yum执行失败-修复rpm数据库（Fix rpmdb Thread died in Berkeley DB library）

问题

当在CentOs上面执行yum安装操作时，出现以下错误，此时需要做以下操作来解决此问题。

[root@centos ~]# yum
error: rpmdb: BDB0113 Thread/process 16994/140307288778816 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

以上错误意味着rpm 数据库被毁坏了

解决

请执行以下恢复步骤命令，并重建rpm数据库

mkdir /var/lib/rpm/backup
cp -a /var/lib/rpm/__db* /var/lib/rpm/backup/
rm -f /var/lib/rpm/__db.[0-9][0-9]*
rpm --quiet -qa
rpm --rebuilddb
yum clean all

结果

[root@centos ~]# yum makecache
