Install the ftp service on centos7

Install the ftp service on centos7

Install and configure the FTP server in CentOS 7.

Suppose we have the following requirements:

Path permission remarks

/Ftp/open all staff, including guests, can access read-only

/Ftp/private only allow access by Alice, Jack, and Tom

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

This is usually caused by SELinux. The solution is as follows:

Vi/etc/selinux/config

# Change selinux = enforcing or permissive to disabled and disable selinux,

Setenforce 0

# Enable the selinux policy to take effect immediately

/Etc/init. d/vsftpd restart

# Restart the FTP service
