# firewall-cmd -zone=public -permanent -add-service=ftpĤ. Next, in order to allow access to FTP services from external systems, we have to open port 21, where the FTP daemons are listening as follows: # firewall-cmd -zone=public -permanent -add-port=21/tcp After the installation completes, the service will be disabled at first, so we need to start it manually for the time being and enable it to start automatically from the next system boot as well: # systemctl start vsftpdģ. Installing vsftpd server is straight forward, just run the following command in the terminal. Note that all the commands in this guide will be run as root, in case you are not operating the server with the root account, use the sudo command to gain root privileges. In this guide, we will describe the steps to install, configure and secure a FTP server ( VSFTPD stands for “ Very Secure FTP Daemon“) in CentOS/ RHEL 7 and Fedora distributions.

FTP ( File Transfer Protocol) is a traditional and widely used standard tool for transferring files between a server and clients over a network, especially where no authentication is necessary (permits anonymous users to connect to a server).
