不知道有沒有跟我一樣的小伙伴，在使用yum安裝軟件時，發現無法正常使用yum安裝軟件包，下面出現幾句英語提示。在使用rpm時也無法正常的使用。其實 是rpm數據庫崩潰導致的 下面就簡單的介紹一下怎么回復，讓其正常的工作，很簡單幾個命了即可。
1. 出現錯誤提示，這時我們需要認真的閱讀下面的提示，不要亂找原因
[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.跟著提示cd /var/lib/rpm 下 查看文件 刪除_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.刪除后 用rpm –rebuilddb 進行數據文件回復
[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 更新數據即可
[root@centos7 rpm]# yum update
