近日,准备给某一客户企业部署nagios监控系统,于是在其IBM服务器上最小化安装了Centos 6.3(64bit),却发现刚安装完的系统yum仓库更新不了。提示报错信息:
[root@nagios-server ~]# yum update –y Loaded plugins: fastestmirror 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 [root@nagios-server ~]# nslookup mirrorlist.centos.org ;; connection timed out; no servers couldbe reached 到这里发现问题了,域名解析不了,yum的配置文件里指向的域名就识别不了了。重新设置下dns指向。
