本节分享的内容，用于在linux下查看linux版本、cpu、内存、内核、系统位数等。
1、查看linux版本：
复制代码 代码示例:
[root@172-1-1-168 ~]# uname -a
Linux 172-1-1-168.www.jb200.com 2.6.18-308.16.1.el5 #1 SMP Tue Oct 2 22:01:37 EDT 2012 i686 i686 i386 GNU/Linux
[root@172-1-1-168 ~]# uname -r
2.6.18-308.16.1.el5
2、查看CPU信息：
复制代码 代码示例:
[root@172-1-1-168 ~]# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Pentium(R) Dual-Core CPU E5800 @ 3.20GHz
stepping : 10
cpu MHz : 3192.069
cache size : 2048 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 13
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss nx lm constant_tsc up nonstop_tsc pni ssse3 cx16 lahf_lm [8]
bogomips : 6384.13
3、查看CPU位数：
复制代码 代码示例:
[root@172-1-1-168 ~]# getconf LONG_BIT
32
4、查看内存：
复制代码 代码示例:
[root@172-1-1-168 ~]# cat /proc/meminfo

5、查看centos版本
复制代码 代码示例:
[root@172-1-1-168 ~]# cat /etc/
redhat-release
CentOS release 5.8 (Final)
