1. edit /etc/vsftpd.conf:
listen=YES
anonymous_enable=YES
local_enable=YES
write_enable=YES
local_umask=022
anon_upload_enable=YES
anon_mkdir_write_enable=YES
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
chown_uploads=YES
chown_username=honzeland
ftpd_banner=Welcome to blah FTP service.
secure_chroot_dir=/var/run/vsftpd
pam_service_name=vsftpd
rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
anon_root=/home/ftp
2. Now we must make writable directory for anonymous user.
cd /home/ftp
sudo mkdir opendir
sudo chmod 777 opendir/
Note: 采用proftp作server，安裝配置更容易
