查看linux內核版本及操作系統版本的命令

一、查看內核版本命令：

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

Linux version 2.6.18-238.el5 ([e-mail])(gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)) #1 SMP Sun Dec 19 14:22:44 EST2010

• (2)[root@localhost~]# uname -r

2.6.18-238.el5

• (3)[root@localhost~]# uname -a

Linux SOR_SYS.99bill.com 2.6.18-238.el5 #1 SMP Sun Dec 19 14:22:44 EST2010 x86_64 x86_64 x86_64 GNU/Linux

二、查看linux版本：

• 1) 登錄到服務器執行 lsb_release -a ,即可列出所有版本信息,例如:

[root@localhost~]# 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 HatEnterprise Linux AS release 4 (Nahant Update 4)

Release: 4

Codename: NahantUpdate4

注:這個命令適用於所有的linux，包括Redhat、SuSE、Debian等發行版。

• 2) 登錄到linux執行cat /etc/issue,例如如下:

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

Red Hat Enterprise Linux Server release 5.6 (Tikanga)

Kernel \r on an \m

• 3) 登錄到linux執行cat/etc/redhat-release ,例如如下:

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

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

注:這種方式下可以直接看到具體的版本號，比如 AS4 Update 1

• 4)登錄到linux執行rpm -qredhat-release ,例如如下:

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

redhat-release-5Server-5.6.0.3

注:這種方式下可看到一個所謂的release號，比如上邊的例子是5

這個release號和實際的版本之間存在一定的對應關系，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)兩種方法只對Redhat Linux有效

• 5) [root@localhost~]#file /bin/bash

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

• 6) [root@localhost~]#file /bin/cat

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