FTP(File Transfer Protocol,文件傳輸協(xié)議)是一種用于在網(wǎng)絡(luò)上進(jìn)行文件傳輸?shù)膽?yīng)用層協(xié)議，本文將介紹如何在CentOS系統(tǒng)中配置FTP服務(wù)器，以便用戶可以通過(guò)FTP協(xié)議在不同設(shè)備之間傳輸文件。

安裝vsftpd

1、更新系統(tǒng)軟件包

在配置FTP服務(wù)器之前，首先需要確保系統(tǒng)已經(jīng)更新到最新版本，打開(kāi)終端，輸入以下命令：

sudo yum update

2、安裝vsftpd

vsftpd是CentOS系統(tǒng)中一個(gè)常用的FTP服務(wù)器軟件，通過(guò)以下命令安裝vsftpd:

sudo yum install vsftpd

3、啟動(dòng)vsftpd服務(wù)并設(shè)置開(kāi)機(jī)自啟

安裝完成后，啟動(dòng)vsftpd服務(wù)并設(shè)置開(kāi)機(jī)自啟：

sudo systemctl start vsftpd
sudo systemctl enable vsftpd

4、配置防火墻

為了保證FTP服務(wù)器的安全性，需要配置防火墻允許FTP服務(wù)的端口，使用以下命令開(kāi)放21端口(FTP默認(rèn)端口):

sudo firewall-cmd --permanent --add-port=21/tcp
sudo firewall-cmd --reload

配置虛擬用戶及目錄權(quán)限

1、創(chuàng)建虛擬用戶

為了讓用戶能夠通過(guò)FTP登錄并訪問(wèn)其自己的文件，需要為每個(gè)用戶創(chuàng)建一個(gè)虛擬用戶，備份原始的vsftpd配置文件：

sudo cp /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.conf.bak

編輯配置文件：

sudo vi /etc/vsftpd/vsftpd.conf

找到以下行并取消注釋(刪除行首的符號(hào)):

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)

保存并退出編輯器，接下來(lái)，創(chuàng)建虛擬用戶，創(chuàng)建一個(gè)名為user1的用戶，密碼為password1:

sudo useradd -m user1 -s /sbin/nologin -p password1

2、設(shè)置目錄權(quán)限和所屬用戶組

為了讓虛擬用戶能夠訪問(wèn)其自己的文件，需要為其分配相應(yīng)的目錄權(quán)限和所屬用戶組，為user1分配/home/user1目錄及其子目錄的權(quán)限，并將其所屬用戶組更改為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
