Fixing the CentOS issue: Cannot find a valid baseurl for repo: update
The issue stems from yum's inability to utilize the nifty mirroring system setup for CentOS. To resolve it, you need to manually insert your actual DNS servers into /etc/resolv.conf
So, if you're behind a home network, you'll need to determine your ISP's nameservers and insert one per line into /etc/resolv.conf like this:
nameserver 202.96.209.133nameserver 172.01.14.14nameserver 172.01.14.28Trackbackhttp://www.jroller.com/page/agileanswers?entry=fixing_the_centos_issue_cannot
簡單來說，碰到 CentOS 更新失敗
錯誤訊息類似：
請馬上檢查你的網路設定檔
例如：/etc/resolv.conf
確定網路無誤、 DNS 無誤的話，應該就可以解決這類問題囉。
