Solve Couldn't resolve host 'into list .centos.org

The following error is reported when you install software through yum in linux today:

[root@multi-mysqlyum.repos.d] #yuminstallncursesdevel-y Loadedplugins:fastestmirror,security Loadingmirrorspeedsfromcachedhostfile Couldnotretrievemirrorlisthttp: //mirrorlist .centos.org/?release=6&arch=x86_64&repo=oserrorwas 14:PYCURLERROR6- "Couldn'tresolvehost'mirrorlist.centos.org'" Error:Cannot find avalidbaseurl for repo:base

Literally, the list.centos.org address cannot be resolved. It should be related to the dns Network configuration. The final solution is to add the IP address of the DNS server in the DNS domain name resolution configuration file:

[root@multi-mysql~] #vim/etc/resolv.conf nameserver8.8.8.8 nameserver202.106.0.20

Restart NETWORK SERVICE

Install yum again. Normal
