Centos7实现磁盘限额设置方法
<p>添加硬盘到虚拟机 并实现自动挂载 </p><p>
完成挂载硬盘后，开始以下步骤</p><p>
注意：需要在配置文件/etc/fstab，defaults 后面那加上usrquota和grpquota “，”隔开</p><p>

说明：第一个soft表示磁盘容量软限制 第二个soft表示文件个数软限制 ，第一个hard表示磁盘容量硬限制 第二个hard表示文件个数硬限制</p><p>
注意：只用修改这四个对应的参数，其他默认不动</p><p>
如：下面修改容量软限制为80M 容量硬限制为100M 文件个数软限制为2 文件个数硬限制为3 注意对齐 然后保存退出</p><div class="jb51code"><div><div class="syntaxhighlighterxhtml" id="highlighter_354718"><div class="toolbar">?</div><table border="0" cellpadding="0" cellspacing="0"><tbody><tr class="firstRow"><td class="gutter"><div class="line number1 index0 alt2">
