# getsebool -a | grep ftp
发现 ftpd_disable_trans –> off 或者 ftp_home_dir–>off
2. 使用setsebool命令开启
# setsebool ftpd_disable_trans 1 或者 # setsebool ftp_home_dir 1
3. 查看当前状态是否是on的状态
# getsebool -a|grep ftp
此时 ftpd_disable_trans –> on 或者 ftp_home_dir–>on
4. 最后重启 # service vsftpd restart
rpm -aq vaftpd（查看是否存在ftp服务器）
rpm -e vsftpd-2.0.5-16.el5_5.1（删除ftp服务器）
