一、查看系统版本信息

(1)查看系统详细信息

使用uname -a命令,可以查看系统版本的详细信息,如下所示:Linux gwmaster 3.10.0-514.26.2.el7.x86_64 #1 SMP Tue Jul 4 15:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

(2)查看当前运行的系统信息

使用cat /proc/version命令Linux version 3.10.0-514.26.2.el7.x86_64 ([email protected]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC) ) #1 SMP Tue Jul 4 15:04:05 UTC 2017

(3)查看发行版本

使用cat /etc/issue或cat /etc/redhat-release命令CentOS Linux release 7.2.1511 (Core)

(4)查看发行详细信息

使用lsb_release -a命令,如果提示找不到命令lsb_release,则需要手动使用命令yum install redhat-lsb -y安装相应的软件包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

(2)使用命令file /bin/ls/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=aa7ff68f13de25936a098016243ce57c3c982e06, stripped
