1、前言
ftp搭建需求
2、创建文件夹
cd /home/bjlthy
mkdir ftp
chmod 777 ftp/
3、安装
sudo apt-get remove vsftpd
sudo rm /etc/pam.d/vsftpd
sudo apt-get install vsftpd
3、ftp配置
sudo vim /etc/vsftpd.conf
后面直接追加以下内容
anonymous_enable=YES
write_enable=YES
anon_upload_enable=YES
anon_world_readable_only=NO
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list
utf8_filesystem=YES
local_root=/home/bjlthy/ftp
seccomp_sandbox=NO
sudo vim /etc/vsftpd.chroot_list
root
bjlthy
ftp
4、重启
sudo /etc/init.d/vsftpd restart
ps -ef | grep ftp
使用FTP工具连接成功

6、参考
匿名权限控制
anonymous_enable=YES #是否启用匿名用户
no_anon_password=YES #匿名用户login时不询问口令
下面这四个主要语句控制这文件和文件夹的上传、下载、创建、删除和重命名。
anon_upload_enable=（yes/no)； #控制匿名用户对文件（非目录）上传权限。#YES表示匿名用户可以上传
anon_world_readable_only=（yes/no）； #控制匿名用户对文件的下载权限 #NO表示匿名用户可以下载
anon_mkdir_write_enable=（yes/no）； #控制匿名用户对文件夹的创建权限 #YES
anon_other_write_enable=（yes/no）； #控制匿名用户对文件和文件夹的删除和重命名 #YES
