在vps主机上使用磁盘配额限制vsFTPd用户的空间大小

概述：在上一篇在vps主机安装vsFTPd文件服务器 构建ftp帐号后，但是vsFTPd不支持磁盘配额，这样就很不方便给朋友分配网页空间，那么可以使用linux系统自动的磁盘配额功能，给特定的帐号分配磁盘使用大小。

环境：centos5 特惠型vps

目的：给帐号vsftptest进行磁盘配额设置，此用户共有50M磁盘空间（不考虑inode),并且最低限制为45MB，宽限时间设置为1天

步骤：

1）使用eduota编辑用户可用的空间

[root@www ~]# edquota -u vsftptest
Disk quotas for user vsftptest (uid 500):
 Filesystem                   blocks       soft       hard     inodes     soft     hard
 /dev/simfs                       20       45000      50000          5        0        0

2)设置宽限时间

[root@www ~]# edquota -t
Grace period before enforcing soft limits for users:
Time units may be: days, hours, minutes, or seconds
 Filesystem             Block grace period     Inode grace period
 /dev/simfs                 1days               0seconds

3）输出quota报告

[root@www ~]# repquota -avug
