**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][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\_64 x86\_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  
\[root@SOR\_SYS ~\]\#
