ftp：550 failed to open file
今天在安装vsftpd以后做限制实体用户的总下载流量的测试，选择了本机测试。将一个名为taddm.zip的文件放在apachetest用户的主目录下，然后用root执行ftp localhost，并输入apachetest的账号与密码，接下来get这个taddm.zip文件，发现报错如下：ftp> get taddm.zip
local: taddm.zip remote: taddm.zip
200 PORT command successful. Consider using PASV.
550 Failed to open file.
ftp> bye
各种尝试后，在鸟哥那本书里面找到一种方法：
#getsebool -a |grep ftp
allow_ftpd_anon_write --> off
allow_ftpd_full_access --> off
allow_ftpd_use_cifs --> off
allow_ftpd_use_nfs --> off
allow_tftp_anon_write --> off
ftp_home_dir --> off 就是这个，需要设置为on才可以
ftpd_connect_db --> off
ftpd_disable_trans --> off
ftpd_is_daemon --> on
ftpd_use_fusefs --> off
httpd_enable_ftp_server --> off
tftpd_disable_trans --> off
接下来使用# setsebool -P ftp_home_dir=1
# getsebool -a|grep ftp
allow_ftpd_anon_write --> off
allow_ftpd_full_access --> off
allow_ftpd_use_cifs --> off
allow_ftpd_use_nfs --> off
allow_tftp_anon_write --> off
ftp_home_dir --> on
ftpd_connect_db --> off
ftpd_disable_trans --> off
ftpd_is_daemon --> on
ftpd_use_fusefs --> off
httpd_enable_ftp_server --> off
tftpd_disable_trans --> off
再使用get命令做测试，测试成功：
