 VSFTP is an FTP server software for Unix-like systems released under the GPL. Its full name is Very Secure FTP, and as the name suggests, the developer’s primary focus was code security. The following procedure is demonstrated on CentOS 5. Install vsftp yum install vsftpd Create Log File touch /data1/logs/vsftpd.log Modify vsftp Configuration File vi /etc/vsftpd/vsftpd.conf Parameter Settings. Note: Type “/search term” to quickly find entries. Be careful not to introduce any extra spaces. anonymous_enable=NO #Disable anonymous access local_enable=YES #Allow local users to access chroot_list_enable=YES #Restrict users to their home directories xferlog_file=/var/log/vsftpd.log #Path for the vsftpd service log file; does not exist by default ascii_upload_enable=YES #Allow uploads ascii_download_enable=YES #Enable ASCII mode download support pam_service_name=vsftpd #Do not forget to add this Manually enter the following parameters and values guest_enable=YES #Enable virtual user functionality guest_username=ftp #The system user that virtual users map to user_config_dir=/etc/vsftpd/vuser_user Create chroot list touch /etc/vsftpd/list echo ftp>>/etc/vsftpd/list Perform authentication. If db_load is not found, install db4-utils first (yum install db4 db4-utils) vi /etc/vsftpd/vsftp_users.conf Enter odd lines as usernames and even lines as passwords www_lingdus_com #Username www_lingdus_com #Password Generate Authentication File db_load -T -t hash -f /etc/vsftpd/vsftp_users.conf /etc/vsftpd/vsftp_users.db Edit the PAM authentication file. Clear or comment out all existing content. vi /etc/pam.d/vsftpd After clearing the file, enter: auth required pam_userdb.so db=/etc/vsftpd/vsftp_users account required pam_userdb.so db=/etc/vsftpd/vsftp_users Customize User Settings mkdir /etc/vsftpd/users/ vi /etc/vsftpd/vuser_conf/www_lingdus_com Add the following content local_root=/data0/htdocs/lingdus/bbs #Its root directory write_enable=YES anon_umask=022 anon_world_readable_only=NO anon_upload_enable=YES anon_mkdir_write_enable=YES anon_other_write_enable=YES Done. Start or restart vsftp service vsftpd restart You can now connect to FTP IP: XXX.XXX.XXX.XXX Port: 21 Username: www_lingdus_com Password: www_lingdus_com If you encounter the error “553 Could not create file” or cannot upload when connecting to FTP, disable SELinux Terminal: setsebool -P ftpd_disable_trans 1 Restart: service vsftpd restart Alternatively, change guest_username=ftp #The system user that virtual users map to to guest_username=root #The system user that virtual users map to Restart: service vsftpd restart If you encounter the error “500 OOPS: bad bool value in config file for: XXX” when starting or connecting to FTP It is very likely that there are extra spaces in your parameter settings, or a parameter name is incorrect.
