VSFTP installation and Application

Background: install an FTP server and store some files and videos.

When the rpm package is installed with VSFTP, the directory to be uploaded to the user is in the/root directory. In this way, if there are too many FTP files, it will occupy too many hard disk resources. Therefore, you need to add a new hard disk to store FTP files.

Requirements:

1. Anonymous Users can only download files in/mnt/ftp/public.

2. The local user logs on to the ftp directory/mnt/ftp/home/, which can be uploaded and downloaded.

3. Restrict the disk quota of users. each user has a space of 5 MB.

4. the download speed of local users is 1 m/s, while that of anonymous users is 100 k/s.

5. Max connections 3, Max connections per user 2

6. download speed of the local user user1: 10 m/s; download speed of user2: 100 k/s

7. Do not allow user1 to switch directories.

1. Add a hard disk;

Name: RedHat el52 size: 8 GB partition:/mnt/ftp

Because a local user will log on to the Home Directory of the user when logging on to ftp. Therefore, when creating a user, make the user's home directory in the/mnt/ftp/home file. By default, the user's home directory is created in/home/user name.
