CentOS 7 搭建FTP

ftp虚拟用户实验报告
实验环境：一台CentOS7系统的服务器，一台客户机用作验证（windows、linux都可）
实验要求：使用CentOS7搭建FTP服务器。
实验步骤：
服务端搭建
[root@localhost ~]# vim /etc/selinux/config

This file controls the state of SELinux on the system.
SELINUX= can take one of these three values:
enforcing - SELinux security policy is enforced.
permissive - SELinux prints warnings instead of enforcing.
disabled - No SELinux policy is loaded.
SELINUX=disabled
SELINUXTYPE= can take one of three two values:
targeted - Targeted processes are protected,
minimum - Modification of targeted policy. Only selected processes are protected.
mls - Multi Level Security protection.
SELINUXTYPE=targeted
