Installing VSFTPD server under Centos 6.5

1. See if VSFTP is installed

[[Email protected] ~] #rpm-qa|grep vsftpd

If vsftpd-2.2.2-13.el6_6.1.x86_64 appears, the VSFTP is already installed.

If no fields such as vsftpd appear, perform the second step;

2. Installing VSFTPD

[[Email protected] ~] # yum-y Install vsftpd

3. Configure the vsftpd.conf file "/etc/vsftpd/vsftpd.conf"

#Example config file/etc/vsftpd/vsftpd.conf##The default compiled in Settings is 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 a 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?

4. New FTP Account

[[Email protected] ~] # useradd cookie-s/sbin/nologin [[Email protected] ~] # passwd Cookies

5. Edit the User_list file, allow new account access to FTP "can also delete the original account, and then add the FTP account allowed to access"

 #   vsftpd userlist  #   #   #   do not even prompt for a password.  #   Note that the default Vsftpd Pam config also checks/etc/vsftpd/ftpusers  #   for users, that is denied.  rootbindaemonadmlpsyncshutdownhalt  mail  newsuucpoperatorgamesnobodycookie 

6. Create a new FTP access root directory and set access permissions "directory name has been noted in vsftpd.conf, if the FTP can upload files, you need to change the permissions to 777"

[[Email protected] ~] # mkdir/var/www/html/ftp [[Email protected] ~] # chown-r cookie/var/www/html/ftp [[Email protected] ~] #

7. Turn on VSFTPD service

[[Email protected] ~] # Service vsftpd Start

8. Start the FTP service on boot

var] # chkconfig vsftpd on
