【转】解决yum安装软件报Couldn't resolve host 'mirrorlist.centos.org问题

转自：http://blog.51cto.com/oldcat1981/1719825

今天在linux环境通过yum安装软件报了以下错误：

[root@multi-mysql yum.repos.d]# yum install ncurses devel -y

Loaded plugins: fastestmirror, security

Loading mirror speeds from cached hostfile

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was

14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'"

Error: Cannot find a valid baseurl for repo: base

从字面意义上看是不能解析mirrorlist.centos.org这个地址，应该是跟dns网络配置有关系，最后解决方法是在DNS域名解析的配置文件增加DNS服务器的IP地址：

[root@multi-mysql ~]# vim /etc/resolv.conf

nameserver 8.8.8.8

nameserver 202.106.0.20

注：我只写了第一句就可以了……

重启网络服务

[root@multi-mysql ~]# /etc/init.d/network restart

Shutting 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安装，正常

[root@multi-mysql ~]# yum install nmap -y

Loaded plugins: fastestmirror, security
