 nizhua:x:1005:1::/var/www/nizhua:/bin/nologin
 #用户名用nizhua所属组daemon FTP目录/var/www/nizhua 不允许登陆
 b.同步/etc/passwd和/etc/shadow文件
 pwconv

 passwd nizhua

 4.ServerType用standalone方式启动有错,不知道怎么改,用inetd方式正常启动
 解决方法:UseIPv6    选项设为   off

 5.重新启动服务
 /etc/init.d/proftpd stop
 /etc/init.d/proftpd start

6.错误：Failed binding to 0.0.0.0, port 21: Address already in use
原来用inetd 方式安装的，改为了standalone方式，启动时端口被占用了，启动服务失败。
解决方法是注释/etc/inetd.conf里面的inetd模式启动命令，如：
#ftp    stream  tcp     nowait  root    /usr/sbin/tcpd /usr/sbin/proftpd
