On a Debian distribution (Mint, Ubuntu), the apt-get install command can be used to install PureFTPd. On a Red Hat distribution (CentOS, Fedora, Red Hat), the dnf install or yum install command can be used to install PureFTPd.

dnf install pure-ftpd

If pure-ftpd cannot be found, you may need to add the EPEL (Extra Packages for Enterprise Linux) repo.

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

The ps command can be used to determine if your system is using init or systemd. If PID 1 is init, then you will use the service command. If PID 1 is systemd, then you will use the systemctl command.

If your system is using systemd, use the systemctl command to start and enable Pure-FTPd.

systemctl enable pure-ftpd
systemctl start pure-ftpd
systemctl status pure-ftpd

If your system is using init, use the chkconfig and service commands to start and enable Pure-FTPd.

chkconfig pure-ftpd on
service pure-ftpd start
service pure-ftpd status

If there is a firewall, such as iptables or firewalld, allow port 21 for FTP connections or port 22 for SFTP connections.

firewall-cmd --add-protocol=ftp --permanent
firewall-cmd --reload

At this point, you should be able to make an anoymous, unsecured connection to Pure-FTPd.
