运行脚本后 输入 yes 就会自动安装

1. 删除ftp用户命令
[[email protected] configuration-file]#/usr/local/pureftpd/bin/pure-pw userdel ftpuser1  
2. 修改ftp用户密码
[[email protected] ~]# /usr/local/pureftpd/bin/pure-pw passwd ftpuser
[[email protected] ~]# /usr/local/pureftpd/bin/pure-pw mkdb   //执行上面的修改密码后 需要更新一下密码库

安装完后会把账号和密码输入到屏幕上，存到主目录下ftp.txt文件
