在centos6.5上使用yum源安装Apache，报错Loaded plugins: fastestmirror, security Could not retrieve mirrorlist

遇到的问题：安装Apache时报错
Loaded plugins: fastestmirror, security Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was 12: Timeout on http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os: (28, ‘Operation too slow.

1.后来发现网卡配置信息中没有写入DNS（域名系统），编辑对应的网卡

vim /etc/sysconfig/network-scripts/ifcfg-eth0

免费的域名系统
114.114.114.114
8.8.8.8

2.重启网络服务

ifdown ifcfg-eth0
ifup ifcfg-eth0

如果实在实际工作中，最好不要用service network restart。若是自己的电脑做实验，可以使用service network restart。

3.重新下载httpd

yum install httpd
