etc/exports /mnt/nfs_shares/docs 192.168.2.103(rw,sync,no_all_squash,root_squash) cat /etc/exports /mnt/nfs_shares/docs 192.168.2.103(rw,sync,no_all_squash,root_squash) Let’s look at the meaning of the parameters used: rw – This stands for read/write. It grants read and write permissions to the NFS share. sync – The parameter requires the writing of the changes on the disk first before any other operation can be carried out. no_all_squash – This will map all the UIDs & GIDs from the client requests to identical UIDS and GIDs residing on the NFS server. root_squash – The attribute maps requests from the root user on the client-side to an anonymous UID / GID. To export the above created folder, use the exportfs command as shown: exportfs -arv exportfs -s firewall-cmd --permanent --add-service=nfs firewall-cmd --permanent --add-service=rpc-bind firewall-cmd --permanent --add-service=mountd firewall-cmd --reload Client Configuration: --------------------- dnf install nfs-utils nfs4-acl-tools -y showmount -e 192.168.2.102 mkdir -p /mnt/client_share mount -t nfs 192.168.2.102:/mnt/nfs_shares/docs /mnt/client_share mount | grep -i nfs 192.168.2.102:/mnt/nfs_shares/docs /mnt/client_share nfs defaults 0 0 Testing NFS Server & Client Setup: ---------------------------------- touch /mnt/nfs_shares/docs/server_nfs_file.txt ls -l /mnt/client_share/ touch /mnt/client_share/client_nfs_file.txt ls -l /mnt/nfs_shares/docs As you can see, you can easily create files on both the NFS server and client and share them seamlessly between the two systems as well as other client systems that have been configured to access the shares. And this brings us to the end of our tutorial today. In this guide, we showed you how to install and setup the NFS server and client system setup on CentOS 8 and RHEL 8. ==== My i5 10 Gen Laptop With 512 GB SSD & 8 GB DDR4: https://amzn.to/30amhRt ==== My DSLR Camera: https://amzn.to/36954Ml === Join this channel to get access to perks: null === Thanks for watching the video.
