Mount Command Nfs Driver At Home
File on NFS mount fails with Invalid Argument. Getting StartedWindows 10 is my daily driver at home so I need a way to use some Linux. This tutorial describes the process of setting up at NFS mount on CentOS7 using two servers to act as the NFS host and client, as well as give an example of typical usage. NFS is a UNIX based technology but can be used by most of the operating systems like Linux, Ubuntu, Debian, Kali, Mint, Fedora, CentOS, RedHat and Windows operating systems Windows 7, Windows 8, Windows 10, Windows Server 2008, Windows Server 2012, Windows Server. Network File System or NFS is a network-based filesystem protocol which is mainly used to share files and folders over the network.
2 Node ( Cloud Server or Dedicated Server) running CentOS 7.btrfs filesystem resize +10g / Resize / of +10g. This is required to ensure reliable mounts. Ensure that each Windows NFSv3 client uses hard mounts by specifying the -o mtypehard option. Windows NFSv3 clients can now mount exports on the storage system. Enable Windows NFSv3 client support: vserver nfs modify -vserver vservername -v3-ms-dos-client enabled.
We will continue in our tutorial however assuming root access, and thus there is no need to change permissions.To be able to share this repository, we must create an exports file for NFS to use:This file provides information for NFS concerning the configuration of what is being shared via NFS and will have the following format. This can be done using sudo chown nobody:nogroup /sharednfs. However, for the case that you want to use a directory only for sharing (for example, not /home but something like /var/fornfsonly), then you should change the ownership of the repository. Remember that all commands should be executed as the root user.With the necessary NFS packages installed, use the following commands to enable and start the necessary services on boot:For our repository to be shared using NFS, we will create /sharednfss on the NFS host with this command:Since we are using sudo, this sharing directory is owned by the root user. We begin by installing the nfs-utils package. In the file we opened, make sure that the SELINUX= line is set to disabled as shown.After editing the SELinux configuration file, you must restart the servers to apply the new settings with the following command:Now we are ready to setup our NFS host server, so all actions in this section should be executed on the NFS server.
Reload the new exports file and restart the NFS service with:Systemctl restart nfs-server Setting Up Your Client ServerAfter setting up the host, proceed with the setup of your second CentOS 7 server that will be your client. The last option,no_root_squash, is used to allow root access in the case that a shared repository is owned by root, as traditionally NFS restricts client root access to host root-owned repositories.These changes allow the repositories specified in the exports file to be shared after the exports file is loaded. No_subtree_check, much like it sounds, prevents subtree checking, which is essentially the host performing a check to see if a file is still available. Sync directs NFS to, before replying to clients, store any changes that were made in the shared repository to the disk, thus ensuring file consistency. The first option, rw, allows clients repository read and write access. In the exports file we just opened, type the following line before saving and closing the file:/sharednfs client(rw,sync,no_root_squash,no_subtree_check)For our shared repository, we used the following options: rw,sync,no_root_squash,no_subtree_check.
This type of setup provides many advantages ranging from central management to space optimization. On your NFS server, navigate to /sharednfs and create a file:Next, on the client server, go to the mounted directory and check “hello.txt” is there as it should be:Now that you have completed this guide, you have a basic overview of how NFS mounting works in a host and client network environment. The man page for NFS (accessed by typing man nfs in the prompt or found online) provides a multitude of options for the actual mount-on-boot process that can be set within this file.Nfs-server:/sharednfs nfs nfs defaults 0 0 Testing Your NFS Mount SetupWe can verify that the setup is working as it should with a simple test. To begin, open the file:With the fstab file open, add this line to the end of the file, save, and close. To check that the shared directory is indeed mounted, use the following command, which shows the shared repositories and sharing settings line by line:So we don’t have to mount this directory to be shared manually each time we start our client server, we can modify the fstab file to mount automatically on boot. This directory should also be accessible from its mount point /mnt/sharednfs on the client server, which has the IP address 10.10.0.134.
If this guide for setting up NFS on CentOS 7 was useful to you, go ahead and share it with your friends. Aside from protocol, NFS does offer an enhanced flexibility in how repositories are shared and with whom, which does provide some security. This means you can take further steps to enhance security if the environment calls for it.
