拿到一台服务器，再部署项目时，用yum安装软件时，报错如下：

error: rpmdb: BDB0113 Thread/process 9480/140323413588032 failed: BDB1507 Thread died in Berkeley DB library

如图：

字面意思rpmdb开启失败，运行rpm -qa，也报错，同样的问题，rpmdb的问题

解决：
1.进到rpm目录

cd /var/lib/rpm

可以看到几个_db开头的几个文件，如图：

2.删除_db开头的文件

rm -rf _db*

3.重新构建

rpm --rebuilddb

好了，执行yum和rpm命令可以了！
