如何查看linux版本的型号

Linux系统如何查看版本信息1、查看当前 *** 作系统内核信息uname -a$ uname -aLinux 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 *** 作系统版本信息cat /proc/version$ cat /proc/versionLinux version 3.10.0-693.21.1.el7.x86_64 (builder@kbuilder.dev.centos.org) (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 *** 作系统发行版信息cat /etc/issue 或 cat /etc/redhat-release$ cat /etc/issue\SKernel \r on an \m $ cat /etc/redhat-releaseCentOS 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/cpuinfoprocessor: 0vendor_id: GenuineIntelcpu family: 6model: 45model name: Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHzstepping: 7microcode: 0xffffffffcpu MHz: 2199.998cache size: 20480 KBphysical id: 0siblings: 2core id: 0cpu cores: 2apicid: 0initial apicid: 0fpu: yesfpu_exception: yescpuid level: 13wp: yesflags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss ht syscall nx pdpe1gb rdtscp lm constant_tsc rep_good nopl xtopology eagerfpu pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 popcnt aes xsave avx hypervisor lahf_lm xsaveoptbogomips: 4399.99clflush size: 64cache_alignment: 64address sizes: 44 bits physical, 48 bits virtualpower management: processor: 1vendor_id: GenuineIntelcpu family: 6model: 45model name: Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHzstepping: 7microcode: 0xffffffffcpu MHz: 2199.998cache size: 20480 KBphysical id: 0siblings: 2core id: 1cpu cores: 2apicid: 1initial apicid: 1fpu: yesfpu_exception: yescpuid level: 13wp: yesflags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss ht syscall nx pdpe1gb rdtscp lm constant_tsc rep_good nopl xtopology eagerfpu pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 popcnt aes xsave avx hypervisor lahf_lm xsaveoptbogomips: 4399.99clflush size: 64cache_alignment: 64address sizes: 44 bits physical, 48 bits virtualpower management: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 -aLSB 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-noarchDistributor ID:CentOSDescription:CentOS Linux release 7.4.1708 (Core)Release:7.4.1708Codename:Core

二。查看linux版本：

1) 登录到服务器执行 lsb_release -a ,即可列出所有版本信息,例如:

[root@SOR_SYS ~]# lsb_release -a

LSB Version::core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch

Distributor ID: RedHatEnterpriseAS

Description:Red Hat Enterprise Linux AS release 4 (Nahant Update 4)

Release:4

Codename: NahantUpdate4

[root@SOR_SYS ~]#

注:这个命令适用于所有的linux，包括Redhat、SuSE、Debian等发行版。

2) 登录到linux执行cat /etc/issue,例如如下:

[root@SOR_SYS ~]# cat /etc/issue

Red Hat Enterprise Linux Server release 5.6 (Tikanga)

Kernel \r on an \m

[root@SOR_SYS ~]#

3) 登录到linux执行cat /etc/redhat-release ,例如如下:

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

Red Hat Enterprise Linux AS release 4 (Nahant Update 4)

[root@SOR_SYS ~]#

注:这种方式下可以直接看到具体的版本号，比如 AS4 Update 1

4)登录到linux执行rpm -q redhat-release ,例如如下:

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

redhat-release-5Server-5.6.0.3

[root@SOR_SYS ~]#

注:这种方式下可看到一个所谓的release号，比如上边的例子是5

这个release号和实际的版本之间存在一定的对应关系，如下：

redhat-release-3AS-1 ->Redhat Enterprise Linux AS 3

redhat-release-3AS-7.4 ->Redhat Enterprise Linux AS 3 Update 4

redhat-release-4AS-2 ->Redhat Enterprise Linux AS 4

redhat-release-4AS-2.4 ->Redhat Enterprise Linux AS 4 Update 1

redhat-release-4AS-3 ->Redhat Enterprise Linux AS 4 Update 2

redhat-release-4AS-4.1 ->Redhat Enterprise Linux AS 4 Update 3

redhat-release-4AS-5.5 ->Redhat Enterprise Linux AS 4 Update 4

另:第3)、4)两种方法只对Redhat Linux有效

5) [root@SOR_SYS ~]# file /bin/bash

/bin/bash: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped

[root@SOR_SYS ~]#

6) [root@SOR_SYS ~]# file /bin/cat

/bin/cat: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped

[root@SOR_SYS ~]#

centos下查看内核版本： 1,如下命令适合于linux所有发行版本或其它unix版本比如 FreeBSD, OpenBSD, Solaris, HP UX etc. $ uname -r 2,另一种通用的方法: $ uname -mrsn
