linux下查看CPU.内存型号.pci 转自《Ivan-blog》
cat /proc/cpuinfo | grep 'physical id' physical id : 0 physical id : 0 physical id : 0 physical id : 0
如果physical id相同,表示这是一颗4核心的CPU
查看CPU的生产商和型号:
查看生产商:
cat /proc/cpuinfo | grep ‘vendor_id’
查看型号:
cat /proc/cpuinfo | grep ‘model name’
查看频率:
cat /proc/cpuinfo | grep ‘cpu MHz’
查看核心的数量:
cat /proc/cpuinfo | grep ‘cpu cores’
free -m total used free shared buffers cached Mem: 4048 1708 2339 0 164 1464 -/+ buffers/cache: 80 3967 Swap: 1983 0 1983
说明: -m参数,以M字节(megabytes)为单位查看内存大小,
上面的例子中我们可以看到,内存的总大小是4048M,也就是4G
想看到更详细的内存信息?

从上面我们可以看到有4条1G的内存被安装在前4条内存插槽上,而locator从DIMM5-DIMM8是空着的
前四条内存的型号为:Part Number: NT1GT72U8PB1BN-3C
生产商的ID是:Manufacturer: 830B8089830B
1,查看pci的相关信息
先解释一下概念:
什么是PCI
Peripheral Component Interconnect,外围设备互联,
它是计算机上面应用的设备总线(总线,就是bus,是传输数据信号的通道)
lspci
这个命令默认是已经安装的,
如找不到此命令,可以安装pciutils这个包
命令举例:
lspci 00:00.0 Host bridge: Intel Corporation 5000X Chipset Memory Controller Hub (rev 12) 00:02.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x4 Port 2 (rev 12) 00:03.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x4 Port 3 (rev 12) 00:04.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x8 Port 4-5 (rev 12) 00:05.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x4 Port 5 (rev 12) 00:06.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x8 Port 6-7 (rev 12) 00:07.0 PCI bridge: Intel Corporation 5000 Series Chipset PCI Express x4 Port 7 (rev 12) 00:10.0 Host bridge: Intel Corporation 5000 Series Chipset FSB Registers (rev 12) 00:10.1 Host bridge: Intel Corporation 5000 Series Chipset FSB Registers (rev 12) 00:10.2 Host bridge: Intel Corporation 5000 Series Chipset FSB Registers (rev 12) 00:11.0 Host bridge: Intel Corporation 5000 Series Chipset Reserved Registers (rev 12) 00:13.0 Host bridge: Intel Corporation 5000 Series Chipset Reserved Registers (rev 12) 00:15.0 Host bridge: Intel Corporation 5000 Series Chipset FBD Registers (rev 12) 00:16.0 Host bridge: Intel Corporation 5000 Series Chipset FBD Registers (rev 12) 00:1c.0 PCI bridge: Intel Corporation 631xESB/632xESB/3100 Chipset PCI Express Root Port 1 (rev 09) 00:1d.0 USB Controller: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #1 (rev 09) 00:1d.1 USB Controller: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #2 (rev 09) 00:1d.2 USB Controller: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #3 (rev 09) 00:1d.3 USB Controller: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #4 (rev 09) 00:1d.7 USB Controller: Intel Corporation 631xESB/632xESB/3100 Chipset EHCI USB2 Controller (rev 09) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev d9) 00:1f.0 ISA bridge: Intel Corporation 631xESB/632xESB/3100 Chipset LPC Interface Controller (rev 09) 00:1f.1 IDE interface: Intel Corporation 631xESB/632xESB IDE Controller (rev 09) 01:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08) 02:00.0 PCI bridge: Broadcom EPB PCI-Express to PCI-X Bridge (rev c3) 03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) 04:00.0 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express Upstream Port (rev 01) 04:00.3 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express to PCI-X Bridge (rev 01) 05:00.0 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express Downstream Port E1 (rev 01) 05:01.0 PCI bridge: Intel Corporation 6311ESB/6321ESB PCI Express Downstream Port E2 (rev 01) 06:00.0 PCI bridge: Broadcom EPB PCI-Express to PCI-X Bridge (rev c3) 07:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) 0e:0d.0 VGA compatible controller: ATI Technologies Inc ES1000 (rev 02)
从中看到的信息:Ethernet controller:这个是网卡
VGA compatible controller:这个是显卡
USB Controller: USB控制器
SCSI storage controller: SCSI的存储控制器
说明:如果你感觉这份信息还不够详细,
那么可以在后面添加参数,有3个参数可以使用:
lspci -v verbose 详细
lspci -vv very verbose 很详细
lspci -vvv even more verbose 更详细
以树结构来显示pci总线:
lspci -tv
