Linux查看服務器參數的方法

當Linux操作系統在運行的時候就會表征出各種各樣參數信息，這些參數對於開發者們來說是非常重要的，那么你知道Linux怎么查看服務器參數嗎？

下面我們就去看看Linux查看服務器參數的方法。

一、CPU大小

• [[e-mail] ~]# more /proc/cpuinfo
• 可以看到詳細內容或：
• [[e-mail] ~]# cat /proc/cpuinfo |grep "model name" && cat /proc/cpuinfo |grep "physical id"
• model name: Intel(R) Xeon(TM) CPU 2.80GHz model name: Intel(R) Xeon(TM) CPU 2.80GHz
• model name: Intel(R) Xeon(TM) CPU 2.80GHz model name: Intel(R) Xeon(TM) CPU 2.80GHz
• physical id : 0 physical id : 0 physical id : 3 physical id : 3
• [[e-mail] ~]#
• 說明：Linux下可以在/proc/cpuinfo中看到每個cpu的詳細信息。但是對於雙核的cpu，在cpuinfo中會看到兩個cpu。常常會讓人誤以為是兩個單核的cpu。
• 其實應該通過Physical Processor ID來區分單核和雙核。而Physical Processor ID可以從cpuinfo或者dmesg中找到.
• flags 如果有 ht 說明支持超線程技術判斷物理CPU的個數可以查看physical id 的值，相同則為同一個物理CPU 可以看到上面，
• 這台機器有兩個雙核的CPU，ID分別是0和3，大小是2.8G。
• 二、內存大小
• [[e-mail] ~]# cat /proc/meminfo |grep MemTotal
• MemTotal: 1034612 kB
• [[e-mail] ~]#
• 三、硬盤大小
• [[e-mail] ~]# fdisk -l |grep Disk
• Disk /dev/sda: 300.0 GB, 300000000000 bytes
• [[e-mail] ~]#

以上內容就關於Linux查看服務器參數的方法，想要學習的朋友們，趕快把Linux查看服務器參數的方法這篇文章收入囊中吧!
