How to enable FTP service under Linux
1. First, the server needs to install ftp software. Check whether the ftp software has been installed:
#which vsftpd
If you see a vsftpd directory, it means that the server has installed ftp software
2 . Check the ftp server status
#service vsftpd status
3. Start the ftp server
#service vsftpd start
4. Restart the ftp server
#service vsftpd restart
5. Check whether the service is started
#netstat -an | grep 21
tcp 0 0 0.0.0.0:21 0.0.0.0:* tcp LISTEN
If you see the above information, it proves that the ftp service has been started.
6. If you need to enable the root user's ftp permissions, you need to modify the following two files
#vi /etc/vsftpd.ftpusers and comment out root
#vi /etc/vsftpd.user_list also comment out root
Then restart ftp Serve.
