1、前提条件：安装软件包的时候，被我手动终止了
[root@dhcp yum.repos.d]# yum clean all
rpmdb: Thread/process 4541/140619363587840 failed: Thread died in Berkeley DB library
error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db3 - (-30974)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:
Error: rpmdb open failed
[root@dhcp yum.repos.d]# yum makecache
rpmdb: Thread/process 4541/140619363587840 failed: Thread died in Berkeley DB library

2、根据提示可以知道rpm数据库被损坏，如是按照下面的方法进行重建
[root@dhcp yum.repos.d]# cd /var/lib/rpm/
[root@dhcp rpm]# ls
Basenames __db.004 Name Pubkeys Triggername
Conflictname Dirnames Obsoletename Requirename
__db.001 Filedigests Packages Requireversion
__db.002 Group Providename Sha1header
__db.003 Installtid Provideversion Sigmd5
[root@dhcp rpm]# rm __db.* -rf [root@dhcp rpm]# rpm --rebuilddb [root@dhcp rpm]# yum clean all
