to enable FTP on Redhat on you have to follow to follow the below step,you need to define which user will use the FTP, in this article i will use root user :
Edit the files /etc/vsftpd.ftpusers and /etc/vsftpd.user_list looks like :
#
# List of users denied access to the FTP server, see ftpusers(4).
#
root
daemon
bin
sys
adm
lp
uucp
nuucp
dladm
netadm
netcfg
smmsp
xvm
mysql
openldap
webservd
nobody
noaccess
nobody4
unknown
zfssnap
aiuser
and remove root user from each file.
You can control ftp as services from
/etc/init.d/vsftpd
