SFTP不能生效

Go to Shell (SSH)

Edit /etc/ssh/sshd_config using the text editor of your choice (vim, vi, pico, nano etc)

Add in

Subsystem sftp /usr/libexec/openssh/sftp-server

at the end of the file. Make sure that is the right location. You can check by running this in shell

locate sftp-server

Make sure the output matches the path above (but that's usually the default path)

Restart SSH

/etc/init.d/sshd restart
