Install and configure the FTP server in CentOS 7

Install and configure the FTP server in CentOS 7.

Suppose we have the following requirements:

Path Permission Remarks
/Ftp/open All staff of the company, including guests, can access Read-Only
/Ftp/private Only Alice, Jack, and Tom are allowed to access

Alice and Jack can only be downloaded,

Tom can upload all files using a virtual account

Install FTP

// Use yum for Installation
# Yum-yinstall ftp vsftpd
// Or use rpm to install the following two packages
Ftp-0.17-66.el7.x86_64
Vsftpd-3.0.2-9.el7.x86_64
// You need to install a db package to encrypt the account information of a virtual user.
// This package is installed in centos7 by default.
# Rpm-qf/usr/bin/db_load
Libdb-utils-5.3.21-17.el7_0.1.x86_64
