如何快速查看linux的发行版信息

思路一：

在CentOS中想查看发行版信息，输入了lsb_release -a 命令却报错了，通过输入以下命令进行安装

yum install redhat-lsb -y

然后继续查看发行版信息

[root@localhost ~]# 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 7.2. (Core)

思路二：

[root@localhost Desktop]# hostnamectl
