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 (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、查看当前操作系统发行版信息
cat /etc/issue 或 cat /etc/redhat-release
$ cat /etc/issue S Kernel 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 processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 45 model name : Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHz stepping : 7 microcode : 0xffffffff cpu MHz : 2199.998 cache size : 20480 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : 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 xsaveopt bogomips : 4399.99 clflush size : 64 cache_alignment : 64 address sizes : 44 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 45 model name : Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHz stepping : 7 microcode : 0xffffffff cpu MHz : 2199.998 cache size : 20480 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 apicid : 1 initial apicid : 1 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : 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 xsaveopt bogomips : 4399.99 clflush size : 64 cache_alignment : 64 address sizes : 44 bits physical, 48 bits virtual power 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 -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
