linux下查看各种硬件信息

监测硬件有没有被正确识别以及监控

首先是CPU型号线程数和主频
可以直接查看cpuinfo文件

cat /proc/cpuinfo

由于比较多所以过滤处理一下

cat /proc/cpuinfo|grep name|awk -F ':' '{print$2}'|uniq -c
2  Intel(R) Atom(TM) CPU D425   @ 1.80GHz

可以看到主频 型号和线程数

内存
同理可产看meminfo文件 只看总量和可用的话只需要取前两行

cat /proc/meminfo |head -2
MemTotal:        1912344 kB
MemFree:         1804808 kB

或者直接 free -m

free -m
total       used       free     shared    buffers     cached
Mem:          1867        102       1765          0          6         28
-/+ buffers/cache:         67       1800
Swap:         1999          0       1999

这里也可以看到交换的使用情况

物理硬盘
可以使用 fdisk -l

fdisk -l

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xbf4fbf4f

Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          26      204800   83  Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2              26         281     2048000   82  Linux swap / Solaris
Partition 2 does not end on cylinder boundary.
/dev/sda3             281        9730    75896832   83  Linux

可以看到硬盘和分区信息

显卡
显卡的话其实不重要了不过可以用lspci看到

lspci | grep "VGA"
00:02.0 VGA compatible controller: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller

同理这个命令可以看到主板设备和pci pcie设备 包括网卡声卡储存控制器等等

lspci

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller (rev 02)

最后温度的话可以使用lm_sensors查看
首先安装

yum install lm_sensors -y

然后第一次运行要先检测主板的传感器

sensors-detect

一路yes就行了 检测完之后会自动配置
之后执行sensors命令就能查看温度电压以及风扇转速信息了
