In this guide, we will see how to configure an FTP server (ProFTPd) to transfer files between your PC and your server.
Prerequisites
A newly deployed Rcs CentOS server instance.
A Sudo user.
Installation
Update the system.
yum check-update
Official RHEL/CentOS 6/7 repositories do not provide any binary packages for ProFTPD Server, so you need to add extra package repositories on your system provided by EPEL 6/7 repo using one of the following commands.
CentOS 6:
sudo rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
CentOS 7:
sudo rpm -Uvh http://ftp.astral.ro/mirrors/fedora/pub/epel/beta/7/x86_64/epel-release-7-0.2.noarch.rpm
Download all of the metadata for the currently enabled yum repos.
sudo yum makecache
Install proftpd.
sudo yum install proftpd
Install ftp.
sudo yum install ftp
Configuration
Open the ProFTPd configuration file.
sudo nano /etc/proftpd.conf
The file will resemble the following text.
The file will resemble the following text.
# This is the ProFTPD configuration file
#
# See: http://www.proftpd.org/docs/directives/linked/by-name.html
# Server Config - config used for anything outside a <VirtualHost> or <Global> $
# See: http://www.proftpd.org/docs/howto/Vhost.html
ServerName "ProFTPD server"
ServerIdent on "FTP Server ready."
ServerAdmin root@localhost
DefaultServer on
# Cause every FTP user except adm to be chrooted into their home directory
# Aliasing /etc/security/pam_env.conf into the chroot allows pam_env to
# work at session-end time (http://bugzilla.redhat.com/477120)
VRootEngine on
DefaultRoot ~ !adm
VRootAlias /etc/security/pam_env.conf etc/security/pam_env$
# Use pam to authenticate (default) and be authoritative
AuthPAMConfig proftpd
AuthOrder mod_auth_pam.c* mod_auth_unix.c
# If you use NIS/YP/LDAP you may need to disable PersistentPasswd
#PersistentPasswd off
# Don't do reverse DNS lookups (hangs on DNS problems)
UseReverseDNS off
# Set the user and group that the server runs as
User nobody
Group nobody
# To prevent DoS attacks, set the maximum number of child processes
# to 20. If you need to allow more than 20 concurrent connections
# at once, simply increase this value. Note that this ONLY works
# in standalone mode; in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd)
MaxInstances 20

Main configuration directives
ServerName: Specifies the name of the FTP server. This name will be displayed when clients connect to the server.DefaultRoot: Controls the default root directory assigned to a user upon login.MaxInstances: The maximum number of simultaneous connections you want to allow on your FTP server.
Now, we have to change the ServerName.
ServerName : the name of your FTP server
Note: By default, someone who connects to the FTP server can access all of the server folders, so it's recommended to enable the option DefaultRoot.
DefaultRoot ~ !adm
After the configuration has been changed, restart the server.
sudo service proftpd restart
Note: If an error line is displayed as "unable to resolve host", be aware that it does not matter and you can ignore it.
Add an FTP user
Add a user.
useradd --shell /bin/false myuser
Create the home directory of our user "myuser".
mkdir /home/myuser
Change the ownership of that directory to the user and group "myuser".
chown myuser:myuser /home/myuser/
Set a password for the user "myuser".
passwd myuser
