刚才为了写有关yum的博客，我在我的CentOS7操作系统使用yum -h想把里边的信息复制出来整理一下大家讲一下yum的具体操作，由于我不小心把yum -h里边的内容给复制到shell命令行了，这下子倒霉了，不断的有yum …… 的命令出现，于是我不断使用ctrl+C快捷键进行命令终止操作，当所有操作都终止了，以下问题出现了：
[[email protected] ~]# yum clean all
error: rpmdb: BDB0113 Thread/process 58171/139859184105280 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

[[email protected] ~]# yum grouplist

error: cannot open Packages index using db5 - (-30973)

CRITICAL:yum.main:

[[email protected] ~]# yum --help
error: rpmdb: BDB0113 Thread/process 58171/139859184105280 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
以上所有用到yum的操作都有一个同样的问题那就是：
error: rpmdb: BDB0113 Thread/process 58171/139859184105280 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、根据提示我们可以知道rpm数据库在yum安装过程中使用Ctrl+C给损坏了，需要我们重新构建，下面是重新构建的方法及步骤：
[[email protected] Packages]# cd /var/lib/rpm
[[email protected] rpm]# ls
Basenames __db.001 __db.003 Group Name Packages Requirename Sigmd5
Conflictname __db.002 Dirnames Installtid Obsoletename Providename Sha1header Triggername
[[email protected] rpm]# rm __db.* -rf #删除rpm库
[[email protected] rpm]# rpm --rebuilddb #rpm的重新构建命令
[[email protected] rpm]# yum clean all #用yum clean all重新测试

Cleaning up list of fastest mirrors
[[email protected] rpm]# yum grouplist #用yum grouplist 命令重新测试
