[贴教程]Linux下怎样查看机器配置啊？cpu/内存/硬盘

你说： (10:59:33)
dmesg | grep hd

[root@bj etc]# dmesg|grep hd
hdb: CD-224E, ATAPI CD/DVD-ROM drive
hdb: attached ide-cdrom driver.
hdb: ATAPI 24X CD-ROM drive, 128kB Cache
SCSI device sda: 71132959 512-byte hdwr sectors (36420 MB)

这是36G吧？
你说： (11:01:40)
是！

[root@bj etc]# dmesg|grep cpu
cpu_sibling_map[0] = 3
cpu_sibling_map[1] = 2
cpu_sibling_map[2] = 1
cpu_sibling_map[3] = 0
cpu: 0, clocks: 1328920, slice: 265784
cpu: 3, clocks: 1328920, slice: 265784
cpu: 1, clocks: 1328920, slice: 265784
cpu: 2, clocks: 1328920, slice: 265784

你说： (11:02:52)
# dmesg | grep proc
Detected 1804.140 MHz processor.

想查CPU有几个，什么型号的，类似这样的表述PIII800*2

看不懂
你说： (11:06:25)
Intel Xeon CPU 2.80GHz * 4

啊，不会吧，4个？

这个不是真正的CPU吧，是不是有虚拟的

这里记录的服务器记录从来没有4个的，最不会吧两个
你说： (11:08:30)
新Xeon有HyperThreding技术，如果有两个物理的处理器并打开HT功能后会有显示4个，你至少有两个

哦，好的，那就写两个吧！:P

怎样看系统版本啊？
你说： (11:10:47)
uname -a

[root@bj etc]# uname -a
Linux bj 2.4.25 #11 SMP Tue Mar 30 15:15:52 CST 2004 i686 i686 i386 GNU/Linux

这是什么版本，才linux2?
你说： (11:11:26)
Kernel 2.4.25 #11 SMP
你说： (11:11:55)
# dmesg | grep redhat
Linux version 2.4.18-3 (bhcompile@daffy.perf.redhat.com) (gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110)) #1 Thu Apr 18 07:37:53 EDT 2002
#

Linux version 2.4.25 (root@bj) (gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #11 SMP Tue Mar 30 15:15:5

这是redhat3。2。2 吗？这么低啊？
你说： (11:16:18)
? dmesg | more

嗯,就是dmesg查出来的
你说： (11:23:04)
查。。。。。。

不用查了，就写linux2.4.25好了，没错吧

Linux Kernel 2.4.25 #11 SMP
