搭建ftp服务器

1：首先，更新软件源，保证源是最新的，这样有利于下面在线通过apt-get install命令安装ftp。 2：使用sudo apt-get install vsftp命令安装vsftp，安装软件需要root权限，我们使用sudo来暂时获取。 3：安装好ftp后默认是会自动创建ftp用户的，然后我们设置ftp用户的密码，输入 4：sudo passwd ftp，然后输入密码，再确认密码。为 ftp用户创建的目录默认为/srv/ftp 5：对/etc/vsftpd.conf配置文件进行一定的修改。使用 sudo gedit /etc/vsftpd.conf打开配置文件。将配置文件中”anonymous_enable=YES （是否允许匿名ftp，若不允许选NO）取消如下配置前的注释符号： local_enable=YES（是否允许本地用户登录） 27行附近： #本地用户，liyafei ,密码 write_enable=YES（是否允许本地用户写的权限） 29行附近： chroot_local_user=YES（是否将所有用户限制在主目录） 121行附近： chroot_list_enable=YES（是否启动限制用户的名单） chroot_list_file=/etc/vsftpd.chroot_list（可在文件中设置多个账号） /*********************** /etc/vsftpd.conf ***************************/ # the user does not have write access to the top level directory within the # chroot) chroot_local_user=YES chroot_list_enable=YES # (default follows) chroot_list_file=/etc/vsftpd.chroot_list #chroot_list_file=/etc/chroot_list 然后重启ftp服务，使用命令sudo service vsftpd restart重启ftp服务

浏览器通过ftp://192.168.100.91访问成功该目录成功成功

通过filezilla进行上传文件

home目录下可以创建很多用户目录。对/etc/vsftpd.conf进行如下配置

userlist_deny=NO userlist_file=/etc/allowed_users seccomp_sandbox=NO local_root=/home/ftp

那么在/etc/allowed_users中的用户就可以通过用户名和密码登录到服务器访问/home/ftp

/etc/allowed_users 文件内容

user1 user2

那么 user1,user2 用户和本地用户就可以访问/home/ftp中的内容.

一般哪一个使用哪一个用户名，就访问哪一个用户的主目录，在home目录下面会为每一个用户创建一个目录。

浏览器默认使用ftp用户，访问srv/ftp目录下的内容。就算其它用户在浏览器登录了，也不行。除非将/srv/ftp 目录删除。

用filezilla客户端对文件进行上传，因为/home/ftp中的文件夹都没有写权限，所以进行上传时提示： 553 Could not create file

我们需要在/home/ftp文件夹下创建一个具有写权限的文件夹，例如创建文件夹write;

首先在ftp的目录中创建一个目录，然后设置权限为777 $ sudo mkdir /home/ftp/write $ sudo chmod -R 777 /home/ftp/write 然后修改vsftp的配置文件/etc/vsftpd.conf文件在最后添加上 local_root=/home/ftp #这是allowed_users 文件夹中的用户访问的路径，上面的配置文件，已经添加过保存，然后杀死vsftpd进程，然后重启vsftpd服务器程序。试试看，将文件上传到write目录，这个时候可以正常的上传文件了。

一定要将创建的目录权限修改为可写w，否则提示错误；

响应: 227 Entering Passive Mode (192,168,100,91,84,116). 命令: STOR 网站设计.docx 响应: 553 Could not create file. 错误: 严重文件传输错误

这时就可以向/home/ftp/write 文件夹中上传文件。

如果以user3用户登录，user3用户的目录又在/home/user3 下面，那么使用java客户端上传文件时，路径是从/home/user3开始的。不再加前面的/home/user3

bashPath=/home/usre3就可以省去。

// if (!ftp.changeWorkingDirectory(basePath+filePath)) { if (!ftp.changeWorkingDirectory(filePath)) {

同样，我们也可以在/srv/ftp文件夹中创建具有写权限的文件夹，供用户名为ftp的用户进行添加文件。

当想要加载其中的文件时，需要将文件目录所有者root改为使用的用户。 chown -hR liyafei:liyafei ./liyafei

总结：用户名ftp的用户访问/srv/ftp文件夹

本地用户和allowed_users中的用户访问指定的local_root文件夹

如果需要上传功能，需要在文件夹下创建具有写功能的文件夹

在html页面下载ftp服务器内容，通过在连接中指定用户名和密码，和与用户名密码对应的文件位置就可以下载。

例如：下载uftp用户下的/home/ftp/public/file/vsftpd.conf 文件。uftp用户对应的根目录为/home/ftp，如下所示

DOCTYPE html> Title 直接使用一个超链接： ftp://用户名：密码@ip:端口号/该用户下面的目录，省去 local_root 目录。点击FTP下载

配置文件：
