如何查看Linux系统使用的版本信息呢？ 下面这篇文章收集、整理了一些常见的查看Linux系统版本的方法。由于手头只有Oracle Linux、Centos Linux、Redhat Linux三个版本Linux，所以像Debian、Ubuntu之类的Linux系统,下面方法在这些版本都没测试过。

1：more /etc/issue 命令查看

1.1 Oracle Linux 

代码如下:

[root@DB-Server ~]# more /etc/issueOracle Linux Server release 5.7Kernel \r on an \m 

1.2 Centos Linux

 

代码如下:

[root@Centos2 ~]# more /etc/issueCentOS release 6.4 (Final)Kernel \r on an \m 

  

1.3 RedHat Linux

 

代码如下:

[root@getlnx05 ~]# more /etc/issueRed Hat Enterprise Linux Server release 5.7 (Tikanga)Kernel \r on an \m 

  

2: lsb_release -a 命令查看  

2.1 Oracle Linux 

代码如下:

[root@DB-Server ~]# 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: EnterpriseEnterpriseServer

Description: Enterprise Linux Enterprise Linux Server release 5.7 (Carthage)

Release: 5.7

Codename: Carthage

2.2 Centos Linux

代码如下:

[root@Centos2 ~]# lsb_release -a

LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

Distributor ID: CentOS

Description: CentOS release 6.4 (Final)

Release: 6.4

Codename: Final

2.3 RedHat Linux

代码如下:

[root@getlnx05 ~]# 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: RedHatEnterpriseServer

Description: Red Hat Enterprise Linux Server release 5.7 (Tikanga)

Release: 5.7

Codename: Tikanga

3：cat /etc/redhat-release 命令查看

这个命令应该只有部分Linux可以查看，不是所有版本Linux都可以使用该命令

3.1 Oracle Linux 

代码如下:

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

Red Hat Enterprise Linux Server release 5.7 (Tikanga)

[root@DB-Server etc]# cat /etc/*release

Enterprise Linux Enterprise Linux Server release 5.7 (Carthage)

Oracle Linux Server release 5.7

Red Hat Enterprise Linux Server release 5.7 (Tikanga)

[root@DB-Server etc]# ls /etc/*lease

/etc/enterprise-release /etc/oracle-release /etc/redhat-release

[root@DB-Server etc]# 

3.2 Centos Linux

代码如下:

[root@Centos2 ~]# cat /etc/redhat-release 

CentOS release 6.4 (Final)

[root@Centos2 ~]# cat /etc/*release

CentOS release 6.4 (Final)

LSB_VERSION=base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

CentOS release 6.4 (Final)

CentOS release 6.4 (Final)

[root@Centos2 ~]# ls /etc/*release

/etc/centos-release /etc/lsb-release /etc/redhat-release /etc/system-release

[root@Centos2 ~]# 

3.3 RedHat Linux

代码如下:

[root@getlnx05 ~]# cat /etc/redhat-release 

Red Hat Enterprise Linux Server release 5.7 (Tikanga)

[root@getlnx05 ~]# cat /etc/*release

Red Hat Enterprise Linux Server release 5.7 (Tikanga)

[root@getlnx05 ~]# ls /etc/*release

/etc/redhat-release

[root@getlnx05 ~]#

4 rpm -q redhat-release命令查看，只适用于Redhat Linux

代码如下:

[root@getlnx05 ~]# rpm -q redhat-release 

redhat-release-5Server-5.7.0.3
