如何查看linux服务器的版本和配置信息

inux下看配置，可没有windows那么直观。你只能一个一个查看。

一：cpu
[[email?protected] /]# more /proc/cpuinfo | grep "model
name"

[[email?protected] /]# grep "model name"
/proc/cpuinfo

二：内存
[[email?protected] /]# grep MemTotal /proc/meminfo

三：查看CPU位数(32 or 64)
[[email?protected] /]# getconf LONG_BIT
32
四：查看linux版本
[[email?protected] /]# more /etc/redhat-release
CentOS
release 5 (Final)
[[email?protected] /]# more /etc/issue
CentOS release 5 (Final)
Kernel r on an m

五：查看内核版本
[[email?protected] /]# uname
-r
2.6.18-92.1.18.el5.028stab060.2PAE
[[email?protected] /]# 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
[[email?protected] /]# date -R
Wed,25 Feb 2009

[[email?protected] /]# mv /etc/localtime
/etc/localtime.save
[[email?protected] /]# cp /usr/share/zoneinfo/Asia/Shanghai
/etc/localtime
[[email?protected] /]# date -R
Wed,25 Feb 2009
10:24:26 +0800
七：主机名
[[email?protected] /]# hostname
