Install the vsftpd package via yum command:
# yum install vsftpd

Vsftpd Defaults

1. Default port: TCP / UDP - 21 and 20
2. The main configuration file: /etc/vsftpd/vsftpd.conf

Open the configuration file, type:
# vi /etc/vsftpd/vsftpd.conf
Turn off standard ftpd xferlog log format:

xferlog_std_format=NO

Turn on verbose vsftpd log format. The default vsftpd log file is /var/log/vsftpd.log:

log_ftp_protocol=YES

Above to directives will enable logging of all FTP transactions. Lock down users to their home directories:

chroot_local_user=YES

Create warning banners for all FTP users:

banner_file=/etc/vsftpd/issue

Create /etc/vsftpd/issue file with a message compliant with the local site policy or a legal disclaimer:

NOTICE TO USERS

Turn On Vsftpd Service

Turn on vsftpd on boot:
# chkconfig vsftpd on
Start the service:
# service vsftpd start
# netstat -tulpn | grep :21

Configure Iptables To Protect The FTP Server

Open file /etc/sysconfig/iptables, enter:
# vi /etc/sysconfig/iptables
Add the following lines, ensuring that they appear before the final LOG and DROP lines for the RH-Firewall-1-INPUT:

-A RH-Firewall-1-INPUT -m state --state NEW -p tcp --dport 21 -j ACCEPT

Open file /etc/sysconfig/iptables-config, enter:
# vi /etc/sysconfig/iptables-config
Ensure that the space-separated list of modules contains the FTP connection tracking module:

IPTABLES_MODULES="ip_conntrack_ftp"

Save and close the file. Restart firewall:
# service iptables restarthttp://www.cyberciti.biz/tips/rhel-fedora-centos-vsftpd-installation.html
