查看Linux系统版本信息的方法小结

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
