Ubuntu prohibits FTP users from logging on to the system

This year, our company used Ubuntu servers and previously used CentOS. In the afternoon, I set up a community for the company and set up an FTP. In consideration of security, the FTP user is prohibited from logging on to the system. I set the FTP User shell such as ftp1 to nologin, I couldn't log on to the test FTP. I found that there are many differences between Ubuntu and CentOS, and there are some differences in apache configuration. The company's server system is Ubuntu11.10. # Whichnologin/

Therefore, after this file,/usr/sbin/nologin is added.
