The reason why rpm is damaged: the database needs to be rebuilt.

Solution: clear the original link through the command and re-establish it.

[root@localhost ~]# rm -rf /var/lib/rpm/_db*  #Delete the original
[root@localhost ~]# rpm --rebuilddb # New
[root@localhost ~]# yum clean all # Clear all yum caches

It can be used normally at present
