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

標籤：

這個錯誤引起主要是因為環境讀取不到yun引起的可以考慮/etc/sysconfig/network-scripts/ifcfg-eth0 配置出錯導致網路不通。或者/etc/resolv.conf的DNS配置出錯。或者可以考慮清楚yum緩衝影響（yum clean all）

 

（下面是網上找到比較有用資料）

今天在linux環境通過yum安裝軟體報了以下錯誤：

[[email protected] yum.repos.d]# yum install ncurses devel -yLoaded plugins: fastestmirror, securityLoading mirror speeds from cached hostfileCould not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was14: PYCURL ERROR 6 - "Couldn‘t resolve host ‘mirrorlist.centos.org‘"Error: Cannot find a valid baseurl 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：

[[email protected] ~]# vim /etc/resolv.confnameserver 8.8.8.8nameserver 202.106.0.20

重啟網路服務

[[email protected] ~]# /etc/init.d/network restartShutting down interface eth0:                              [  OK  ]Shutting down loopback interface:                          [  OK  ]Bringing up loopback interface:                            [  OK  ]Bringing up interface eth0:  Determining if ip address 192.168.1.202 is already in use for device eth0...                                                           [  OK  ]

重新yum安裝，正常
