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。
查看Linux内核版本的命令
方法一:
命令: uname -a
作用: 查看系统内核版本号及系统名称
方法二:
命令: cat /proc/version
作用: 查看目录"/proc"下version的信息,也可以得到当前系统的内核版本号及系统名称
补充说明:
/proc文件系统,它不是普通的文件系统,而是系统内核的映像,也就是说,该目录中的文件是存放在系统内存之中的,它以文件系统的方式为访问系统内核数据的操作提供接口。而我们使用命令“uname -a"的信息就是从该文件获取的,当然用方法二的命令直接查看它的内容也可以达到同等效果.另外,加上参数"a"是获得详细信息,如果不加参数为查看系统名称。

2: lsb_release -a 命令查看
2.1 Oracle Linux
[root@DB-Server ~]# lsb_release -a

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
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
[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
[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
[root@getlnx05 ~]# rpm -q redhat-release
redhat-release-5Server-5.7.0.3
