kangle服务器不断有用户反映ftp不能登录，其实是ftp服务以及意外关闭的原因。
运行下这个服务pureftpd，然后设置成开机启动，重启服务器之后，就正常了
service pureftpd restart
chkconfig pureftpd on
如果ftp还是无法连接，提示“被拒绝”，
复制以下命令到SSH回车基本可解决
/vhs/pure-ftpd/sbin/pure-authd --daemonize -s /var/run/ftpd.sock -r /vhs/kangle/bin/pureftp_auth
/vhs/pure-ftpd/sbin/pure-ftpd --daemonize -lextauth:/var/run/ftpd.sock
如果仍不可以，尝试杀死ftp服务
killall -9 pure-authd
killall -9 pure-ftpd
或者创建编辑一个service
vi /etc/init.d/pureftpd
以下是service服务文件文件内容
#!/bin/bash
#

重启ftp服务
service pureftpd restart
