上传
使用xftp客户端上传文件，如图所示
此时上传状态报错，查看详情
从错误看出是应为无法创建文件造成的。那么我们就要修改ftp服务器的配置了。
授权
chmod 755 /opt/test_ftp // 给予文件夹的操作权限
一般创建一个ftp 用户，作为管理员只希望它只能访问其自己的所属目录的，是不会让他选择其他目录的。
设置ftp用户的权限
在安装好ftp时，在 /etc/vsftpd目录下可以看到vsftpd的配置文件vsftpd.conf
进入目录
cd /etc/vsftpd
查看列表
ls
编辑配置文件
vi vsftpd.conf
将用户(一般指虚拟用户)限制在自家目录
修改配置文件中,这样用户就只能访问自己家的目录了:
chroot_local_user=yes
重启ftp
service vsftpd restart
使用xftp客户端，进行尝试。

#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.

# You may fully customise the login banner string:

# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of

# You may activate the "-R" option to the builtin ls. This is disabled by

anon_other_write_enable=YES

设置权限
使用命令
getsebool -a|grep ftp
getsebool，列出所有selinux bool数值清单列表与内容。
allow_ftpd_anon_write --> onallow_ftpd_full_access --> off
开启 anon_write 和full_access
setsebool allow_ftpd_anon_write 1
etsebool allow_ftpd_full_access 1
重启ftp服务
service vsftpd restart
测试
在本地使用xftp客户端进行上传，下载，删除，重命名，操作。如图
总结
设置权限，感觉只需配置文件中配置对了，然后将full_access 设置为1 就可以了。
