Linux如何查看系统信息
转载自：http://flysky815.blog.163.com/blog/static/92692001201023183220409/

拿到一个系统，肯定要看看系统配置，linux下看配置，可没有windows那么直观。你只能一个一个查看。

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：内存

[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位数(32 or 64)

[root@srv /]# getconf LONG_BIT

32

四：查看linux版本

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

CentOS release 5 (Final)

[root@srv /]# more /etc/issue

CentOS release 5 (Final)

Kernel \r on an \m

[root@srv /]# more /proc/version

Linux version 2.6.18-92.1.18.el5.028stab060.2PAE ([email=root@rhel5-32-build-xemul]root@rhel5-32-build-xemul[/email]) (gc

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

五：查看内核版本

[root@srv /]# uname -r

2.6.18-92.1.18.el5.028stab060.2PAE

[root@srv /]# uname -a

Linux srv.eddiechen.cn 2.6.18-92.1.18.el5.028stab060.2PAE #1 SMP Tue Jan 13 12:31:30 MSK 2009 i686 i686 i386 GNU/Linux

六：查看时区

[root@srv /]# date -R

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

[root@srv /]#
