1. First check to see if VSFTPD is installed in the system

Rpm-qa | grep vsftpd

For example, if the display results are as follows, the VSFPTD3.0 FTP server is installed

[email protected] sbin]# Rpm-qa | grep vsftpd
Vsftpd-3.0.2-9.el7.x86_64

2. Stop the VSFTPD server

/bin/sytemctl Stop Vsftpd.service

3. Use the RPM command to clear

Rpm-e vsftpd-3.0.2-9.e17.x86_64

[Email protected] sbin]# rpm-e vsftpd-3.0.2-9.e17.x86_64
Error: Package vsftpd-3.0.2-9.e17.x86_64 not installed
[ as can be seen here, after the installation of the VSFTPD software is cleared, several important configuration files are still automatically reserved.] If you're sure you don't need one, you can delete it manually.

You can use the RM command.

4. Other residual file cleanup

Other residual files may but do not include: Files under the a./etc/vsftpd/directory B. configured system self-boot services, and so on. These need to be handled manually, of course, can not be dealt with, the impact is small.

You can use the command: Find/-name ' *vsftpd* ' to locate the file that contains the VSFTPD typeface, and then make sure to delete it.
