(轉)Linux下獲取軟硬件配置

一：cpu

[root@srv /]# more /proc/cpuinfo | grep "model name"

model name    : Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

model name    : Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

model name    : Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

model name    : Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

[root@srv /]# grep "model name" /proc/cpuinfo

model name    : Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

model name    : Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

model name    : Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

model name    : Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

[root@srv /]# grep "model name" /proc/cpuinfo | cut -f2 -d:

Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

Intel(R) Xeon(R) CPU          X3220 @ 2.40GHz

二：內存

[root@srv /]# grep MemTotal /proc/meminfo

MemTotal:        614400 kB

[root@srv /]# free -m

                   total        used        free    shared     buffers    cached

Mem:          600       23       576           0           0           0

-/+ buffers/cache:       23       576

Swap:          0           0           0

[root@srv /]# free -m |grep "Mem" | awk '{print $2}'

600

三：查看CPU位數(32 or 64)

[root@srv /]# getconf LONG_BIT

32

四：查看linux版本

[root@srv /]# more /etc/redhat-release

c version 4.1.2 20071124 (Red Hat 4.1.2-42)) #1 SMP Tue Jan 13 12:31:30 MSK 2009

五：查看內核版本

[root@srv /]# uname -r

六：查看時區

[root@srv /]# date -R

Wed, 25 Feb 2009 02:20:50 +0000

[root@srv /]# mv /etc/localtime /etc/localtime.save

[root@srv /]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

[root@srv /]# date -R

Wed, 25 Feb 2009 10:24:26 +0800

七：主機名

查看主機名

[root@srv /]# hostname

www.ifuoo.com

修改主機名

[root@srv /]# cat /etc/sysconfig/network

八：查看selinux狀況

[root@srv /]# sestatus

SELinux status:                disabled

九：網絡

IP

[root@srv /]# ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}'

207.154.202.216

網關

[root@srv /]# cat /etc/sysconfig/network

NETWORKING="yes"

GATEWAY="192.0.2.1"

HOSTNAME="srv.eddiechen.cn"

dns

[root@srv /]# cat /etc/resolv.conf

nameserver 208.74.168.131

nameserver 208.74.168.132

nameserver 4.2.2.1

修改Host文件

[root@srv /]# cat /etc/hosts

十：已經安裝的軟件包

[root@srv /]# rpm -qa | wc -l

197

[root@srv /]# yum list installed | wc -l

198

十一：磁盤和分區

[root@srv /]# df -h

Filesystem          Size    Used          Avail Use    %    Mounted on

/dev/simfs              10G     353M              9.7G       4%    /

[root@srv /]# du -sh

353M

[root@srv /]# du /etc -sh

4.6M     /etc

九：查看鍵盤佈局
