nfs

Introduction

This cheat sheet provides a quick reference for some common NFS (Network File System) commands and concepts. NFS is a distributed file system protocol that allows a user on a client computer to access files over a network as if they were on the local disk.

`NFS` Concepts

Exporting Directories

To share directories from the server to NFS clients, you need to export them.

Edit the NFS exports configuration file:
```
sudo nano /etc/exports
```
Export a directory to a specific client:
```
/path/to/shared/dir client_ip(options)
```

NFS Server Commands

Managing the NFS server on the server-side involves starting, stopping, and checking its status.

Start the NFS server:
```
sudo service nfs-kernel-server start
```
Stop the NFS server:
```
sudo service nfs-kernel-server stop
```
Check the status of the NFS server:
```
sudo service nfs-kernel-server status
```

NFS Client Commands

On the client-side, you can mount and unmount NFS shares.

Mount an NFS share:

sudo mount server_ip:/shared_dir /mnt/local_mount_point

Unmount an NFS share:
```
sudo umount /mnt/local_mount_point
```

Viewing NFS Mounts

You can view mounted NFS shares on a client.

List mounted NFS shares on the client:
```
mount | grep nfs
```

NFS Security

NFS allows you to control access to shared directories using export options.

Export a directory with read-only access:
```
/path/to/shared/dir client_ip(ro)
```
Export a directory with read-write access:
```
/path/to/shared/dir client_ip(rw)
```

`NFS` Command-Line

Edit the NFS exports configuration file:
```
sudo nano /etc/exports
```
Start the NFS server:
```
sudo service nfs-kernel-server start
```
Stop the NFS server:
```
sudo service nfs-kernel-server stop
```
Check the status of the NFS server:
```
sudo service nfs-kernel-server status
```

Mount an NFS share:

sudo mount server_ip:/shared_dir /mnt/local_mount_point

Unmount an NFS share:
```
sudo umount /mnt/local_mount_point
```
List mounted NFS shares on the client:
```
mount | grep nfs
```

Conclusion

This cheat sheet covers some common NFS (Network File System) commands and concepts. NFS is a powerful protocol for sharing files and directories across a network, making it valuable for network file sharing and storage solutions; refer to the official NFS documentation for more in-depth information and advanced usage.
