Yum Error Error:cannot find a valid baseurl for repo:base

Recently, when installing the RPM package for MySQL, there was a problem

When using the command:

Vim./resolv.conf

The following error occurred:

Loading mirror speeds from cached hostfile

Could not retrieve mirrorlist Http://mirrorlist.centos.org/?release=6&arch=i386&repo=os error was
14:pycurl ERROR 6-"couldn ' t resolve Host ' mirrorlist.centos.org '"
Error:cannot find a valid baseurl for repo:base

The workaround is as follows (modify DNS configuration)

Vi/etc/resolv.conf

This file was last added: NameServer 8.8.8.8

If no VI editor is available:

echo "NameServer 8.8.8.8" >>/etc/resolv.conf

Then ping www.baidu.com

Can ping through, no more unknow host

OK, installation dependent,

Yum Install ld-linux.so.2

Finally appear compelete can
