Linux环境下查看服务器硬件信息 怎样 查看CPU型号 cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c 16 Intel(R) Xeon(R) CPU X5560 2.80GHz 怎样 查看物理CPU个数 cat /proc/cpuinfo | grep physical | uniq -c 1 physical id : 1 1 physical id : 0 查看CPU运行模式：32位或者64位，如果是32位的话并不代表不能运行在64位下 getconf LONG_BIT 64 查看是否CPU支持64位系统，如果值大于0，则支持64位运算，lm指long mode cat /proc/cpuinfo | grep flags | grep lm | wc -l 16 查看内存信息 cat /proc/meminfo MemTotal: 74175052 kB MemFree: 4242856 kB Buffers: 675664 kB Cached: 65423884 kB SwapCached: 16 kB Active: 46231212 kB Inactive: 20719936 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 74175052 kB LowFree: 4242856 kB SwapTotal: 75778596 kB SwapFree: 75778384 kB Dirty: 60 kB Writeback: 0 kB AnonPages: 851416 kB Mapped: 12422988 kB Slab: 1495940 kB PageTables: 1372180 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 112866120 kB Committed_AS: 21125340 kB VmallocTotal: 34359738367 kB VmallocUsed: 299916 kB VmallocChunk: 34359438111 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 Hugepagesize: 2048 kB 查看当前系统内核信息 uname -a Linux HOSTNAME 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux 查看当前操作系统内核信息 cat /etc/issue | grep Linux Red Hat Enterprise Linux Server release 5.4 (Tikanga) 查看服务器型号 dmidecode | grep Product Name Product Name: PowerEdge R710 Product Name: 0VWN1R 查看网卡信息 dmesg | grep -i eth Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v1.9.3 (March 17, 2009) eth0: Broadcom NetXtreme II BCM5709 1000Base-T (C0) PCI Express found at mem d6000000, IRQ 106, node addr a4badb28c33d eth1: Broadcom NetXtreme II BCM5709 1000Base-T (C0) PCI Express found at mem d8000000, IRQ 114, node addr a4badb28c33f eth2: Broadcom NetXtreme II BCM5709 1000Base-T (C0) PCI Express found at mem da000000, IRQ 122, node addr a4badb28c341 eth3: Broadcom NetXtreme II BCM5709 1000Base-T (C0) PCI Express found at mem dc000000, IRQ 130, node addr a4badb28c343 cnic: Added CNIC device: eth0 cnic: Added CNIC device: eth1 cnic: Added CNIC device: eth2 cnic: Added CNIC device: eth3 bnx2: eth0: using MSIX ADDRCONF(NETDEV_UP): eth0: link is not ready bnx2i: iSCSI not supported, dev=eth0 bnx2i: iSCSI not supported, dev=eth0 bnx2: eth0 NIC Copper Link is Up, 1000 Mbps full duplex ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready eth0: no IPv6 routers present process sysctl is using deprecated sysctl (syscall) net.ipv6.neigh.eth0.base_reachable_time; Usenet.ipv6.neigh.eth0.base_reachable_time_ms instead.linux下查看硬件信息的指令，比如top，free等，还可以通过内核文件来看，比如/proc/cpuinfo,/proc/meminfo等，还有一个指令给大家介绍怎么查看硬件信息-dmidecode, 希望对大家有点用处，认为我说的比较肤浅的，也不要拍砖，目的在于大家相互交流嘛。dmidecode是读取DMI的信息显示给大家的。rootmail proc# dmidecode -helpUsage: dmidecode OPTIONSOptions are:-d, -dev-mem FILE Read memory from device FILE (default: /dev/mem)-h, -help Display this help text and exit-q, -quiet Less verbose output-s, -string KEYWORD Only display the value of the given DMI string-t, -type TYPE Only display the entries of given type-u, -dump Do not decode the entries-V, -version Display the version and exit以上是它的帮助信息，最有用的当然是参数-t了，它后面可跟的参数有：0 BIOS1 System2 Base Board3 Chassis4 Processor5 Memory Controller6 Memory Module7 Cache8 Port Connector9 System Slots10 On Board Devices11 OEM Strings12 System Configuration Options13 BIOS Language14 Group Associations15 System Event Log16 Physical Memory Array17 Memory Device18 32-bit Memory Error19 Memory Array Mapped Address20 Memory Device Mapped Address21 Built-in Pointing Device22 Portable Battery23 System Reset24 Hardware Security25 System Power Controls26 Voltage Probe27 Cooling Device28 Temperature Probe29 Electrical Current Probe30 Out-of-band Remote Access31 Boot Integrity Services32 System Boot33 64-bit Memory Error34 Management Device35 Management Device Component36 Management Device Threshold Data37 Memory Channel38 IPMI Device39 Power Supply类型归纳一下如下：bios 0, 13system 1, 12, 15, 23, 32baseboard 2, 10chassis 3processor 4memory
