Example 2: FTP Installation

Example Scenario: Managing the FTP Server (vsftpd)

1. Installing the FTP Server (vsftpd):

# Install vsftpd package sudo yum install vsftpd

2. Configuring the FTP Server (vsftpd):
   • Edit the configuration file to customize the FTP server settings.

sudo nano /etc/vsftpd/vsftpd.conf

• For example, you can make changes like enabling anonymous access or specifying a custom directory:

anonymous_enable=YES anon_root=/var/ftp/pub

• Save the file and exit the editor.

3. Starting and Enabling the FTP Server (vsftpd):

# Start vsftpd service 
sudo systemctl start vsftpd # Enable vsftpd to start on boot sudo systemctl enable vsftpd

4. Troubleshooting Installation:
   • Scenario: Let’s simulate a scenario where the FTP server fails to start due to a configuration error.

# Introduce a configuration error (e.g., an invalid option) in vsftpd.conf 
sudo nano /etc/vsftpd/vsftpd.conf

• Make an intentional error in the configuration file and save it.

# Try to start vsftpd service (which will fail due to the error) 
sudo systemctl start vsftpd

• Students will receive an error message indicating that there’s a problem with the configuration. They should then troubleshoot the issue by identifying and correcting the error.

# Correct the configuration error 
sudo nano /etc/vsftpd/vsftpd.conf

• After correcting the error, try to start the vsftpd service again.

sudo systemctl start vsftpd

5. Removing the FTP Server (vsftpd):

# Stop the vsftpd service (if it's running) 
sudo systemctl stop vsftpd 
# Disable vsftpd from starting on boot 
sudo systemctl disable vsftpd 
# Remove the vsftpd package 
sudo yum remove vsftpd

Notes:

• This example provides hands-on experience with managing an FTP server, including installation, configuration, and removal.
• The troubleshooting scenario simulates a real-world situation where a configuration error may prevent the FTP server from starting. Students will learn how to identify and correct such issues.
