How to Start and Stop vsftpd in Linux

vsftpd RPM installs the /etc/rc.d/init.d/vsftpd script, which can be accessed via  /sbin/service command.

To start the server, as root :

/sbin/service vsftpd start

To stop the server, as root :

/sbin/service vsftpd stop

To restart the server, as root type:
/sbin/service vsftpd restart

The condrestart (conditional restart) option only starts vsftpd if it is currently running. 
It does not start the daemon if it is not running.
