【軟件安裝】CentOS7上安裝FTP軟件——VSFTPD服務搭建

一、前言介紹

FTP(文件傳輸協議)是一種標準的客戶機-服務器網絡協議,允許用戶在遠程網絡之間傳輸文件。

有幾個開源的FTP服務器可用于Linux。最受歡迎和廣泛使用的是pureftpd、proftpd和vsftpd。

在本教程中,我們將在Centos7上安裝vsftpd(非常安全的ftp守護進程)。它是一個穩定、安全和快速的FTP服務器。我們還將向您展示如何配置vsftpd,以將用戶限制到其主目錄,并使用ssl/tls加密整個傳輸。

要獲得更安全和更快的數據傳輸,請使用SCP或SFTP。

二、先決條件

在繼續本教程之前,請確保您以具有sudo權限的用戶身份登錄。(root 登錄可以不用sudo  一般可以省略sudo )

sudo的工作過程如下:

1,當用戶執行sudo時,系統會主動尋找/etc/sudoers文件,判斷該用戶是否有執行sudo的權限

2,確認用戶具有可執行sudo的權限后,讓用戶輸入用戶自己的密碼確認

3,若密碼輸入成功,則開始執行sudo后續的命令

4,root執行sudo時不需要輸入密碼(eudoers文件中有配置root ALL=(ALL) ALL這樣一條規則)

5,若欲切換的身份與執行者的身份相同,也不需要輸入密碼

 

visudo使用vi打開/etc/sudoers文件,但是在保存退出時,visudo會檢查內部語法,避免用戶輸入錯誤信息

visudo需要root權限

[hadoop@localhost ~]$ visudo
visudo:/etc/sudoers:權限不夠
visudo:/etc/sudoers:權限不夠

三、在CentOS 7上安裝vsftpd

1、vsftpd包在默認的CentOS存儲庫中可用。要安裝它,請發出以下命令:

 

sudo yum install vsftpd

2、安裝包后,啟動vsftpd守護進程并使其在啟動時自動啟動,vsftpd服務的狀態來驗證它是否正在運行 

 #設置開機啟動
systemctl enable vsftpd.service

#啟動
systemctl start vsftpd.service

#停止
systemctl stop vsftpd.service

#查看狀態
systemctl status vsftpd.service

#重啟
systemctl restart vsftpd.service

  具體操作如下,操作完成之后都要重啟啟動并且查看狀態的

四、配置vsftpd(重點標記,我自己錯誤了好多次才成功的,錯了就刪除了重新配置)

  配置vsftpd服務涉及編輯/etc/vsftpd/vsftpd.conf配置文件。大多數設置都在配置文件中有很好的文檔記錄。有關所有可用選項,請訪問官方vsftpd頁面。 http://vsftpd.beasts.org/vsftpd_conf.html(官方介紹,比較好用,英文不好的戳這里:http://www.jsfhjj.com/sopcce/p/10743359.html

在下面的部分中,我們將介紹配置安全vsftpd安裝所需的一些重要設置。

1、首先打開vsftpd配置文件:

 vi /etc/vsftpd/vsftpd.conf

2、編輯配置文件(  配置文件 /etc/vsftpd/vsftpd.conf,修改:wq  )

 

anonymous_enable=N0
xferlog_file=/var/log/xferlog
xferlog_std_format=YES
ftpd_banner=Welcome to blah FTP service.
userlist_file=/etc/vsftpd/user_list 
userlist_deny=YES
user_sub_token=$USER 
local_root=/home/$USER/ftp 
pasv_min_port=30000 
pasv_max_port=31000 

 

原來的配置文件如下,記得備份文件哦

  注意:配置完成之后,(重啟)服務,如果服務異常,請輸入(查看狀態命令)服務,服務具體錯誤有提示。

3、設置root 賬號登錄權限

編輯一下文件,重啟服務查看狀態。

vi  /etc/vsftpd/ftpusers  注釋掉 #root
vi  /etc/vsftpd/user_list 注釋掉 #root
vi  /etc/vsftpd/vsftpd.conf write_enable=YES

具體操作如下

[root@centos001 ~]# cd /etc/vsftpd
[root@centos001 vsftpd]# ls
ftpusers  user_list  vsftpd.conf  vsftpd_conf_migrate.sh
[root@centos001 vsftpd]# vi user_list
[root@centos001 vsftpd]# vi ftpusers
[root@centos001 vsftpd]# systemctl restart vsftpd.service

 測試本地FTP

[root@centos-7-06-64-20G ~]# ftp 
ftp> open 127.0.0.1
Connected to 127.0.0.1 (127.0.0.1).
220 welcome to 39...120 ftp vsftpd server.
Name (127.0.0.1:root): root
530 Permission denied.
Login failed.
ftp> quit
221 Goodbye.

