NFS (Network File System) is basically developed for sharing of files and folders between Linux/Unix systems by Sun Microsystems in 1980. It allows you to mount your local file systems over a network and remote hosts to interact with them as they are mounted locally on the same system. With the help of NFS, we can set up file sharing between Unix to Linux system and Linux to Unix system.
Unfortunately, I have to go online to ad nfs files to make it work in the fedora33 server. I noticed you used init.d but redhat and its subsidiary ones all use the system.d in their configuration, so init.d might not work on a redhat/fedora/centos box!

On your NFS host, create a location on the filesystem to share with client computers. This could be a separate drive, a separate partition, or just a place on your server. To ensure that your storage can scale as needed, I recommend using LVM. Create the location with:
Network File System (NFS) provides a file sharing solution that lets you transfer files between computers running Windows Server and UNIX operating systems using the NFS protocol. This topic describe the steps you should follow to deploy NFS.
Integration with Resume Key Manager. The Resume Key Manager is a component that tracks file server and file system state and enables the Windows SMB and NFS protocol servers to fail over without disrupting clients or server applications that store their data on the file server. This improvement is a key component of the continuous availability capability of the file server running Windows Server 2012.
NFS supports a mixed environment of Windows-based and UNIX-based operating systems. The following deployment scenarios are examples of how you can deploy a continuously available Windows Server 2012 file server using NFS.
This scenario applies to organizations with heterogeneous environments that consist of both Windows and other operating systems, such as UNIX or Linux-based client computers. With this scenario, you can provide multi-protocol access to the same file share over both the SMB and NFS protocols. Typically, when you deploy a Windows file server in this scenario, you want to facilitate collaboration between users on Windows and UNIX-based computers. When a file share is configured, it is shared with both the SMB and NFS protocols, with Windows users accessing their files over the SMB protocol, and users on UNIX-based computers typically access their files over the NFS protocol.
NFS, or Network File System, is a distributed file system protocol that allows you to mount remote directories on your server. This lets you manage storage space in a different location and write to that space from multiple clients. NFS provides a relatively standard and performant way to access remote systems over a network and works well in situations where the shared resources must be accessed regularly.
Superusers can do anything anywhere on their system. However, NFS-mounted directories are not part of the system on which they are mounted, so by default, the NFS server refuses to perform operations that require superuser privileges. This default restriction means that superusers on the client cannot write files as root, reassign ownership, or perform any other superuser tasks on the NFS mount.
Sometimes, however, there are trusted users on the client system who need to perform these actions on the mounted file system but who have no need for superuser access on the host. You can configure the NFS server to allow this, although it introduces an element of risk, as such a user could gain root access to the entire host system.
Both of the shares we mounted appear at the bottom. Because they were mounted from the same file system, they show the same disk usage. To see how much space is actually being used under each mount point, use the disk usage command du and the path of the mount. The -s flag provides a summary of usage rather than displaying the usage for every file. The -h prints human-readable output.
If all goes well, as it should in most cases, the system will have /etc/nfs.conf with the defaults, and /etc/nfs.conf.d/local.conf with the changes. You can merge these two together manually, and then delete local.conf, or leave it as is. Just keep in mind that /etc/nfs.conf is not the whole story: always inspect /etc/nfs.conf.d as well, as it may contain files overriding the defaults.
One drawback of using a machine credential for mounts done by the root user is that you need a persistent secret (the /etc/krb5.keytab file) in the filesystem. Some sites may not allow such a persistent secret to be stored in the filesystem. An alternative is to use rpc.gssds -n option. From rpc.gssd(8):
NFS server is used to keep the read-only image of PXE boot file system. To install NFS server on the Linux distribution that supports yum, such as Fedora, CentOS, and RedHat, run the following command:
A Network File System (NFS) allows remote hosts to mount file systems over a network and interact with those file systems as though they are mounted locally. This enables you to consolidate resources onto centralized servers on the network.
The NFS server refers to the /etc/exports configuration file to determine whether the client is allowed to access any exported file systems. Once verified, all file and directory operations are available to the user.
Red Hat Enterprise Linux uses a combination of kernel-level support and service processes to provide NFS file sharing. All NFS versions rely on Remote Procedure Calls (RPC) between clients and servers. To share or mount NFS file systems, the following services work together depending on which version of NFS is implemented:
The format of the /etc/exports file is very precise, particularly in regards to use of the space character. Remember to always separate exported file systems from hosts and hosts from one another with a space character. However, there should be no other space characters in the file except on comment lines.
Each default for every exported file system must be explicitly overridden. For example, if the rw option is not specified, then the exported file system is shared as read-only. The following is a sample line from /etc/exports which overrides two default options:
The exportfs utility enables the root user to selectively export or unexport directories without restarting the NFS service. When given the proper options, the exportfs utility writes the exported file systems to /var/lib/nfs/xtab. Because the nfs-mountd service refers to the xtab file when deciding access privileges to a file system, changes to the list of exported file systems take effect immediately.
NFS (Network File System) is nothing but is basically developed for sharing of files and folders between Linux/Unix systems by Sun Microsystems in 1980. It permits you to mount your local classification system over a network using linux server and remote hosts to interact with them as they're mounted locally on the same system. With the assistance of NFS, we can set up file sharing between Unix to Linux system and Vise-Versa.
Network File System (NFS) provides a file-sharing solution that lets you transfer files between computers running Windows Server and other non-Windows operating systems such as Linux or UNIX using the NFS protocol.
Make sure that there is a uniform way in which user names and IDs (UIDs) are assigned to users across machines that might be sharing file systems using NFS. This can be achieved by using NIS, LDAP, or any uniform domain authentication mechanism in your domain.
The configuration is written to /etc/fstab and the specified file systems are mounted. When you start the YaST configuration client at a later time, it also reads the existing configuration from this file.
The prerequisite for importing file systems manually from an NFS server is a running RPC port mapper. The nfs service takes care to start it properly; thus, start it by entering systemctl start nfs as root. Then remote file systems can be mounted in the file system just like local partitions, using the mount:
The noauto option prevents the file system from being mounted automatically at start-up. If you want to mount the respective file system manually, it is possible to shorten the mount command specifying the mount point only:
NFS is one of the oldest protocols, developed in the 1980s. As such, NFS is usually sufficient if you want to share small files. However, when you want to transfer big files or many clients want to access data, an NFS server becomes a bottleneck and has a significant impact on the system performance. This is because files are quickly getting bigger, whereas the relative speed of Ethernet has not fully kept pace.
There is no single standard for Access Control Lists (ACLs) in Linux beyond the simple read, write, and execute (rwx) flags for user, group, and others (ugo). One option for finer control is the Draft POSIX ACLs, which were never formally standardized by POSIX. Another is the NFSv4 ACLs, which were designed to be part of the NFSv4 network file system with the goal of making something that provided reasonable compatibility between POSIX systems on Linux and WIN32 systems on Microsoft Windows.
When using NFSv4, Draft POSIX ACLs cannot be used even in emulation and NFSv4 ACLs need to be used directly; that means while setfacl can work on NFSv3, it cannot work on NFSv4. To allow NFSv4 ACLs to be used on an NFSv4 file system, SUSE Linux Enterprise Server provides the nfs4-acl-tools package, which contains the following: 2ff7e9595c
