This article mainly introduces "how to set up tftp and nfs server on Ubuntu system". In daily operation, I believe many people have doubts about how to set up tftp and nfs server on Ubuntu system. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the questions of "how to set up tftp and nfs server on Ubuntu system". Next, please follow the editor to study!

Set up a tftp server

In the process of embedded linux development, you need to use tftp to download files from the Linux host to the board, so you need

To install the tftp server on the host linux system.

The method to install tftp server in Ubuntu-9.10 is as follows:

Installation program

Install tftp tftpd through software management, the former is the client and the latter is the service program. The system will be selected according to the dependency.

Openbsd-inetd . Enter the command under the terminal of Ubuntu as follows:

The code is as follows:

Sudo apt-get install tftp tftpd

Create a tftpboot under the root directory / directory and change the attribute to 777

The code is as follows:

Cd /

Sudo mkdir tftpboot

Sudo chmod 777 tftpboot

Modify the storage directory

The code is as follows:

Sudo vi / etc/inetd.conf

Tftp dgram udp wait nobody / usr/sbin/tcpd / usr/sbin/in.tftpd / tftpboot

Restart the service:

The code is as follows:

Sudo / etc/init.d/openbsd-inetd restart

Sudo in.tftpd-l / tftpboot

Test the tftp server

Create a new file under the / tftpboot folder

The code is as follows:

Cd / tftpboot

Touch test

Go to another folder

The code is as follows:

Tftp 127.0.0.1

Tftp > get test

Set up a nfs server

In the development of embedded linux, it is often necessary to use nfs to facilitate program debugging. With nfs, users can

The root file system to be used by the board is placed in the host directory, and the development board is mounted to this directory through Ethernet and this

The files in the directory are used as the contents of the root file system, so that the updated user's program is not as good as the root file system of the rewriting board.

The system can be reused, which can greatly speed up the debugging of the program.

The steps to install the nfs server under Ubuntu are as follows:

Install NFS server side and client side

The code is as follows:

Sudo apt-get install nfs-kernel-server nfs-common portmap

The purpose of installing the client is to test the NFS service locally.

Configure portmap

You can choose either of the two methods:

(1)

The code is as follows:

Sudo emacs / etc/default/portmap

Remove-I 127.0.0.1

(2)

The code is as follows:

Sudo dpkg-reconfigure portmap

Select "No" after running

It is also important to look at the current nfs and portmap using the sysv-rc-conf (not chkconfig) tool

If off, use sudo sysv-rc-conf portmap on or sudo sysv-rc-conf nfs-kernel-server on

open

Configure mount directories and permissions

The code is as follows:

Emacs / etc/exports

My configuration is as follows:

The code is as follows:

# / etc/exports: the access control list for filesystems which may be exported

# to NFS clients. See exports (5).

#

# Example for NFSv2 and NFSv3:

# / srv/homes hostname1 (rw,sync) hostname2 (ro,sync)

#

# Example for NFSv4:

# / srv/nfs4 gss/krb5i (rw,sync,fsid=0,crossmnt)

# / srv/nfs4/homes gss/krb5i (rw,sync)

#

/ nfsboot * (rw,sync)

Explain:

# the rest is explanation.

/ nfsboot is a shared directory of NFS. * means that any IP can share this directory. You can change it to a restricted IP,rw.

Represents permissions, and sync is the default.

Update exports files

As long as you change / etc/exports, you cannot update this file through sudo exportfs-r

Restart the NFS service

The code is as follows:

Sudo / etc/init.d/portmap start

Sudo / etc/init.d/nfs-kernel-server restart restart nfs service

Conduct a test

Try mounting the local disk (my linux system IP is 202.198.137.18, mount / home/nfsboot to / mnt)

The code is as follows:

$sudo mount 202.198.137.18:/nfsboot / mnt

Run $df to see the result

The code is as follows:

$sudo umount / mnt
