一、前言介紹
FTP（文件傳輸協議）是一種標准的客戶機-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服務器可用於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，並使用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守護進程並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並且查看狀態的
[root@centos001 ~]# sudo yum install vsftpd Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile base | 3.6 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 3.4 kB 00:00:00 packages-microsoft-com-prod | 2.9 kB 00:00:00 updates | 3.4 kB 00:00:00 Resolving Dependencies --> Running transaction check ---> Package vsftpd.x86_64 0:3.0.2-25.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================================================== Package Arch Version Repository Size =============================================================================================================================================== Installing: vsftpd x86_64 3.0.2-25.el7 base 171 k Transaction Summary =============================================================================================================================================== Install 1 Package Total download size: 171 k Installed size: 353 k Is this ok [y/d/N]: y Downloading packages: vsftpd-3.0.2-25.el7.x86_64.rpm | 171 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : vsftpd-3.0.2-25.el7.x86_64 1/1 Verifying : vsftpd-3.0.2-25.el7.x86_64 1/1 Installed: vsftpd.x86_64 0:3.0.2-25.el7 Complete!

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：https://www.cnblogs.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。
例如下圖，錯誤提示信息給出來了，你查看錯誤發現你輸入的信息也對，為啥有這個提示，
請相信你的PC，你輸入有問題，看下你的空格，空格，空格

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
[root@centos001 vsftpd]# systemctl status vsftpd.service
● vsftpd.service - Vsftpd ftp daemon

4、安裝FTP,測試
輸入、
yum install ftp
具體操作如下
[root@centos-7-06-64-20G ~]# yum install ftp Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package ftp.x86_64 0:0.17-67.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================================================== Package Arch Version Repository Size =============================================================================================================================================== Installing: ftp x86_64 0.17-67.el7 base 61 k Transaction Summary =============================================================================================================================================== Install 1 Package Total download size: 61 k Installed size: 96 k Is this ok [y/d/N]: y Downloading packages: ftp-0.17-67.el7.x86_64.rpm | 61 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : ftp-0.17-67.el7.x86_64 1/1 Verifying : ftp-0.17-67.el7.x86_64 1/1 Installed: ftp.x86_64 0:0.17-67.el7 Complete! [root@centos-7-06-64-20G ~]#
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目錄樹並設置正確的權限
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https://www.cnblogs.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
