出现的问题

问题1 ，
导入Oracle的YUM后，无法安装RPM包
解决方法：
签名不对，需要把gpgcheck=1 改成gpgcheck=0

问题2
存在1个Inhibitors:，查看相关日志，发现提示有多个linux 7的YUM源，
解决方法：
/etc/yum.repos.d下，把7的yum源文件，重命名

[grid@node19c02 yum.repos.d]$ ls -lrt
total 84
-rw-r--r--. 1 root root   120 Apr 25  2020 local.repo_20250922
-rw-r--r--. 1 root root   358 Apr 25  2020 redhat.repo_20250922

-rw-r--r--  1 root root   941 Sep 22 14:53 uek-ol8.repo
[grid@node19c02 yum.repos.d]$

问题3
存在1个Inhibitors，查看相关日志，发现一些包有冲突
解决方法：
卸载有冲突的包

问题4
因为原来的OS是redhat，使用了Oracle Linux的源后，虽然update了，但是kernel还是redhat的，不是oracle uek的kernel
解决方法：安装UEK的kernel ， yum install kernel-uek
