这里有常用的三个办法。

一、uname -a

uname -a

indude[root@indude ~]# uname -a
Linux iZ7xv6rb1v80kgjdqdb3w6Z 3.10.0-1160.99.1.el7.x86_64 #1 SMP Wed Sep 13 14:19:20 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
[root@iZ7xv6rb1v80kgjdqdb3w6Z ~]#

二、cat /proc/version

cat /proc/version

[root@indude ~]# cat /proc/version
Linux version 3.10.0-1160.99.1.el7.x86_64 (mockbuild@kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) ) #1 SMP Wed Sep 13 14:19:20 UTC 2023
[root@indude ~]# 

三、cat /etc/redhat-release

cat /etc/redhat-release

[root@indude ~]# cat /etc/redhat-release
