The error message "vsftpd 500 Oops: vsftpd: cannot open config file" is returned.

To the/etc/init. d/directory

Input: vsftpd restart

The error message "500 Oops: vsftpd: cannot open config file: restart" is displayed"

At that time, I was depressed...

Then I tried: vsftpd stop.

An error message "500 Oops: vsftpd: cannot open config file: Stop" is returned"

Next: vsftpd

"500 Oops: cocould not bind listening IPv4 socket"

It turns out that the input of vsftpd is not the vsftpd in this directory, but the vsftpd in the/usr/sbin/directory (because the root user directory is this ...) Run/etc/init. d/vsftpd must enter the complete path. no matter where you are, enter and run the entire path. for example, I am now in/etc/init. d/directory, but I want to execute vsftpd restart, or enter:/etc/init. d/vsftpd restart
