检查服务器上的RAM数量
检查服务器上的RAM数量
提问于 2011-10-25 20:51:56
是否有一种方法来检查服务器(而不是打开它并实际查看)框中的内存数量，即有多少插槽是空闲的。另外，我需要知道它可能需要多少公羊？
我知道我可以检查/proc/meminfo的RAM，但我真的更关心的是，有多少插槽是免费/占用的类型。也就是说，我需要知道我可以添加多少ram，以及添加到特定对象中的类型，但是我不知道如何去做。

另一个选项是lshw命令(手册页)-它提供了很多东西的输出，包括RAM插槽。整个输出非常长，但是sudo lshw -short给出了一个摘要，包括每个RAM插槽一行，无论插槽中是否有任何RAM。或者是关于内存的全部信息，但忽略了所有您可以做的sudo lshw -class memory。
我从sudo lshw -short获得的输出是：
