不知道有没有跟我一样的小伙伴，在使用yum安装软件时，发现无法正常使用yum安装软件包，下面出现几句英语提示。在使用rpm时也无法正常的使用。其实 是rpm数据库崩溃导致的 下面就简单的介绍一下怎么回复，让其正常的工作，很简单几个命了即可。
1. 出现错误提示，这时我们需要认真的阅读下面的提示，不要乱找原因
[root@centos7 yum.repos.d]# vim YUM.repo
[root@centos7 yum.repos.d]# yum repolist
error: rpmdb: BDB0113 Thread/process 6396/140171373643584 failed: BDB1507 Thread died in Berkeley DB library
error: db5 error(-30973) from dbenv->failchk: BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db5 – (-30973)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:
Error: rpmdb open failed
2.跟着提示cd /var/lib/rpm 下 查看文件 删除_db.* 所有文件
[root@centos7 yum.repos.d]# cd /var/lib/rpm
[root@centos7 rpm]# ls
Basenames __db.001 __db.003 Group Name Packages Requirename Sigmd5
Conflictname __db.002 Dirnames Installtid Obsoletename Providename Sha1header Triggername
[root@centos7 rpm]# rm _db.* -rf
3.删除后 用rpm –rebuilddb 进行数据文件回复
[root@centos7 rpm]# rpm –rebuilddb
[root@centos7 rpm]# ls
Basenames Dirnames Installtid Obsoletename Providename Sha1header Triggername
Conflictname Group Name Packages Requirename Sigmd5
4.用yum update 更新数据即可
[root@centos7 rpm]# yum update
