centos如何查看版本

查看centos系統版本的方法：

推薦：《centos使用教程》

1、使用lsb_release -a命令查看

[root@centos6?~]#?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 Description:????CentOS?release?6.9?(Final) Release:????6.9 Codename:????Final

但是，centos7.3里沒有lsb_release命令。

2、使用cat /etc/os-release命令打開文件查看

[root@centos7?app]#?cat?/etc/os-release? NAME="CentOS?linux" VERSION="7?(Core)" ID="centos" ID_LIKE="rhel?fedora" VERSION_ID="7" PRETTY_NAME="CentOS?Linux?7?(Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/"  CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7"

3、使用cat /etc/redhat-release（/etc/centos-release）命令查看

[root@centos6?~]#?cat?/etc/redhat-release? CentOS?release?6.9?(Final) [root@centos7?app]#?cat?/etc/redhat-release? CentOS?Linux?release?7.3.1611?(Core)

4、使用rpm -q centos-release命令查看

[root@centos6?~]#?rpm?-q?centos-release centos-release-6-9.el6.12.3.x86_64 [root@centos7?app]#?rpm?-q?centos-release centos-release-7-3.1611.el7.centos.x86_64
