风哥提示：
本文档介绍Linux系统日常巡检与合规检查的方法和最佳实践。
Part01-系统状态巡检
1.1 系统基础信息检查
[root@fgedu-server ~]# cat /etc/redhat-release
Red Hat Enterprise Linux release 9.2 (Plow)
# 检查内核版本
[root@fgedu-server ~]# uname -a
Linux fgedu-server 5.14.0-284.11.1.el9_2.x86_64 #1 SMP Tue Mar 14 18:05:47 EDT 2026 x86_64 x86_64 x86_64 GNU/Linux
# 检查主机名
[root@fgedu-server ~]# hostnamectl
