  CentOS是Linux发行版之一,已经发布多个版本,那么你知道你使用的CentOS是哪个版本的吗?



有以下命令可以查看

# lsb_release -a
LSB Version: :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch
Distributor ID: CentOS
Description: CentOS release 5.4 (Final)
Release: 5.4
Codename: Final


这个命令适用于所有的linux,包括Redhat、SuSE、Debian、Centos等发行版。

root@MyMail ~ # uname
Linux
root@MyMail ~ # uname -r
2.6.18-164.el5
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux


以下二种方法适用于RedHat,CentOS

root@MyMail ~ # cat /etc/redhat-release
CentOS release 5.4 (Final)

登录到linux执行rpm -q redhat-release

#rpm -q redhat-release
或CentOS

root@MyMail ~ # rpm -q centos-release
centos-release-5-4.el5.centos.1


当前centos 版本与redhat对应的版本的命令
# cat /proc/version
Linux version 2.6.9-78.ELsmp (mockbuild@builder16.centos.) (g version 3.4.6 20060404 (Red Hat 3.4.6-10)) #1 SMP Fri Jul 25 00:04:28 EDT 2008

  方法

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

  Linux version 2.6.18-194.el5 (mockbuild@builder10.centos.) (g 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) 列出所有版本信息,

  [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

  注这个命令适用于所有的linux,包括RedHat、SUSE、Debian等发行版。

  2) 执行cat /etc/issue,例如如下

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

  CentOS release 5.5 (Final)

  Kernel r on an m

  3) 执行cat /etc/redhat-release ,例如如下

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

  CentOS release 5.5 (Final)

  查看系统是64位还是32位

  1、getconf LONG_BIT or getconf WORD_BIT

  [root@localhost ~]# getconf LONG_BIT

  64

  2、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

  3、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)

  Release 5.5

  Codename Final

  4、或者是使用查看文件的方法。

  vim /ect/issue

  上面就是查看CentOS版本信息的介绍了,除了能够知道你使用的是哪个版本外,还能够查看你所使用的CentOS系统是32位还是64位的。
