- vim /etc/yum.repos.d/CentOS-Base.repo
- and comment out(put #) on all ‘mirrorlist’ and then uncomment (take out #) on all baseurl then replace the URL (official centos.org, do not use 3rd parties, they are dangerous) as following on all ‘baseurl’ lines
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
baseurl=https://vault.centos.org/6/os/$basearch/
You are all set.
