Utilisez SpringBoot pour configurer le serveur FTP afin de télécharger, supprimer et télécharger des fichiers.
Vérifiez si vsftpd est installé
rpm -qa | grep vsftpd
Vérifiez si vsftpd a été installé et vérifiez le numéro de version.
Installez vsftpd
yum -y install vsftpd
Si une erreur est signalée, utilisez les privilèges d'administrateur pour exécutez
sudo yum -y install vsftpd
sudo yum -y install vsftpd
关闭匿名访问
关闭匿名访问后,想访问里面的文件就需要账号和密码;如果不关,就可以直接访问。
vim /etc/vsftpd/vsftpd.conf
如果提示是只读文件,那么你只需要输入命令:
sudo vim /etc/vsftpd/vsftpd.conf
如下:
# Example config file /etc/vsftpd/vsftpd.conf # # The default compiled in settings are fairly paranoid. This sample file # loosens things up a bit, to make the ftp daemon more usable. # Please see vsftpd.conf.5 for all compiled in defaults. # # READ THIS: This example file is NOT an exhaustive list of vsftpd options. # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's # capabilities. # # Allow anonymous FTP? (Beware - allowed by default if you comment this out). anonymous_enable=NO # # Uncomment this to allow local users to log in. local_enable=YES # # Uncomment this to enable any form of FTP write command. write_enable=YES # # Default umask for local users is 077. You may wish to change this to 022, # if your users expect that (022 is used by most other ftpd's) local_umask=022 # # Uncomment this to allow the anonymous FTP user to upload files. This only # has an effect if the above global write enable is activated. Also, you will # obviously need to create a directory writable by the FTP user. # When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access #anon_upload_enable=YES # # Uncomment this if you want the anonymous FTP user to be able to create # new directories. #anon_mkdir_write_enable=YES # # Activate directory messages - messages given to remote users when they # go into a certain directory. dirmessage_enable=YES # # Activate logging of uploads/downloads. xferlog_enable=YES # # Make sure PORT transfer connections originate from port 20 (ftp-data). connect_from_port_20=YES # # If you want, you can arrange for uploaded anonymous files to be owned by # a different user. Note! Using "root" for uploaded files is not # recommended! #chown_uploads=YES #chown_username=whoever # # You may override where the log file goes if you like. The default is shown # below. #xferlog_file=/var/log/xferlog # # If you want, you can have your log file in standard ftpd xferlog format. # Note that the default log file location is /var/log/xferlog in this case. xferlog_std_format=YES # # You may change the default value for timing out an idle session. #idle_session_timeout=600
关闭匿名访问就是将:anonymous_enable=NO
启动服务

看到绿色的
active(running)
,代表着启动成功正在运行中。
添加 FTP 用户
因为在 Linux 上,root 用户是不能登陆 FTP 的。如果你输入的是 root 用户,登陆会失败的。
adduser ftpadmin
设置密码:
passwd ftpadmin
输入两次密码就 ok 了。
配置允许root用户登录
将 /etc/vsftpd/user_list
文件和 /etc/vsftpd/ftpusers
文件中的root
这一行注释掉
修改/etc/vsftpd/vsftpd.conf
,在最后一行处添加local_root=/
service vsftpd restart
这样远程就可以root用户身份登录ftp了。
文件存储地址授权
如存储地址为:app/upload/
Après avoir désactivé l'accès anonyme, vous avez besoin d'un compte et d'un mot de passe pour accéder aux fichiers qu'il contient si vous ne l'activez pas ; éteint, vous pouvez y accéder directement.
chmod 777 /app/upload/
Si l'invite est un fichier en lecture seule, il vous suffit alors de saisir la commande : sudo vim /etc/vsftpd/vsftpd.conf
Comme suit :
<dependency> <groupId>com.jcraft</groupId> <artifactId>jsch</artifactId> <version>0.1.55</version> </dependency>
Pour désactivez l'accès anonyme, changez simplement : anonyme_enable =NO
