　　Summary:
　　SELinux is preventing the ftp daemon from reading users home directories (./home).
　　Detailed Description:
　　SELinux has denied the ftp daemon access to users home directories (./home). Someone is attempting to login via your ftp daemon to a user account. If you only setup ftp to allow anonymous ftp, this could signal a intrusion attempt.
　　Allowing Access:
　　If you want ftp to allow users access to their home directories you need to turn on the ftp_home_dir boolean: "setsebool -P ftp_home_dir=1"
　　The following command will allow this access:
　　setsebool -P ftp_home_dir=1
　　按照其中描述，执行该命令：
　　[root@web ~]# setsebool -P ftp_home_dir=1

　　之后本地用户就可以用FTP登录该服务器了

===ftp===
//If you want to share files anonymously
chcon -R -t public_content_t /var/ftp
//If you want to setup a directory where you can upload files
chcon -t public_content_rw_t /var/ftp/pub
You must also turn on the boolean allow_ftpd_anon_write
setsebool -P allow_ftpd_anon_write=1
//If you are setting up this machine as a ftpd server and wish to allow users to access their home directorories
setsebool -P ftp_home_dir 1
//If you want to run ftpd as a daemon
setsebool -P ftpd_is_daemon 1
//You can disable SELinux protection for the ftpd daemon
setsebool -P ftpd_disable_trans 1
