linux oracle 查看版本号 Linux下如何查看版本信息

1、uname -a (Linux查看版本当前操作系统内核信息)

[root@izuf66j2kiq945yl5br4ubz yum.repos.d]# uname -a

Linux izuf66j2kiq945yl5br4ubz 3.10.0-514.26.2.el7.x86_64 #1 SMP Tue Jul 4 15:04:05 UTC x86_64 x86_64 x86_64 GNU/Linux

2、cat /proc/version (Linux查看当前操作系统版本信息)

[root@izuf66j2kiq945yl5br4ubz yum.repos.d]# cat /proc/version

Linux version 3.10.0-514.26.2.el7.x86_64 (builder@kbuilder.) (gcc version 4.8.5 0623 (Red Hat 4.8.5-11) (GCC)

) #1 SMP Tue Jul 4 15:04:05 UTC

3、cat /etc/issue 或cat /etc/redhat-release(Linux查看版本当前操作系统发行版信息)

[root@izuf66j2kiq945yl5br4ubz yum.repos.d]# cat /etc/redhat-release

CentOS Linux release 7.3.1611 (Core)

4、cat /proc/cpuinfo (Linux查看cpu相关信息，包括型号、主频、内核信息等)

[root@izuf66j2kiq945yl5br4ubz yum.repos.d]# cat /proc/cpuinfo

5、getconf LONG_BIT (Linux查看版本说明当前CPU运行在32bit模式下， 但不代表CPU不支持64bit

[root@izuf66j2kiq945yl5br4ubz yum.repos.d]# getconf LONG_BIT

64

6、 lsb_release -a

[root@izuf66j2kiq945yl5br4ubz yum.repos.d]# lsb_release -a
