今天安装FUSE的时候系统报错，Error: rpmdb open failed，刚开始以为是命令行的问题，结果发现安装什么都是这样的提示：[root@VM-4-5-centos ~]# yum -y install fuse error: rpmdb: BDB0113 Thread/process 29064/140040672127040 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解决办法如下：首先清除掉缓存，之后再重建就可以了rm -f /var/lib/rpm/__db* rpm --rebuilddb
