解決方法
vim /etc/yum.repos.d/epel.repo

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearc
h
failovermethod=priority
enabled=1
#enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 
將enabled=1先改為enabled=0
然後命令列執行

yum install ca-certificates，安裝成功後，將enabled重新改為1，再行

yum install -y XXXX可以正常安裝了
