如何查看linux版本的型号

Posted 2023-04-30

参考技术A Linux系统如何查看版本信息
1、查看当前操作系统内核信息
uname -a
$ uname -a

Linux vm-web 3.10.0-693.21.1.el7.x86_64 #1 SMP Wed Mar 7 19:03:37 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

2、查看当前操作系统版本信息
cat /proc/version
$ cat /proc/version
Linux version 3.10.0-693.21.1.el7.x86_64 ([e-mail]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 SMP Wed Mar 7 19:03:37 UTC 2018

3、查看当前操作系统发行版信息
cat /etc/issue 或 cat /etc/redhat-release
$ cat /etc/issue
\S
Kernel \r on an \m

$ cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)

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

5、列出所有版本信息
lsb_release -a
$ lsb_release -a
-bash: lsb_release: command not found
出现command not found说明没安装lsb_realease，可以执行命令yum install -y redhat-lsb安装lsb_realease，安装完成后，版本信息如下：
$ lsb_release -a
LSB Version: :core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch
Distributor ID: CentOS
Description: CentOS Linux release 7.4.1708 (Core)
Release: 7.4.1708
Codename: Core

Linux下如何查看版本信息

1、Linux查看版本当前操作系统内核信息

uname －a  

2、Linux查看当前操作系统版本信息

cat /proc/version

 3、Linux查看版本当前操作系统发行版信息

cat /etc/issue  或cat /etc/redhat-release

 4、Linux查看cpu相关信息，包括型号、主频、内核信息等

cat /proc/cpuinfo

5. CentOS  6/7通用的查看系统版本

cat /etc/redhat-release、  rpm -q centos-release、cat /etc/issue
