<p><strong>配置系统的磁盘配额支持</strong></p>
|

<p>首先，磁盘配额是区域性的，我们可以决定哪块分区进行磁盘配额，哪块分区不用（自然也就不用配置了）。一般而言，作为一台web虚拟主机服务器，<code>/home</code>和<code>/www</code>（或者类似的）是供用户存放资源的分区，所以可以对这两个分区进行磁盘配额。假定我们需要对<code>/home</code>分区实现用户级的限制，而对<code>/www</code>进行每个组的用户配额。</p>

<p>说明：<code>/etc/fstab</code>文件的每一行由六个字段组成：</p>

<ul>

<li>第一个字段：文件系统（分区）的注释（类似卷标）；</li>

<li>第二个字段：文件系统的装载点；</li>

<li>第三个字段：文件系统类型（磁盘配额只能在ext2文件系统上实现）；</li>
|
||
<li>第四个字段：装载文件系统是使用的选项，如果只想实现基于用户的磁盘配额，就加入usrquota关键字，只想实现基于组的磁盘配额，就加入grpqouta关键字，如果两者都需要，就全写入，中间可以用逗号分隔。</li>
|

<p>如果单用户模式报错的话umount你的设备<code>/dev/hda*</code></p>
|
||
<p>再执行就ok了，重启动系统，如果一切正常的话，quota将开始正常工作。</p>
|
||
<p><strong>设置用户和组配额的分配量</strong></p>
|
||
<p>对磁盘配额的限制一般是从一个用户占用磁盘大小和所有文件的数量两个方面来进行的。在具体操作之前，我们先了解一下磁盘配额的两个基本概念：软限制和硬限制。</p>
|
||
<ul>
|
||
<li>软限制：一个用户在文件系统可拥有的最大磁盘空间和最多文件数量，在某个宽限期内可以暂时超过这个限制。</li>
|
||
<li>硬限制：一个用户可拥有的磁盘空间或文件的绝对数量，绝对不允许超过这个限制。</li>
|
||
</ul>
|
||
<p><strong>通过edquota直接编辑数据文件：</strong></p>
|
||
<p>使用编辑配额命令edquota为用户配置定额，在重新启动系统之后，我们假设lanf是需要定额的系统帐户，可以使用如下命令来为用户分配磁盘配额：</p>

<p>这表示除了相应的容量的限制外，还对文件/目录的数量做了12800个的软限制和51200个的硬限制。在保存了新的配置后，该用户的磁盘使用就不能超过硬限制。如果用户试图超过这个限制，该操作将被取消，然后得到一个错误信息。但是，如果每个用户都要这么麻烦的设置的话，那这种重复的体力劳动实在有点令人不寒而栗，而且也太浪费时间了。幸好edquota还有个-p参数（prototype）可以对已有的用户设置进行拷贝。例如，我们想对Jack、Tom、Chen三个用户使用和lanf一样的限额配置，可以使用如下的命令：</p>
