最近在一台linux服务器上，执行rpm -qa命令时，报如下错误：
[root@qq_5201351 ~]# rpm -qa error: rpmdb: BDB0113 Thread/process 1685/139832756086336 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 error: rpmdb: BDB0113 Thread/process 1685/139832756086336 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 [root@qq_5201351 ~]#
通过各种资料查询才知道，原因是系统已经安装的rpm包数据信息-数据库损坏
解决方法，重新构建rpm信息数据库：
[root@qq_5201351 ~]# cp -a /var/lib/rpm /var/lib/rpm.bak.202201 [root@qq_5201351 ~]# cd /var/lib/rpm [root@qq_5201351 ~]# rm -f __db.* [root@qq_5201351 ~]# rpm --rebuilddb
然后再次执行rpm -qa 命令进行查询，就正常查询出系统中安装的rpm包软件了，问题解决~