 

五、配置vsftpd 創建FTP用戶

 

為了測試我們的FTP服務器,我們將創建一個新用戶。

 

如果您已經擁有要授予FTP訪問權限的用戶,請跳過第1步。
如果在配置文件中設置allow_writeable_chroot = YES,請跳過第3步。
創建一個名為sopftpuser的新用戶:

1、創建一個名為sopftpuser的新用戶,接下來,設置用戶密碼

 

sudo adduser sopftpuser
sudo passwd sopftpuser

 

2、將用戶添加到允許的FTP用戶列表中

 

 echo "sopftpuser" | sudo tee -a /etc/vsftpd/user_list

 

 

 

 

3、創建FTP目錄樹并設置正確的權限

 

 sudo mkdir -p /home/sopftpuser/ftp/

 sudo chmod 550 /home/sopftpuser/ftp

 sudo chmod 750 /home/sopftpuser/ftp/

 sudo chown -R sopftpuser: /home/sopftpuser/ftp

 

如上一節所述,用戶可以將其文件上傳到ftp / upload目錄。

此時,您的FTP服務器功能齊全,您應該可以使用任何可配置為使用TLS加密的FTP客戶端(如FileZilla)連接到您的服務器

 

[root@centos001 ~]# sudo adduser sopftpuser
[root@centos001 ~]# sudo passwd sopftpuser
Changing password for user sopftpuser.
New password: 
BAD PASSWORD: The password is shorter than 8 characters
Retype new password: 
Sorry, passwords do not match.
New password: 
BAD PASSWORD: The password fails the dictionary check - it does not contain enough DIFFERENT characters
Retype new password: 
passwd: all authentication tokens updated successfully.
[root@centos001 ~]# echo "sopftpuser" | sudo tee -a /etc/vsftpd/user_list
sopftpuser
[root@centos001 ~]# sudo mkdir -p /home/sopftpuser/ftp/
[root@centos001 ~]# sudo chmod 550 /home/sopftpuser/ftp
[root@centos001 ~]# sudo chmod 750 /home/sopftpuser/ftp/upload
chmod: cannot access ‘/home/sopftpuser/ftp/upload’: No such file or directory
[root@centos001 ~]# sudo chmod 750 /home/sopftpuser/ftp
[root@centos001 ~]# sudo chown -R sopftpuser: /home/sopftpuser/ftp
[root@centos001 ~]# 

 

 

 

六、卸載(出錯了,你就卸載了在重新安裝,或者修改你的配置文件,此操作我做了多次,畢竟是萌新)

如果服務器上安裝了vsftpd,配置出錯需要卸載vsftpd

 

rpm -aq vsftpd

卸載vsftpd

 

rpm -e vsftpd-3.0.3

 

#用rpm -e 查找結果 進行刪除就ok了。

 

 warning: /etc/vsftpd/user_list saved as /etc/vsftpd/user_list.rpmsave
 warning: /etc/vsftpd/ftpusers saved as /etc/vsftpd/ftpusers.rpmsave #刪除時將備份vsftp的用戶列表文件。

 

 

 

七、結論

您學習了如何在CentOS 7系統上安裝和配置安全,輸入用戶名和密碼,登錄FTP

八、相關資料

》查看https://linuxize.com/post/how-to-setup-ftp-server-with-vsftpd-on-centos-7/,本文大部分是參看它的介紹,

但是在此基礎上做了增加,但是其中遇到了很多的坑,哎

》查看http://www.jsfhjj.com/sopcce/p/10743359.html 本文介紹了配置文件,

包括特別多,對ftp 訪問的授權,訪問的目錄等,還在慢慢看中

 

 解決: 

setenforce: SELinux is disabled

 

那么說明selinux已經被徹底的關閉了

 

如果需要重新開啟selinux,請按下面步驟:

 

vi /etc/selinux/config

 

更改為:SELINUX=1

 

必須重啟linux,不重啟是沒辦法立刻開啟selinux的

 

關閉

 

1 命令查看出selinux的狀態 

sestatus -v 

2 臨時關閉 selinux 

setenforce 0 

3 永久關閉selinux 

vi /etc/sysconfig/selinux 

把里邊的一行改為 

SELINUX=disabled

 

setenforce 1 設置SELinux 成為enforcing模式 

setenforce 0 設置SELinux 成為permissive模式 

如果要徹底禁用SELinux 需要在/etc/sysconfig/selinux中設置參數selinux=0
