藍隊云小課堂：

安裝軟件包的時候，被手動終止可能會導致rpm數據庫被損壞

報錯信息：

[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

按照下面的方法進行重建

rpm --rebuilddb
yum clean all
