vsftpd 具有多個目錄的單使用者
我希望能夠讓我的 ftp 使用者訪問多個目錄。
我有我的 vsftp 設置來使用虛擬使用者，每個使用者都有（或可以有）單獨的配置文件。
主要問題是伺服器上設置了許多虛擬主機，我想僅將訪問其中一些目錄的權限授予某些使用者，而所有其他使用者都可以訪問這些目錄。例如：
User1 -/var/www/vhost/domain1.com -/var/www/vhost/domain2.com -/var/www/vhost/domain3.com -/var/www/vhost/domain4.com User2 -/var/www/vhost/domain1.com -/var/www/vhost/domain4.com User3 -/var/www/vhost/domain2.com由於交叉，我不能只將虛擬主機放入單獨的主文件夾中。我還嘗試將虛擬主機目錄的符號連結創建到單獨的使用者主目錄中，但是由於使用者被鎖定到他們的主目錄，你無法關注他們
這是我的 vsftpd.config 文件的副本（本地伺服器，但設置相同）
# 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. #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 # # The target log file can be vsftpd_log_file or xferlog_file. # This depends on setting xferlog_std_format parameter 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 # # The name of log file when xferlog_enable=YES and xferlog_std_format=YES # WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log #xferlog_file=/var/log/xferlog # # Switches between logging into vsftpd_log_file and xferlog_file files. # NO writes to vsftpd_log_file, YES to xferlog_file xferlog_std_format=YES # # You may change the default value for timing out an idle session. #idle_session_timeout=600 # # You may change the default value for timing out a data connection. #data_connection_timeout=120 # # It is recommended that you define on your system a unique user which the # ftp server can use as a totally isolated and unprivileged user. #nopriv_user=ftpsecure # # Enable this and the server will recognise asynchronous ABOR requests. Not # recommended for security (the code is non-trivial). Not enabling it, # however, may confuse older FTP clients. #async_abor_enable=YES # # By default the server will pretend to allow ASCII mode but in fact ignore # the request. Turn on the below options to have the server actually do ASCII # mangling on files when in ASCII mode. # Beware that on some FTP servers, ASCII support allows a denial of service # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd # predicted this attack and has always been safe, reporting the size of the # raw file. # ASCII mangling is a horrible feature of the protocol. #ascii_upload_enable=YES #ascii_download_enable=YES # # You may fully customise the login banner string: #ftpd_banner=Welcome to blah FTP service. # # You may specify a file of disallowed anonymous e-mail addresses. Apparently # useful for combatting certain DoS attacks. #deny_email_enable=YES # (default follows) #banned_email_file=/etc/vsftpd/banned_emails # # You may specify an explicit list of local users to chroot() to their home # directory. If chroot_local_user is YES, then this list becomes a list of # users to NOT chroot(). chroot_local_user=YES chroot_list_enable=YES # (default follows) chroot_list_file=/etc/vsftpd/chroot_list # # You may activate the "-R" option to the builtin ls. This is disabled by # default to avoid remote users being able to cause excessive I/O on large # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume # the presence of the "-R" option, so there is a strong case for enabling it. #ls_recurse_enable=YES # # When "listen" directive is enabled, vsftpd runs in standalone mode and # listens on IPv4 sockets. This directive cannot be used in conjunction # with the listen_ipv6 directive. listen=YES # # This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6 # sockets, you must run two copies of vsftpd with two configuration files. # Make sure, that one of the listen options is commented !! #listen_ipv6=YES virtual_use_local_privs=YES user_sub_token=$USER local_root=/var/www/html/vu/$USER #hide_ids=YES guest_enable=YES guest_username=apache user_config_dir=/etc/vsftpd/vsftpd-user-conf pam_service_name=vsftpd.virtual userlist_enable=YES tcp_wrappers=YES pasv_enable=YES pasv_min_port=64000 pasv_max_port=64321 port_enable=YES pasv_address=10.0.0.81 pasv_addr_resolve=NO
今天早上我偶然發現了這個問題的解決方案，在我的搜尋中，我發現有幾個人在問同樣的問題，但沒有找到一個上帝的解決方案，我認為是在這里為Google員工添加它。
（如果有人知道更好的解決方案，請告訴我）
我在這裡找到的解決方案是將虛擬主機的目錄安裝在每個使用者各自的主目錄中，這允許訪問目錄，就好像它們是所述使用者主目錄的實際子目錄一樣
臨時掛載目錄
mkdir /home/ftp_user/www_dev #create directory to mount too mount --bind /var/www/dev/ /home/ftp_user/www_dev #mount the directory如果您希望擁有此設置權限，請創建要掛載到的目錄，然後添加一行到
/etc/fstab/var/www/dev /home/ftp_user/www_dev none bind 0 0希望這可以幫助某人
