解決Couldn't resolve host 'mirrorlist.centos.org

解決Couldn't resolve host 'mirrorlist.centos.org

今天在linux環境通過yum安裝軟體報了以下錯誤：

[root@multi-mysqlyum.repos.d] #yuminstallncursesdevel-y Loadedplugins:fastestmirror,security Loadingmirrorspeedsfromcachedhostfile Couldnotretrievemirrorlisthttp: //mirrorlist .centos.org/?release=6&arch=x86_64&repo=oserrorwas 14:PYCURLERROR6- "Couldn'tresolvehost'mirrorlist.centos.org'" Error:Cannot find avalidbaseurl for repo:base

從字面意義上看是不能解析mirrorlist.centos.org這個地址，應該是跟dns網路設定有關係，最後解決方案是在DNS網域名稱解析的設定檔增加DNS伺服器的IP地址：

[root@multi-mysql~] #vim/etc/resolv.conf nameserver8.8.8.8 nameserver202.106.0.20

重啟網路服務

[root@multi-mysql~] #/etc/init.d/networkrestart Shuttingdowninterfaceeth0:[OK] Shuttingdownloopbackinterface:[OK] Bringinguploopbackinterface:[OK] Bringingupinterfaceeth0:Determining if ipaddress192.168.1.202isalready in use for deviceeth0... [OK]

重新yum安裝，正常
