Simple and practical ubuntu ftp setup

Ubuntu's practical and simple ftp setup-Linux Enterprise Application-Linux server application information. The following is a detailed description. After implementing the virtual host setting for Multiple Apache users, these users generally choose to use ftp to upload their web content, which requires us to set up FTP services for them.

The FTP server that comes with Ubuntu is vsftpd. Two articles in this article are also recommended. I will provide one article through practice.

1) install vsftpd

It is not difficult to install software in Ubuntu. Enter:

Sudo apt-get install vsftpd may prompt you to use the CD, put it in, and press Enter.

After installation, an ftp directory is created under/home. At this time, you can try to access the ftp: // ip address. You can see an ftp space with blank content.

By default, anonymous users can download files, but cannot write or upload files.

2) set the vsftpd. conf file

Now, we need to make anonymous users inaccessible and enter the user password on linux before they can access the contents in their own directories.

First, find the file for setting vsftpd, which is located in/etc/vsftpd. conf.

Back up this file before modification:

Sudo cp/etc/vsftpd. conf/etc/vsftpd. conf. old can be changed:
# Do not allow anonymous users to use

# Anonymous_enable = YES

# Local_enable = YES is available for local users

# Write_enable = YES

# File information in a directory is not required

# Dirmessage_enable = YES

# Add a banner prompt

Ftpd_banner = Hello ~~

# Maximum number of users on the FTP server

Max_clients = 100

# Restrict processes of each IP Address

Max_per_ip = 5

# Maximum transmission rate

(B/s) local_max_rates = 256000

# Hiding accounts

Hide_ids = YES

Okay. Restart the ftp server to check the effect.

Is it the same after restart as before? Haha, This is the default ftp directory. Let's delete it and check again. How is it? Enter the user name and password.

New Problems

1. After Entering the username and password, the user's root directory is displayed, and our WEB content is in the public_html directory.

2. You can jump to any other directory (very dangerous ..)

To solve these problems, we have to set vsftpd. conf.

# Start the chroot list (Change root) chroot_list_enable = YES # specify the list location (I use the default address)

Chroot_list_file =/etc/vsftpd. chroot_list next we have to write it on vsftpd. chroot_list. We want to limit which users we want to avoid "drifting "..

Currently, linyupark is a user, so you only need to write sudo nano to it.

In this way, we have solved 2nd problems. login users can only activity in their user folders. Below we want to be more aggressive, so that they can only activity in public_html.

Still find vsftpd. conf

# This is not in the default setting. Add user_config_dir =/etc/and define a folder for setting the folder address for individual users. Create a folder Based on the address you set, create a file with the same username as the nano file:

# The root address of the local user. If the user is linyuparklocal_root =/home/linyupark/public_html, restart the server. Let's see the effect.
