Linux系統查看系統版本命令

如下操做在centos系統上實現，有些方式可能只適用centos/redhat版本系統

1. uname -a |uname -r查看內核版本信息

[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

1. cat /proc/version 查看內核版本gcc版本

[root@node1 ~]# cat /proc/version
Linux version 2.6.32-573.el6.x86_64 (mockbuild@c6b9.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC) ) #1 SMP Thu Jul 23 15:44:03 UTC 2015

1. lsb_release -a 列出全部版本信息，查看系統發行版本信息，centos版本若是沒有此命令能夠執行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

Codename:       Final

1. cat /etc/issue 查看系統版本

[root@node1 ~]# cat /etc/issue
CentOS release 6.7 (Final)
Kernel \r on an \m

1. centos系統執行cat /etc/redhat-release 查看系統版本信息

[root@node1 ~]# cat /etc/redhat-release
CentOS release 6.7 (Final)

1. 執行 getconf LONG_BIT能夠查看linux系統位數

[root@node1 ~]# getconf LONG_BIT
