CentOS查看內核版本，位數，版本號

1)[root@localhost ~]# cat /proc/version

Linux version 2.6.18-194.el5 (mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)) #1 SMP Fri Apr 2 14:58:14 EDT 2010

2)

[root@localhost ~]# uname -a

Linux localhost.localdomain 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:14 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

3)

[root@localhost ~]# uname -r

2.6.18-194.el5

2. 查看linux版本：

1) 列出全部版本信息,

[root@localhost ~]# lsb_release -a

LSB Version:    :core-3.1-amd64:core-3.1-ia32:core-3.1-noarch:graphics-3.1-amd64:graphics-3.1-ia32:graphics-3.1-noarch

Distributor ID: CentOS

Description:    CentOS release 5.5 (Final)

Release:        5.5

Codename:       Final

注:這個命令適用於全部的linux，包括Redhat、SuSE、Debian等發行版。

2) 執行cat /etc/issue,例如以下:

[root@localhost ~]# cat /etc/issue

CentOS release 5.5 (Final)

Kernel r on an m

3) 執行cat /etc/redhat-release ,例如以下:

[root@localhost ~]# cat /etc/redhat-release

CentOS release 5.5 (Final)

查看系統是64位仍是32位:

一、getconf LONG_BIT or getconf WORD_BIT

[root@localhost ~]# getconf LONG_BIT

64

二、file /bin/ls

[root@localhost ~]# file /bin/ls

/bin/ls: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped

三、lsb_release  -a

[root@localhost ~]# lsb_release -a

LSB Version:    :core-3.1-amd64:core-3.1-ia32:core-3.1-noarch:graphics-3.1-amd64:graphics-3.1-ia32:graphics-3.1-noarch

Distributor ID: CentOS

Description:    CentOS release 5.5 (Final)
