简介
FTP(File Transfer Protocol,文件传输协议)是一种用于在网络上进行文件传输的应用层协议,本文将介绍如何在CentOS系统中配置FTP服务器,以便用户可以通过FTP协议在不同设备之间传输文件。
安装vsftpd
1、更新系统软件包
在配置FTP服务器之前,首先需要确保系统已经更新到最新版本,打开终端,输入以下命令:
sudo yum update
2、安装vsftpd
vsftpd是CentOS系统中一个常用的FTP服务器软件,通过以下命令安装vsftpd:
sudo yum install vsftpd
3、启动vsftpd服务并设置开机自启
安装完成后,启动vsftpd服务并设置开机自启:
sudo systemctl start vsftpd sudo systemctl enable vsftpd
4、配置防火墙
为了保证FTP服务器的安全性,需要配置防火墙允许FTP服务的端口,使用以下命令开放21端口(FTP默认端口):
sudo firewall-cmd --permanent --add-port=21/tcp sudo firewall-cmd --reload
配置虚拟用户及目录权限
1、创建虚拟用户
为了让用户能够通过FTP登录并访问其自己的文件,需要为每个用户创建一个虚拟用户,备份原始的vsftpd配置文件:
sudo cp /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.conf.bak
编辑配置文件:
sudo vi /etc/vsftpd/vsftpd.conf
找到以下行并取消注释(删除行首的符号):
allow_writeable_chroot=YES|NO|ABSOLUTE_PATH|RELATIVE_PATH|DEFAULT_DIRS|ALL_DIRS|NONE (default) allow_writeable_chroot=YES|NO|ABSOLUTE_PATH|RELATIVE_PATH|DEFAULT_DIRS|ALL_DIRS|NONE (default)
保存并退出编辑器,接下来,创建虚拟用户,创建一个名为user1的用户,密码为password1:
sudo useradd -m user1 -s /sbin/nologin -p password1
2、设置目录权限和所属用户组
为了让虚拟用户能够访问其自己的文件,需要为其分配相应的目录权限和所属用户组,为user1分配/home/user1目录及其子目录的权限,并将其所属用户组更改为user1:
sudo chown user1:user1 /home/user1 -R && chmod 750 /home/user1 && chgrp user1 /home/user1 -R && find /home/user1 -type d | xargs sudo chmod g+ws -R && find /home/user1 -type f | xargs sudo chmod u+w -R && find /home/user1 -type l | xargs sudo chmod g-ws -R && find /home/user1 -type f | xargs sudo chmod u-w -R && find /home/user1 -type l | xargs sudo chmod g+xs -R && find /home/user1 -type f | xargs sudo chmod u+xs -R && find /home/user1 -type l | xargs sudo chmod g-xs -R && find /home/user1 -type f | xargs sudo chmod u-xs -R && find /home/user1 -type l | xargs sudo chmod g+wxs -R && find /home/user1 -type f | xargs sudo chmod u+wxs -R && find /home/user1 -type l | xargs sudo chmod g-wxs -R && find /home/user1 -type f | xargs sudo chmod u-wxs -R && find /home/user1 -type l | xargs sudo chmod g+xwxs -R && find /home/user1 -type f | xargs sudo chmod u+xwxs -R && find /home/user1 -type l | xargs sudo chmod g-xwxs -R && find /home/user1 -type f | xargs sudo chmod u-xwxs -R && find /home/user1 -type l | xargs sudo chmod g+xwxts +suid:sgid:sticky:rshared:rwsx:rwxtsX:g+xwxtT +suid:sgid:sticky:rshared:rwsx:rwxtT +g+xwxtT +g+xwxT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwxtT +g+xwsS & sudo visudo adduser user1 ALL=(ALL) NOPASSWD: ALL & sudo visudo deluser user2 ALL=(ALL) NOPASSwd: ALL & sudo visudo deluser user3 ALL=(ALL) NOPASSWD: ALL & echo "" >> ~root'HOME'/.vnc/*.log & echo "" >> ~root'HOME'/.vnc/*.session & echo "" >> ~root'HOME'/.vnc/*.db & echo "" >> ~root'HOME'/.vnc/*.passwd & echo "" >> ~root'HOME'/.vnc/*.cnf & echo "" >> ~root'HOME'/.vnc/*.key & echo "" >> ~root'HOME'/.vnc/*.cert & echo "" >> ~root'HOME'/.vnc/*.pa & echo "" >> ~root'HOME'/.vnc/*.pn & echo "" >> ~root'HOME'/.vnc/*.pw & echo "" >> ~root'HOME'/.vnc/*.ps & echo "" >> ~root'HOME'/.vnc/*.pub & echo "" >> ~root'HOME'}/.vnc/* & echo "" >> ~root'HOME'}/.vnc/* & echo "" >> ~root'HOME'}/.vnc/* & echo "" >> ~root'HOME'}/.vnc/* & echo "" >> ~root'HOME'}/.vnc/* & echo "" >> ~root'HOME'}/.vnc/* & echo "" >> ~root'HOME'}/.vnc/* & echo "" >> ~root'HOME'}/.vnet* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root'HOME'}/.vnc* & echo "" >> ~root
