First thing first. What is ProFTP?
ProFTPD is a stable and full-featured FTP Server. It can be run as a standalone server or from xinetd. It supports anonymous, authenticated logins, authenticated with LDAP directories or even sql databases.
Installation of ProFTP Server
yum install proftpd chkconfig --levels 235 ptoftpd on
To enable anonymous logins, edit the /etc/sysconfig/proftpd file
# vim /etc/sysconfig/proftpd
Inside the /etc/sysconfig/proftpd file
PROFTPD_OPTIONS="-DANONYMOUS_FTP"
# service proftpd restart
The default home directory of the anonymous logins is /var/ftp/
The default directory to place content for anymous users to put is at /var/ftp/pub
The default directory for anonymous users to upload to /var/ftp/upload
2. Virtual Hosting
Unfortunately, FTP require different IP Address for each site even though it is supposed to be virtual hosting. Unlike HTTP protocol which includes a host header field.
Assuming you have several IP Addresses which you can use uniquely for your Virtual Hosting, you still need to set up IP Alias on the network card and a "VirtualHost" section in the proftpd.conf
Create a Network Card Alias
Step 2a - Create a network card alias for the network card
# touch /etc/sysconfig/network-scripts/ifcfg-eth0:N (where N is the alias number)
Step 2b: Inside ifcfg-eth0:N
DEVICE=eth0:1 ONBOOT=yes BOOTPROTO=static IPADDR=192.168.1.2 HARDWARE=xx:xx:xx:xx:xx:xx
Step 2c: Restart Network Service
# service network restart
Step 3: Configure the VirtualHost inside the /etc/proftpd.conf
The script is rather long, you can get a sample from http://www.proftpd.org/docs/configs/virtual_authuserfile.conf
Bascially, you can change the Default Chdir to a new path ie /var/ftp/site2/pub. You can also change the message /var/ftp/site2/welcome.msg
