查看linux硬件信息大全
1, 主板信息
.查看主板的序列号
--------------------------------------------------
#使用命令
dmidecode|grep-i'serialnumber'
#查看板卡信息
cat/proc/pci
--------------------------------------------------
2,cpu信息
--------------------------------------------------
#通过/proc文件系统
1)cat/proc/cpuinfo
#通过查看开机信息
2)dmesg|grep-i'cpu'
#
3)dmidecode-tprocessor
一、CPU大小[root@idc~]#cat/proc/cpuinfo|grep"modelname"&&cat/proc/cpuinfo|grep"physicalid"
modelname:Intel(R)Xeon(TM)CPU2.80GHz
modelname:Intel(R)Xeon(TM)CPU2.80GHz
modelname:Intel(R)Xeon(TM)CPU2.80GHz
modelname:Intel(R)Xeon(TM)CPU2.80GHz
physicalid:0
physicalid:0
physicalid:3
physicalid:3
[root@idc~]#
说明：Linux下可以在/proc/cpuinfo中看到每个cpu的详细信息。但是对于双核的cpu，在cpuinfo中会看到两个cpu。常常会让人误以为是两个单核的cpu。
其实应该通过PhysicalProcessorID来区分单核和双核。而PhysicalProcessorID可以从cpuinfo或者dmesg中找到.
flags如果有ht说明支持超线程技术
判断物理CPU的个数可以查看physicalid的值，相同则为同一个物理CPU
可以看到上面，这台机器有两个双核的CPU，ID分别是0和3，大小是2.8G。
二、内存大小
[root@xbidc~]#cat/proc/meminfo|grepMemTotal
MemTotal:1034612kB
[root@xbidc~]#
三、硬盘大小
[root@xbidc~]#fdisk-l|grepDisk
Disk /dev/sda: 300.0 GB, 300000000000 bytes--------------------------------------------------
3,硬盘信息
--------------------------------------------------
#查看分区情况
fdisk-l
#查看大小情况
df-h
#查看使用情况
du-h
#
hdparm-I/dev/sda
#
dmesg|grepsda
--------------------------------------------------
4,内存信息
--------------------------------------------------
1)cat/proc/meminfo
2)dmesg|grepmem
3)free-m
4)vmstat
5)dmidecode|grep-imem
--------------------------------------------------
5,网卡信息
--------------------------------------------------
1)dmesg|grep-i'eth'
2)cat/etc/sysconfig/hwconf|grep-ieth
3)lspci|grep-i'eth'
--------------------------------------------------
6,鼠标键盘和USB信息
查看键盘和鼠标：cat/proc/bus/input/devices
查看USB设备：cat/proc/bus/usb/devices
查看各设备的中断请求(IRQ):cat/proc/interrupts
7,显卡信息
--------------------------------------------------
1)lspci|grep-i'VGA'
2)dmesg|grep-i'VGA'
--------------------------------------------------
8,声卡信息
--------------------------------------------------
1)lspci|grep-i'VGA'
2)dmesg|grep-i'VGA'
--------------------------------------------------
7,其他命令
.用硬件检测程序kuduz探测新硬件：servicekudzustart(orrestart)
.dmesg(查看所有启动时检测到的硬件信息)
.lspci(显示外设信息,如usb，网卡等信息)
.cat/etc/sysconfig/hwconf
.mpstat
8,需要手动安装的工具
lshw,hwinfo,hal-device-manager
9,Solaris如何检测硬件参数
俺从别处发现了些有意思的东西：
