11.3. Sharing the installation files on an FTP server

Procedure

1. Install the vsftpd package by running the following command as root:

   # dnf install vsftpd

2. Open and edit the /etc/vsftpd/vsftpd.conf configuration file in a text editor.

   1. Change the line anonymous_enable=NO to anonymous_enable=YES
   2. Change the line write_enable=YES to write_enable=NO.

   3. Add lines pasv_min_port=min_port and pasv_max_port=max_port. Replace min_port and max_port with the port number range used by the FTP server in passive mode, for example, 10021 and 10031.

      This step can be necessary in network environments featuring various firewall/NAT setups.

   4. Optional: Add custom changes to your configuration. For available options, see the vsftpd.conf(5) man page. This procedure assumes that default options are used.

3. Configure the firewall to allow the FTP port and port range from the previous step:

   # firewall-cmd --add-port min_port-max_port/tcp --permanent

   Replace min_port-max_port with the port numbers you entered into the /etc/vsftpd/vsftpd.conf configuration file.

4. Configure the firewall to allow FTP service.

   # firewall-cmd --add-service ftp --permanent

5. Reload the firewall to apply the new rules.

   # firewall-cmd --reload

6. Copy the Kickstart file to the FTP server into the /var/ftp/ directory or its subdirectory.

7. Ensure that the correct SELinux context and access mode is set on the file:

   # restorecon -r /var/ftp/your-kickstart-file.ks
   # chmod 444 /var/ftp/your-kickstart-file.ks

8. Start the vsftpd service:

   # systemctl enable --now vsftpd.service

   If the service was running before you changed the /etc/vsftpd/vsftpd.conf file, restart the service to load the edited file:

   # systemctl restart vsftpd.service

   The Kickstart file is now accessible and ready to be used for installations by systems on the same network.

   注意

   When configuring the installation source, use ftp:// as the protocol, the server’s host name or IP address, and the path of the Kickstart file, relative to the FTP server root. For example, if the server’s host name is myserver.example.com and you have copied the file to /var/ftp/my-ks.cfg, specify ftp://myserver.example.com/my-ks.cfg as the installation source.
