4.2 Setting up FTP-related directories

After installation, an FTP directory will be added under/srv

At the same time, the system will add a user group named FTP, which can be viewed by the following code:

sudo cat    /etc/shadow

As follows:

In the/srv/ftp directory, we created two directories named upload and download, respectively, for uploading and downloading:

Cd/srv/ftp/sudo mkdir downloadsudo mkdir upload

Next we set permissions for several of the directories we just created

The command reference is as follows:

sudo chmod 755/srv/ftpsudo chmod 777/srv/ftp/uploadsudo chmod 755/srv/ftp/download

So, on the one hand we allow the user group FTP access/home/ftp (anonymous access), on the one hand to the user group FTP/srv/ftp/upload write rights, so users on the network can easily upload files, but note that when they upload, upload the Files have only root permissions on these files, that is, this directory can only be used for uploading, unable to download the files, in addition to the user group FTP to/home/ftp/download read rights, and we copy into the directory of the file for the user group usually have read rights, Therefore, users on the network can and can only download files from this directory. So as to meet our prior requirements.

4.3 Start ftp:

sudo service vsftpd start

View all current processes:

Ps-e

As follows

The most basic configuration of server-side vsftp has been completed, VSFTPD is turned on (Ubuntu does not have a firewall installed by default, if there is an installation, please temporarily shut down)

And by the way, the command to turn off ftp:

sudo service vsftpd stop

Process vsftpd View command:

Pgrep vsftpd

4.4 vsftpd Set up the user directory, if you set up anonymous users can also log in to upload words ~ This can save the ~

• Add user Ftpuser and set its directory to/home/nation/ftp/upload

sudo useradd-g ftpgroup-d/home/nation/ftp/upload-m ftpuser

(Note: G: The user's Group D: the location to create the user's own directory given m: Do not establish the default home directory, that is, there is no own directory under//)
