How to set up an SFTP server on Linux

Take, for instance, the ability to easily configure CentOS 7 to work as an SFTP server. If you aren’t sure about SFTP, it is the FTP service built into Secure Shell (SSH), which allows users to securely push and pull files to and from the server, using SSH. With CentOS 7, there’s no third party software to install to make this work—everything is installed out of the box. There is, however, a slight bit of work to be done to get this configured.
