I assume you are using CentOS.

There are two ways to do this:

To install a ftp client without using a control panel

To install a Control Panel (such as cPanel and Kloxo) which comes with FTP Client pre-installed.

So, if you want to use a FTP Client without using a control panel you can install it by firstly connecting via SSH, then typing the following commands on your SSH Client.

yum install vsftp
you can start the daemon service

vsftpd start
you can also configure it in

/etc/vsftp/vstpd.conf
You might also want to enable vsftp on start-up, so

chkconfig vsftpd on
To make it even more simple, here are the steps:

1) yum install vsftpd
2) /etc/init.d/vsftpd restart
3) useradd username
4) passwd username
And check from FTP client if you get through.

The second way is by install a Control Panel, i will be using Kloxo in this one.

mkdir temp && cd temp
wget http://download.lxlabs.com/download/...tall-master.sh
sh ./kloxo-install-master.sh
Good luck with everything.
