Lets see how we can configure a secure FTP server on CentOS RHEL 6 / 7
First, you need to install the vsftp package on your server
yum install -y vsftpd
Once installed, lets start editing the configuration file,
vim /etc/vsftpd/vsftpd.conf
Line #12 disable anonymous FTP access, with the below configuration change.
anonymous_enable=NO
Chroot / Jail FTP users to their home directory
by default, any FTP user can login and access the entire files on the systems including /etc which is extremely dangerous.
Line #100 , enable the below setting.
chroot_local_user=YES
also add the below new setting to the vsftpd.conf file
allow_writeable_chroot=YES
Now, Start the service and enable the service on boot.
systemctl restart vsftpd systemctl enable vsftpd
Now the FTP users will be able to login and access their home directory only.
