YUM Hangs And Won’t Respond

keyword: yum hangs and won’t respond

ssh 到测试机更新subversion1.7, 需要删除之前的老版本,发现yum命令没有响应,提示 “yum hangs and won’t respond”,
初步解决办法更新yum库缓存数据:

rm -f /var/lib/rpm/__*
rpm --rebuilddb -v -v   
yum clean all

If that did not work, you can set a debug level, error level and timeout for yum in /etc/yum.conf:

debugelevel=1
errorlevel=1
timeout=1

The timeout is standard 30 seconds. So if a repository does not respond, the error takes 30 seconds to appear. Also try using yum without the plugins (like fastest mirror and priorities) with the option –noplugins. Now starting yum again should give you more info faster. Test with:

yum --verbose --noplugins info
