篇一：linux下如何查看系统和内核版本

linux下如何查看系统和内核版本 1. 查看内核版本命令：

1) [root@q1test01 ~]# cat /proc/version

Linux version 2.6.9-22.ELsmp (bhcompile@crowe.devel.redhat.com) (gcc version 3.4.4 20050721 (Red Hat 3.4.4-2)) #1 SMP Mon Sep 19 18:00:54 EDT 2005

2) [root@q1test01 ~]# uname -a

Linux q1test01 2.6.9-22.ELsmp #1 SMP Mon Sep 19 18:00:54 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux

3) [root@q1test01 ~]# uname -r

2.6.9-22.ELsmp

2.查看linux的版本主要有三种方法：

1) 登录到服务器执行 lsb_release -a ，即可列出所有版本信息，例如：

[root@3.5.5Biz-46 ~]# lsb_release -a

LSB Version: 1.3

Distributor ID: RedHatEnterpriseAS

Description: Red Hat Enterprise Linux AS release 4 (Nahant Update 1)

Release: 4

Codename: NahantUpdate1

[root@3.5.5Biz-46 ~]#

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

2) 登录到linux执行cat /etc/redhat-release ，例如如下：

[root@3.5.5Biz-46 ~]# cat /etc/redhat-release

Red Hat Enterprise Linux AS release 4 (Nahant Update 1)

[root@3.5.5Biz-46 ~]#

这种方式下可以直接看到具体的版本号，比如 AS4 Update 1

3)登录到linux执行rpm -q redhat-release ，例如如下

[root@3.5.5Biz-46 ~]# rpm -q redhat-release

redhat-release-4AS-2.4

[root@3.5.5Biz-46 ~]#

这种方式下可看到一个所谓的release号，比如上边的例子是2.4 这个release号和实际的版本之间存在一定的对应关系，如下：

redhat-release-3AS-1 -> Redhat Enterprise Linux AS 3

redhat-release-3AS-7.4 -> Redhat Enterprise Linux AS 3 Update 4 redhat-release-4AS-2 -> Redhat Enterprise Linux AS 4

redhat-release-4AS-2.4 -> Redhat Enterprise Linux AS 4 Update 1 redhat-release-4AS-3 -> Redhat Enterprise Linux AS 4 Update 2 redhat-release-4AS-4.1 -> Redhat Enterprise Linux AS 4 Update 3 redhat-release-4AS-5.5 -> Redhat Enterprise Linux AS 4 Update 4

篇二：查看Linux系统版本命令大全

查看Linux系统版本命令大全

一.查看内核版本命令

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

Linux version 2.6.18-238.el5 (mockbuild@x86-012.build.bos.redhat.com) (gcc version 4.1.2 20080704 (Red Hat

4.1.2-50)) #1 SMP Sun Dec 19 14:22:44 EST 2010

[root@SOR_SYS ~]#

2)[root@SOR_SYS ~]# uname -r

2.6.18-238.el5

3)[root@SOR_SYS ~]# uname -a

Linux SOR_SYS.99bill.com 2.6.18-238.el5 #1 SMP Sun Dec 19 14:22:44 EST 2010 x86_64 x86_64x86_64 GNU/Linux

[root@SOR_SYS ~]#

二.查看linux版本

1) 登录到服务器执行lsb_release -a ,即可列出所有版本信息,例如:

[root@SOR_SYS ~]# lsb_release -a

LSB

Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch

Distributor ID: RedHatEnterpriseAS

Description: Red Hat Enterprise Linux AS release 4 (Nahant Update 4)

Release: 4

Codename: NahantUpdate4

[root@SOR_SYS ~]#

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

2) 登录到linux执行cat /etc/issue,例如如下:

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

Red Hat Enterprise Linux Server release 5.6 (Tikanga)

Kernel \r on an \m

[root@SOR_SYS ~]#

3) 登录到linux执行cat /etc/redhat-release ,例如如下:

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

Red Hat Enterprise Linux AS release 4 (Nahant Update 4)

[root@SOR_SYS ~]#

注:这种方式下可以直接看到具体的版本号，比如 AS4 Update 1

4)登录到linux执行rpm -q redhat-release ,例如如下:

[root@SOR_SYS ~]# rpm -q redhat-release

redhat-release-5Server-5.6.0.3

[root@SOR_SYS ~]#

注:这种方式下可看到一个所谓的release号，比如上边的例子是5

这个release号和实际的版本之间存在一定的对应关系，如下：

redhat-release-3AS-1 ->Redhat Enterprise Linux AS 3

redhat-release-3AS-7.4 ->Redhat Enterprise Linux AS 3 Update 4

redhat-release-4AS-2 ->Redhat Enterprise Linux AS 4

redhat-release-4AS-2.4 ->Redhat Enterprise Linux AS 4 Update 1

redhat-release-4AS-3 ->Redhat Enterprise Linux AS 4 Update 2

redhat-release-4AS-4.1 ->Redhat Enterprise Linux AS 4 Update 3

redhat-release-4AS-5.5 ->Redhat Enterprise Linux AS 4 Update 4

另:第3)、4)两种方法只对Redhat Linux有效

5) [root@SOR_SYS ~]# file /bin/bash

/bin/bash: 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

[root@SOR_SYS ~]#

6) [root@SOR_SYS ~]# file /bin/cat

/bin/cat: 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

[root@SOR_SYS ~]#

篇三：如何查看Linux版本号

如何查看Linux版本号

1、查看内核版本命令：

(1)cat /proc/version

[root@1731522 ~]# cat /proc/version

Linux version 2.6.18-308.el5 (mockbuild@x86-007.build.bos.redhat.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)) #1 SMP Fri Jan 27 17:17:51 EST 2012

(2)uname -a

[root@1731522 ~]# uname -a

Linux 1731522.gzonet.com 2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

(3)uname -r

[root@1731522 ~]# uname -r

2.6.18-308.el5

2、查看Linux版本命令：

(1)执行 lsb_release -a命令，即可列出当前系统所有版本信息：

注：这个命令适用于所有的Linux，包括Red Hat、CentOS、SUSE等发行版。

(2)执行cat /etc/issue，显示如下：

[root@1731522 ~]# cat /etc/issue

Red Hat Enterprise Linux Server release 5.8 (Tikanga)

Kernel \r on an \m

(3)执行cat /etc/redhat-release，显示如下：

[root@1731522 ~]# cat /etc/redhat-release

Red Hat Enterprise Linux Server release 5.8 (Tikanga)

注：这种方式下可以直接看到具体的版本号，比如 5.8 (Tikanga)

(4)执行rpm -q redhat-release，显示如下:

[root@1731522 ~]# rpm -q redhat-release

redhat-release-5Server-5.8.0.3

注：这种方式需要安装redhat-released包的情况下才可用，执行命令后会看到一个所谓的release号，比如上边的例子是5.8.0.3；这个release号和实际的版本之间存在一定的对应关系，如下：

redhat-release-4AS-5.5 -> Redhat Enterprise Linux AS 4 Update 4

redhat-release-5Server-5.5.0.2 -> Redhat Enterprise Linux Server 5 Update 5 redhat-release-5Server-5.8.0.3 -> Redhat Enterprise Linux Server 5 Update 8

补充说明：第(3)、(4)两种方法只对Red Hat Linux有效。
