查看Linux版本信息

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

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

 

1.2 Centos Linux

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

 

1.3 RedHat Linux

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

 

2: lsb_release -a 命令查看

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

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

[root@DB-Server etc]# cat /etc/*release
Enterprise Linux Enterprise Linux Server release 5.7 (Carthage)
Oracle Linux Server release 5.7

[root@DB-Server etc]# ls  /etc/*lease
/etc/enterprise-release  /etc/oracle-release  /etc/redhat-release
[root@DB-Server etc]#

 

3.2 Centos Linux

[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

3.3 RedHat Linux

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

[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

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