Install and configure the NFS server in Ubuntu 14.04

Install and configure the NFS server in Ubuntu 14.04

(1) install the NFS server
1.1-install the Ubuntu nfs server:

Sudo apt-get install nfs-kernel-server

1.2-install the nfs client:

Sudo apt-get install nfs-common

(Nfs-commom is also installed when nsf-kernel-server is installed. If this software package is not installed, execute the command in 1.2)
1.3-set the shared file directory

Sudo mkdir /***/***

(2) Configure NFS
2.1-modify the configuration file/etc/exports

Add/home/USER/nfs * (rw, sync, no_root_squash, no_subtree_check) to the last line)
The preceding directory is shared with the nfs service client. * indicates that all network segments can be accessed (or specific IP addresses can be used)
Rw: The Client Connected to this directory has read and write permissions on the shared directory.
Sync: synchronous data writing memory and Hard Disk
No_root_squash: when the user accesses the shared folder with the root user, the root user is not mapped. (Root_squash: the root user is mapped to an anonymous user when the root user accesses the shared folder)
No_subtree_check: the permission of the parent directory is not checked.
2.2-nfs is an RPC program. before using it, you need to map the port and set it through rpcbind:

Sudo service rpcbind restart

2.3-restart the nfs service:

Sudo service restartnfs-kernel-server restart

2.4-test
Run the following command to display the shared directory:

Showmount-e

(3) attaching commands

Sudo mount-t nfs ***. ***:/home/USER/nfs-client/
* **. ** Is the IP address of the NFS server.

If you want to enable automatic mounting:
Run the above command sudo mount-t nfs ***. ***. ***. * **:/home/USER/nfs-clinet/write to/etc/rc. local file.
