一、問題描述
使用yum安裝軟件時出現Error: rpmdb open failed，報錯信息顯示rpm數據庫被損壞。
二、解決方案
重建rpm數據庫。
[root@localhost yum.repos.d]# cd /var/lib/rpm
[root@localhost rpm]# ls
Basenames __db.001 __db.003 Group Name Packages Requirename Sigmd5
Conflictname __db.002 Dirnames Installtid Obsoletename Providename Sha1header Triggername
[root@localhost rpm]# rm __db.* -rf
[root@localhost rpm]# ls
Basenames Dirnames Installtid Obsoletename Providename Sha1header Triggername
Conflictname Group Name Packages Requirename Sigmd5
[root@localhost rpm]# rpm --rebuilddb
[root@localhost rpm]# yum clean all
已加載插件：langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
正在清理軟件源： local nginx
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
三、結果驗證
