使用 vsftpd 控制 ftp 訪問
I had vsftpd set up such that I was able to upload files to a VPS I set up. The only problem is that I could not create directories. I set up vsftpd to disallow anonymous users, but allow virtual users to connect with their local credentials. At this point, the error message when I tried to create a folder changed from ‘550: Create directory failed’ (I’m paraphrasing) to ‘550: Permission denied’. root owns the /var/www folder, and user with which I was authenticating had read and execute permissions but not write, so it makes sense that I wouldn’t be able to create folders or files.
At this point I tried using chown and chmod to recursively change the group ownership to a group that my user was in and give my user write permission. This seemed to work at first - in the SSH session, I was able to cd to /var/www and create a new directory. However, when I tried to log in with my ftp client, I was now denied access.
What’s even weirder is when I checked /var/log/vsftpd.log, I see the following lines:
Mon Jan 5 00:03:25 2015 [pid 801] CONNECT: Client "73.53.82.111" Mon Jan 5 00:03:25 2015 [pid 800] [gradinafrica] OK LOGIN: Client "73.53.82.111"…even though the login doesn’t seem to work. What’s going on?
EDIT (more info): OS: Ubuntu 14.04 Architecture: Virtual private server (?)
當我設置伺服器時，我不允許以 root 身份登錄（如多個來源所建議的那樣）並設置了一個不同的使用者 - ‘gradinafrica’ - 我將其添加到 sudo 組中。我正在嘗試將此帳戶用於 ftp。我根本沒有使用過 sftp。
這是 vsftpd.conf 的內容（註釋省略）：
listen=YES anonymous_enable=NO local_enable=YES virtual_use_local_privs=YES anon_upload_enable=YES dirmessage_enable=YES use_localtime=YES xferlog_enable=YES connect_from_port_20=YES chroot_local_user=YES local_root=/var/www/ secure_chroot_dir=/var/run/vsftpd/empty pam_service_name=vsftpd rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
如果您需要在 /var/www/ 中獲得使用者帳戶的寫入權限，則特定使用者希望根據您的作業系統成為 apache 或 www-data 組的成員。
write_enable=YES僅當您添加了具有 Web 根目錄的使用者作為其主目錄時才使用此選項
allow_writeable_chroot=YES
