macOS FTP服务器架设

vsftpd

macOS安装配置vsftpd

安装vsftpd

安装前查看下说明

➜  ~ brew info vsftpd
vsftpd: stable 3.0.3 (bottled)
Secure FTP server for UNIX
https://security.appspot.com/vsftpd.html
Not installed
From: https://mirrors.ustc.edu.cn/homebrew-core.git/Formula/vsftpd.rb
==> Caveats
To use chroot, vsftpd requires root privileges, so you will need to run
`sudo vsftpd`.
You should be certain that you trust any software you grant root privileges.

The vsftpd.conf file must be owned by root or vsftpd will refuse to start:
  sudo chown root /usr/local/etc/vsftpd.conf

To have launchd start vsftpd now and restart at startup:
  sudo brew services start vsftpd
Or, if you don't want/need a background service you can just run:
  sudo vsftpd

brew install vsftpd

brew install vsftpd

查看文件都安装到了哪里

➜  ~ brew list vsftpd
/usr/local/Cellar/vsftpd/3.0.3/.bottle/etc/vsftpd.conf
/usr/local/Cellar/vsftpd/3.0.3/homebrew.mxcl.vsftpd.plist
/usr/local/Cellar/vsftpd/3.0.3/sbin/vsftpd
/usr/local/Cellar/vsftpd/3.0.3/share/man/ (2 files)

修改vsftpd配置文件 : /usr/local/etc/vsftpd.conf

查看下初始默认配置grep -v "#" /usr/local/etc/vsftpd.conf

anonymous_enable=YES
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
listen=YES

创建ftp文件夹

➜  /var sudo mkdir /var/ftp
➜  /var stat /var/ftp
16777220 38247940 drwxr-xr-x 2 root wheel 0 64 "Jan  4 12:55:32 2021" "Jan  4 12:55:32 2021" "Jan  4 12:55:32 2021" "Jan  4 12:55:32 2021" 4

将ftp文件夹配置为匿名登录的默认文件夹

anon_root=/var/ftp

经过实际操纵，匿名用户无法对根目录完成读写，根目录下创建专用文件夹，并赋予写权限

sudo mkdir /var/ftp/data
sudo chmod a+w /var/ftp/data

匿名登录+具备读写权限

修改配置

最终匿名读写的配置

➜  ~ grep -v "#" /usr/local/etc/vsftpd.conf
anonymous_enable=YES

write_enable=YES
anon_root=/var/ftp
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
listen=YES

测试：手动启动vsftpd

#修正文件权限
➜  ~ sudo chown root /usr/local/etc/vsftpd.conf
➜  ~ sudo /usr/local/Cellar/vsftpd/3.0.3/sbin/vsftpd  /usr/local/etc/vsftpd.conf
