以下操作在centos系統上實作,有些方式可能隻适用centos/redhat版本系統
- uname -a |uname -r檢視核心版本資訊
[root@node1 ~]# uname -a
Linux node1 2.6.32-573.el6.x86_64 #1 SMP Thu Jul 23 15:44:03 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
[root@node1 ~]# uname -r
2.6.32-573.el6.x86_64
- cat /proc/version 檢視核心版本gcc版本
[root@node1 ~]# cat /proc/version
Linux version 2.6.32-573.el6.x86_64 ([email protected]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC) ) #1 SMP Thu Jul 23 15:44:03 UTC 2015
- lsb_release -a 列出所有版本資訊,檢視系統發行版本資訊,centos版本如果沒有此指令可以執行yum install lsb安裝
[root@node1 ~]# 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 6.7 (Final)
Release: 6.7
Codename: Final
- cat /etc/issue 檢視系統版本
[root@node1 ~]# cat /etc/issue
CentOS release 6.7 (Final)
Kernel \r on an \m
- centos系統執行cat /etc/redhat-release 檢視系統版本資訊
[root@node1 ~]# cat /etc/redhat-release
CentOS release 6.7 (Final)
- 執行 getconf LONG_BIT可以檢視linux系統位數
[root@node1 ~]# getconf LONG_BIT
