# Example config file/etc/vsftpd. conf # The default compiled in settings are fairly paranoid. this sample file # loosens things up a bit, to make the ftp daemon more usable. # Please see vsftpd. conf.5 for all compiled in defaults. # read this: This example file is NOT an exhaustive list of vsftpd options. # Please read the vsftpd. conf.5 manual page to get a full idea of vsftpd's # capabilities. # Allow anonymous FTP?

3. add an FTP account
The account name is "cent" and the password is "cent"
[Root @ localhost ~] # Useradd cent-s/sbin/nologin [root @ localhost ~] # Passwd cent |
4. edit the user_list file to allow cent users to access FTP
|
[Root @ localhost ~] # Vi/etc/vsftpd/user_list |
# Vsftpd userlist # If userlist_deny = NO, only allow users in this file # If userlist_deny = YES (default), never allow users in this file, and # do not even prompt for a password. # Note that the default vsftpd pam config also checks/etc/vsftpd/ftpusers # for users that are denied. rootbindaemonadmlpsyncshutdownhaltmailnewsuucpoperatorgamesnobodycent |
5. create our root directory and set access permissions
[Root @ localhost ~] # Mkdir/var/public_root [root @ localhost ~] # Chown-R cent/var/public_root [root @ localhost ~] # Chmod-R 755/var/public_root |
6. enable the vsftpd service
|
[Root @ localhost ~] # Service vsftpd start |
7. the vsftp service is enabled by default.
|
[Root @ localhost var] # chkconfig vsftpd on |
How to uninstall vsftpd from centos
If vsftpd is installed on the server, you need to uninstall vsftpd if a configuration error occurs.

Warning:/etc/vsftpd/user_list saved as/etc/vsftpd/user_list.rpmsave
Warning:/etc/vsftpd/ftpusers saved as/etc/vsftpd/ftpusers. rpmsave # The vsftp user list file will be backed up when you delete the file.
Check whether vsftpd is uninstalled, and perform the stop and start operations:
|
[Root @ localhost ~] #/Sbin/service vsftpd stop |
Vsftpd: unrecognized service # vsftpd not found
|
[Root @ localhost ~] #/Sbin/service vsftpd start |
Vsftpd: unrecognized service # vsftpd cannot be found. remember to stop vsftpd before uninstalling vsftpd.
