解决CentOS在执行yum命令时报错"Error: rpmdb open failed"

今天在日常进行CentOS操作的时候,不知为何yum -y install xxx命令突然卡死不动,Ctrl+C取消执行也无解,遂关闭SSH重新建立连接,然而再次重新执行yum -y install xxx命令时却报如下错误:

...

初步判断应该是进程号为27970的那个假死了,即使刚才SSH关闭了也并没有杀掉他,遂干脆利落的执行了kill -9 27970直接杀死,后再执行yum -y install xxx命令,结果又有报错:

...
[email protected]:~>yum -y install xxx

哦豁,凉了,rpmdb本地数据存储文件炸了……不过好在有解决方法。

执行如下命令,清理YUM仓库本地数据存储文件:

mv /var/lib/rpm/__db* /tmp;

执行如下命令,清理yum缓存:

rpm --rebuilddb;
yum clean all

大功告成。

现在细想一下,yum当时有可能是因为网络问题假死,可能再等等就好了,不过毕竟当时有点着急,以后得注意下。
